EHF and SPMD G0 interrupt handling issues

by Varun Wadekar

Hi, We are in the process of upgrading the downstream TF-A to v2.9 for platforms with SPMD_SPM_AT_SEL2=1. These platforms already use EHF for servicing RAS interrupts today. I noticed that v2.9 has added G0 interrupt handling support to the SPMD. But I think the SPMD support still needs some work as it does not play nicely with EHF. I have found the following issues with the implementation. 1. SPMD and EHF both register handlers for G0 interrupts. But the interrupt management framework only allows one handler for INTR_TYPE_EL3. 2. The RAS framework still uses EHF and the SPMD interrupt handler breaks that functionality. 3. The SPMD handler calls into the platform which does not have any means to invoke the RAS interrupt handler. IMO, we should make SPMD a client of the EHF instead of creating yet another way for interrupt handling. For now, I register SPMD's G0 interrupt handler only if EL3_EXCEPTION_HANDLING=0, as a workaround. Thoughts?

[CI] New source files have been identified in your patch..

by Marcin Juszkiewicz

I am working on qemu_sbsa platform. We are now adding a way to share data from QEMU via TF-A to EDK2. Standard Arm way - using Secure Monitor Calls. I checked how other platforms do it and wrote a patch [1]. It got reviews, went through CI and all is fine except one thing: New source files have been identified in your patch.. plat/qemu/qemu_sbsa/sbsa_sip_svc.c 1. https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/20871 I have read TF-A documentation linked to CI report. This new file is covered already by PLAT=qemu_sbsa build because it is not optional. How to make CI pass? Same problem is with second patch [2] where I added another new source file. 2. https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/20953

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
