2014-04-04drm/exynos: add DSIM driverAndrzej Hajda
The patch adds driver for Exynos DSI master (DSIM). It is a platform driver which is registered as exynos_drm_display sub-driver of exynos_drm framework and implements DRM encoder/connector pair. It is also MIPI-DSI host driver and provides DSI bus for panels. It interacts with its panel(s) using drm_panel framework.

2014-04-04drm/exynos: disallow fbdev initialization if no device is connectedAndrzej Hajda

2014-04-04drm/mipi_dsi: add flags to DSI messagesAndrzej Hajda
This patch adds flags field to mipi_dsi_msg structure and two flags: - MIPI_DSI_MSG_REQ_ACK - request ACK from peripheral for given message, - MIPI_DSI_MSG_USE_LPM - use Low Power Mode to transmit message. The first flag is usually helpful during DSI diagnostic, the second flag is required by some peripherals during configuration phase.

2014-04-04drm/i915: move power domain init earlier during system resumeImre Deak
During resume the intel hda audio driver depends on the i915 driver reinitializing the audio power domain. Since the order of calling the i915 resume handler wrt. that of the audio driver is not guaranteed, move the power domain reinitialization step to the resume_early handler. This is guaranteed to run before the resume handler of any other driver. The power domain initialization in turn requires us to enable the i915 pci device first, so move that part earlier too. Accordingly disabling of the i915 pci device should happen after the audio suspend handler ran. So move the disabling later from the i915 resume handler to the resume_late handler. v2: - move intel_uncore_sanitize/early_sanitize earlier too, so they don't get reordered wrt. intel_power_domains_init_hw() Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=76152 Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Takashi Iwai <tiwai@suse.de> Cc: stable@vger.kernel.org [danvet: Add cc: stable and loud comments that this is just a hack.] [danvet: Fix "Should it be static?" sparse warning reported by Wu Fengguang's kbuilder.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2014-04-04drm/cma: Use dma_mmap_writecombine() to mmap bufferLaurent Pinchart
The GEM CMA helpers uses a custom mmap implementation based on remap_pfn_range(). While this works when the buffer DMA and physical addresses are identical, it fails to take IOMMU into account and tries to mmap the buffer to userspace using the DMA virtual address instead of the physical address. This results in mapping random physical pages when the device is behind an IOMMU. Use the DMA mapping dma_mmap_writecombine() function instead.

2014-04-04drm: Prefer noninterlace cmdline mode unless explicitly specifiedTakashi Iwai
Currently drm_pick_cmdline_mode() doesn't care about the interlace when the given mode line has no "i" suffix. That is, when there are multiple entries for the same resolution, an interlace mode might be picked up just depending on the assigned order, and there is no way to exclude it. This patch changes the logic for the mode selection, to prefer the noninterlace mode unless the interlace mode is explicitly given. When no matching mode is found, it still tries the interlace mode as fallback.

In some cases, even the VRAM-fitting cases improved slightly (openarena, urban terror). 512kb was measured as the most optimal threshold for 3d workloads common to radeon.

2014-04-04drm: Add support for two-ended allocation, v3Lauri Kasanen
Clients like i915 need to segregate cache domains within the GTT which can lead to small amounts of fragmentation. By allocating the uncached buffers from the bottom and the cacheable buffers from the top, we can reduce the amount of wasted space and also optimize allocation of the mappable portion of the GTT to only those buffers that require CPU access through the GTT. For other drivers, allocating small bos from one end and large ones from the other helps improve the quality of fragmentation.
