This is clearly hard, complicated work n= ot a lot of people could do. With how complex GPUs are (and the hardware variety there is), I don't see how else it could be done than by making it as easy = as possible to integrate existing drivers with as little modifications as possible. Making new drivers would be an INSANE amount of work... amdgpu does work a lot better here on an RX560 with pretty much constant us= e on 13-STABLE. It just works. Pretty much perfectly. The only problem I can not= ice is rare, temporary screen corruption sometimes (but I saw those on Windows = too, though more rarely). But radeonkms still panics. As you said it's really old hardware at this po= int but it's what's built-in the motherboard of a lot of older computers. The panics can take days or weeks to happen though and it seems pretty damn ran= dom. I can imagine something like this must be hell to debug. And running deskto= ps on old computers is probably not something a lot of people are gonna want to do... It would make more sense to prioritize supporting newer GPUs I suppos= e. Though those old Radeon cards can be useful for boards/CPUs without integra= ted graphics (especially since we're in a GPUpocalypse right now). (In reply to Bill Paul from comment #11) Oh wow seems like you narrowed it down a lot. radeonkms panics still happened for me on 14-CURRENT (with the corresponding drm-kmod port). I only noticed them on a test computer that wasn't getting a lot of desktop use (but that was left on running things) so it's hard to sa= y if they were more or less frequent. When I'm done shuffling hardware I'm gonna get my radeonkms test computer b= ack on my desk and leave it running and gather more infos on crashes if that he= lps. In my case it wasn't easy to trigger the panics. It could take a few days.= I could try whatever versions you think might be useful. --=20 You are receiving this mail because: You are the assignee for the bug.=
