Hello All, I am coming from the TF-m domain, and now I am struggling with TF-a as I am not a Linux expert. I am just looking for the interactions with TF-a, such as getting psa attestation token etc. How can I find example these interactions from NS World (Linux) or lower privilege Secure World Executions such as OP-TEE or OP-TEE TAs? I suppose there shall be drivers and APIs provided by TF-a? Thanks Max

Addition of mbedTLS as a submodule dependency to TF-A-Tests

by Soby Mathew

Hi Everyone, In order to facilitate development for Device Assignment tests for RME-DA, we have added MbedTLS repo as a submodule dependency to tf-a-tests. The merge commit can be found here : https://review.trustedfirmware.org/plugins/gitiles/TF-A/tf-a-tests/+/3e72cd… The patch is done in such a way that existing build of TF-A-Tests or Test run is not affected due to the additional dependency. Only tests which depend on MbedTLS will be affected in that they will either be skipped or fail at runtime due to the missing dependency. Also, the change allows to use the config `MBEDTLS_DIR` to point to a MbedTLS directory outside the tf-a-tests source tree. This aligns with the TF-A mechanism for MbedTLS dependancy in case the submodule mechanism is not preferred. We expect existing CI and testing infrastructure to be unaffected by this change. Please let us know if you have any comments. Best Regards Soby Mathew

Firmware-A v2.12 release code freeze notification

by Govindraj Raja

Hi All, The next release of the Firmware-A bundle of projects tagged v2.12 has an expected code freeze date of Nov, 8th 2024. Refer to the release cadence section from TF-A documentation (https://trustedfirmware-a.readthedocs.io/en/latest/about/release-informatio…). Closing out the release takes around 6-10 working days after the code freeze. v2.12 release preparation tasks start from now. We want to ensure that planned feature patches for the release are submitted in good time for the review process to conclude. As a kind recommendation and a matter of sharing CI resources, please launch CI jobs with care e.g.: -For simple platform, docs changes, or one liners, use Allow-CI+1 label (no need for a full Allow-CI+2 run). -For large patch stacks use Allow-CI+2 at top of the patch stack (and if required few individual Allow+CI+1 labels in the middle of the patch stack). -Carefully analyze results and fix the change if required, before launching new jobs on the same change. -If after issuing a Allow-CI+1 or Allow-CI+2 label a Build start notice is not added as a gerrit comment on the patch right away please be patient as under heavy load CI jobs can be queued and in extreme conditions it can be over an hour before the Build start notice is issued. Issuing another Allow-CI+1 or Allow-CI+2 label will just result in an additional job being queued. -- Thanks, Govindraj R

TF-A: Compilation issues for Rockchip platforms

by Quentin Schulz

Hi all, I've sent a few patches for fixing some compilation warnings or issues on Rockchip platforms [1][2][3][4][5] but I'm left with a few still... [1] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/33080 [2] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/33081 [3] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/33082 [4] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/33083 [5] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/33084 1) RK3588 symbol redefinition in assembly ======================================================================== commit fc3b98b2124c2b773322da0201e9ad7a697e6323 Author: Quentin Schulz <quentin.schulz(a)cherry.de> Date: Mon Oct 28 12:40:18 2024 +0100 fix(rk3588): pmu: fix assembly symbol redefinition Somehow cpus_pd_req_enter_wfi() gets called multiple times and clang isn't happy about redefining the same label multiple times (it is an inline function). An option could be to force the code to not be inlined (with __attribute__((noinline))) as removing the explicit inline still made the compiler inline the code. Recreate the while loop without a label to fix the clang build issue: plat/rockchip/rk3588/drivers/pmu/pmu.c:763:7: error: symbol 'wfi_loop' is already defined 763 | "wfi_loop:\n" | ^ <inline asm>:5:1: note: instantiated into assembly here 5 | wfi_loop: | ^ Signed-off-by: Quentin Schulz <quentin.schulz(a)cherry.de> Change-Id: Ie9f55135b2f95a78deb7cbb94f9a62d3ba61e808 diff --git a/plat/rockchip/rk3588/drivers/pmu/pmu.c b/plat/rockchip/rk3588/drivers/pmu/pmu.c index f693dbdf0..f05d3e58f 100644 --- a/plat/rockchip/rk3588/drivers/pmu/pmu.c +++ b/plat/rockchip/rk3588/drivers/pmu/pmu.c @@ -760,10 +760,10 @@ static inline void cpus_pd_req_enter_wfi(void) "mrs x0, S3_0_C15_C2_7\n" "orr x0, x0, #0x1\n" "msr S3_0_C15_C2_7, x0\n" - "wfi_loop:\n" + "ldr x0, .+4\n" "isb\n" "wfi\n" - "b wfi_loop\n"); + "br x0\n"); } static void nonboot_cpus_off(void) ========================================================================= This only happens for clang and I'm a bit confused as to why.

TF-A Tech Forum regular call

by Olivier Deprez

Dear TF-A ML members, As mentioned in https://www.trustedfirmware.org/meetings/tf-a-technical-forum/, trustedfirmware.org hosts regular technical calls on Thursdays. It mentions TF-A although in practise a number of Cortex-A projects beyond TF-A were discussed (refer to prior recordings on this page). Unfortunately this slot hasn't been very active recently. By this email I'm kindly emphasizing this forum is open to the community (and beyond trustedfirmware.org members) and you are welcome to propose topics. Presentations/slides are not strictly necessary, and we can also host informal discussions or session of questions. If you think of a topic, please reach to me and I'll be happy to accommodate. Thanks for your contributions in advance! Regards, Olivier.

How to configure TZC-400 in ATF?

by 钱非凡

I tried to add two new tzc regions in ATF's source code, and test the memory access in the new region. ```cpp #define ARM_TZC_REGIONS_DEF \ {ARM_AP_TZC_DRAM1_BASE, ARM_EL3_TZC_DRAM1_END + ARM_L1_GPT_SIZE, TZC_REGION_S_RDWR, 0}, \ {ARM_NS_DRAM1_BASE, 0xA0000000-1, ARM_TZC_NS_DRAM_S_ACCESS, PLAT_ARM_TZC_NS_DEV_ACCESS}, \ {0xA0000000, 0xB0000000-1, ARM_TZC_NS_DRAM_S_ACCESS, PLAT_ARM_TZC_NS_DEV_ACCESS}, \ {0xB0000000, 0xC0000000-1, ARM_TZC_NS_DRAM_S_ACCESS, PLAT_ARM_TZC_NS_DEV_ACCESS}, \ {0xC0000000, ARM_NS_DRAM1_END, ARM_TZC_NS_DRAM_S_ACCESS, PLAT_ARM_TZC_NS_DEV_ACCESS}, \ {ARM_DRAM2_BASE, ARM_DRAM2_END, ARM_TZC_NS_DRAM_S_ACCESS, PLAT_ARM_TZC_NS_DEV_ACCESS} ``` But FVP throws some warnings: ``` Info: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: common_reset starts Info: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: build config register value 0x3003f08 4 filters, 9 regions, address width 64 Info: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.flashloader0: FlashLoader: Loaded 3164 kB from file '/home/bea1e/functionality-prototype/build/../trusted-firmware-a/build/fvp/release/fip.bin' Info: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.secureflashloader: FlashLoader: Loaded 25 kB from file '/home/bea1e/functionality-prototype/build/../trusted-firmware-a/build/fvp/release/bl1.bin' Info: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: common_reset starts Info: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: build config register value 0x3003f08 4 filters, 9 regions, address width 64 Warning: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: attempt to write invalid address 220 In file: (unknown):0 In process: FVP_Base_RevC_2xAEMvA.thread_p_32 @ 5126760 ns Warning: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: attempt to write invalid address 224 In file: (unknown):0 In process: FVP_Base_RevC_2xAEMvA.thread_p_32 @ 5126760 ns Warning: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: attempt to write invalid address 228 In file: (unknown):0 In process: FVP_Base_RevC_2xAEMvA.thread_p_32 @ 5126760 ns Warning: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: attempt to write invalid address 22c In file: (unknown):0 In process: FVP_Base_RevC_2xAEMvA.thread_p_32 @ 5126760 ns Warning: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: attempt to write invalid address 230 In file: (unknown):0 In process: FVP_Base_RevC_2xAEMvA.thread_p_32 @ 5126760 ns Warning: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: attempt to write invalid address 234 In file: (unknown):0 In process: FVP_Base_RevC_2xAEMvA.thread_p_32 @ 5126760 ns Warning: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: attempt to write invalid address 240 In file: (unknown):0 In process: FVP_Base_RevC_2xAEMvA.thread_p_32 @ 5127800 ns Warning: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: attempt to write invalid address 244 In file: (unknown):0 In process: FVP_Base_RevC_2xAEMvA.thread_p_32 @ 5127800 ns Warning: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: attempt to write invalid address 248 In file: (unknown):0 In process: FVP_Base_RevC_2xAEMvA.thread_p_32 @ 5127800 ns Warning: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: attempt to write invalid address 24c In file: (unknown):0 In process: FVP_Base_RevC_2xAEMvA.thread_p_32 @ 5127800 ns Warning: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: attempt to write invalid address 250 In file: (unknown):0 In process: FVP_Base_RevC_2xAEMvA.thread_p_32 @ 5127800 ns Warning: FVP_Base_RevC_2xAEMvA: FVP_Base_RevC_2xAEMvA.bp.tzc_400: attempt to write invalid address 254 In file: (unknown):0 In process: FVP_Base_RevC_2xAEMvA.thread_p_32 @ 5127800 ns ``` It seems the configuration registers for the two new regions are invalid. But I dont know how to solve this problem. Here are the arguments of FVP: ``` -C bp.ve_sysregs.exit_on_shutdown=1 \ -C cache_state_modelled=0 \ -C pctl.startup=0.0.0.0 \ -C cluster0.NUM_CORES=4 \ -C cluster1.NUM_CORES=4 \ -C bp.secure_memory=1 \ -C bp.dram_size=8 \ -C bp.tzc_400.diagnostics=1 \ -C bp.secureflashloader.fname=$(TF_A_PATH)/build/fvp/$(TF_A_BUILD)/bl1.bin \ -C bp.flashloader0.fname=$(TF_A_PATH)/build/fvp/$(TF_A_BUILD)/fip.bin \ -C bp.virtioblockdevice.image_path=$(BOOT_IMG) ``` Should I add more arguments while booting FVP? Is there any other advice for me to test the TZASC configurations?

Kernel source for RAS error injection on neoverse reference design platform

by Nagal, Amit

Hi, I am referring to https://neoverse-reference-design.docs.arm.com/en/latest/features/ras/ras.h… for RAS error injection on neoverse reference design platform. I am referring to below steps : mount -t debugfs none /sys/kernel/debug # Step needed for Buildroot only echo 0x80020000 > /sys/kernel/debug/apei/einj/error_type echo 1 > /sys/kernel/debug/apei/einj/oem-einj/sel-firmware-first echo 1 > /sys/kernel/debug/apei/einj/oem-einj/sel-component echo 1 > /sys/kernel/debug/apei/einj/oem-einj/sel-error-type echo 1 > /sys/kernel/debug/apei/einj/error_inject I want to refer to kernel source driver which exposes attributes : sel-firmware-first , sel-component , sel-error-type. Also that driver must be doing the actual injections and registering sdei events with EL3 . can I be advised where to look in for kernel sources ? Regards Amit
