Hello everyone,
it seems that GP10B support has regressed recently. With linux-next, I
need to modify device/base.c to set
.mmu = gp10b_mmu_new
for GP10B (makes sense - I guess this was left as gf100_mmu_new as a
typo) to probe. After that, running a trivial testcase (running a NOP
method in 3D class) fails with
[ 110.084649] nouveau 17000000.gpu: fifo: read fault at 0000011000

[ 125.084858] nouveau 17000000.gpu: nouveau_noop_te[2413]: failed to
idle channel 1 [nouveau_noop_te[2413]]
I haven't managed to track this down yet. However, I did find out that
checking out the drm/nouveau directory at commit "drm/nouveau/kms/nv50:
use the correct state for base channel notifier setup" makes things work
again.
I'll continue to take look, though bisecting is a bit harder than usual
due to some other issues in Tegra186 recently, so any pointers in the
right direction would be useful :)
Thanks,
Mikko
Bisection status report: The latest commit I have gotten to work is 10842ba074e9 drm/nouveau: remove unused nouveau_fence_work() i.e. the first bad commit is d7722134b825 drm/nouveau: switch over to new memory and vmm interfaces Even with the first one some patches/hacks are needed: - in mmu/gp10b.c, in the constructor we need to select the GM200 path - the GP100 path seems to not to work - as mentioned in the first mail, we need to set .mmu = gp10b_mmu_new, - and in nouveau_mem_memory_target we need to return NVKM_MEM_TARGET_NCOH instead of NVKM_MEM_TARGET_HOST.

on top of next-20171121 works at least for a simple test.
