I still haven't gotten around to figure out how to make this work with qemu or taken the time to set it up on $work boards two years later so I'll have to trust you on actual tests, but it can't hurt to review. While I'm buying time here, I'm not one to praise our new robot overlords but since it made the news I had a look and noticed sashiko.dev ran on the patches: https://sashiko.dev/#/patchset/20260319-9pfixes-v1-0-c977a7433185%40pengutronix.de >From a quick look of the above there are a lot of questions raised and I don't think it's necessarily worth the time to answer all of them, but if you have time to skim through them and pick up anything interesting please say so (as far as I'm concerned the usb setup is intended for a mostly trusted setup in the first place... But then again this patch series started with a security concern, so where do we start considering races could be an issue?) Thanks, -- Dominique Martinet | Asmadeus
