drm/nouveau/gr: enable memory loads on helper invocation on all channels We have a lurking bug where Fragment Shader Helper Invocations can't load from memory. But this is actually required in OpenGL and is causing random hangs or failures in random shaders. It is unknown how widespread this issue is, but shaders hitting this can end up with infinite loops. We enable those only on all Kepler and newer GPUs where we use our own Firmware. Nvidia's firmware provides a way to set a kernelspace controlled list of mmio registers in the gr space from push buffers via MME macros. v2: drop code for gm200 and newer.

drm/nouveau/gr/gf100-: make global attrib_cb actually global This was thought to be per-channel initially - it's not. The backing pages for the VMM mappings are shared for all channels. - switches to more straight-forward patch interfaces - prepares for sub-context support - this is saving a *sizeable* amount of vram v2: - whitespace Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com>

drm/nouveau/gr/gf100-gm10x: update register lists There are differences on GM200 and newer too, but we can't fix them there as they come from firmware packages. A request has been made to NVIDIA to release updated firmware. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau/gr/gf100-: virtualise dist_skip_table + improve algorithm The algorithm for GM200 and newer matches RM for all the boards I have, but I don't have enough data to try and figure something out for earlier boards, so these will still write zeroes to the table as we did before. The code in NVGPU isn't helpful here, it appears to handle specific cases. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau/gr/gf100-: virtualise alpha_beta_tables + improve algorithms I haven't yet been able to find a fully programatic way of calculating the same mapping as NVIDIA for GF100-GF119, so the algorithm partially depends on data tables for specific configurations. I couldn't find traces for every possibility, so the algorithm will switch to a mapping similar to what GK104-GM10x use if it encounters one. We did the wrong thing before anyway, so shouldn't matter too much. The algorithm used in the GK104 implementation was ported from NVGPU. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau/gr: namespace + nvidia gpu names (no binary change) The namespace of NVKM is being changed to nvkm_ instead of nouveau_, which will be used for the DRM part of the driver. This is being done in order to make it very clear as to what part of the driver a given symbol belongs to, and as a minor step towards splitting the DRM driver out to be able to stand on its own (for virt). Because there's already a large amount of churn here anyway, this is as good a time as any to also switch to NVIDIA's device and chipset naming to ease collaboration with them. A comparison of objdump disassemblies proves no code changes. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
