It's big, but jam packed will lots of features and of course 0 regressions. (okay maybe there'll be one). Highlights: - new KMS drivers for server GPU chipsets: ast, mgag200 and cirrus (qemu only). These drivers use the generic modesetting drivers. - initial prime/dma-buf support for i915, nouveau, radeon, udl and exynos - switcheroo audio support: so GPUs with HDMI can turn off the sound driver without crashing stuff. - There are some patches drifting outside drivers/gpu into x86 and EFI for better handling of multiple video adapters in Apple Macs, they've got correct acks except one trivial fixup. - Core: edid parser has better DMT and reduced blanking support, crtc properties, plane properties, - Drivers: exynos: add 2D core accel support, prime support, hdmi features intel: more Haswell support, initial Valleyview support, more hdmi infoframe fixes, update MAINTAINERS for Daniel, lots of cleanups and fixes radeon: more HDMI audio support, improved GPU lockup recovery support, remove nested mutexes, less memory copying on PCIE, fix bus master enable race (kexec), improved fence handling gma500: cleanups, 1080p support, acpi fixes nouveau: better nva3 memory reclocking, kepler accel (needs external firmware rip), async buffer moves on nv84+ hw. I've some more dma-buf patches that rely on the dma-buf merge for vmap stuff, and I've a few fixes building up, but I'd decided I'd better get rid of the main pull sooner rather than later, so the audio guys are also unblocked."

| | | | | | | | | | | | | | | | | | This patch splits the DMM off into a separate sub-device, in order to utilize the platform device information that was created as part of the OMAP hwmod entry for the DMM. The driver probe function queries the iomem resource and IRQ using standard platform_get functions. The OMAP DRM driver now calls the platform_driver_register() function for the subordinate DMM driver inside its probe function. This guarantees the required order for the DMM and ensures the DMM resources are available for use by the DRM driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support in framebuffer objects for other color formats and multi- planar YUV (NV12). Since this requires changing the API between the plane and fb for getting scanout information (paddr, etc), take advantage of the opportunity and put in place a way to allow fb's to be unpinned when they are not being scanned out. Now, before start of scanout the plane calls omap_framebuffer_pin() which takes care to pin all the backing bo's, then omap_framebuffer_update_scanout() however many times to update the scanout address(es), etc, and then when finished omap_framebuffer_unpin().

* drm/omap: add GEM support for tiled/dmm buffersRob Clark2011-12-086-37/+466
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TILER/DMM provides two features for omapdrm GEM objects: 1) providing a physically contiguous view to discontiguous memory for hw initiators that cannot otherwise support discontiguous buffers (DSS scanout, IVAHD video decode/encode, etc) 2) providing untiling for 2d tiled buffers, which are used in some cases to provide rotation and reduce memory bandwidth for hw initiators that tend to access data in 2d block patterns. For 2d tiled buffers, there are some additional complications when it comes to userspace mmap'ings. For non-tiled buffers, the original (potentially physically discontiguous) pages are used to back the mmap. For tiled buffers, we need to mmap via the tiler/dmm region to provide an unswizzled view of the buffer. But (a) the buffer is not necessarily pinned in TILER all the time (it can be unmapped when there is no DMA access to the buffer), and (b) when they are they are pinned, they not necessarily page aligned from the perspective of the CPU. And non-page aligned userspace buffer mapping is evil. To solve this, we reserve one or more small regions in each of the 2d containers when the driver is loaded to use as a "user-GART" where we can create a second page-aligned mapping of parts of the buffer being accessed from userspace. Page faulting is used to evict and remap different regions of whichever buffers are being accessed from user- space.

* drm/omap: DMM/TILER support for OMAP4+ platformAndy Gross2011-12-0811-11/+2143
| | | | | | | | | | | | | | | | | | | | | | | | Dynamic Memory Manager (DMM) is a hardware block in the OMAP4+ processor that contains at least one TILER instance. TILER, or Tiling and Isometric Lightweight Engine for Rotation, provides IOMMU capabilities through the use of a physical address translation table. The TILER also provides zero cost rotation and mirroring. The TILER provides both 1D and 2D access by providing different views or address ranges that can be used to access the physical memory that has been mapped in through the PAT. Access to the 1D view results in linear access to the underlying memory. Access to the 2D views result in tiled access to the underlying memory resulted in increased efficiency. The TILER address space is managed by a tiler container manager (TCM) and allocates the address space through the use of the Simple Tiler Allocation algorithm (SiTA). The purpose of the algorithm is to keep fragmentation of the address space as low as possible.

* staging: add omapdrm DRM/KMS driver for TI OMAP platformsRob Clark2011-11-2614-0/+3491
A DRM display driver for TI OMAP platform. Similar to omapfb (fbdev) and omap_vout (v4l2 display) drivers in the past, this driver uses the DSS2 driver to access the display hardware, including support for HDMI, DVI, and various types of LCD panels. And it implements GEM support for buffer allocation (for KMS as well as offscreen buffers used by the xf86-video-omap userspace xorg driver). The driver maps CRTCs to overlays, encoders to overlay-managers, and connectors to dssdev's. Note that this arrangement might change slightly when support for drm_plane overlays is added. For GEM support, non-scanout buffers are using the shmem backed pages provided by GEM core (In drm_gem_object_init()). In the case of scanout buffers, which need to be physically contiguous, those are allocated with CMA and use drm_gem_private_object_init(). See userspace xorg driver: git://github.com/robclark/xf86-video-omap.git Refer to this link for CMA (Continuous Memory Allocator): http://lkml.org/lkml/2011/8/19/302 Links to previous versions of the patch: v1: http://lwn.net/Articles/458137/ v2: http://patches.linaro.org/4156/ v3: http://patches.linaro.org/4688/ v4: http://patches.linaro.org/4791/ History: v5: move headers from include/drm at Greg KH's request, minor rebasing on 3.2-rc1, pull in private copies of drm_gem_{get,put}_pages() because "drm/gem: add functions to get/put pages" patch is not merged yet v4: bit of rework of encoder/connector _dpms() code, modeset_init() rework to not use nested functions, update TODO.txt v3: minor cleanups, improved error handling for dev_load(), some minor API changes that will be needed later for tiled buffer support v2: replace omap_vram with CMA for scanout buffer allocation, remove unneeded functions, use dma_addr_t for physical addresses, error handling cleanup, refactor attach/detach pages into common drm functions, split non-userspace-facing API into omap_priv.h, remove plugin API v1: original Signed-off-by: Rob Clark <rob@ti.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
