RMM Performance Optimization in Multi-NUMA Architecture

by wuweinan＠huawei.com

Hi, In a multi-NUMA architecture, the RMM firmware is loaded to a memory of a numa. When the confidential virtual machine triggers VM_Exit, inst cache miss exists in running of code of the RMM, and an instruction needs to be fetched from the DRAM to the instruction cache. If the vCPU and RMM firmware memory do not belong to the same NUMA node, the instruction fetch delay is longer and the performance is poorer. I would like to ask if there is an optimization plan for this problem?

Tech Forum : Discuss RME GPT block fusing

by Soby Mathew

Hi, We would like to propose the following topic for discussion at the Tech Forum tomorrow. * RME Granule Protection Table (GPT) block fusing The GPT L1 entries needs to be fused to avoid TLB shattering for RME enabled CPUs. We will talk about the different prototype approaches tried in TF-A (EL3 firmware) and issues with each approach. We have a patch in review in which implements the “brute force” fusing algorithm. We explain our reasoning for picking this approach and possible future enhancements which may resolve some of the issues anticipated. Also the fine- grained locking scheme implemented for GPT manipulation will also be discussed. The patch in review is here : https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/26674. For design details of the GPT Library, please refer here : https://trustedfirmware-a.readthedocs.io/en/latest/components/granule-prote… .

Realm Initial Measurement calculation

by Peter Sawicki

Hi, I wonder if there is or there is a plan to develop a dedicated tool that allows a realm developer to calculate Realm Initial Measurements (RIMs) for realms(?) As you know, the remote attestation mechanism requires a verifier to be provisioned with reference values. In this case, a realm verifier should have access to the initial reference measurement (RIM) of a realm that is intended to be run on a remote Arm CCA platform. The algorithm that measures the initial state of realms (RIM) is higly sensitive to the content of a realm memory and the order of RMI operations. This means that not only the content of populated realm memory matters but also the implementation of the host components (e.g. kvm, kvmtool/qemu). For example, in the reference implementation of https://gitlab.arm.com/linux-arm/kvmtool-cca, the layout of memory and the content of DTB highly depend on the provided options (DTB is generated in run-time). Unfortunatelly, the content of DTB also depends on the linking order of object files (the order of DTB generation is imposed by __attribute__((constructor)) that is used to register devices). This complicates development of a separate tool for caclulating RIM, as the tool would have to emulate all quirks of the kvmtool. One of the solution of retrieving Realm Initial Measurements seems to be running the whole firmware/software (e.g. kvmtool/Linux host/TF-RMM) stack on the FVP emulator and gathering the RIM directly from the TF-RMM. This would require a realm developer to have access to the whole firmware/software stack and the emulator of the CCA platform. This might not always be an option. The other solution would require the implementation of a dedicated tool. For instance, a sensible approach could be to extend the functionality of kvmtool, which can be run on an ordinary Linux machine. Is Arm going to develop a dedicated tool(-s) for calculating RIMs? What is the recommended way of retrieving/calculating RIMs for realms? Kind regards, Piotr

RMM Coverage report available on GitHub

by Javier Almansa Sobrino

Hello all, We have added a GitHub workflow to RMM which allows the former to build and run the unittests along with their corresponding coverage report and upload such report in .html format to GitHub. The workflow is automatically triggered when new pushes are done to the main branch. In order to access to the coverage report, you can either * click on the green check symbol next to the latest commit, from there to "details" on the "Coverage on unittests for RMM" action on the pop up window and once in the action page, click on "Summary" on the left side menu. The report will appear in the "Artifacts" section as a .zip file with the name "coverage-results" or * On the TF-RMM repo main page, click on "Actions" and then click on the "Coverage on unittests for RMM" action corresponding to the latest commit. You can then access to the report as explained on the previous bullet. Please keep in mind that reports older than 90 days will be automatically deleted.

SME support in RMM

by Arunachalam Ganapathy

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. Thanks, Javier [1]: https://review.trustedfirmware.org/c/TF-RMM/tf-rmm/+/23039 IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

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 ...

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.

TF-A v2.9 Release Schedule

by Joanna Farley

TF-A Community, This is to notify that we are planning to target the Trusted Firmware-A 2.9 release during the middle of May 2023 as part of the regular 6 month cadence. The aim is to consolidate all TF-A work since the 2.8 release. As part of this, a release candidate tag is targeted to be created and release activities commence from 10th May 2023 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 2.9 release are submitted in good time to be complete by 9th May 2023. 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 Job. In addition a TF-RMM repository release will be made that is compatible with v2.9. We will endeavour minimise the disruption on patch merging and complete release activities ASAP after we start normally completing within 7-10 working days. Regards Joanna Farley

Announcing the unit test framework for TF-RMM

by Javier Almansa Sobrino

Hello everyone, I would like to let you know that I have pushed a set of patches to add support for unit tests into TF-RMM. The patches are available for review at https://review.trustedfirmware.org/q/topic:%22utest-framework%22+(status:op… The unit test framework introduced on the patches sits on top of the fake-host platform, which allows to run the tests natively in the development host. The patches include: * A unit test framework based on CMake add_test() functionality. The framework incorporates a variant for the fake_host platform which builds and links the tests and allows them to be run automatically. * Unit tests for the slot buffers and granules APIs, both part of the realm library component (lib/realm) to be used as guideline for further unit tests. Currently under development are: * Support for coverage testing * Documentation for the unit test framework A TF-A Tech Forum Session will be announced at some point to present and discuss the feature more in detail. Best regards, Javier

Announcing TF-RMM v0.1.0

by Soby Mathew

Hi Everyone The TF-RMM team is pleased to announce the first public release of RMM implementation aligned to RMM Beta0 Specification [1] . The RMM is a software component that runs at Realm EL2 and forms part of a system which implements the Arm Confidential Compute Architecture (Arm CCA). The implementation can create Realm VMs in the Realm PAS and the Realm contents can be attested as specified in the RMM specification. The official trustedfirmware.org git repo can be found at : https://git.trustedfirmware.org/TF-RMM/tf-rmm.git/. There is also a github read-only mirror and can be found at https://github.com/TF-RMM/tf-rmm . Contributions will be accepted via TF-RMM gerrit at trustedfirmware.org : https://review.trustedfirmware.org/q/project:TF-RMM%252Ftf-rmm Please see the readme [2] and the getting started guide [3] to get started with RMM. We expect patches for supporting Realm Management Extension (RME) in linux kernel and related kvm-unit-tests to be available in the coming months. The patch to exercise Realm creation and execution via TF-A-Tests is in review at the moment [4] and the OOB instructions for the same can be found in TF-A RME documentation [5]. We expect these patches to be part of the upcoming TF-A v2.8 release. The mailing list for the project is tf-rmm(a)lists.trustedfirmware.org<mailto:tf-rmm@lists.trustedfirmware.org>.
