Hello TF-A Community, The meeting invite this week has been updated with an agenda. In case you have not seen this the details are: The TF-RMM component was published last week and was announced in this mailing list: https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.… This week Javier Almansa Sobrino of the TF-RMM team would like to present on the TF-RMM Unit test framework The TF-RMM Unit test framework allows the exercising and validation of the software components of TF-RMM to be performed natively on the development host, making the development of new features, as well as the debugging of existing ones, easier. This talk will introduce this framework as well as the fake_host architecture for TF-RMM which allows the building and running of TF-RMM natively on the development host. We will also discuss how to implement unit tests for different components and we will introduce some features such as code coverage test for TF-RMM. Thanks Joanna Meeting details are: Join Zoom Meeting https://armltd.zoom.us/j/97858987231?pwd=U3NxdEk2YjI0OS90NzE1WEdHWE10Zz09&f… Meeting ID: 978 5898 7231 Passcode: 472153 One tap mobile +16465189805,,97858987231#,,,,*472153# US (New York) +13462487799,,97858987231#,,,,*472153# US (Houston) Dial by your location +1 646 518 9805 US (New York) +1 346 248 7799 US (Houston) +1 408 638 0968 US (San Jose) Meeting ID: 978 5898 7231 Passcode: 472153 Find your local number: https://armltd.zoom.us/u/adRXFKP35m Join by SIP 97858987231(a)zoomcrc.com Join by H.323 162.255.37.11 (US West) 162.255.36.11 (US East) 115.114.131.7 (India Mumbai) 115.114.115.7 (India Hyderabad) 213.19.144.110 (Amsterdam Netherlands) 213.244.140.110 (Germany) 103.122.166.55 (Australia Sydney) 103.122.167.55 (Australia Melbourne) 209.9.211.110 (Hong Kong SAR) 149.137.40.110 (Singapore) 64.211.144.160 (Brazil) 69.174.57.160 (Canada Toronto) 65.39.152.160 (Canada Vancouver) 207.226.132.110 (Japan Tokyo) 149.137.24.110 (Japan Osaka) Meeting ID: 978 5898 7231 Passcode: 472153

Minimal kernel/firmware on Rock64 (rk3328)

by Robert Meissner

Hello, i found TF a very interesting project, however I would like to get booted with a really minimal firmware/kernel. I have a Rock64 with RK3328 Rockchip which I am trying to boot from sdcard with following sources: https://gitlab.com/jahro_me/sos/-/tree/master/ I have tried to setup UART for the device as described in the manual https://opensource.rock-chips.com/images/9/97/Rockchip_RK3328TRM_V1.1-Part1… On page 13 it states, the BOOT_ROM, INT_RAM is located at 0xffff0000. I have used this adress in kernel_entry https://gitlab.com/jahro_me/sos/-/blob/master/boot.s and in the main section https://gitlab.com/jahro_me/sos/-/blob/master/link.lds However, I could not get the kernel booted. I am not sure, if I need to remap the memory and how to do it. I guess, i should enable it with SGRF_SOC_CON2. Could anyone please help out to get the output, "Hello, You Rock!"? Best regards, Bob

Support for SVE + FP in TF-A

by Okash Khawaja

Hi, Currently TF-A doesn't support enabling both SVE and FP for both worlds. What can we do to support both SVE and FP in either world? Thanks, Okash

PSCI OS-initiated mode

by Wing Li

Hi, The PSCI specification defines two different power state coordination modes for CPU_SUSPEND that can be used to put a core or a group of cores into a low-power state. These modes are the platform-coordinated mode (default) and the OS-initiated mode (optional). OS-initiated mode is currently not supported by TF-A, while both modes are supported by the Linux Kernel. Requesting reviews for the patches [1] adding support for OS-initiated mode in TF-A and the corresponding tests in TF-A-Tests. Any feedback and comments are much appreciated. Thanks in advance! Wing [1] https://review.trustedfirmware.org/q/topic:psci-osi

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>. Looking forward to fruitful community engagement and successful deployment Arm CCA systems in future. Best Regards Soby Mathew PS : We hope to setup readthedocs documentation in the coming days, but till then , please bear with the github rendering of the rst documentation.

V2.8 Release code freeze notification

by Joanna Farley

Hi all, As documented in the Release Cadence section of the TF-A documentation (https://trustedfirmware-a.readthedocs.io/en/latest/about/release-informatio…) the v2.8 release has an expected code freeze date of 3rd week of November 2022. That equates to the start of that week Monday 14th November which is one calendar month away from tomorrow when the rc0 tag will be applied. Closing out the release takes around 6-10 working days normally over the last few releases. We want to ensure that planned feature patches for the release are submitted in good time for the review process to conclude. Preparations for v2.8 release is already underway. Thanks Joanna
