Hi All,
The next release of the Firmware-A bundle of projects tagged v2.10 has an expected code freeze date of Nov, 7th 2023.
Refer to the Release Cadence section from TF-A documentation (https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/docs/about…).
Closing out the release takes around 6-10 working days after the code freeze.
Preparations tasks for v2.10 release should start in coming month.
We want to ensure that planned feature patches for the release are submitted in good time for the review process to conclude. As a kind recommendation and a matter of sharing CI resources, please launch CI jobs with care e.g.:
-For simple platform, docs changes, or one liners, use Allow-CI+1 label (no need for a full Allow-CI+2 run).
-For large patch stacks use Allow-CI+2 at top of the patch stack (and if required few individual Allow+CI+1 in the middle of the patch stack).
-Carefully analyze results and fix the change if required, before launching new jobs on the same change.
-If after issuing a Allow-CI+1 or Allow-CI+2 label a Build start notice is not added as a gerrit comment on the patch right away please be patient as under heavy load CI jobs can be queued and in extreme conditions it can be over an hour before the Build start notice is issued. Issuing another Allow-CI+1 or Allow-CI+2 label will just result in an additional job being queued.
Thanks & Regards,
Olivier.
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?
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… .
Best Regards
Soby Mathew
