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