Hi All, Please review the patch-set that adds the functionality in RMM to manage Scalable Matrix Extension (SME) context. If the CPU supports SME and if Realm accesses FPU/SVE functionality then NS SME state is saved to allow Realm to use FPU/SVE register state. https://review.trustedfirmware.org/q/topic:%22rmm_sme%22+(status:open%20OR%… Brief summary of changes made in different components: RMM: - Introduces SIMD context and exports APIs to the runtime component of RMM to initialize, save, restore, and switch SIMD context. - Adds SME support in RMM to manage NS SME context. Supports SVE+SME config and SME only config. - Handles SVE hint bit passed in RMI SMCs - Handles SME exceptions from Realms https://review.trustedfirmware.org/q/topic:%22rmm_sme%22+(status:open%20OR%… TF-A: - Enables FEAT_SME for RMM - Passes SMCCCv1.3 SVE hint bit in SMC function ID to RMM tf-a-tests: - There are changes in common lib routines for sve, sme so that testcases running in NS-EL2, S-EL1, R-EL1 can use these helper routines. - Adds helper routines to read, write, compare FPU and SVE Z, P, FFR registers - Adds SMCCCv1.3 SVE hint bit support in TFTF framework - Enables SME/SME2 during arch init - Adds SME helper routines and extends SVE lib routines to support streaming SVE mode. https://review.trustedfirmware.org/q/topic:%22rmm_sme%22+(status:open%20OR%… Thanks, Arun

Breaking dependency between 'run-coverage' and 'run-unittests' build rules

by Javier Almansa Sobrino

Hello all, We currently have a patch under review [1] which will break the existing dependency between 'run-converage' and 'run-unittests' rules in the RMM build system. This means that once the patch is merged, 'run-coverage' will not build and run RMM unittests. If ran in isolation, it will generate an empty coverage report by default. This allows to get coverage analysis for especific tests rather than for all the unittests, which makes the process of writting unittests for new modules easier as we can have a picture of the current coverage for such modules without being tainted by the rest of the unittests. Please note that in order to run coverage analysis on the whole existing set of unittests (as done previously by 'run-coverage') we need to invoke 'run-unittests' before. The patch, which is currently open for discussion and review, includes instructions on how to run 'run-coverage' to get different types of analysis.

Plan for RME support in QEMU

by Jean-Philippe Brucker

Hello, QEMU 8.1 added support for FEAT_RME. It is experimental, enabled with '-cpu max,x-rme=on', and requires fixes that will be available in QEMU 8.2. I'm working on adding support to TF-A and TF-RMM. I just submitted some TF-A patches for review (topic qemu-rme) that enable the feature for the virt platform, and intend to send the necessary changes for TF-RMM within a week or so. Without RMM, the Test Realm Payload is included into the FIP for light testing. After the TF-A and TF-RMM changes, I'd like to add support for the SBSA platform as well, which should be a relatively small change once the common QEMU support is merged. Thanks, Jean --- Building TF-A for QEMU with RME support: make -j CROSS_COMPILE=aarch64-linux-gnu- PLAT=qemu DEBUG=1 RMM=path/to/rmm/build/Debug/rmm.img ENABLE_RME=1 BL33=path/to/QEMU_EFI.fd QEMU_USE_GIC_DRIVER=QEMU_GICV3 all fip dd if=tf-a/build/qemu/debug/bl1.bin of=flash.bin bs=4096 conv=notrunc dd if=tf-a//build/qemu/debug/fip.bin of=flash.bin seek=64 bs=4096 conv=notrunc Running QEMU, for example: qemu-system-aarch64 -cpu max,x-rme=on,sme=off -m 3G -smp 8 -M virt,gic-version=3,virtualization=on,secure=on,acpi=off -bios flash.bin -kernel linux/arch/arm64/boot/Image -initrd path/to/initrd -append console=ttyAMA0 -nographic ...

New TrustedFirmware Discord Server

by Don Harbin

Hi All, Note you may have received another instance of this note but when I attempted to send to all TF ML's simultaneously it seemed to fail, so sending to each one at a time. Sorry about that. :/ We've created a Discord Server for real time chats/sharing. This solution comes at no cost to the project, is set up with channels for each project, includes a #general channel, and supports direct 1-1 chats between members, all with the goal of improving collaboration between trustedfirmware.org developers. We encourage all to join! :) Instructions for joining can be found on the TF.org FAQ page <https://www.trustedfirmware.org/faq/>. See you all there and please don't hesitate to reach out if you have any questions! Don Harbin TrustedFirmware Community Manager don.harbin(a)linaro.org

Upcoming RMM EAC2 Alignment

by Soby Mathew

Hi Everyone, This is a heads up about a planned TF-RMM alignment to RMM EAC2 specification. The required changes have been merged to a branch : https://git.trustedfirmware.org/TF-RMM/tf-rmm.git/log/?h=topics/rmm-eac2 . Once the integration testing with kernel components have completed successfully, we expect to merge this branch back to `main` branch. The details about suitable kernel/kvmtool/kvm-unit-tests branches will be published later. The planned delivery timelines can be found github project plan in this link : https://github.com/orgs/TF-RMM/projects/2/views/1 Best Regards Soby Mathew
