[PATCH 00/13] drm: Enable buddy allocator support
by Arunpravin 22 Oct '21

22 Oct '21

This series of patches implemented to move i915 buddy allocator to drm root, and introduce new features include - make drm_buddy_alloc a prime vehicle for allocation - TOPDOWN range of address allocation support - a function to free unused pages on contiguous allocation - a function to allocate required size comply with range limitations - cleanup i915 and amdgpu old mm manager references - and finally add drm buddy support to i915 and amdgpu driver modules selftest patches will be sent in a separate series.

PATCH [v2 0/7] drm/bridge: Drop deprecated functions
by Sam Ravnborg 22 Oct '21

22 Oct '21

Over time we have accumulated some deprecated functions etc. in drm_bridge. This patch-set starts to move over to the atomic variants and deletes what is not used anymore. There was only one user of the non-atomic drm_bridge_chain functions in parade-ps8640 - migrate it to the atomic variants and delete the non-atomic drm_bridge_chain functions. There was only one user of drm_bridge_chain_mode_fixup in mediatk. The use in the mediatek driver was wrong and with the single user gone we could also delete this function. Added a few todo items. Next step is to migrate the easy bridge drivers to use the atomic variants of drm_bridge_funcs operations. The easy ones are the drivers wihtout mode_set or mode_fixup. I have something typed up already, but wanted feedback on this patchset before sending out additional patches. v2: v2 have been long in the coming as I wanted to wait until I started to have some spare time for linux stuff again, and thus time to address any comments timely. - Added Maxime's r-b (from old thread, so using old mail address [1]) - Fixed several small issues in patch 3 that introduces a new helper - Added a few more folks on cc in hope to see some testing Sam [1] https://lore.kernel.org/dri-devel/20210722062246.2512666-1-sam@ravnborg.org/ Sam Ravnborg (7): drm/bridge: ps8640: Use atomic variants of drm_bridge_funcs drm/bridge: Drop unused drm_bridge_chain functions drm/bridge: Add drm_atomic_get_new_crtc_for_bridge() helper drm/bridge: lontium-lt9611: Use atomic variants of drm_bridge_funcs drm/mediatek: Drop chain_mode_fixup call in mode_valid() drm/bridge: Drop drm_bridge_chain_mode_fixup drm/todo: Add bridge related todo items Documentation/gpu/todo.rst | 49 +++++++++++ drivers/gpu/drm/bridge/lontium-lt9611.c | 75 +++++++--------- drivers/gpu/drm/bridge/parade-ps8640.c | 14 +-- drivers/gpu/drm/drm_atomic.c | 42 +++++++++ drivers/gpu/drm/drm_bridge.c | 147 -------------------------------- drivers/gpu/drm/mediatek/mtk_hdmi.c | 11 --- include/drm/drm_atomic.h | 3 + include/drm/drm_bridge.h | 31 ------- 8 files changed, 135 insertions(+), 237 deletions(-)
