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

Changes needed on the FVP command line to enable FEAT_LPA2

by Javier Almansa Sobrino

Hi all, We are introducing support for FEAT_LPA2 into TF-RMM (patches are available here<https://review.trustedfirmware.org/q/topic:%22lpa2-support%22+(status:open%…>). Once the patches are merged, FEAT_LPA2 will be a mandatory feature for TF-RMM to work. This means that FVP will need to enable this feature when running. To do so, the following changes are needed on the command line: - -C cluster0.PA_SIZE=48 + -C cluster0.PA_SIZE=52 + -C cluster0.has_large_va=2 + -c cluster0.has_52bit_address_with_4k=2 This needs to be applied to all the clusters on the model. In addition to that, "arch_version" on the model needs to be set to "8.7" or higher. The changes can be applied at any point from now as at the moment TF-RMM is able to work with and without FEAT_LPA2. Once the patches are merged, though, TF-RMM will fail during boot if FEAT_LPA2 is not available. Thank you very much.
