Hi Everyone This is to notify that we have done a TF-RMM v0.3.0 release to correlate with TF-A v2.9 release [1]. The highlights of the release are: * Add support to create Realms which can make use of SVE, if present in hardware. * Refactor and improve the Stage 1 translation table library `lib/xlat` API to better fit RMM usage. * Add PMU support for Realms as described by RMM v1.0 Beta0 specification. * Support getting DRAM info from the Boot manifest dynamically at runtime. * RMM can now support the 2nd DDR bank on FVP * Define a unit test framework using CppUTest for RMM. * Add unit-tests for granule, slot-buffer and Stage 1 translation table `lib/xlat`. * Improvements to fake-host and unit tests framework. * Build improvements in RMM and bug fixes. Please find more details of the release in the changelog [2]. Best Regards Soby Mathew [1] https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tag/?h=v2.9.0 [2] https://tf-rmm.readthedocs.io/en/tf-rmm-v0.3.0/about/change-log.html#v0-3-0

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
