Trusted Firmware-A v2.6 release activities in November

by Joanna Farley

TF-A Community, This is to notify that we are planning to target the Trusted Firmware-A 2.6 release during the fourth week of Nov 2021 as part of the regular 6 month cadence. The aim is to consolidate all TF-A work since the 2.5 release. As part of this, a release candidate tag will be created and release activities will commence from 15th November 2021 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 2.6 release are submitted in good time to be complete by 12th November 2021. 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 Jobs. We will endeavour minimise the disruption on patch merging and complete release activities ASAP after we start. Thanks Joanna

ARM Trusted memory Resolution

by IS20 Boaz Baron

Hi all, What is the resolution for secure memory space with the Trust zone? Is it dependent on the MMU resolution? Means, for example, If my MMU can set a range of 16 KB so can I set that range as a trusted zone as well? P.S. I have ARM A35 (I am not sure but I think my MMU supports a resolution of 32KB) You are welcome to comment if I have any mistakes Thanks a lot, Boaz. ________________________________ The privileged confidential information contained in this email is intended for use only by the addressees as indicated by the original sender of this email.

Re: [TF-A] TFA affinity power level

by Madhukar Pappireddy

Hi HPChen 1. Can try setting PLATFORM_MAX_AFFLVL to MPIDR_AFFLVL2? I am assuming your platform has 1 cluster with 2 cores. 2. The project currently supports a limited number of platforms. The default test suite[1] contains several smaller test suites. The tests are designed to auto-detect critical features supported by the platform. Rather than fail, tftf will skip tests if a feature is not supported. Please refer to the documentation for the tf-a-tests project here: https://trustedfirmware-a-tests.readthedocs.io/en/latest/index.html [1] https://git.trustedfirmware.org/TF-A/tf-a-tests.git/tree/tftf/tests/tests-s… Thanks, Madhukar -----Original Message----- From: TF-A <mailman-bounces(a)lists.trustedfirmware.org> On Behalf Of MS10 HPChen0 Sent: Tuesday, October 12, 2021 10:43 PM To: tf-a-owner(a)lists.trustedfirmware.org Subject: TFA affinity power level Hi, I'm Nuvoton software engineer. We have an A35 dual core platform. I ported the TFA for this platform. Now I want test the TFA on test suite. I have some questions. Please help to answer. Thanks! 1. If define 'PLATFORM_MAX_AFFLVL' to MPIDR_AFFLVL1. The tftf test only identify single core no matter 'PLATFORM_CORES_PER_CLUSTER' define to 2. How should I define 'PLATFORM_MAX_AFFLVL'? 2.

Support for passing 18 parameters to/from an SMC call in AArch64

by Rebecca Cran

I noticed TF-A currently supports passing in 4 parameters and returning up to 8. But SMCCC 1.1+ supports passing up to 18 and returning 18 in AArch64 mode, and passing in/out 8 in AArch32. I was wondering if there are any plans to add support for handling the full set of parameters? -- Rebecca Cran

[RFC]: UFS patches

by Jorge Troncoso

Hi all, We made a few changes to the UFS driver. The proposed patches are posted here: https://review.trustedfirmware.org/q/topic:%22ufs_patches%22+(status:open%2… . The patches mainly consist of the below changes: 1. Delete asserts. Return error values instead. 2. Add retry logic and timeouts. 3. Reuse ufshc_send_uic_cmd() for DME_GET and DME_SET commands. Any feedback/comments on these patches would be greatly appreciated. Thanks! Jorge Troncoso
