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

MISRA-C violation for unused functions in Trusted Firmware-A(TFA) code

by nithing1999＠gmail.com

It is observed that several unused functions are present in Trusted Firmware-A code, is it possible to mask those unused functions or leave them as it is to fix MISRA-C Violations? If these functions are not appearing in symbol table, then no need to take actions on violations reported in these functions? Please suggest.

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.

MISRA-C violation for Device Tree (FDT) in Trusted Firmware-A (TFA) code.

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

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

Re: New Defects reported by Coverity Scan for ARM-software/arm-trusted-firmware

by Sandrine Bailleux

Hi Manish, I'll answer on behalf of Benjamin and Sieu because I think they are offline now. I reached out to these guys privately this morning and they said they will post patches to fix these defects. Cheers, Sandrine

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
