drm/ttm: expose CPU address of DMA-allocated pages

2014-08-09T15:08:03Z

Pages allocated using the DMA API have a coherent memory mapping. Make this mapping visible to drivers so they can decide to use it instead of creating their own redundant one. Signed-off-by: Alexandre Courbot Acked-by: David Airlie Signed-off-by: Ben Skeggs

drm/ttm: fix handling of TTM_PL_FLAG_TOPDOWN v2

2014-07-08T01:15:58Z

bo->mem.placement is not initialized when ttm_bo_man_get_node is called, so the flag had no effect at all. v2: change nouveau and vmwgfx as well Signed-off-by: Christian König Cc: stable@vger.kernel.org Signed-off-by: Dave Airlie

drm/ttm: remove declaration of ttm_tt_cache_flush

2014-07-07T22:29:57Z

ttm_tt_cache_flush's implementation was removed in 2009 by commit c9c97b8c, but its declaration has been hiding in ttm_bo_driver.h since then. It has been surviving in the dark for too long now ; give it the mercy blow. Reviewed-by: Thierry Reding Reviewed-by: David Herrmann Signed-off-by: Alexandre Courbot Signed-off-by: David Herrmann

drm/ttm: fix kerneldoc of ttm_bo_create

2014-05-26T02:54:09Z

The kerneldoc header of ttm_bo_create() was referring to another (nonexisting) function and had a few obsolete or incorrect arguments. Signed-off-by: Alexandre Courbot Reviewed-by: David Herrmann Signed-off-by: Dave Airlie

drm: Add support for two-ended allocation, v3

2014-04-03T23:28:14Z

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. Based on drm_mm work by Chris Wilson. v3: Changed to use a TTM placement flag v2: Updated kerneldoc Cc: Chris Wilson Cc: Ben Widawsky Cc: Christian König Signed-off-by: Lauri Kasanen Signed-off-by: David Airlie

drm: init TTM dev_mapping in ttm_bo_device_init()

2014-03-16T11:23:42Z

With dev->anon_inode we have a global address_space ready for operation right from the beginning. Therefore, there is no need to do a delayed setup with TTM. Instead, set dev_mapping during initialization in ttm_bo_device_init() and remove any "if (dev_mapping)" conditions.
