22:30 karolherbst: imirkin: I am hitting this bug :) https://bugs.freedesktop.org/show_bug.cgi?id=110797
22:31 karolherbst: probably even the same GPU
22:31 imirkin: you're secretly that guy ;)
22:31 karolherbst: nah
22:31 karolherbst: must have been mupuf as it was his GPU :D
22:31 imirkin: hehe
22:31 karolherbst: the GPUs arrived today so I tried them all out
22:32 imirkin: well, the final note is that windows didn't work either
22:32 karolherbst: strange
22:32 karolherbst: should I try booting windows?
22:32 imirkin: or try the blob
22:33 imirkin: (but you need a slightly old blob, coz they dropped fermi i think)
22:34 karolherbst: ahh, right
22:34 karolherbst: nvidia warns about it actually :D
22:34 karolherbst: let's see
22:40 karolherbst: imirkin: seems to work
22:41 karolherbst: yep. "OpenGL core profile version string: 4.6.0 NVIDIA 390.144"
22:42 imirkin: ok
22:42 imirkin: so they know something we don't
22:42 karolherbst: I have a vague idea on what it will be
22:42 karolherbst: as the reg we read is pure bs
22:43 karolherbst: PXBAR.GPC_UNK1[0x2]+0x54
22:43 karolherbst: no idea why we touch it for disp stuff :p
22:47 imirkin: probably because blob did it? who knows
23:03 RSpliet: I don't think that the MMIO fault and the backtrace are necessarily oe and the same
23:05 RSpliet: What I mean is that the failing MMIO write isn't done inside nvkm_outp_init. It's a different fault. The WARNING is controlled even. https://elixir.bootlin.com/linux/v5.0.17/source/drivers/gpu/drm/nouveau/nvkm/engine/disp/outp.c#L191
23:08 karolherbst: imirkin: okay.. so that write is from inside devinit
23:09 karolherbst: I suspect the disp engine is down or something...
23:10 karolherbst: mhh
23:13 karolherbst: I have an idea...
23:13 imirkin: does it involve a blowtorch?
23:14 karolherbst: kind of
23:14 imirkin: hehe
23:17 RSpliet: What, just forcefully remove all old NVIDIA cards from the face of the planet?
23:19 karolherbst: imirkin: okay.. so.. ehh.. nvidia fails to load after nouveau messes with the GPU :D
23:20 imirkin: nouveau fails to load after nvidia
23:20 imirkin: so i guess the feeling is mutual
23:21 karolherbst: didn't test it this way :D
23:21 imirkin: iirc they do something to the gpu that we don't recover from
23:21 imirkin: it's gone back and forth a few times though
