2015-11-03drm/nouveau/ltc/gf100: add flush/invalidate functionsAlexandre Courbot
Allow clients to manually flush and invalidate L2. This will be useful for Tegra systems for which we want to write instmem using the CPU. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-11-03drm/nouveau/ltc: add hooks for invalidate and flushAlexandre Courbot
These are useful for systems without a coherent CPU/GPU bus. For such systems we may need to maintain the L2 ourselves. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-11-03drm/nouveau/timer: re-introduce nvkm_wait_xsec macrosAlexandre Courbot
Reintroduce macros allowing us to test a register against a certain mask, since this is the most common usage pattern for the more generic nvkm_xsec macros and makes the code more concise and readable.

2015-11-03drm/nouveau/pmu: do not assume a PMU is presentAlexandre Courbot
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 Mirkin
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 Szyprowski
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.

2015-10-30drm/tegra: dc: Request/free syncpoint at init/exitThierry Reding
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>

2015-10-30drm/imx: hdmi: fix HDMI setup to allow modes larger than FullHDLucas Stach
This worked before the dw-hdmi bridge code was changed to validate the setup data more strictly. Add back support for modes with a pixel clock up to 216MHz. Even higher clocks should work, but we are missing the required setup data for now. Also change the mode validate callbacks to disallow modes with higher pixelclocks, so we don't end up failing the modeset later on.
