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 engine 06

...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.

From: Thierry Reding <treding at nvidia.com> Hi Ben, these are a couple of patches that are in preparation for adding GV11B support. The fundamental issue that these are trying to solve is that the GV11B is the first Tegra incarnation of the GPU where the aperture really matters. All prior generations would accept any of them. For dGPUs we usually allocate memory in VRAM, so the default
