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!

u-boot image for MACCHIATObin Single Shot builds but won't boot

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>
