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

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?
