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.

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
