Hi all, I want to load a specific image in BL31. But when I call load_auth_image(). It says "in function `load_image': trusted-firmware-a/common/bl_common.c:87: undefined reference to `plat_get_image_source'" Also, the io_read, io_size and etc. are undefined reference. I find other BL files (bl1, bl2) will call the load_auth_image() in their main functions or sub-functions. If I want to implement it on BL31, what should I do? Should I modify the Makefile? Sincerely, Wang

Re: [TF-A] Invitation: TF-A Tech Forum @ Every 2 weeks from 16:00 to 17:00 on Thursday (BST) (tf-a@lists.trustedfirmware.org)

by Joanna Farley

Hi Everyone, this is the TF-A Tech Forum meeting agenda for this week. Thanks Joanna Subject: ‘Measured Boot Driver - refactor and Critical Data measurement design’ Presented by: Manish Badarkhe 1. A brief overview of Measured Boot driver refactoring done in TF-A Bootloader 2. Discuss a few gaps observed in the Measured Boot driver and patches up-streamed for it 3. Discuss the list of critical data observed in TF-A firmware and its measurement design From: linaro.org_havjv2figrh5egaiurb229pd8c(a)group.calendar.google.com When: 16:00 - 17:00 2 December 2021 Subject: [TF-A] Invitation: TF-A Tech Forum @ Every 2 weeks from 16:00 to 17:00 on Thursday (BST) (tf-a(a)lists.trustedfirmware.org) Regular bi weekly Trustedfirmware.org TF-A TechForum.

Re: [TF-A] Missing CPU workaround warning message

by Varun Wadekar

Hi Pali, My understanding of the errata reporting mechanism is that some erratas are always checked during CPU boot. If the corresponding MACRO (ERRATA_A53_*) is disabled, then the ERRATA_MISSING code is reported. I would be concerned if the CPU is affected by the errata. If the errata needs to be enabled, the fix would be to enable the ERRATA_A53_* from the platform makefile. Hope this helps. -Varun -----Original Message----- From: TF-A <tf-a-bounces(a)lists.trustedfirmware.org> On Behalf Of Pali Rohár via TF-A Sent: Wednesday, July 7, 2021 9:11 PM To: Olivier Deprez <Olivier.Deprez(a)arm.com>; Bipin Ravi <Bipin.Ravi(a)arm.com>; tf-a(a)lists.trustedfirmware.org Cc: Konstantin Porotchkin <kostap(a)marvell.com>; Marek Behún <marek.behun(a)nic.cz> Subject: Re: [TF-A] Missing CPU workaround warning message External email: Use caution opening links or attachments Hello!

Re: [TF-A] PSCI lock contention

by Varun Wadekar

<Adding TF-A mailing list to the discussion> Thanks, Soby. I agree that this needs to be re-evaluated for platforms. I think we should introduce an option to disable them, if required. We plan to try some more experiments and hopefully remove the locks at least for Tegra platforms. Looking forward to the elaborate answer. From: Soby Mathew <Soby.Mathew(a)arm.com> Sent: Tuesday, 2 November 2021 10:18 AM To: Varun Wadekar <vwadekar(a)nvidia.com>; Manish Pandey2 <Manish.Pandey2(a)arm.com>; Dan Handley <Dan.Handley(a)arm.com> Cc: Joanna Farley <Joanna.Farley(a)arm.com>; Matteo Carlini <Matteo.Carlini(a)arm.com> Subject: RE: PSCI lock contention External email: Use caution opening links or attachments Hi Varun, The short answer is that the locks are used to differentiate the last-CPU-to-suspend and similarly first-CPU-to-powerup at a given power domain level. Now, recent CPU features like DynamIQ means that we don't need to do this differentiation upto cluster level which TF-A hasn't optimized for yet AFAICS. I am happy to elaborate further , but could you please send the query to the TF-A mailing list as I would prefer this discussion to happen in the open if possible. Best Regards Soby Mathew From: Varun Wadekar <vwadekar(a)nvidia.com<mailto:vwadekar@nvidia.com>> Sent: 01 November 2021 20:14 To: Soby Mathew <Soby.Mathew(a)arm.com<mailto:Soby.Mathew@arm.com>>; Manish Pandey2 <Manish.Pandey2(a)arm.com<mailto:Manish.Pandey2@arm.com>>; Dan Handley <Dan.Handley(a)arm.com<mailto:Dan.Handley@arm.com>> Cc: Joanna Farley <Joanna.Farley(a)arm.com<mailto:Joanna.Farley@arm.com>>; Matteo Carlini <Matteo.Carlini(a)arm.com<mailto:Matteo.Carlini@arm.com>> Subject: PSCI lock contention Hi, We were trying performance benchmarking for CPU_SUSPEND on Tegra platforms. We take all CPU cores to CPU_SUSPEND and then wake them up with IPI - all at once and in serial order. From the numbers, we see that the CPUs powering up later take more time than the first one. We have narrowed the most time consumed to the PSCI locks - documented at docs/perf/psci-performance-juno.rst. Can you please help me understand why these locks were added? As a quick experiment we tried the same benchmarking *without* the locks and the firmware does not blow up, but I would like to understand the impact from the analysis on Juno (docs/perf/psci-performance-juno.rst) Happy to hop on a call to discuss further.

Re: [TF-A] Trusted Firmware-A v2.6 release activities in November

by Joanna Farley

TF-A Community, Just a reminder we are looking to freeze the tree for release activities starting Monday. Thanks Joanna From: TF-A <tf-a-bounces(a)lists.trustedfirmware.org> on behalf of Joanna Farley via TF-A <tf-a(a)lists.trustedfirmware.org> Reply to: Joanna Farley <Joanna.Farley(a)arm.com> Date: Monday, 1 November 2021 at 12:41 To: Joanna Farley via TF-A <tf-a(a)lists.trustedfirmware.org> Subject: [TF-A] Trusted Firmware-A v2.6 release activities in November TF-A Community, This is to notify that we are planning to target the Trusted Firmware-A 2.6 release during the fourth week of Nov 2021 as part of the regular 6 month cadence. The aim is to consolidate all TF-A work since the 2.5 release. As part of this, a release candidate tag will be created and release activities will commence from 15th November 2021 across all TF-A repositories. Essentially we will not merge any major enhancements from this date until the release is made. Please ensure any patches desired to make the 2.6 release are submitted in good time to be complete by 12th November 2021. Any major enhancement patches still open after that date will not be merged until after the release. This will involve the various repositories making up the broader TF-A project including the TF-A mainline, TF-A Tests, Hafnium, TF-A CI Scripts and TF-A CI Jobs. We will endeavour minimise the disruption on patch merging and complete release activities ASAP after we start. Thanks Joanna

FW: Two issues in Qemu port docs

by Joanna Farley

Forwarded on to TF-A Mail list. Seems postings from people with gmail.com email domains get automatically rejected, sorry Ramon not sure if that can be addressed. Joanna On 03/11/2021, 14:20, "Ramon Fried" <rfried.dev(a)gmail.com> wrote: Hi. I'm trying to run the example in TF-A documentation. I found two problems. First, the files: "tee-header_v2.bin, tee-pager_v2.bin, tee-pageable_v2.bin" are not provided as binary downloads, and instructions on how to get them are missing. turn's out you need to build optee, but this step is skipped if you choose to download the QEMU_EFI.fd from Linaro. Second, after following the instructions step by step resulted in the following error: qemu-system-aarch64 -nographic -machine virt,secure=on -cpu cortex-a57 -kernel Image -no-acpi -append 'console=ttyAMA0,38400 keep_bootcon' -initrd rootfs.cpio.gz -smp 2 -m 1024 -bios flash.bin -d unimp NOTICE: Booting Trusted Firmware NOTICE: BL1: v2.5(release):v2.5-60-g7737fdf0e NOTICE: BL1: Built : 13:12:39, Nov 3 2021 NOTICE: BL1: Booting BL2 NOTICE: BL2: v2.5(release):v2.5-60-g7737fdf0e NOTICE: BL2: Built : 13:12:42, Nov 3 2021 NOTICE: BL1: Booting BL31 NOTICE: BL31: v2.5(release):v2.5-60-g7737fdf0e NOTICE: BL31: Built : 13:12:45, Nov 3 2021 read access to unsupported AArch64 system register op0:3 op1:0 crn:12 crm:12 op2:4 This occurs on Qemu 5.0 and also 6.0 Thanks, Ramon.
