Abandon inactive patches

by Manish Badarkhe

Hi All, It has happened in the past that developers have posted patches for review, but have been unable to respond to the comments on those patches for a long time and hence, maintainers pitched in and abandoned the patches in such cases. I created a patch [1] to make this official because the coding-review guidelines didn't mention it today. I would appreciate your help in reviewing this patch. Please let us know if you disagree about this approach. If you'd like, we can discuss this upcoming tech-forum. [1]: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/21848 Thanks, Manish Badarkhe

Re: EHF and SPMD G0 interrupt handling issues

by Olivier Deprez

Hi Varun, * for platforms with SPMD_SPM_AT_SEL2=1. These platforms already use EHF for servicing RAS interrupts today. Can you please have a look at https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/16047 ? and https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/16047/6/docs… The model, by the FF-A specification, is to permit G0 interrupts to trap to EL3 when NWd runs. A G0 interrupt is routed to a SP through the SPMD/SPMC by the use of EL3-SP direct messages: https://review.trustedfirmware.org/q/topic:%22el3_direct_msg%22+(status:ope… When SEL1/0 runs, G0 interrupts are first trapped to SEL2 and forwarded to EL3 by the FFA_EL3_INTR_HANDLE ABI. I appreciate the legacy capability to let G0 interrupts trap to EL3 while SWd runs is not possible/recommended with this design. This might indeed break earlier implementations; would it make sense aligning SW stacks to the latest of the FF-A spec recommendations? I let Raghu chime in if need be. Regards, Olivier. ________________________________ From: Varun Wadekar via TF-A <tf-a(a)lists.trustedfirmware.org> Sent: 06 June 2023 13:12 To: TF-A Mailing List <tf-a(a)lists.trustedfirmware.org> Subject: [TF-A] EHF and SPMD G0 interrupt handling issues 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

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

[RFC] Common API to retrieve pre-allocated share memory for Transfer List

by Raymond Mao

Hi, I am currently doing research to implement the Transfer List to comply with Arm's firmware handoff spec ( https://github.com/FirmwareHandoff/firmware_handoff) in order to have a standardized handoff approach between different firmware stages during boot. The idea is to create a Transfer List in BL2 and cache it into a pre-allocated memory in SRAM that can be shared between BL2 and BL3x. A prototype currently available is creating APIs under qemu platform code to retrieve the pre-defined memory address (The shared memory region is defined in platform_def.h). But I think we need to define a common API for this purpose to support all platforms. Please share your views or any suggestions. Thanks. Regards, Raymond

[RFC] Proposed location to host the firmware handoff specification.

by Jose Marinho

Hi, Arm worked to draft a firmware handoff [1] specification, evolving it based on community feedback. This activity followed the request of some members of the Arm ecosystem [2]. The spec (still at ALP – feedback/comments welcome!) standardizes how information is propagated between different firmware components during boot. The spec hopes to remove the reliance on bespoke/platform-specific information handoff mechanisms, thus reducing the code maintenance burden. The concept of entry types is present in the spec – these are data structure layouts that carry a specific type of data. New types are meant to be added, following the needs and use-cases of the different communities. Thus, these communities should be empowered to request new types! To enable community contributions, the specification must be hosted in a location that is friendly to change requests. We propose to host the spec in trustedfirmware.org (tf.org). Tf.org hosts several open-source projects and already has an open governance model. TF-A, and the associated community, rely on tf.org, and thus are already well equipped to maintain this specification and keep it up to date. Tf.org is agnostic of any downstream projects that would adopt this specification (e.g. U-boot, EDK2, etc.). We welcome the views of the communities and want to understand if there are any strong objections to what’s being proposed! If anyone has objections, we are happy to consider alternatives and associated trade-offs.
