01:43grid: has anyone seen issues with x2apic+iommu (really just x2apic) enabled in combination with amdgpu + zen4 (7950x) igpu? the whole system hangs when X starts, and i get intermittent messages like this: https://photos.app.goo.gl/WkokMvv5PBwF5sLTA running 6.3.8
01:44grid: idk if i really need x2apic, was just trying to get full hardware enablement w/rt kvm. any suggestions?
01:46grid: motherboard is asus proart x670e w/latest bios from mid-may
01:52grid: oh, and not sure if it matters, but i'm using a usb4 to displayport adapter.
10:04Triang3l: and now it actually hangs because of a later pipeline stage :DDDDD
10:05Triang3l: if I set up CB_COLOR0, regardless of CB_TARGET_MASK and CB_COLOR_CONTROL MODE = CB_DISABLE :P
10:06Triang3l: But going to research tomorrow, though it might have been because I wasn't setting DIM to 0 unlike R600g (DIM WIDTH_MAX/HEIGHT_MAX are only needed for RATs apparently), but looks like nope
10:07Triang3l: but R600g packets should be a good reference for things like INFO, ATTRIB, though they seem correct to me at least at first glance
13:21DottorLeo: hi!
13:59agd5f: grid, is there a bios option to disable ATS? can you try that. Alternatively, you can try and append pci=noats on the kernel command line
14:00grid: agd5f: will give it a try later, thanks!
14:26grid: i don't see any reference to ATS in the bios manual
14:26grid: heATSink ;)
14:42agd5f: grid, might also be called something like GPU Host Translation Cache
14:55grid: agd5f: yep that's there.
15:11agd5f: grid, try disabling that
15:35grid: agd5f: same deal with translation cache disabled and translation cache disabled + pci=noats
