drm/nouveau/nvkm: add a replacement for nvkm_notify This replaces the twisty, confusing, relationship between nvkm_event and nvkm_notify with something much simpler, and less racey. It also places events in the object tree hierarchy, which will allow a heap of the code tracking events across allocation/teardown/suspend to be removed. This commit just adds the new interfaces, and passes the owning subdev to the event constructor to enable debug-tracing in the new code. v2: - use ?: (lyude) Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com>

drm/nouveau/gpio: check function 76 in the power check as well Added GPIO is "Power Alert". It's uncertain if this GPIO is set on GPU initialization or only if a change is detected by the GPU at runtime. This GPIO can be found on Tesla and sometimes on Fermi GPUs. Untested, wrote according to documentation. Signed-off-by: Mark Menzynski <mmenzyns@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau/gpio: fail if gpu external power is missing Currently, nouveau doesn't check if GPU is missing power. This patch makes nouveau fail when this happens on latest GPUs. It checks GPIO function 121 (External Power Emergency), which should detect power problems on GPU initialization. This can be disabled with nouveau.config=NvPowerChecks=1 Tested on TU104, GP106 and GF100. v3: * Add config override for disabling power checks Signed-off-by: Mark Menzynski <mmenzyns@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau/gpio: 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>

drm/nouveau: remove symlinks, move core/ to nvkm/ (no code changes) The symlinks were annoying some people, and they're not used anywhere else in the kernel tree. The include directory structure has been changed so that symlinks aren't needed anymore. NVKM has been moved from core/ to nvkm/ to make it more obvious as to what the directory is for, and as some minor prep for when NVKM gets split out into its own module (virt) at a later date.
