That sounds like something I would have been involved in, but I'm not
sure what you mean...

I fixed the amdgpu/radeon kernel drivers to obey the general KMS rules
for vblank vs page flips, and added DRM_MODE_PAGE_FLIP_TARGET to allow
userspace to take advantage of our hardware's capabilities to avoid
delaying a page flip by one refresh cycle in some cases. That's all.

That's a weird insinuation. If RADV was a "thorn for AMD", surely we'd
be having a party about this regression instead of insisting that it be
fixed thoroughly.
