PSCI patches fail TF-A-tests on 2 platform configs

by Yann Gautier

Hi, Patrick has sent 2 correction patches for PSCI stack in OSI mode there: https://review.trustedfirmware.org/q/topic:%22fix_psci_osi%22 But when running CI+2, there are 2 platforms for which 2 PSCI OSI tests are failing: fvp-ext-pstate-ea-el3|fvp-default|fvp-tftf-fip.tftf-cortexa57x4a53x4-debug fvp-ext-pstate-ea-el3|fvp-default|fvp-tftf-fip.tftf-aemv8a-debug I'm not familiar with those test configs, but when checking lava logs, I see those traces for failing tests: 2024-01-11T14:21:59 > Executing 'CPU suspend to powerdown at level 1 in OSI mode' 2024-01-11T14:21:59 INFO: Booting

Maybe there is something wrong with the TF-A patches? Or the platforms tests or configs need to be updated? If you have any clue that would be very helpful! Thanks, Yann

Cache Maintenance For SiP buffers

by Ahmad Fatoum

Hi, I was looking at imx_hab_handler, which forwards calls into the BootROM on i.MX SoCs in response to secure monitor calls. The BootROM call (and thus the SiP call) accepts two pointers as arguments, where it writes data. The plat/imx/imx8m/imx8m*/imx8m*_bl31_setup.c files map the RAM as MT_MEMORY | MT_RW, which would mean that not only is it writable from TF-A side, but it's also mapped cacheable. I see no explicit cache maintenance in the i.MX SiP code for these two pointer arguments and haven't been successful to find where in TF-A core code if at all, complete D-Cache is flushed on SMC exit. Therefore I ask: - Don't shared non-secure memory buffers between EL3 and lower EL require explicit cache maintenance? - Did I miss the place where this cache maintenance is done? - How did it work so far? barebox does explicit flushing before HAB SiP, invalidation after. U-Boot doesn't do cache maintenance. Both apparently work...

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
