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

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
