Issue with adding ssh key to review server

by sparlane＠gmail.com

Hi All, Sorry if this is the wrong list, I'm trying to submit a patch for tf-a and I'm currently unable to add an ssh key or generate an https password to use for authentication. Perhaps I am doing something wrong? I'm trying to use the settings here: https://review.trustedfirmware.org/settings/#HTTPCredentials to add an ssh key and I get the error message "Error 500 (Server Error): Internal server error Endpoint: /accounts/self/sshkeys" Any help is greatly appreciated. Thanks, Scott (sparlane)

How to trap aborts caused by TZASC?

by Chenxu Wang

Hi all, I want to test how to trap the aborts caused by TZASC. For example, when I use NS-EL1 (e.g., OS) to access a Secure region (configured in TZASC), it will generate an abort. But I am not sure how to trap it. I think it is an external abort, so I enable the SCR_EL3.EA=1 and write a handler. However I cannot trap it. Also, my other handlers in EL3 still do not report the abort. Thus, how can I trap a TZASC abort? If I want to route it into EL3 to handle, how can I do it? Sincerely, WANG Chenxu

Does FVP and current TF-A support the SVE/SVE2 programming?

by Chenxu Wang

Hi all, I want to perform some encryption/decryption in TF-A. I find that Arm provides some hardware-assisted instructions for encryption and integrity verification (e.g., AESE, SHA1...). But it seems that FVP does not support them. I recently read Armv9 and know that Arm purposes SVE/SVE2 to accelerate the matrix computation. It seems that it can be another approach to accelerate the encryption. Since I am a novice in Armv9 (and in FVP), thus, I want to ask: (1) Do FVP and TF-A support the SVE? If yes, how to configure it? (2) Do FVP and TF-A support the SVE2? If yes, how to configure it? Looking forward to your reply! Sincerely, WANG Chenxu

TF-A CI often fail due to missing rebase

by Julius Werner

Hi Glen, Don, and others, I've seen that a couple of TF-A patches I've been CCed on recently often seem to fail the CI run (Allow-CI+1) due to some strange build-time errors that don't seem to have anything to do with the patch at hand, and then one of the maintainers usually suggests that the patch needs a rebase, and the next CI run succeeds after that. Here are two recent examples: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/16160 https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/14666 I was wondering if this is a known problem and if the CI can do anything here to mitigate it and save developers from this extra layer of friction? I'm not really sure why a rebase was necessary in either of these examples or why the CI run failed before it (unless the whole repository was in a bad state that didn't build, but since all submissions are guarded by the CI that shouldn't have been possible?). But I also don't really understand why the rebase would make a difference for the CI anyway. Generally, when a patch is submitted in Gerrit, that means it is cherry-picked onto the current master (regardless of what parent commit it was uploaded with). Since the CI is supposed to be a test run for submission, I would expect that the CI should also test a patch by cherry-picking it onto the current master, not just by building the patch on top of whatever parent commit it was uploaded with. But since rebasing a patch evidently seems to make a difference to the CI, that suggests that it's currently doing the latter strategy? Should that maybe be changed to the former to avoid these kinds of issues? If this isn't a known problem yet maybe it would be worth adding it to the JIRA? Thanks, Julius
