2017-02-17drm/nouveau/gm20b: add dummy PMU deviceAlexandre Courbot1-0/+1
Add a dummy PMU device so the PMU falcon is instanciated and can be used by secure boot. We could reuse gk20a's implementation here, but it would fight with secboot over PMU falcon's ownership and secboot will reset the PMU, preventing it from operating afterwards. Proper handout between secboot and pmu is coming along with the actual gm20b PMU implementation, so use this as a temporary solution.

2016-12-13drm/nouveau/fifo/gf100-: recover from host mmu faultsBen Skeggs4-28/+29
This has been on the TODO list for a while now, recovering from things such as attempting to execute a push buffer or touch a semaphore in an unmapped memory area. The only thing required on the HW side here is that the offending channel is removed from the runlist, and *not* a full reset of PFIFO. This used to be a bit messier to handle before the rework to make use of engine topology info, but is apparently now trivial. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2016-11-07drm/nouveau/fifo/gf100-: protect channel preempt with subdev mutexBen Skeggs2-6/+11
This avoids an issue that occurs when we're attempting to preempt multiple channels simultaneously. HW seems to ignore preempt requests while it's still processing a previous one, which, well, makes sense. Fixes random "fifo: SCHED_ERROR 0d []" + GPCCS page faults during parallel piglit runs on (at least) GM107. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Cc: stable@vger.kernel.org
2016-11-07drm/nouveau/gr: fallback to legacy paths during firmware lookupAlexandre Courbot1-4/+46
Look for firmware files using the legacy ("nouveau/nvxx_fucxxxx") path if they cannot be found in the new, "official" path. User setups were broken by the switch, which is bad. There are only 4 firmware files we may want to look up that way, so hardcode them into the lookup function. All new firmware files should use the standard "nvidia/<chip>/gr/" path.

2016-10-12drm/nouveau/pci: set streaming DMA mask earlyArd Biesheuvel1-10/+27
Some subdevices (i.e., fb/nv50.c and fb/gf100.c) map a scratch page using dma_map_page() way before the TTM layer has had a chance to set the DMA mask. This may prevent the driver from loading at all on platforms whose system memory is not covered by the default DMA mask of 32-bit (i.e., when all RAM is above 4 GB). So set a preliminary DMA mask right after constructing the PCI device, and base it on the .dma_bits member of the MMU subdevice, which is what the TTM layer will base the DMA mask on as well.

2016-07-14drm/nouveau/bus: remove cpu_coherent flagAlexandre Courbot2-2/+0
This flag's only remaining function is to ignore the uncached flag for BOs on coherent architectures. However the reason for allocating an object uncache on a non-coherent architecture (namely because the cost of doing explicit flushes/ invalidations is higher than the benefit of caching the data because accesses are few and far between) should also apply on architectures for which coherency is maintained implicitly. Thus allocate coherent objects as uncached on all architectures. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
