Questions about Hafnium as S-EL2

by Junho Choi

Hello, I'm Junho Choi in Samsung S.LSI and I've been working on virtualization solution. I have some questions about Hafnium for Secure EL2 extension. (1) Why do you consider VHE as default option? (I saw it in arch_mm_init) According to Hafnium init sequence, has_vhe_support always returns true as long as ARM cores have support for VHE. Is there any requirements that Hafnium should support VHE? (2) TF-A's SPMD has only forwarded svc_on_finish and svc_off of PSCI. Why doesn't SPMD forward other commands such as CPU_SUSPEND? In case of the CPU_SUSPEND, secure EL2 or SP may need to know when physcial CPU turns off. (3) Why do you set HCR_EL2.VI and VF to handle virtual interrupt? I think we have an another method to use List registers (ICH_LRn_EL2) to inject virtual interrup to guest (SP). I'm not sure whether asking you is proper or not. If you're not the right person, please forward this mail to the right person. Thanks!

Firmware-A v2.12 release code freeze notification

by Govindraj Raja

Hi All, The next release of the Firmware-A bundle of projects tagged v2.12 has an expected code freeze date of Nov, 8th 2024. Refer to the release cadence section from TF-A documentation (https://trustedfirmware-a.readthedocs.io/en/latest/about/release-informatio…). Closing out the release takes around 6-10 working days after the code freeze. v2.12 release preparation tasks start from now. 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 labels 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, Govindraj R
