2015-11-03drm/nouveau/pmu: do not assume a PMU is presentAlexandre Courbot1-1/+1
Some devices may not have a PMU. Avoid a NULL pointer dereference in such cases by checking whether the pointer given to nvkm_pmu_pgob() is valid. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-11-03drm/nouveau/gem: return only valid domain when there's only oneIlia Mirkin1-2/+3
On nv50+, we restrict the valid domains to just the one where the buffer was originally created. However after the buffer is evicted to system memory, we might move it back to a different domain that was not originally valid. When sharing the buffer and retrieving its GEM_INFO data, we still want the domain that will be valid for this buffer in a pushbuf, not the one where it currently happens to be. This resolves fdo#92504 and several others. These are due to suspend evicting all buffers, making it more likely that they temporarily end up in the wrong place.

2015-11-03drm/exynos/gem: remove DMA-mapping hacks used for constructing page arrayMarek Szyprowski1-24/+32
Exynos GEM objects contains an array of pointers to the pages, which the allocated buffer consists of. Till now the code used some hacks (like relying on DMA-mapping internal structures or using ARM-specific dma_to_pfn helper) to build this array. This patch fixes this by adding proper call to dma_get_sgtable_attrs() and using the acquired scatter-list to construct needed array. This approach is more portable (work also for ARM64) and finally fixes the layering violation that was present in this code.

struct_mutex is being locked for every plane in intel_prepare_plane_fb and intel_cleanup_plane_fb. Require the caller to hold the mutex, and only acquire the mutex for each helper call. This way the lock only needs to be acquired twice in ->atomic_commit(). Once for pinning new framebuffers at the start, the second time for unpinning old framebuffer.

2015-10-30drm/tegra: dc: Request/free syncpoint at init/exitThierry Reding1-7/+7
syncpoints are resources provided by host1x and their lifetime is tied to the host1x device. They are not properly reference counted either, so removing the host1x device before any of its clients causes a use-after- free error. Adding proper reference counting would be a major enterprise so work around it for now by requesting and freeing the syncpoint at init and exit time, respectively. The host1x device is guaranteed to be around at this point. Signed-off-by: Thierry Reding <treding@nvidia.com>
