2017-02-03drm: Improve drm_mm search (and fix topdown allocation) with rbtreesChris Wilson
The drm_mm range manager claimed to support top-down insertion, but it was neither searching for the top-most hole that could fit the allocation request nor fitting the request to the hole correctly. In order to search the range efficiently, we create a secondary index for the holes using either their size or their address. This index allows us to find the smallest hole or the hole at the bottom or top of the range efficiently, whilst keeping the hole stack to rapidly service evictions. v2: Search for holes both high and low. Rename flags to mode. v3: Discover rb_entry_safe() and use it! v4: Kerneldoc for enum drm_mm_insert_mode.

2016-10-25dma-buf: Rename struct fence to dma_fenceChris Wilson
I plan to usurp the short name of struct fence for a core kernel struct, and so I need to rename the specialised fence/timeline for DMA operations to make room. A consensus was reached in https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html that making clear this fence applies to DMA operations was a good thing.

Patches from Tobias Jakobi. - leftover patches for the connector reg/unreg cleanup (required that I backmerged drm-next) from Chris - last vgem fence patch from Chris - fix up warnings in the new sphinx gpu docs build - misc other small bits * tag 'topic/drm-misc-2016-07-22' of git://anongit.freedesktop.org/drm-intel: (57 commits) GPU-DRM-Exynos: Delete an unnecessary check before the function call "vunmap" GPU-DRM-sun4i: Delete an unnecessary check before drm_fbdev_cma_hotplug_event() drm/atomic: Delete an unnecessary check before drm_property_unreference_blob() drm/rockchip: analogix_dp: add missing clk_disable_unprepare() on error drm: drm_connector->s/connector_id/index/ for consistency drm/virtio: Fix non static symbol warning drm/arc: Remove redundant dev_err call in arcpgu_load() drm/arc: Fix some sparse warnings drm/vgem: Fix non static symbol warning drm/doc: Spinx leftovers drm/dp-mst: Missing kernel doc drm/dp-mst: Remove tx_down_in_progress drm/doc: Fix missing kerneldoc for drm_dp_helper.c drm: Extract&Document drm_irq.h drm/doc: document all the properties in drm_mode_config drm/drm-kms.rst: Remove unused drm_fourcc.h include directive drm/doc: Add kerneldoc for @index drm: Unexport drm_connector_unregister_all() drm/sun4i: Remove redundant call to drm_connector_unregister_all() drm/ttm: Delete an unnecessary check before the function call "ttm_tt_destroy" ...
2016-07-26Backmerge tag 'v4.7' into drm-nextDave Airlie
Linux 4.7 As requested by Daniel Vetter as the conflicts were getting messy.
2016-07-19Merge remote-tracking branch 'airlied/drm-next' into topic/drm-miscDaniel Vetter
Backmerge drm-next to be able to apply Chris' connector_unregister_all cleanup (need latest i915 and sun4i state for that). Also there's a trivial conflict in ttm_bo.c that git rerere fails to remember. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
2016-07-19drm/ttm: Delete an unnecessary check before the function call "ttm_tt_destroy"Markus Elfring
The ttm_tt_destroy() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

2016-07-07drm/ttm: remove TTM_BO_PRIV_FLAG_MOVINGChristian König
Instead of using the flag just remember the fence of the last move operation. This avoids waiting for command submissions pipelined after the move, but before accessing the BO with the CPU again.
