Horrifying, and not what I wanted to read my last day before 2 weeks of leave. Let's drop this patch, hopefully by the time I'm back, your friends in GPU can confirm that's a spec bug and not an actual hardware/driver one...
Can you apply the other 3 patches in the mean time? Thanks :-)
Yeah, sure. I'll push the first 3 to drm-misc-next-fixes (should land in v5.15).
It's interesting that if my (new) reading of the spec is correct then kbase has been horribly broken in this respect forever. So clearly it can't be something that crops up very often. It would have been good if the spec could have included wording such as "naturally aligned" if that's what was intended.
Indeed. Fingers crossed this is a mix-up. Although the text you quoted seems pretty clear unfortunately :|
Enjoy your holiday!
Thanks!
