Stack usage details with armclang TF-A build

by mail2diggi＠gmail.com

Dear all, we want analyze stack usage details when we build TF-A for armclang compiler but we are not able generate stack usage details. sorry for long thread and question please go through and suggest way forward to perform stack analysis with TF-A armclang build. as per https://trustedfirmware-a.readthedocs.io/en/latest/getting_started/initial-… (section 2.3) when CC is set to armclang, GCC linker is used default (since the TF-A build system doesn’t currently support Arm Scatter files) So when we try to generate stack usage details we will not be able to use GCC -fstack-usage and -fdump-ipa-calgraph since CC is set to armclang and these flags will be un-recognized. Since we are building this for armclang we attempted to use following armlinker flags along with -g compiler flag (refer link:https://developer.arm.com/documentation/100748/0607/writing-optimized-…). --info=stack, --calgrapth, --calgraph_output=text But we end up with unrecognized options error for --info=stack, --calgrapth, --calgraph_output=text This error occurs because GCC linker is used default as per above link section 2.3 (since the TF-A build system doesn’t currently support Arm Scatter files) So we end up with not having stack usage details generated. Q1: Any suggestion to generate stack usage when CC=armclang and GCC linker is used by default. Q2: if we attempt to change LD with armlink we will end up with "Fatal error: L6031U: Could not open scatter description file." https://trustedfirmware-a.readthedocs.io/en/latest/getting_started/initial-… section 2.3 suggest that "that the default linker may be manually overridden using the LD variable" can you please let us know how to override LD with armlinker without getting scatter issue. Using: armclang 6.6.2 version. Thank you Shivakumar Diggi

Function parameter should not be modified.

by Nithin G

Hello, In the file common/bl_common.c and other related files, there are instances where function parameters are being modified. This leads to violations when running the Coverity MISRA-C analysis for the ZynqMP platform. To address this issue a new variable is declared and used to store the value from the argument in the code. Is it possible to fix by taking a new variable? Please provide your suggestions. Regards, Nithin G

The condition clause of the for loop does not use the loop counter variable.

by Nithin G

Hello, In the file lib/xlat_tables/xlat_tables_common.c and other related files, the condition clause of the for loop does not use the loop counter variable "mm". This leads to violations when running the Coverity MISRA-C analysis for the ZynqMP platform. Addressing this issue added mm as part of loop counter and this belongs to core translational table logic and other violations also related to this. Is it possible to address this issue? Please provide your suggestions. Regards, Nithin G

Function bl31_lib_init() has external linkage but is only used in one translation unit.

by Nithin G

Hello, In the file bl31/bl31_main.c, there is a function named bl31_lib_init with its definition. Simultaneously, the declaration of this function is included in include/bl31/bl31.h since the function bl31_lib_init used only in one translational unit. leading to a violation when running the Coverity MISRA-C analysis for the ZynqMP. Addressing this issue need to remove the declaration of the function from the bl31.h file and making its definition static. To maintain visibility, included a static declaration in the bl31_main.c file. However, it will may impact in future modifications due to the removal of the declaration in bl31.h. Please provide your suggestions. Regards, Nithin

Experimental rust-spmc project release

by Imre Kis

Dear All, We would like to announce that we have published an experimental project called rust-spmc which is a S-EL1 FF-A Secure Partition Manager Core implementation in Rust. We started this as a free time project and now we had the opportunity to publish it on trustedfirmware.org. In its current state it has a partial implementation of the FF-A protocol, and it is able to run the secure partitions of Trusted Services with all tests passing on Arm FVP. It also provides the required compartmentalization between the S-EL0 secure partitions. Please note that the project is experimental (i.e. PoC, not suitable for production) and it is currently not scheduled by Arm for further development. The Rust language is an ideal language for implementing firmware components given its lack of undefined behavior and its memory safety guarantees. Our goal was to demonstrate the capabilities of language in a security critical firmware environment and to gather feedback from partners which could open up the possibility of further development of the project. The repository is available here: https://git.trustedfirmware.org/rust-spmc/rust-spmc.git/ We also prepared a readme with instructions for testing the project: https://git.trustedfirmware.org/rust-spmc/rust-spmc.git/about/ Please reach out to us if you are interested in the project or if you have any questions. Regards, Bálint Dobszay & Imre Kis

rk3328: WARNING: BL31: cortex_a53: CPU workaround for 1530924 was missing!

by Diederik de Haas

When booting my Pine64 Rock64 (rk3328), I see the following warning: WARNING: BL31: cortex_a53: CPU workaround for 1530924 was missing! That warning is present in u-boot 2023.01 and also in 2023.07. Asking on their IRC channel and they indicated it should be fixed in TF-A. In the source code I saw various commits which all seem a variation of 74665119f04de0cd7c735fa741aff607a4a9fde8 titled "Enable workaround for Cortex-A53 erratum 1530924" But such a commit seems to be missing for the rk3328 platform. I guess a patch like this is needed to fix that? ```patch diff --git a/plat/rockchip/rk3328/platform.mk b/plat/rockchip/rk3328/ platform.mk index 5b4766d51..bd86a1cc8 100644 --- a/plat/rockchip/rk3328/platform.mk +++ b/plat/rockchip/rk3328/platform.mk @@ -65,6 +65,7 @@ include lib/libfdt/libfdt.mk # Enable workarounds for selected Cortex-A53 errata ERRATA_A53_855873 := 1 +ERRATA_A53_1530924 := 1 $(eval $(call add_define,PLAT_EXTRA_LD_SCRIPT)) $(eval $(call add_define,PLAT_SKIP_OPTEE_S_EL1_INT_REGISTER)) ``` The Contributor’s Guide indicates that it requires a Microsoft Github account, so I opted to post a patch to this list. Cheers, Diederik PS: https://developer.trustedfirmware.org/ seems to be full of spam; you may want to look into that.

We cannot force Arm features for platforms

by Marcin Juszkiewicz

TL;DR: move Mandatory features to be runtime checked (value 2) Month ago there was changeset from Govindraj Raja merged [1]. The plan was to enable all mandatory features based on architecture version set by plaform (using ARM_ARCH_{MAJOR,MINOR} variables). 1. https://review.trustedfirmware.org/q/topic:%22gr/build_refactor%22 The idea is nice. But only for final products. If you are working on silicon bring up or on virtualization platform (QEMU or other) then you got hit badly... I am working on SBSA Reference Platform in QEMU. It can have one of several cpu models. From old v8.0 cores up to v9.0 ones. And then there is also 'max' core which cannot be mapped to any architecture level because it contains all Arm cpu features QEMU can emulate. We need to support all of them in one TF-A binary. Whenever something fails we have some cpu cores in non-bootable state. We had to enable FGT to get 'max' boot Linux. Now we have to move DIT to be runtime checked to boot anything below Neoverse-V1 at all. And HCX to get 'max' boot Linux again. At current state of TF-A we cannot handle it. Toplevel Makefile includes platform.mk which sets ARM_ARCH_{MAJOR,MINOR} and then make_helpers/arch_features.mk enables mandatory options by setting them to value "1" which means "present, no need to check". Due to this we have those changes in Gerrit: DIT: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/24870 TRF: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/23648 And instead of sending another one to switch FGT, RNG and HCX I decided to write this email. I have spent half of day today bisecting TF-A, booting several tools and operating systems to check how we are and where the problem is. Still have to get Neoverse-N2 booting properly but other than then I got to the point where all cpu cores boot into Linux. We need to change make_helpers/arch_features.mk to stop enabling mandatory features as "present, no need to check" (value '1') but to use runtime check (value '2') instead. This way any platform which contains CPU not yet fully developed can boot TF-A. Or platform where one firmware can boot different cpu models. I am sorry that I bring it so late in release cycle but was unable to use computer for a development for some time.

by kbhuvanacbe＠gmail.com

We have executed below command on terminal to get stack size using ARMCLANG compiler. but we are getting "undefined symbol". armclang --target=arm-arm-none-eabi -march=armv8-a -c -g file.c -o file.o armlink file.o --info=stack armlink file.o --callgraph -o FileImage.axf Could anyone answer me that how to get stack size using ARMCLANG compiler for TFA code.

Minor update to Platform ports requirements

by Govindraj Raja

Hi All / Platform owners, There is a minor update to Platform ports requirements based on patches merged recently. https://trustedfirmware-a.readthedocs.io/en/latest/porting-guide.html#build… So please use correct ARM_ARCH_MAJOR and ARM_ARCH_MINOR from platform makefile or from build options to utilize the 'arch_features.mk' to enable all mandatory features by default. Enabling of optional features remain unchanged and based on availability and need can be enabled from platform makefile. Some of platform port convert examples are as below: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/23463/20/pla… https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/23670/21/pla… -- Thanks, Govindraj.R & Manish Pandey

TF-A Hang on NXP i.MX 8M Plus QuadLite

by Marcel Ziswiler

Hi there We recently got our first batch of i.MX 8M Plus QuadLite based SoMs. While NXP downstream works just fine on them they just hang booting with latest upstream U-Boot (and TF-A). Replacing TF-A with the downstream NXP one made upstream U-Boot work as well. Further debugging TF-A showed imx_gpc_pm_domain_enable() to be the culprit. Looking more specifically I discovered the following so far downstream-only commit [1]. So it looks like in downstream NXP is limiting the to-be-enabled power management domains to HSIOMIX, USB1_PHY and USB2_PHY. Anybody knows why exactly this is done and why this got never upstreamed? Thank you very much for any insights into this matter. [1] https://github.com/nxp-imx/imx-atf/commit/47759cfca10b2286a218062915d4a2808… Cheers Marcel

Suspend to RAM support for K3 J7200

by Thomas Richard

Hello, I just sent a series to gerrit: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/23992. I'm writing this email to add more context to this series, as I didn't find how to to it with gerrit. This series is only the TF-A part to add suspend to RAM support for the TI K3 J7200 target. Some modifications are also needed in Linux kernel, U-Boot (R5 SPL) and DM-Firmware. During the suspend sequence, TF-A save itself in DRAM, in a reserved memory region dedicated to lpm. TF-A will be restored by R5 SPL. We need to save it in DRAM (which will be in retention mode during suspend) because as it runs in SRAM, it will be lost once the SOC is powered-off by the PMIC.

Compile error when SAVE_KEYS=1 in tf-a v2.9.0

by xtaens＠qq.com

Hello everyone, When I used TF-A 2.9.0 (commit b06b509eb2b7f0f4dce1b4133500cf30aa0dcd4a) to compile FVP, I opened the SAVE_KEYS=1 and modified the relevant code to save the key, but the compilation failed. The error message is as follows, SAVE_KEYS=0 compile is normal. It is also normal in lts-v2.8.9.

Usage of assert functions in TFA Code

by Nithin S

Hello, There are multiple occurrences in TFA Code where assert statements are used to handle function arguments. But these assert statements are currently enabled only in debug mode. So, I wanted to know that will there be any harm in continuing to use assert statements in production code as well for handling failures? Regards, Nithin S

by Manish Badarkhe

Hi All, We are currently in the process of preparing for an upcoming release v2.10 [1] and are actively seeking out any deprecated platforms within the TF-A source code. We kindly request all platform owners and contributors to dedicate some time to review the TF-A source code for any platforms that may have been deprecated. If you encounter any platforms that require deprecation but have not yet been labelled as such, we kindly request that you contribute by submitting the required changes to officially mark them as deprecated. You can follow the example provided in [2]. Thank you for your cooperation. [1]: https://trustedfirmware-a.readthedocs.io/en/latest/about/release-informatio… [2]: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/17710 Regards, Manish Badarkhe

#ifdef PLAT_XLAT_TABLES_DYNAMIC in xlat_tables_context.c

by Nagal, Amit

Hi , When I grep for PLAT_XLAT_TABLES_DYNAMIC in /lib/lib/xlat_tables_v2/ , I see most references for PLAT_XLAT_TABLES_DYNAMIC are enclosed in #if directive. Is there any specific reason why only below mentioned reference for PLAT_XLAT_TABLES_DYNAMIC is covered with #ifdef and not under #if . https://github.com/Xilinx/arm-trusted-firmware/blob/master/lib/xlat_tables_… #ifdef PLAT_XLAT_TABLES_DYNAMIC #define MAX_PHYS_ADDR tf_xlat_ctx.pa_max_address #else #define MAX_PHYS_ADDR tf_xlat_ctx.max_pa #endif Regards Amit

Platforms without NS-EL2 component

by Manish Pandey2

Hi, I am writing this email to find out any legacy platforms supports in TF-A (upstream or downstream) which does not have any NS-EL2 component running. Because NS-EL2 is present but unused EL3 also need to do a minimal initialization of EL2. The side effect of this is, TF-A currently has extra code in generic path (e.g. cm_prepare_el3_exit() ) to cater for these platforms which is not required for most others. The most likely reason why TF-A introduced support for systems without NS-EL2 was because of UEFI implementation for Windows which didn't initialize NS-EL2 properly. Given that the UEFI spec has said "Use the highest 64 bit non secure privilege level available" for a long time now we are safe to assume that any UEFI implementation will handover to windows at NS-EL2. (similar to Linux) Considering that there are very few platforms which need this code and to keep backward compatibility, we propose to introduce a macro like "INIT_UNUSED_NS_EL2" and guard the code under this[1]. Keep this flag default disabled and get rid of it( along with code) altogether in next couple of releases, if we are certain that none of the platforms using it. Please let me know if you are aware of any such platform configuration. [1] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/22716 Thanks Manish

EHF + OP-TEE

by brian.neely＠analog.com

Hello, Are EHF and OP-TEE (opteed) designed to work together? I'm seeing some strange behavior when NS interrupts are routed to EL3 as FIQs (due to EHF), but before I dig into it further I wanted to confirm if EHF + OP-TEE is a valid combination. Some background: Our system, which uses OP-TEE, has some "aggregated interrupts" that contain both secure and non-secure sources, for which we wanted to use SDEI to filter and dispatch to Linux (and SDEI requires EHF). Thanks! -Brian

Console getc() callback

by Sandrine Bailleux

Hi everyone, As you may know, console drivers in TF-A are required to provide a number of callbacks. One of them is getc() (to read a character from the console). Even though most platform ports provide a valid implementation of it, it does not seem to be called anywhere in the code base today, effectively qualifying it as dead code. I did a bit of git history digging and from what I've seen, the very first public version of TF-A (v0.2!) already had a getc() callback in the Arm PL011 UART driver. So my guess is that all subsequent UART drivers added after that followed the same approach. When the multi-console framework was introduced, it naturally catered for this feature as well. However, taking a step back, I wonder why we introduced getc() in the first place... Unlike other firmwares (like U-boot or EDK2), TF-A does not implement any kind of interactive user shell. And from a security point of view, getc() constitutes an attack vector into TF-A, which might allow an attacker to inject arbitrary data. So keeping this functionality without any valid use case sounds like a bad idea to me. Now, even though getc() is not used in upstream TF-A code right now, I realize there might be downstream / internal test setups which need it. For example, for firmware recovery purposes (receiving a backup firmware over a serial interface) or automated tests setups (some script driving a test session using some communication protocol over a serial interface). Is anyone depending on such use cases? If not, then I suggest we consider removing getc() feature altogether. We could always bring it back when there is a real use case for it (it will survive through git history). At the very least, I would like to disable getc() by default. Enabling it would require setting a build flag. Any thoughts or concerns? Best regards, Sandrine

Convert fiptool to Python script

by Varun Wadekar

Hello, We use fiptool extensively to generate the FIP blobs for NVIDIA platforms. But, we encountered the following issues during deployment. 1. fiptool has a dependency on the host machine for OpenSSL and gcc. 2. fiptool resides under the TF-A repo and is used by Hafnium and SPs. This creates a cross-repository dependency. As a workaround, we ship a prebuilt fiptool. But, due to OS dependency, this approach is not scalable across OS versions. E.g. One OS distribution might be using a lower OpenSSL version compared another, creating an incompatibility. I was thinking if converting fiptool to a python script might help resolve these issues. Sptool was converted into a Python script, so was wondering if anyone has tried converting fiptool to a Python script too. -Varun

Re: Workaround for ARM Cortex-A78AE Erratum 1941500 is not enabled

by Matthias Rosenfelder

Hi, the code is still incorrect after half a year. It has been changed twice, without fixing it. There was no response to the report I created [1]. If there is no interest / lack of response I may get the impression that my contributions are not welcomed at TF-A. Thus, I decided to not report any issues in the future. Sadly, this is how the open source idea dies - at least for this project.

SME support in RMM

by Arunachalam Ganapathy

Hi All, Please review the patch-set that adds the functionality in RMM to manage Scalable Matrix Extension (SME) context. If the CPU supports SME and if Realm accesses FPU/SVE functionality then NS SME state is saved to allow Realm to use FPU/SVE register state. https://review.trustedfirmware.org/q/topic:%22rmm_sme%22+(status:open%20OR%… Brief summary of changes made in different components: RMM: - Introduces SIMD context and exports APIs to the runtime component of RMM to initialize, save, restore, and switch SIMD context. - Adds SME support in RMM to manage NS SME context. Supports SVE+SME config and SME only config. - Handles SVE hint bit passed in RMI SMCs - Handles SME exceptions from Realms https://review.trustedfirmware.org/q/topic:%22rmm_sme%22+(status:open%20OR%… TF-A: - Enables FEAT_SME for RMM - Passes SMCCCv1.3 SVE hint bit in SMC function ID to RMM tf-a-tests: - There are changes in common lib routines for sve, sme so that testcases running in NS-EL2, S-EL1, R-EL1 can use these helper routines. - Adds helper routines to read, write, compare FPU and SVE Z, P, FFR registers - Adds SMCCCv1.3 SVE hint bit support in TFTF framework - Enables SME/SME2 during arch init - Adds SME helper routines and extends SVE lib routines to support streaming SVE mode. https://review.trustedfirmware.org/q/topic:%22rmm_sme%22+(status:open%20OR%… Thanks, Arun

Console scope flags/ console switch state - understanding

by Michal Simek

Hi, I am looking at how console flags are used and setup. In porting guide I see Function : bl31_plat_runtime_setup() [optional] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ :: Argument : void Return : void The purpose of this function is allow the platform to perform any BL31 runtime setup just prior to BL31 exit during cold boot. The default weak implementation of this function will invoke ``console_switch_state()`` to switch console output to consoles marked for use in the ``runtime`` state. Some platform are calling it but some of them not (like our Xilinx one). Tegra has in tegra_pwr_domain_power_down_wfi() console_flush(); console_switch_state(0); which is what none other has. Should console_flush() be called by default all the time when console is switched and also disabled when system goes down? Why console_switch_state(CONSOLE_FLAG_RUNTIME) is not called from bl31_main() when before bl31_plat_runtime_setup() is called we have console_flush() already? The second part of this how console scope is setup. Implementation is clear and set. void console_set_scope(console_t *console, unsigned int scope) { assert(console != NULL); console->flags = (console->flags & ~CONSOLE_FLAG_SCOPE_MASK) | scope; } The commit cc5859ca19ff ("Multi-console: Deprecate the `finish_console_register` macro") when finish_console_register is called (DCC is exception here) is setting up CONSOLE_FLAG_BOOT and CONSOLE_FLAG_CRASH by default. And most of platforms is calling console registration with calling console_set_scope() where new flags are recorded BOOT only, BOOT/RUNTIME, RUNTIME only or BOOT/RUNTIME/CRASH. I would like to understand what should be the right behavior. Why are platforms removing CRASH flag after registration? (I see that a lot of platforms are having private plat_crash_console_init() but pretty much crash console is the same with regular console). Why runtime console is setup directly in bl31_early_platform_setup2 when guidance is saying that it should be done much later? Also commit 63c52d0071ef ("plat/common/crash_console_helpers.S: Fix MULTI_CONSOLE_API support") removed CONSOLE_FLAG_CRASH from plat_crash_console_init but only from 64bit version. In 32bit version there is still there. It suggest that any C code should be called. Do we really need CONSOLE_FLAG_CRASH? Thanks, Michal -- Michal Simek, Ing.

Plan for RME support in QEMU

by Jean-Philippe Brucker

Hello, QEMU 8.1 added support for FEAT_RME. It is experimental, enabled with '-cpu max,x-rme=on', and requires fixes that will be available in QEMU 8.2. I'm working on adding support to TF-A and TF-RMM. I just submitted some TF-A patches for review (topic qemu-rme) that enable the feature for the virt platform, and intend to send the necessary changes for TF-RMM within a week or so. Without RMM, the Test Realm Payload is included into the FIP for light testing. After the TF-A and TF-RMM changes, I'd like to add support for the SBSA platform as well, which should be a relatively small change once the common QEMU support is merged. Thanks, Jean --- Building TF-A for QEMU with RME support: make -j CROSS_COMPILE=aarch64-linux-gnu- PLAT=qemu DEBUG=1 RMM=path/to/rmm/build/Debug/rmm.img ENABLE_RME=1 BL33=path/to/QEMU_EFI.fd QEMU_USE_GIC_DRIVER=QEMU_GICV3 all fip dd if=tf-a/build/qemu/debug/bl1.bin of=flash.bin bs=4096 conv=notrunc dd if=tf-a//build/qemu/debug/fip.bin of=flash.bin seek=64 bs=4096 conv=notrunc Running QEMU, for example: qemu-system-aarch64 -cpu max,x-rme=on,sme=off -m 3G -smp 8 -M virt,gic-version=3,virtualization=on,secure=on,acpi=off -bios flash.bin -kernel linux/arch/arm64/boot/Image -initrd path/to/initrd -append console=ttyAMA0 -nographic ...

Questions about memory encryption in FVP & TF-A

by Chenxu Wang

Hi all, I find that the latest Arm A-profile manual (DDI0487_J_a) mention several registers/instructions related to memory encryption (e.g., MECID-related registers). So can I ask two questions about it? 1. Is the FVP (I use the Base RevC AEM) support Memory Encryption Context (MEC) and Memory Protection Engine (MPE)? They are critical to memory encryption. If no, do we have some solutions to simulate them and verify memory encryption? 2. Does current TF-A support managing MPE, or other hardware related to memory encryption? Besides that, one problem for curiosity (only related to FVP). 3. I find some PCI-E device can use hardware encryption (example, NVIDIA H100 GPU). Can we attach this device to FVP's PCI-E port? Assume it has already connected to my Host PC via PCI-E. Sincerely, WANG Chenxu

New TrustedFirmware Discord Server

by Don Harbin

Hi All, Note you may have received another instance of this note but when I attempted to send to all TF ML's simultaneously it seemed to fail, so sending to each one at a time. Sorry about that. :/ We've created a Discord Server for real time chats/sharing. This solution comes at no cost to the project, is set up with channels for each project, includes a #general channel, and supports direct 1-1 chats between members, all with the goal of improving collaboration between trustedfirmware.org developers. We encourage all to join! :) Instructions for joining can be found on the TF.org FAQ page <https://www.trustedfirmware.org/faq/>. See you all there and please don't hesitate to reach out if you have any questions! Don Harbin TrustedFirmware Community Manager don.harbin(a)linaro.org

External Abort and SError Handling with RAS enabled

by Bharat Bhushan

Hi All, SCR_EL3.EA define whether to route External Abort and SError Interrupt to EL3 or EL2/1. ATF have a compile time flag to HANDLE_EA_EL3_FIRST_NS to program SCR_EL3.EA. Below text from ATF documentation. - ``HANDLE_EA_EL3_FIRST_NS``: When set to ``1``, External Aborts and SError Interrupts, resulting from errors in NS world, will be always trapped in EL3 i.e. in BL31 at runtime. When set to ``0`` (default), these exceptions will be trapped in the current exception level (or in EL1 if the current exception level is EL0). Have question related to forwarding of these errors when External Abort and SError Interrupt are routed to EL3. In this case will ATF forward Asynchronous SError Interrupt to Linux via RAS? Thanks -Bharat

MISRA-C Violations for function like macros in Trusted Firmware-A(TFA) code

by nithing1999＠gmail.com

It is observed that functions like macros like NOTICE, WARN and assert are present in the Trusted Firmware-A code. MISRA-C standard treats these as violations. shall we take these as deviation? please suggest. TFA Guidelines recommends using logging macros. So can we make deviations or need to change the MACRO into function.

by Nithin G

Hello, It is observed that device tree functions are present under lib/libfdt/... in Trusted Firmware-A code, but this device tree are not present in symbol table and also if we remove this device tree functions in code, board was successfully booting. However, while doing Coverity build to fix MISRA-C violations getting violations from this device tree code. So, is it possible to leave those violations please suggest? And when it will be enabled, please suggest. Thanks & Regards Nithin G

Question about Secondary CPU boot with spintable

by 빈성욱

Hi I ported TF-A and OPTEE on multi-core SoC, and I checked that xtest passed on CPU0 without failure. However, I'm failing in secondary CPU boot, and I'd like to get some help. I'm using ARMv8, and I'm using spintable as CPU enable method (not using PSCI FW). TF-A is in EL3. What I did ... 1. I released secondary CPU reset from bl31_early_platform_setup2() during primary CPU cold booting - set secondary CPU's RVBAR to bl31_entrypoint - release secondary CPU reset 2. I implemeneted plat_secondary_cold_boot_setup(), which is spining until linux kernel updates cpu-release-addr. Once linux kernel updates cpu-release-addr, then it changes EL to EL1 and jumps to secondary_startup() in linux 3. But secondary core goes to panic. It seems to happen when linux invokes optee_probe() Should I initialize some contexts (e.g. optee ..)? If so, where should I implement the corresponding codes? I'm wondering if I'm missing something, and I'd like to get some advice Thanks, --Bin

About erratum in TF-A

by Ming Huang

Hi Boyan, Some questions about erratum in TF-A: 1 Why workaround's flag is 0? In my mind, all flag should be 1 because there is func to check cpu revisions, such as check_errata_2326639. 43438ad1a patch: +ERRATA_N2_2326639 ?=0 2 After e444763d6(shorten errata flag defines) patch, introduce CPU_FLAG_LIST, Is the workaround's flag change to 1? e444763d6 patch: -ERRATA_N2_2326639 ?=0 +CPU_FLAG_LIST += ERRATA_N2_2326639 Regards, Ming

The increasing size of BL31

by Okash Khawaja

Hi, Typically, BL31 runs in SRAM which tends to be limited. As we add support for newer architectural features e.g. CCA, general features and standards, the size of BL31 image will grow and become harder to fit in most SRAMs. This email is to share ideas on how to address this problem. A simple approach will be to identify parts of NOBITS ELF sections of BL31 which can be moved out to DRAM. Since NOBITS sections aren't part of the file image, loading and authentication code doesn't have to change. The challenge will be to come up with some criteria to help decide what kind of buffers can be kept in DRAM vs SRAM. Other ideas are also welcome. Please share your thoughts. Thanks, Okash

Abandon inactive patches

by Manish Badarkhe

Hi All, It has happened in the past that developers have posted patches for review, but have been unable to respond to the comments on those patches for a long time and hence, maintainers pitched in and abandoned the patches in such cases. I created a patch [1] to make this official because the coding-review guidelines didn't mention it today. I would appreciate your help in reviewing this patch. Please let us know if you disagree about this approach. If you'd like, we can discuss this upcoming tech-forum. [1]: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/21848 Thanks, Manish Badarkhe

Re: EHF and SPMD G0 interrupt handling issues

by Olivier Deprez

Hi Varun, * for platforms with SPMD_SPM_AT_SEL2=1. These platforms already use EHF for servicing RAS interrupts today. Can you please have a look at https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/16047 ? and https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/16047/6/docs… The model, by the FF-A specification, is to permit G0 interrupts to trap to EL3 when NWd runs. A G0 interrupt is routed to a SP through the SPMD/SPMC by the use of EL3-SP direct messages: https://review.trustedfirmware.org/q/topic:%22el3_direct_msg%22+(status:ope… When SEL1/0 runs, G0 interrupts are first trapped to SEL2 and forwarded to EL3 by the FFA_EL3_INTR_HANDLE ABI. I appreciate the legacy capability to let G0 interrupts trap to EL3 while SWd runs is not possible/recommended with this design. This might indeed break earlier implementations; would it make sense aligning SW stacks to the latest of the FF-A spec recommendations? I let Raghu chime in if need be. Regards, Olivier. ________________________________ From: Varun Wadekar via TF-A <tf-a(a)lists.trustedfirmware.org> Sent: 06 June 2023 13:12 To: TF-A Mailing List <tf-a(a)lists.trustedfirmware.org> Subject: [TF-A] EHF and SPMD G0 interrupt handling issues Hi, We are in the process of upgrading the downstream TF-A to v2.9 for platforms with SPMD_SPM_AT_SEL2=1. These platforms already use EHF for servicing RAS interrupts today. I noticed that v2.9 has added G0 interrupt handling support to the SPMD. But I think the SPMD support still needs some work as it does not play nicely with EHF. I have found the following issues with the implementation. 1. SPMD and EHF both register handlers for G0 interrupts. But the interrupt management framework only allows one handler for INTR_TYPE_EL3. 2. The RAS framework still uses EHF and the SPMD interrupt handler breaks that functionality. 3. The SPMD handler calls into the platform which does not have any means to invoke the RAS interrupt handler. IMO, we should make SPMD a client of the EHF instead of creating yet another way for interrupt handling. For now, I register SPMD's G0 interrupt handler only if EL3_EXCEPTION_HANDLING=0, as a workaround. Thoughts?

EHF and SPMD G0 interrupt handling issues

by Varun Wadekar

Hi, We are in the process of upgrading the downstream TF-A to v2.9 for platforms with SPMD_SPM_AT_SEL2=1. These platforms already use EHF for servicing RAS interrupts today. I noticed that v2.9 has added G0 interrupt handling support to the SPMD. But I think the SPMD support still needs some work as it does not play nicely with EHF. I have found the following issues with the implementation. 1. SPMD and EHF both register handlers for G0 interrupts. But the interrupt management framework only allows one handler for INTR_TYPE_EL3. 2. The RAS framework still uses EHF and the SPMD interrupt handler breaks that functionality. 3. The SPMD handler calls into the platform which does not have any means to invoke the RAS interrupt handler. IMO, we should make SPMD a client of the EHF instead of creating yet another way for interrupt handling. For now, I register SPMD's G0 interrupt handler only if EL3_EXCEPTION_HANDLING=0, as a workaround. Thoughts?

[CI] New source files have been identified in your patch..

by Marcin Juszkiewicz

I am working on qemu_sbsa platform. We are now adding a way to share data from QEMU via TF-A to EDK2. Standard Arm way - using Secure Monitor Calls. I checked how other platforms do it and wrote a patch [1]. It got reviews, went through CI and all is fine except one thing: New source files have been identified in your patch.. plat/qemu/qemu_sbsa/sbsa_sip_svc.c 1. https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/20871 I have read TF-A documentation linked to CI report. This new file is covered already by PLAT=qemu_sbsa build because it is not optional. How to make CI pass? Same problem is with second patch [2] where I added another new source file. 2. https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/20953

TF-A v2.9 Release Schedule

by Joanna Farley

TF-A Community, This is to notify that we are planning to target the Trusted Firmware-A 2.9 release during the middle of May 2023 as part of the regular 6 month cadence. The aim is to consolidate all TF-A work since the 2.8 release. As part of this, a release candidate tag is targeted to be created and release activities commence from 10th May 2023 across all TF-A repositories. Essentially we will not merge any major enhancements from this date until the release is made. Please ensure any patches desired to make the 2.9 release are submitted in good time to be complete by 9th May 2023. Any major enhancement patches still open after that date will not be merged until after the release. This will involve the various repositories making up the broader TF-A project including the TF-A mainline, TF-A Tests, Hafnium, TF-A CI Scripts and TF-A CI Job. In addition a TF-RMM repository release will be made that is compatible with v2.9. We will endeavour minimise the disruption on patch merging and complete release activities ASAP after we start normally completing within 7-10 working days. Regards Joanna Farley

[RFC] Common API to retrieve pre-allocated share memory for Transfer List

by Raymond Mao

Hi, I am currently doing research to implement the Transfer List to comply with Arm's firmware handoff spec ( https://github.com/FirmwareHandoff/firmware_handoff) in order to have a standardized handoff approach between different firmware stages during boot. The idea is to create a Transfer List in BL2 and cache it into a pre-allocated memory in SRAM that can be shared between BL2 and BL3x. A prototype currently available is creating APIs under qemu platform code to retrieve the pre-defined memory address (The shared memory region is defined in platform_def.h). But I think we need to define a common API for this purpose to support all platforms. Please share your views or any suggestions. Thanks. Regards, Raymond

[RFC] Proposed location to host the firmware handoff specification.

by Jose Marinho

Hi, Arm worked to draft a firmware handoff [1] specification, evolving it based on community feedback. This activity followed the request of some members of the Arm ecosystem [2]. The spec (still at ALP – feedback/comments welcome!) standardizes how information is propagated between different firmware components during boot. The spec hopes to remove the reliance on bespoke/platform-specific information handoff mechanisms, thus reducing the code maintenance burden. The concept of entry types is present in the spec – these are data structure layouts that carry a specific type of data. New types are meant to be added, following the needs and use-cases of the different communities. Thus, these communities should be empowered to request new types! To enable community contributions, the specification must be hosted in a location that is friendly to change requests. We propose to host the spec in trustedfirmware.org (tf.org). Tf.org hosts several open-source projects and already has an open governance model. TF-A, and the associated community, rely on tf.org, and thus are already well equipped to maintain this specification and keep it up to date. Tf.org is agnostic of any downstream projects that would adopt this specification (e.g. U-boot, EDK2, etc.). We welcome the views of the communities and want to understand if there are any strong objections to what’s being proposed! If anyone has objections, we are happy to consider alternatives and associated trade-offs. Regards [1] https://developer.arm.com/documentation/den0135/latest [2] Re: [TF-A] Proposal: TF-A to adopt hand-off blocks (HOBs) for information passing between boot stages - TF-A - lists.trustedfirmware.org<https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.…>

Allow platforms to deny CPU power off request

by Varun Wadekar

Hello, We have a use case where we want to deny the CPU power off from a certain PE. The current lib/psci does not provide a way for a platform to do this. We have support to return an error from svc_off, but this does not cover the scenario where svc_off is NULL. There are multiple ways of handling this scenario. 1. Introduce a new platform function to check if CPU_OFF is allowed on the core 2. Return an error code from the pwr_domain_off() handler and unwind the CPU_OFF request 3. Something else. Any suggestions? -Varun

TF-A with TRUSTED_BOARD_BOOT failed when using mbedtls-3.4.0

by Chen-Yu Yang

Hi, I'm using TF-A 2.8 on mt7986 board, enable TRUSTED_BOARD_BOOT using mbedtls-3.4.0, TF-A BL2 hanged when loading BL31, it seems that BL2 failed to get correct oid in function get_ext(drivers/auth/mbedtls/mbedtls_x509_parser.c) after calling mbedtls_oid_get_numeric_string mbedtls_oid_get_numeric_string in 3.4.0 uses %c to print part of oid, (https://github.com/Mbed-TLS/mbedtls/blob/v3.4.0/library/oid.c#L864) but seems that ATF libc's snprintf doesn't support %c format, which causes mbedtls_oid_get_numeric_string to return incorrect oid oid_str dump in get_ext oid_str=%c.49.6.1.4.1.4128.2100.1 (mbedtls_oid_get_numeric_string) oid_str=1.3.6.1.4.1.4128.2100.1 (TRUSTED_FW_NVCOUNTER_OID) I try to change snprintf format %c to %u in mbedtls_oid_get_numeric_string, TF-A boots successfully Thanks

Re: Question about the Memory Encryption Engine on FVP

by Sandrine Bailleux

Hi, Concerning the following Fast Model Component: https://developer.arm.com/documentation/100964/1121/Fast-Models-components/… This component is already publicly documented although it is not integrated yet into the AEM FVP. The main usage is to identify software mis-programming, where the same Physical address is accessed through more than one Physical Address Space (PAS). As such, it is intended as a development / debugging tool only. If such a mis-programming scenario happened then the memory page corresponding to the accessed physical address would get corrupted. Notice memory encryption is not yet supported in TF-A's SW stacks. You won't find a reference for this feature in TF-A / TF-a-tests just now. Best regards, Sandrine

Is TF-A going to support MBEDTLS_AESCE_C option in mbedtls-3.4.0?

by Chen-Yu Yang

Hi, I'm working in TF-A 2.8 with mbedtls, I notice that mbedtls-3.4.0 starts to support AES crypto extension(MBEDTLS_AESCE_C) for some security reasons, I upgrade mbedtls from 2.28.0 to 3.4.0, and try to enable MBEDTLS_AESCE_C in TF-A. I fail to compile mbedtls aesce.c in TF-A build environment. I use CROSS_COMPILE=aarch64-gcc-7.5.0. It seems that AESCE needs some std libraries(e.g. arm_neon.h) supported by aarch64 gcc, while TF-A disables std libraries, and some compile flags(e.g. -mgeneral-regs-only) are conflict with current TF-A. I wonder is TF-A going to support MBEDTLS_AESCE_C option? Thanks

TF-A code documentation

by Michal Simek

Hi, I have talked to a couple of people to figure out what TF-A project is using for code documentation. Because I see at least in our platform that our documentation is somewhere between doxygen and kernel-doc but actually with a lot of mismatches. Sanbrine mentioned sending an email to the mailing list to start to have discussion about it. That's why I want to know the official code documentation format and how we should be checking that everything matches to make sure that documentation is not out of sync from code itself. When this is clear I will ask my team to fix all these issues. Thanks, Michal -- Michal Simek, Ing.

FEAT_SVE enablement in TF-A

by Jayanth Dodderi Chidanand

Hello all, We are sending this note to notify you of one of the breaking changes related to the enablement of FEAT_SVE in TF-A. This mainly impacts platforms which are configurable (FVP, QEMU, Total Compute). FEAT_SVE has now been moved under the Feature detection mechanism wherein a CPU feature macro can have 3 possible states * 0: FEAT_STATE_DISABLED * 1: FEAT_STATE_ALWAYS ( Always enabled, no runtime check) * 2: FEAT_STATE_CHECK (Dynamically check based on ID registers, done each time when feature registers are being accessed) For platforms which have a single configuration, it's better to choose either disabled or enabled (as it is a bit faster as there is no dynamic check). For platforms which can have different HW configurations, it makes sense to put them under FEAT_STATE_CHECK(=2), so that they will boot with any configuration of HW. Keeping this in mind, all configurable platforms (FVP, QEMU, TC) have been modified to adopt dynamic detection(FEAT_STATE_CHECK) for FEAT_SVE. [1] SVE Patch Reference: [1] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/20306 Best regards, Jayanth

rk3399 issue: no DMA in Linux with mainline TF-A and U-Boot SPL

by Christoph Fritz

Hello Kever, on a rk3399, booting current U-Boot SPL with mainline TF-A leads to missing DMA (and no sound) on Linux. However, when using rockchip its so called mini-loader (rk3399_miniloader_v1.26.bin) and their BL31 (rk3399_bl31_v1.35.elf) to boot, DMA works perfectly fine. Tested on a custom rk3399 board and on ROCK Pi4. Attached to this mail are two boot logs with some debug prints: - good_amba_log.txt (DMA works) - no_amba_log.txt (no DMA device) The main difference I can spot between the two logs is that on Linux (drivers/amba/bus.c) AMBA_CID (0xb105f00d) cannot be found. Instead, only some CORESIGHT_CIDs (presumably for debugging) and four 0x00000000 CIDs are detected. As a result, the "PL330 DMAC-241330" driver does not load. My theory is that DMA needs to be allowed somewhere in the undocumented syscon- registers, similar to what U-Boot is already doing for eMMC in arch_cpu_init() (arch/arm/mach-rockchip/rk3399/rk3399.c). Any ideas? Or maybe I'm just missing some configuration? Since multiple software projects are involved (TF-A, OP-TEE, U-Boot, Linux), I Cc'ed a bit. Thanks -- Christoph

Workaround for ARM Cortex-A78AE Erratum 1941500 is not enabled

by matthias.rosenfelder＠nio.io

Hi, according to the current erratum document for the ARM Cortex-A78AE [0], the workaround for erratum 1941500 says: "This erratum can be avoided by setting CPUECTLR_EL1[8] to 1." However, the current code on branch "master" (git hash 5906d97a832b6f6 ) at https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/lib/cpus/a… executes a "bic" instruction with an immediate, which is a synthetic instruction to clear the bit, instead of setting it. Moreover, the comment above says "Set bit 8 in ECTLR_EL1", which is inconsistent to the code. The equivalent workaround for the Cortex-A78 non-AE (erratum 1941498) uses the correct "orr" (bitwise-or) instruction to set the bit: https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/lib/cpus/a… Please confirm if this is an error. Thank you. Best Regards, Matthias [0] "Arm Cortex-A78AE (MP105) Software Developer Errata Notice", Document version: v14.0, Document ID: SDEN-1707912, https://developer.arm.com/documentation/SDEN1707912/latest

Question about configuring Juno R2 GPU SMMU in TF-A

by Chenxu Wang

Hi all, I try to enable the smmu of Juno R2 development board but face two great challenges. I am working on them and I still need some hints. Here are my problems: 1. By reading the SMMUv1 manuals I find that several registers are related to secure state (e.g., SMMU_sCR0). But in my TF-A and the latest version I can only find the SMMUv3 configurations, not SMMUv1/2. Thus, how to config these registers? Any reference? 2. For the non-secure GPU SMMU regs, I try to map and read them based on the Juno R2 manual. I know the GPU SMMU is a MMU-400, and its mmio is in 0x2b40_0000 - 0x2b40_ffff. Then in EL1 I first do ioremap(0x2b400000,0x10000) and then ioread32(). However I get the SError as "Bad mode in Error handler detected on CPU1, code 0xbf000002". I also try to do it in EL2 (with a hvc call and reading in the handler), but cannot get any valid number and still get SError when exiting EL2. But when I access the other smmus (e.g., a PCIe SMMU, in 0x2b50_0000), it works fine. Thus, is there something to prevent the Non-secure World from accessing the GPU SMMU MMIO? My source codes are downloaded from the arm-reference-platforms, in which Linux is v4.14.59 and TF-A is v2.1. Can someone help me? Sincerely, WANG Chenxu

Re: Post-boot loading of OP-TEE

by 梅建强(禹夜)

Hi, experts, I have another two other questions about this issue. (1) What should I do if the current optee to load already exists or I want to update optee? The most straightforward way I could think of is to reclaim the memory currently used by optee, then reload the optee image and initialize it. (2) optee may use multiple cores. When and how to process the initialization of multiple cores? Do you have any solutions or ideas?

This has previously been discussed in this mail thread [2] about half a year ago. Ultimately, it was concluded that this should in principle be accepted upstream as a platform choice to allow this or not. There are concerns that what we have in upstream TF-A should serve as good examples, and trusting the normal world to verify secure world software might not meet that criterion. There are also concerns about adding signature verification to BL31 Leaving the secure world wide open until the Linux kernel has been able to successfully load and verify an OP-TEE binary seems very risky. Even if it's claimed that the normal world can be trusted at this point, we're still giving up a critical level of defense without a good reason. I've started to review [1], but it should not be accepted for merging without support and approval from other maintainers. I would like to explore other options in this mail thread. In [2] it was suggested that a remnant of bl2 could be kept to verify OP-TEE before starting to execute it. This could be taken one step further and load a limited OP-TEE at boot which later is updated live, almost like what's discussed in [3]. This should minimize the impact on TF-A and also leave OP-TEE in charge of accepting an update instead of a divided responsibility between the normal world and TF-A.

Re: Post-boot loading of OP-TEE

by 梅建强(禹夜)

Hi, experts, If I want to apply the code to the S-EL2 framework (Hafnium as SPMC), What special processing should be added to spmd_handle_smc_load function or other function, such as context restore and save? I'm not clear about the details of the process, can you give me some help? Regards, Yuye. ------------------------------------------------------------------ 发件人：Jens Wiklander <jens.wiklander(a)linaro.org> 发送时间：2023年1月9日(星期一) 15:39 收件人：tf-a <tf-a(a)lists.trustedfirmware.org>; OP-TEE TrustedFirmware <op-tee(a)lists.trustedfirmware.org> 抄　送：Dan Handley <Dan.Handley(a)arm.com>; Jeffrey Kardatzke <jkardatzke(a)google.com>; jwerner <jwerner(a)chromium.org>; raghu.ncstate <raghu.ncstate(a)icloud.com>; Ilias Apalodimas <ilias.apalodimas(a)linaro.org> 主　题：Post-boot loading of OP-TEE Hi, The recent patch [1] for the OP-TEE Dispatcher in TF-A proposes a way of post-boot loading OP-TEE by the Linux kernel with signature verification in the normal world only. This has previously been discussed in this mail thread [2] about half a year ago. Ultimately, it was concluded that this should in principle be accepted upstream as a platform choice to allow this or not. There are concerns that what we have in upstream TF-A should serve as good examples, and trusting the normal world to verify secure world software might not meet that criterion. There are also concerns about adding signature verification to BL31 Leaving the secure world wide open until the Linux kernel has been able to successfully load and verify an OP-TEE binary seems very risky. Even if it's claimed that the normal world can be trusted at this point, we're still giving up a critical level of defense without a good reason. I've started to review [1], but it should not be accepted for merging without support and approval from other maintainers. I would like to explore other options in this mail thread. In [2] it was suggested that a remnant of bl2 could be kept to verify OP-TEE before starting to execute it.

Errata framework proposal

by Boyan Karatotev

Hi all, As presented on this week's tech forum, I have recently been working on a framework to improve errata implementations, consolidate the disparate requirements around them, and make errata information available at runtime. This is related, but separate to the errata ABI which is being worked on by Sona. Patches are available for review [1] and feedback is welcome. This email is to host discussion around the proposal, especially things that came up during the tech forum. The team would like to merge this sometime in April, but the sooner it is accepted, the sooner we can start (and complete!) the migration.

About kdump hang issue in SDEI dispatch

by Ming Huang

Hi James & TF-A guys, When hest acpi table configure Hardware Error Notification type as Software Delegated Exception(0x0B) for RAS event, kernel RAS interacts with TF-A by SDEI mechanism. On the firmware first system, kernel was notified by TF-A sdei call. The calling flow like as below when fatal RAS error happens: TF-A notify kernel flow: sdei_dispatch_event() ehf_activate_priority() call sdei callback // callback registered by kerenl ehf_deactivate_priority() Kernel sdei callback: sdei_asm_handler() __sdei_handler() _sdei_handler() sdei_event_handler() ghes_sdei_critical_callback() ghes_in_nmi_queue_one_entry() /* if RAS error is fatal */ __ghes_panic() panic() If fatal RAS error occured, panic was called in sdei_asm_handle() without ehf_deactivate_priority executed, which lead interrupt masked. If interrupt masked, system would be halted in kdump flow like this: arm-smmu-v3 arm-smmu-v3.3.auto: allocated 65536 entries for cmdq arm-smmu-v3 arm-smmu-v3.3.auto: allocated 32768 entries for evtq arm-smmu-v3 arm-smmu-v3.3.auto: allocated 65536 entries for priq arm-smmu-v3 arm-smmu-v3.3.auto: SMMU currently enabled! Resetting... So interrupt should be restored before panic otherwise kdump will hang. In the process of sdei, a SDEI_EVENT_COMPLETE(or SDEI_EVENT_COMPLETE_AND_RESUME) call should be called before panic for a completed run of ehf_deactivate_priority(). The ehf_deactivate_priority() function restore pmr_el1 to original value(>0x80). The SDEI dispatch flow was broken if SDEI_EVENT_COMPLETE was not be called. This will bring about two issue: 1 Kdump will hang for firmware reporting fatal RAS event by SDEI; (as explain above) 2 For NMI scene，TF-A enable a secure timer, the PPI 29 will trigger periodically. Kernel register a callback for hard lockup. The below code will not be called when panic in kernel callback: TF-A, services/std_svc/sdei/sdei_intr_mgmt.c sdei_intr_handler(): /* * We reach here when client completes the event. * * If the cause of dispatch originally interrupted the Secure world, * resume Secure. * * No need to save the Non-secure context ahead of a world switch: the * Non-secure context was fully saved before dispatch, and has been * returned to its pre-dispatch state. */ if (sec_state == SECURE) restore_and_resume_secure_context(); /* * The event was dispatched after receiving SDEI interrupt. With * the event handling completed, EOI the corresponding * interrupt. */ if ((map->ev_num != SDEI_EVENT_0) && !is_map_bound(map)) { ERROR("Invalid SDEI mapping: ev=%u\n", map->ev_num); panic(); } plat_ic_end_of_interrupt(intr_raw); How to fix above issues? I think the root cause is that kernel broken the SDEI dispatch flow, so kernel should modify to fix these issues. Thanks, Ming

Need to activate MEASURE_BOOT on nxp ls1043 platform

by Benoit Sansoni

Hello, I am working on a board based on NXP LS1043 processor (arm64) with TPM2 on SPI interface. I have the following boot sequence : TF-A + UBOOT + YOCTO. I have a look on the code where the TF-A MEASURE_BOOT was implemented for the fvp arm platform using OPTEE fTPM. As far as I understood, the event log is implemented based on the TCG2 EFI PROTOCOL from commit : commit 3ee148d6439b69d326f8e6d2a4ce822604e0e64c Merge: 43f7d8879 4a135bc33 Author: joanna.farley <joanna.farley(a)arm.com> Date: Wed Jul 22 16:35:11 2020 +0000 Nevertheless, I am surprised because I did not find any TPM2 driver in the current TF-A code. I would like to know : 1. How to port what was done for the fvp platform to my platform ? 2. What is code hashed in the TFA to create the event log ? 3. Why are there no TPM2 routine in the TF-A to expend PCR ? Thanks in advance for your help Benoit

PSCI OS-initiated mode

by Wing Li

Hi, The PSCI specification defines two different power state coordination modes for CPU_SUSPEND that can be used to put a core or a group of cores into a low-power state. These modes are the platform-coordinated mode (default) and the OS-initiated mode (optional). OS-initiated mode is currently not supported by TF-A, while both modes are supported by the Linux Kernel. Requesting reviews for the patches [1] adding support for OS-initiated mode in TF-A and the corresponding tests in TF-A-Tests. Any feedback and comments are much appreciated. Thanks in advance!

by Maciej Sieczka

Hello, I'm a noob here, and I need help. I've just built flash-image.bin for my MACCHIATObin Single Shot as follows, but it fails to boot - as follows further below: - git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git - Clone the binaries-marvell and mv-ddr-marvell Git repos alongside the trusted-firmware-a, and check out revisions as recommeded in TF-A build instructions for Armada80x0 (https://trustedfirmware-a.readthedocs.io/en/latest/plat/marvell/armada/buil…). - export CROSS_COMPILE=/my/path/to/arm-gnu-toolchain/11.3.rel1-x86_64-aarch64-none-elf/bin/aarch64-none-elf- - Build u-boot.bin: - git clone https://source.denx.de/u-boot/u-boot.git alongside the binaries-marvell and mv-ddr-marvell repos. - cd u-boot - git checkout v2023.01 - the latest release. - make mvebu_mcbin-88f8040_defconfig - Change CONFIG_DEFAULT_DEVICE_TREE to "armada-8040-mcbin-singleshot" (inspired by this SolidRun doc: https://github.com/SolidRun/documentation/blob/bsp/8040/u-boot.md). - Add arch/arm/dts/armada-8040-mcbin-singleshot.dts. Can be obtained e.g. from the latest Marvell kernel sources (https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/marvell/). - make - Built fine. - Build TF-A: - cd ../trusted-firmware-a/ - git checkout v2.8.0 - the latest release, as per changelog (https://trustedfirmware-a.readthedocs.io/en/latest/change-log.html). - make PLAT=a80x0_mcbin MV_DDR_PATH=../mv-ddr-marvell SCP_BL2=../binaries-marvell/mrvl_scp_bl2.img BL33=../u-boot/u-boot.bin mrvl_flash - Built fine.

Is NS_BL1U necessary to do FWU ?

by Jun.Chen(陳奕昕)

Hi, In ARM TBBR, there is a requirement “R0100_TBBR_AFM_FLASHING” (The AP firmware must switch to the Non-Trusted world for executing the SoC firmware loader), But there is no requirement for secure boot as long as I finish chain if ROT verification. So, can I implement FWU in BL2 which is verified and load from BL1 (ROM)? For example, BL1(ROM) -> Load and verify BL2U with new image from SD to secure RAM -> execute BL2U in Secure RAM then write new image to NAND flash Best regards, Jun

Checking SIP Service Calls range

by Michal Simek

Hi, I have one question about SIP Service Calls range and it's range checking. Based on DEN0028E SIP Service Calls ranges are 0x82000000-0x8200FFFF SMC32: SiP Service Calls 0xC2000000-0xC200FFFF SMC64: SiP Service Calls That's the ranges which we are using for implementing SOC specific SMC handlers and I found that in past it was also added code which is out of this range. Specifically in Xilinx ZynqMP you can see code like this if (is_em_fid(smc_fid)) { return em_smc_handler(smc_fid, x1, x2, x3, x4, cookie, handle, flags); } where EM range is 0x820e0001- 0x820e0003 is out of our range which is assigned to us. But there is no failure at all that we are out of ranged in spec. Shouldn't this be enforced by core itself? That's why I just wanted to know your opinion about it. We will definitely implement better masking to find out that 0x00fe0000 are all zeros. But that bit 16 is based on DEN0028E related to smcccv1.3 which I think we are not supporting now that's why should be 0 too. But definitely some information about this bit should be useful.

Coding guidelines update: Discouraging usage of weak functions

by Sandrine Bailleux

Hi all, As you may know, the TF-A project historically used to make heavy use of weak functions. The code base has numerous examples of them. However, based on previous discussions, I think we have general consensus in the TF-A community that the disadvantages of weak functions outweigh their benefits and for this reason we should discourage introducing new ones. In practice, I think this policy is already enforced most of the time in code reviews but I've now posted a patch that makes it explicit in the project's coding guidelines and provide the rationale behind it. https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/19398 Note that TF-A maintainers would still be responsible for enforcing this policy, as the CI system won't flag that for them, mainly because I think there might be legitimate cases for weak functions in rare instances so we'd get some false positives from such checks. We (at Arm) have got plans to gradually convert existing weak functions to strongly-defined implementations across the code base but this will take time. Like I said, I don't expect this change to be too controversial but please raise any concerns you may have in this email thread or on Gerrit. Best regards, Sandrine

[LTS v2.8.0] RC0 tag has been created

by Varun Wadekar

Hello, As announced in the last Tech forum, the code freeze date for the LTS branch was Feb 3, 2023. We have now merged all the patches published on the wiki [1]. The branch is still locked, and all the CI test runs have now been completed. We are trying to root cause one test failure, though. The RC0 tag was created today, and we request platform owners test the branch [2] on their downstream platforms if they wish. We are still on track to release on Feb 10 and will publish more updates shortly. Thanks.

[TF-A]: Deprecating mbedtls-2.28 support for TF-A 3.0 release

by Govindraj Raja

Hi All, We are in the process of migrating from mbedtls-2.28 support to 3.3 support we plan to deprecate mbedtls-2.28 support for TF-A 3.0 Release but would retain support for both 2.28 and 3.3 for TF-A 2.9 lifetime. There is draft implementation available[1] for code review which cleanups and prepares for mbedtls-3.3 support but retaining backward compatibility for mbedtls-2.28. Please let us know if there any objections to deprecation of mbedtls-2.28 in TF-A 3.0. -- Thanks Govindraj [1]: https://review.trustedfirmware.org/q/topic:%2522mbedtls3.3_support%2522 <https://review.trustedfirmware.org/q/topic:%2522mbedtls3.3_support%2522>

Query BL31 version from NWd

by Varun Wadekar

Hi, Happy new year! For NVIDIA Tegra platforms, we need the capability to query the BL31 version (e.g. 2.7, 2.8, 2.8.x) from the NWd at runtime. I could not find an FID that returns this value. I propose we introduce a new runtime service in bl31 that returns the version_string to the NWd to support this requirement. Thoughts? -Varun

Post-boot loading of OP-TEE

by Jens Wiklander

Hi, The recent patch [1] for the OP-TEE Dispatcher in TF-A proposes a way of post-boot loading OP-TEE by the Linux kernel with signature verification in the normal world only. This has previously been discussed in this mail thread [2] about half a year ago. Ultimately, it was concluded that this should in principle be accepted upstream as a platform choice to allow this or not. There are concerns that what we have in upstream TF-A should serve as good examples, and trusting the normal world to verify secure world software might not meet that criterion. There are also concerns about adding signature verification to BL31 Leaving the secure world wide open until the Linux kernel has been able to successfully load and verify an OP-TEE binary seems very risky. Even if it's claimed that the normal world can be trusted at this point, we're still giving up a critical level of defense without a good reason. I've started to review [1], but it should not be accepted for merging without support and approval from other maintainers. I would like to explore other options in this mail thread. In [2] it was suggested that a remnant of bl2 could be kept to verify OP-TEE before starting to execute it. This could be taken one step further and load a limited OP-TEE at boot which later is updated live, almost like what's discussed in [3]. This should minimize the impact on TF-A and also leave OP-TEE in charge of accepting an update instead of a divided responsibility between the normal world and TF-A.

Runtime loading of SEL-1

by Jeffrey Kardatzke

Hello, I'm working on a project for ChromeOS where we would like to be able to load the BL32 payload (OpTee) for SEL-1 after the linux kernel has booted rather than during the usual BL32 stage. We would do this via an SMC we would add which would take the OpTee image from linux and then have EL3 load it and perform the init for SEL-1 at that time. The reasoning behind this is that it's much easier to update the rootfs than the FW on our devices, and we can still ensure the integrity of the OpTee image if we load it early enough after the kernel boots. The main questions I have are if there are any issues people would be aware of by loading it after linux boots rather than during the usual BL32 stage? And I would definitely want to upstream this work if it's something we can do. Thanks, Jeffrey Kardatzke Google, Inc.

Question about using rme for smmuv3

by Chenxu Wang

Hi all, I test the SMMUv3 on FVP_Base_RevC-2xAEMvA_11.20_15, and my TF-A is the branch "arm_cca_v0.3". When I boot my FVP, I set the following commands: -C pci.pci_smmuv3.mmu.SMMU_ROOT_IDR0=3 \ -C pci.pci_smmuv3.mmu.SMMU_ROOT_IIDR=0x43B \ -C pci.pci_smmuv3.mmu.root_register_page_offset=0x20000 \ -C cluster0.rme_support_level=2 \ -C cluster1.rme_support_level=2 \ Based on the FVP manual, the SMMU base is 0x2b40_0000, and I think the SMMU Root Control Page should be 0x2b42_0000. Thus, I add the mapping to this region in plat_arm_mmap[], as: MAP_REGION_FLAT(0x2b420000,(0x2b430000-0x2b420000),MT_MEMORY | MT_RW |MT_ROOT) Then I try to access the SMMU_ROOT_IDR0 register in TF-A. Based on the manual, its offset is 0x0, so I read 0x2b42_0000. However, it returns 0x0, which is not what I configured in the boot commands (I think it should be 0x3). Can someone tell me the reason for this? Sincerely, WANG Chenxu

Upcoming "Stricter ASN.1 certificate parsing" patches

by Sandrine Bailleux

Hello everyone, I'd like to draw your attention on the following patch stack (contribution from Demi Marie Obenour, thank you!): https://review.trustedfirmware.org/q/owner:demiobenour%2540gmail.com+is:open These patches refactor the X.509 certificate parser leveraged by the trusted boot implementation in TF-A, such that the parser more closely follows the X.509 format specification [1] and ASN.1/DER encoding rules [2]. In a nutshell, this means that the X.509 parser is now stricter. Some ill-formatted certificates which TF-A would have previously accepted are now rejected. All trusted boot tests in the TF-A OpenCI have passed with these patches but I realize that this does not cover all platforms and use cases. Thus, I'd like to allow time for all platform maintainers that wish it to conduct their own testing and report any issue they're seeing on the mailing list. If we don't hear anything by end of Wednesday (14/12), we'll merge the patches. Best regards, Sandrine [1] See RFC5280, https://datatracker.ietf.org/doc/html/rfc5280 [2] ITU-T X.690, https://www.itu.int/ITU-T/studygroups/com10/languages/X.690_1297.pdf

[PATCH 1/1] plat/qemu: Improve aarch32 build support

by Rebecca Cran

While aarch32 isn't currently supported on qemu, platform.mk for both qemu and qemu_sbsa contain bugs that cause the build to fail earlier than it otherwise should.

[PATCH] fix(console): fix crash on spin_unlock with cache disabled

by Baruch Siach

Current code skips load of spinlock address when cache is disabled. The following call to spin_unlock stores into the random location that x0 points to. Move spinlock address load earlier so that x0 is always valid on spin_unlock call. Change-Id: Iac640289725dce2518f2fed483d7d36ca748ffe8 Signed-off-by: Baruch Siach <baruch(a)tkos.co.il> --- I'm posting this patch here since I have found no way to upload to review.trustedfirmware.org. I logged in via github, but I can not add SSH keys ("New SSH Key" grayed out), and "GENERATE NEW PASSWORD" shows Error 500.

Supporting QEMU in OpenCI

by Harrison Mutai

Hello everyone, Following our recent release, I'm pleased to provide more details on recent developments in our CI for QEMU. Linaro’s continuous integration platform OpenCI supports running emulated tests on QEMU. The tests are kicked off on Jenkins and deployed through the Linaro Automation and Validation Architecture LAVA. The obvious benefit of this is it makes it relatively easy to test TF-A in CI without a complex hardware setup, much like we do with FVPs. For this reason, we have added scripts to our OpenCI scripts repository to enable running this form of automated tests on QEMU. The initial patches provide a set of end-to-end boot tests (TF-A -> Linux shell prompt) that are included in our daily job [1]. The long term plan is to use this and further QEMU tests to gate patch submission (CI +1, +2), however, this is will only happen when we have confidence in their stability. You can view a sample test run here [2]. You can also reproduce the test setup manually in OpenCI or locally. In OpenCI this is done by running the tf-a-builder job with `qemu-boot-tests` as the test group [3]. In your local setup, this is done with the following command line: ``` $ test_run=1 \ workspace=$(mktemp -d) \ nfs_volume="$workspace" tfa_downloads="https://downloads.trustedfirmware.org/tf-a" tf_root="/path/to/trusted-firmware-a/" \ tftf_root="/path/to/tf-a-tests/" \ test_groups="qemu-boot-tests/qemu-default:qemu-linux.rootfs-fip.uefi-virt" \ bash -x $ci_root/script/run_local_ci.sh ``` We highly encourage you to contribute to the QEMU CI scripts if you can! Whether that be helping extend the tests or providing enhancements. We are also looking for help maintaining this specific area and the infrastructure around it - if this of interest, please do reach out! Cheers! Harrison [1] https://ci.trustedfirmware.org/job/tf-a-main [2] https://tf.validation.linaro.org/scheduler/job/1168495 [3] https://ci.trustedfirmware.org/job/tf-a-builder/

Re: 回复： building secure boot tf-a images without ROTK controlled by SW build engineer

by Neely, Brian

Hello, Just following up on my question regarding HSMs (pasted below). Do any of the maintainers of cert_create have feedback on this? Thanks! -Brian Just a quick follow-up on this question of using an HSM (or in general, some form of Key Management Infrastructure) to sign TF-A images. U-Boot has support for this with its mkimage utility (see https://github.com/u-boot/u-boot/blob/master/doc/uImage.FIT/signature.txt#L5...). This appears to a custom engine in OpenSSL (and in this case, the pkcs11 engine). My questions are: 1. Does TF-A’s cert_create tool support using custom OpenSSL engines? 2. If so, is there a procedure for using this? 3. If not, is there a plan to add support for this in the roadmap somewhere? * Or, in general, is there a plan to add HSM support for TF-A image signing?

Minimal kernel/firmware on Rock64 (rk3328)

by Robert Meissner

Hello, i found TF a very interesting project, however I would like to get booted with a really minimal firmware/kernel. I have a Rock64 with RK3328 Rockchip which I am trying to boot from sdcard with following sources: https://gitlab.com/jahro_me/sos/-/tree/master/ I have tried to setup UART for the device as described in the manual https://opensource.rock-chips.com/images/9/97/Rockchip_RK3328TRM_V1.1-Part1… On page 13 it states, the BOOT_ROM, INT_RAM is located at 0xffff0000. I have used this adress in kernel_entry https://gitlab.com/jahro_me/sos/-/blob/master/boot.s and in the main section https://gitlab.com/jahro_me/sos/-/blob/master/link.lds However, I could not get the kernel booted. I am not sure, if I need to remap the memory and how to do it. I guess, i should enable it with SGRF_SOC_CON2. Could anyone please help out to get the output, "Hello, You Rock!"? Best regards, Bob

PSCI OS-initiated mode

by Wing Li

Hi, The PSCI specification defines two different power state coordination modes for CPU_SUSPEND that can be used to put a core or a group of cores into a low-power state. These modes are the platform-coordinated mode (default) and the OS-initiated mode (optional). OS-initiated mode is currently not supported by TF-A, while both modes are supported by the Linux Kernel. Requesting reviews for the patches [1] adding support for OS-initiated mode in TF-A and the corresponding tests in TF-A-Tests. Any feedback and comments are much appreciated. Thanks in advance!

Announcing TF-RMM v0.1.0

by Soby Mathew

Hi Everyone The TF-RMM team is pleased to announce the first public release of RMM implementation aligned to RMM Beta0 Specification [1] . The RMM is a software component that runs at Realm EL2 and forms part of a system which implements the Arm Confidential Compute Architecture (Arm CCA). The implementation can create Realm VMs in the Realm PAS and the Realm contents can be attested as specified in the RMM specification. The official trustedfirmware.org git repo can be found at : https://git.trustedfirmware.org/TF-RMM/tf-rmm.git/. There is also a github read-only mirror and can be found at https://github.com/TF-RMM/tf-rmm . Contributions will be accepted via TF-RMM gerrit at trustedfirmware.org : https://review.trustedfirmware.org/q/project:TF-RMM%252Ftf-rmm Please see the readme [2] and the getting started guide [3] to get started with RMM. We expect patches for supporting Realm Management Extension (RME) in linux kernel and related kvm-unit-tests to be available in the coming months. The patch to exercise Realm creation and execution via TF-A-Tests is in review at the moment [4] and the OOB instructions for the same can be found in TF-A RME documentation [5]. We expect these patches to be part of the upcoming TF-A v2.8 release. The mailing list for the project is tf-rmm(a)lists.trustedfirmware.org<mailto:tf-rmm@lists.trustedfirmware.org>. Looking forward to fruitful community engagement and successful deployment Arm CCA systems in future. Best Regards Soby Mathew PS : We hope to setup readthedocs documentation in the coming days, but till then , please bear with the github rendering of the rst documentation. [1] https://developer.arm.com/documentation/den0137/1-0bet0/?lang=en [2] https://github.com/TF-RMM/tf-rmm/blob/main/docs/readme.rst [3] https://github.com/TF-RMM/tf-rmm/blob/main/docs/getting_started/getting-sta… [4] https://review.trustedfirmware.org/c/TF-A/tf-a-tests/+/17221 [5] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/17610

V2.8 Release code freeze notification

by Joanna Farley

Hi all, As documented in the Release Cadence section of the TF-A documentation (https://trustedfirmware-a.readthedocs.io/en/latest/about/release-informatio…) the v2.8 release has an expected code freeze date of 3rd week of November 2022. That equates to the start of that week Monday 14th November which is one calendar month away from tomorrow when the rc0 tag will be applied. Closing out the release takes around 6-10 working days normally over the last few releases. We want to ensure that planned feature patches for the release are submitted in good time for the review process to conclude. Preparations for v2.8 release is already underway. Thanks Joanna

Conditional CMOs

by Okash Khawaja

Hi, When a core is in debug recovery mode its caches are not invalidated upon reset, so the L1 and L2 cache contents from before reset are observable after reset. Similarly, debug recovery mode of DynamIQ cluster ensures that contents of the shared L3 cache are also not invalidated upon transition to On mode. A common use case of booting cores in debug recovery mode is to boot with caches disabled and preserve the caches until a point where software can dump the caches and retrieve their contents. TF-A however unconditionally cleans and invalidates caches at multiple points during boot, e.g. in bl31_entrypoint when cleaning bss and .data sections. This will not only lose the cache content needed for debugging but will potentially corrupt memory as well, leading to bugs when booting in recovery mode. Can we make CMOs in lib/aarch64/cache_helpers.S conditional upon some platform hook to address above scenario? Happy to work on a patch if the idea of conditional CMOs makes sense. Thanks, Okash

Inconsistencies with PLAT_XLAT_TABLES_DYNAMIC

by Jeffrey Kardatzke

Hello, Is there a reason there are inconsistencies in the handling of PLAT_XLAT_TABLES_DYNAMIC? Specifically I'm referring to in some places it uses #ifdef logic: https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/lib/utils/… and then in others it's using #if: https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/include/li… Also in some places it uses add_define: https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/services/s… and in others it's explicitly adding the define (w/ or w/out a value) to the _FLAGS for an image. https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/plat/imx/i… https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/plat/arm/b… I wanted to make use of this config option and noticed it wasn't getting picked up even when it was set and was considering cleaning up the usage of it by adding it to make_helpers/defaults.mk and then changing all the #ifdef's for it to be #if's. Thanks, -- Jeffrey Kardatzke jkardatzke(a)google.com Google, Inc.

Re: 回复： building secure boot tf-a images without ROTK controlled by SW build engineer

by Neely, Brian

Hello, Just a quick follow-up on this question of using an HSM (or in general, some form of Key Management Infrastructure) to sign TF-A images. U-Boot has support for this with its mkimage utility (see https://github.com/u-boot/u-boot/blob/master/doc/uImage.FIT/signature.txt#L…). This appears to a custom engine in OpenSSL (and in this case, the pkcs11 engine). My questions are: 1. Does TF-A’s cert_create tool support using custom OpenSSL engines? 2. If so, is there a procedure for using this? 3. If not, is there a plan to add support for this in the roadmap somewhere? * Or, in general, is there a plan to add HSM support for TF-A image signing? Thanks, Brian

Debug RME feature on FVP_Base_RevC-2xAEMvA_11.19_14

by Ádám Tóth

Hello, I am about to debug RME feature with ARM DS on FVP_Base_RevC-2xAEMvA_11.19_14 platform. I am using the Trusted Firmware with RME extension based on this description https://trustedfirmware-a.readthedocs.io/en/latest/components/realm-managem… My observation is running plainly the model, everything looks ok, the VFP can run the SW without any problem. (I can see the consol windows with normal booting procedure) In case I would like to set up the ARM debugger in ARM DS, the simulation immediately stops after start with a popup window: "Unable to connect to device ARMAEM-a_MP_0 Error opening connection to device 16 Socket is closed(E_io_error) Socket is closed" Apparently my Debug settings are good: With the same settings I can run/debug the complete ARM Reference Solution (Linux, u-boot, TrustedFirmware) based on this description: https://gitlab.arm.com/arm-reference-solutions/arm-reference-solutions-docs… but if I add additional flags for FVP: (-C cluster0.rme_support_level=2 -C cluster1.rme_support_level=2) I still can run the model, but cannot debug so when I activate the RME feature the ARM debugger do the previously mentioned behavior (stops right after start) How can I workaround this? What is the most efficient way to debug FVP with RME support. Any help is welcome here. Bye, Adam

Platform issues with mitigations of powerdown errata

by Boyan Karatotev

Hello everyone, There is a type of errata on a few CPUs where if they initiate a power down request which gets denied then attempting to power down again can fail in a deadlock. In essence, after the PE's power down sequence which ends on a WFI, but before actual power down, there exists a small window where an external event can interrupt the power down and cause the PE to continue after the WFI. Attempting to power down again after that can result in a deadlock. Affected CPUs are the Neoverse N2, Makalu ELP (Cortex X3), and Cortex A710. The SDEN [1] suggests to set the chicken bit CPUACTLR2_EL1[36] before the power down sequence and to clear it after coming out of the WFI (on anything other than RESET). The mitigations [2] set the bit in the `core_pwr_dwn` of each CPU but never clear it. This is because in the generic TF-A code path the WFI ends up being called in an infinite loop with the only way to come out of it being RESET. Most platforms with custom `pwr_domain_pwr_down_wfi` end up in the same loop or unrelated hardware reset mechanisms that avoid the errata. However, a few platforms could continue running as normal without going through a hardware reset which would require special treatment. The four problematic platforms are: * amlogic gxl and g12a: they fake a reset by manually calling the reset entrypoint on their primary CPUs only. This will leave the chicken bit set after reset. * socionext uniphier: same as amlogic but on all CPUs. * nxp (common code): I hope I understand what the platform is trying to do but there are 2 paths that raise an eyebrow: `_psci_sys_pwrdn_wfi` which has a single non-looped wfi (which could return as above) and `_psci_cpu_off_wfi` which seems to accept waking up as normal behaviour. The former path is a simple fix but the latter is the same case as amlogic and socionext. Due to its complexity I have not proposed any modification on either path. Finally, nvidia tegra and renesas (common code) have acceptable behaviour as far as the errata are concerned, however, they end up in the wfi loop only after a panic sequence. Although not problematic, this stands out. For all six platforms above there are a few options on how to proceed, the preferred one being to bring them in line with what everyone else does. Alternatively, ignoring the errata would be ok if these platforms never intend to use these CPUs. It must be noted, however, that it appears to be a family of errata, and these may not be all CPUs affected. [1]: the wording is identical for all 3 cores. For Neoverse N2: https://developer.arm.com/documentation/SDEN1982442/latest/ [2]: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/17157/1 Regards, Boyan

security: BL2 at EL3 on v8a based system

by sandeep tripathy

Hi, With the RME feature BL2 has to run at EL3 instead of EL1_S. EL3 has a separate PAS not accessible to EL1_S. Is there any harm in choosing to run BL2 at EL3 instead of BL2 at S_EL1 even for non-RME(v8a) systems? Given that EL3 and EL1_S have access to the same PAS. I am trying to revisit the motivation to run BL2 at EL1_S. I see there was an old discussion at https://github.com/ARM-software/tf-issues/issues/445 The reasoning was not pointing to any issue in specific but a generic principle of less permissiveness. Thanks Sandeep

Re: security: BL2 at EL3 on v8a based system

by Tripathy, Sandeep

Hi Manish, >>The existing name is more suitable for configuration where the platform has BL1 in it and BL2 can run at EL3 instead of S-EL1. Well, that is a minor thing to take care. V9 implementation does that in a way. >>This configuration is currently not available in TF-A but having this flexibility is not a bad idea and it can be platform's choice. That's my answer! And the default choice costs some memory with probably no increase in security (V8). >>BL31 can mask the secure world. Cant be done reliably on V8 (with root world V9 or EL2_S there is potential to compartmentalize the secure services as PAS isolation is feasible) Ex: EL1S can always overwrite the BL31 Xlat tables and take control of the vectors and many other ways depending on the platform. It's the same PAS! Thanks Sandeep

[PATCH TF-A] fix(plat/rcar3): Fix RPC-IF device node name

by Geert Uytterhoeven

According to the Generic Names Recommendation in the Devicetree Specification Release v0.3, and the DT Bindings for the Renesas Reduced Pin Count Interface, the node name for a Renesas RPC-IF device should be "spi". The node name matters, as the node is enabled by passing a DT fragment from TF-A to subsequent software. Fix this by renaming the device nodes from "rpc" to "spi". Fixes: 12c75c8886a0ee69 ("feat(plat/rcar3): emit RPC status to DT fragment if RPC unlocked") Signed-off-by: Geert Uytterhoeven <geert+renesas(a)glider.be> --- Background: On Renesas R-Car Gen3 platforms, the SPI Multi I/O Bus Controllers (RPC-IF) provide access to HyperFlash or QSPI storage. On production systems, they are typically locked by the TF-A firmware, unless TF-A is built with RCAR_RPC_HYPERFLASH_LOCKED=0. When unlocked, TF-A communicates this to subsequent software by passing a DT fragment that sets the "status" property of the RPC-IF device node to "okay". Unfortunately there are several issues preventing this from working all the way to Linux: 1. TF-A (and U-Boot on the receiving side) uses a device node name that does not conform to the DT specification nor the DT bindings for RPC-IF, 2. While U-Boot receives the RPC-IF enablement from TF-A, it does not propagate it to Linux yet, 3. The DTS files that are part of Linux do not have RPC HyperFlash support yet. This patch takes care of the first issue in TF-A. The related patches for U-Boot are [1]. Patches to enable RPC-IF support in Linux are available at [2]. Thanks for your comments! [1] "[PATCH u-boot 0/3] renesas: Fix RPC-IF enablement" https://lore.kernel.org/r/cover.1648544792.git.geert+renesas@glider.be [2] "[PATCH 0/5] arm64: dts: renesas: rcar-gen3: Enable HyperFlash support" https://lore.kernel.org/r/cover.1648548339.git.geert+renesas@glider.be --- plat/renesas/rcar/bl2_plat_setup.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/plat/renesas/rcar/bl2_plat_setup.c b/plat/renesas/rcar/bl2_plat_setup.c index bbfa16927d6c2384..f85db8d650c6b1a5 100644 --- a/plat/renesas/rcar/bl2_plat_setup.c +++ b/plat/renesas/rcar/bl2_plat_setup.c @@ -574,7 +574,7 @@ static void bl2_add_rpc_node(void) goto err; } - node = ret = fdt_add_subnode(fdt, node, "rpc@ee200000"); + node = ret = fdt_add_subnode(fdt, node, "spi@ee200000"); if (ret < 0) { goto err; } -- 2.25.1

Adding Openssl3 build capability to TF-A

by Gyorgy Szing

Hi, As you may know, the build system was changed, and the tip of master depends on Openssl3. This version is quite new and is not available in many old (or not so old) but still supported operating systems. (Ubuntu 18.04 is an example.) I made a quick and dirty fix to allow building Opessl3 right from TF-A if the source is pre-fetched. You can find this change here: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/16800 For our downstream project this is a perfect solution as the same component introducing the new dependency carries the solution. Thus, my build environment is not becoming TF-A version specific. From TF-A point of view the situation is not so simple. The above patch extends TF-A with "build environment provisioning" responsibility. Before this patch TF-A assumed, all "common" dependencies are available in the build environment, and this patch changes that. Yes, some strongly TF-A specific components were owned and built by TF-A, but openssl is different. Thus, my modification is a "game changer" in some ways. A few things to consider: * Openssl becomes a special kind of TPIP which the project will need to manage (e.g. look for security risks, version updates, compatibility to different OSs and OS versions, etc...). * This is a system wide component. There is a risk of breaking something the build uses. Hidden things like a python module depending on openssl and now picking up an incompatible version. * This change might be considered as layer bleeding since it "melds" responsibilities of the TF-A project and the "owner of the build environment". IMHO this might be a significant difference from supply-chain security perspectives. There are alternatives which might be considered better: * making the build system and host side tooling (e.g. cert_tool) backwards compatible with openssl2 * hosting pre-built static binaries somewhere, which would simplify build environment updates As I mentioned above, this is a "good enough" fix for my use-case, but not sure if this is the right approach from TF-A perspectives. I am happy to tidy up this patch and push it trough the review, but the efforts needed to implement "other options" are beyond my capacity. I am looking for feedback both from TF-A maintainers and from "build environment owners". Thanks! /George Ps.: Apologies for not doing "my homework". I know there is a ticket somewhere in Phabricator and I did not invest the needed time to find it.

Finally, a TF-A LTS Proposal!

by Okash Khawaja

TL;DR: Attached is the TF-A LTS proposal doc. Please review and share your thoughts. Hello everyone, Long term support for TF-A has a long history. As a community we have flirted with it for a while, and like any flirtation, it started with gossip -- in our case, over mailing list [1] -- more than two years ago. Then Varun Wadekar did a wonderful tech forum presentation [2] which demonstrated interest in the topic and raised interesting questions about LTS. After some time, the affair lost headline status, only to be revived again [3], earlier this year. This time however, there is a formal proposal (no pun intended). After the mailing list discussion and feedback from TF-A tech forum [4], we have put together a draft which attempts to give a concrete idea about what the TF-A LTS will look like. Please spare some time to read through it and share your feedback. The plan is to put LTS into action this November. Cheers! Okash [1] https://lists.trustedfirmware.org/archives/search?mlist=tf-a%40lists.truste… [2] https://www.trustedfirmware.org/docs/TF-A-LTS.pdf [3] https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.… [4] https://www.trustedfirmware.org/docs/TForg_LTS_proposal.pdf

Issue with adding ssh key to review server

by sparlane＠gmail.com

Hi All, Sorry if this is the wrong list, I'm trying to submit a patch for tf-a and I'm currently unable to add an ssh key or generate an https password to use for authentication. Perhaps I am doing something wrong? I'm trying to use the settings here: https://review.trustedfirmware.org/settings/#HTTPCredentials to add an ssh key and I get the error message "Error 500 (Server Error): Internal server error Endpoint: /accounts/self/sshkeys" Any help is greatly appreciated. Thanks, Scott (sparlane)

How to trap aborts caused by TZASC?

by Chenxu Wang

Hi all, I want to test how to trap the aborts caused by TZASC. For example, when I use NS-EL1 (e.g., OS) to access a Secure region (configured in TZASC), it will generate an abort. But I am not sure how to trap it. I think it is an external abort, so I enable the SCR_EL3.EA=1 and write a handler. However I cannot trap it. Also, my other handlers in EL3 still do not report the abort. Thus, how can I trap a TZASC abort? If I want to route it into EL3 to handle, how can I do it? Sincerely, WANG Chenxu
