2014-04-04drm/cma: Use dma_mmap_writecombine() to mmap bufferLaurent Pinchart1-2/+11
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 Iwai1-0/+11
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.

This decreases eviction by up to 20%, by improving the fragmentation quality. No harm in normal cases that fit VRAM fully (PTS gaming suite). 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. Other drivers may need different thresholds according to their workloads. v2: Nicer formatting Signed-off-by: Lauri Kasanen <[email protected]> Reviewed-by: Christian König <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
2014-04-04drm: Add support for two-ended allocation, v3Lauri Kasanen6-26/+92
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.
