GIC-600 errata 1717652: missed wake requests

by Okash Khawaja

Hi, It seems like TF-A's GIC600 driver currently doesn't have support for the Cat B errata 1717652 "Wake_request may not be delivered if multiple cores are woken by PPIs at the same time". Are there plans to support this? Thanks, Okash

Title: TF-A Tech Forum Agenda for Session on 27th January 2020Introduction of Arm CCA Context ManagementSession Presented by: Manish Pandey, Soby Mathew and Zelalem AwekeDetails: With the introduction of Arm CCA, the context management library needs to manage the context for one more world (realm world).

RFC for context management refactoring in TF-A

by Soby Mathew

Hello Everyone, We have a proposal to refactor the Context management framework in TF-A and an RFC is pushed for review here: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/13651 . The abstract of the RFC is given below: With the introduction of Arm CCA, the context management library needs to manage the context for one more world (realm world). Since the current context management library has evolved over time, some of design principles need sharpening / re-defining to make it easier to manage and make it less error-prone when managing the 3 worlds. The proposal lists down the design principles and discusses about introduction of new CPU Context for the root world (EL3). The refactor will increase the overall robustness of EL3 firmware as it will enforce a design pattern in software plus have a more predictable sysreg state during execution at EL3. The plus point here is that many of the design principles are already adhered to in one way or other in the current the implementation so much of the work can be done in an incremental fashion without much disruption. Along with @Zelalem Aweke<mailto:Zelalem.Aweke@arm.com> and @Manish Pandey2<mailto:Manish.Pandey2@arm.com>, we hope to discuss the this RFC and how this translates to code changes in TF-A during the Tech Forum this week. Best Regards Soby Mathew

About arm_validate_ns_entrypoint in arm_pm.c

by Ming Huang

Hi, arm_validate_ns_entrypoint() in plat/arm/common/arm_pm.c check ARM_NS_DRAM1_BASE and ARM_NS_DRAM2_BASE only, for some platform there are include more than two non-secure dram areas. It will bring dependencies between TF-A and physical memory space which can get from uefi atfer memory initialization, if arm_validate_ns_entrypoint() include the entire physical memory space. In my mind, the kernel should guarantee the validity of entry point. So why this check is need? Thanks, Ming

imx8mm-evk does not boot kernel 5.16 with mainline TF-A

by Fabio Estevam

Hi, I am running U-Boot 2022.01 on imx8mm-evk. If I build the NXP vendor-based TF-A (imx_5.4.47_2.2.0) I am able to boot kernel 5.16 just fine. However, if I use the upstream TF-A (v2.5 or v2.6), the kernel fails to boot most of the attempts. Peng, Jacky, Could you please try booting kernel 5.16 + U-Boot 2022.01 built with TF-A v2.6? What is missing in upstream TF-A to be able to boot kernel 5.16? Thanks, Fabio Estevam

fw update & anti-rollback versioning

by Etienne CARRIERE

Dear all, (and may the new year be happy to you and your beloved) In the course of evaluating the FW update flows for systems with FIP images, we identified the following requirements: Req1: The FIP image, or the components in the FIP, must have a version field. Each version field will be compared against the anti-rollback counter of the platform that the FIP or its component is bound to. Req2: We must be able to increment the FIP version field (though a FIP image FW update) without affecting the anti-rollback counter value. The anti-rollback counter should be incremented only for security updates upon explicit request. Req3: The version field should be present even if the FIP does not contain image certificates. Currently the FIP carries a version field in the different certificates, the anti-rollback counters are updated every time the root certificate value increased. This is not flexible enough and does not allow trial/acceptance of updates. Can we open a discussion on how to enhance the version/anti-rollback counter update in TF-A? Best regards, Etienne Carriere ST Restricted
