drm/radeon: fix include notation and remove -Iinclude/drm flag

2017-05-17T12:36:40+00:00

Include instead of relative path from include/drm, then remove the -Iinclude/drm compiler flag. Signed-off-by: Masahiro Yamada Reviewed-by: Michel Dänzer Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1493009447-31524-14-git-send-email-yamada.masahiro@socionext.com

Backmerge tag 'v4.11-rc6' into drm-next

2017-04-10T21:40:42+00:00

Linux 4.11-rc6 drm-misc needs 4.11-rc5, may as well fix conflicts with rc6.

drm/ttm: add io_mem_pfn callback

2017-04-05T03:33:42+00:00

This allows the driver to handle io_mem mappings on their own. Signed-off-by: Christian König Reviewed-by: Michel Dänzer Reviewed-by: Nicolai Hähnle Signed-off-by: Alex Deucher

drm/radeon: Override fpfn for all VRAM placements in radeon_evict_flags

2017-03-27T20:17:30+00:00

We were accidentally only overriding the first VRAM placement. For BOs with the RADEON_GEM_NO_CPU_ACCESS flag set, radeon_ttm_placement_from_domain creates a second VRAM placment with fpfn == 0. If VRAM is almost full, the first VRAM placement with fpfn > 0 may not work, but the second one with fpfn == 0 always will (the BO's current location trivially satisfies it). Because "moving" the BO to its current location puts it back on the LRU list, this results in an infinite loop.

mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf

2017-02-25T01:46:54+00:00

->fault(), ->page_mkwrite(), and ->pfn_mkwrite() calls do not need to take a vma and vmf parameter when the vma already resides in vmf. Remove the vma parameter to simplify things.

drm/mm: Convert to drm_printer

2016-12-30T11:08:28+00:00

Including all drivers. I thought about keeping small compat functions to avoid having to change all drivers. But I really like the drm_printer idea, so figured spreading it more widely is a good thing. v2: Review from Chris: - Natural argument order and better name for drm_mm_print. - show_mm() macro in the selftest.

mm: replace get_user_pages() write/force parameters with gup_flags

2016-10-19T15:11:43+00:00

This removes the 'write' and 'force' from get_user_pages() and replaces them with 'gup_flags' to make the use of FOLL_FORCE explicit in callers as use of this flag can result in surprising behaviour (and hence bugs) within the mm subsystem.
