2015-04-20media-bus: Fixup RGB444_1X12, RGB565_1X16, and YUV8_1X24 media bus formatHEADmasterPhilipp Zabel2-8/+8
Change the constant values for RGB444_1X12, RGB565_1X16, and YUV8_1X24 media bus formats in anticipation of a merge conflict with the media tree, where the old values are already taken by RBG888_1X24, RGB888_1X32_PADHI, and VUY8_1X24, respectively.

2015-04-14drm/i915: Move drm_framebuffer_unreference out of struct_mutex for takeoverTvrtko Ursulin1-6/+8
intel_user_framebuffer_destroy() requires the struct_mutex for its object bookkeeping, so this means that all calls to drm_framebuffer_unreference must be held without that lock.

2015-04-14drm: Make integer overflow checking cover universal cursor updates (v2)Matt Roper1-11/+11
Our legacy SetPlane updates perform integer overflow checking on a plane's destination rectangle in drm_mode_setplane(), and atomic updates handled as part of a drm_atomic_state transaction do the same checking in drm_atomic_plane_check(). However legacy cursor updates that get routed through universal plane interfaces may bypass this overflow checking if the driver's .update_plane is serviced by the transitional plane helpers rather than the full atomic plane helpers. Move the check for destination rectangle integer overflow from the drm_mode_setplane() to __setplane_internal() so that it also covers cursor operations. This fixes an issue first noticed with i915 commit: commit ff42e093e9c9c17a6e1d6aab24875a36795f926e Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Mar 2 16:35:20 2015 +0100 Revert "drm/i915: Switch planes from transitional helpers to full atomic helpers" The above revert switched us from full atomic helpers back to the transitional helpers, and in doing so we lost the overflow checking here for universal cursor updates. Even though such extreme cursor positions are unlikely to actually happen in the wild, we still don't want there to be a change of behavior when drivers switch from transitional helpers to full helpers. v2: Move check from setplane ioctl to setplane_internal rather than adding an additional copy of the checks to the transitional plane helpers.

2015-04-14drm/nouveau/bios: fix fetching from acpi on certain systemsJan Vesely1-2/+2
nvbios_extend() returns 1 to indicate "extended the array" and 0 to indicate the array is already big enough. This is used by the core shadowing code to prevent re-fetching chunks of the image that have already been shadowed. The ACPI fetching code may possibly need to extend this further due to requiring fetches to happen in 4KiB chunks. Under certain circumstances (that happen if the total image size is a multiple of 4KiB), the memory allocated to store the shadow will already be big enough, causing the ACPI code's nvbios_extend() call to return 0, which is misinterpreted as a failure. The fix is simple, accept >= 0 as a successful condition here. The core will have already made sure that we're not re-fetching data we already have.

2015-04-14drm/nouveau/gem: allow user-space to specify an object should be coherentAlexandre Courbot2-0/+4
User-space use mappable BOs notably for fences, and expects that a value update by the GPU will be immediatly visible through the user-space mapping. ARM has a property that may prevent this from happening though: memory can be mapped multiple times only if the different mappings share the same caching properties. However all the lowmem memory is already identity-mapped into the kernel with cache enabled, so when user-space requests an uncached mapping, we actually get an "undefined caching policy" one and this has strange side-effects described on Freedesktop bug 86690. To prevent this from happening, allow user-space to explicitly specify which objects should be coherent, and create such objects with the TTM_PL_FLAG_UNCACHED flag. This will make TTM allocate memory using the DMA API, which will fix the identify mapping and allow us to safely map the objects to user-space uncached.
