drm/ttm: merge ttm_bo_api.h and ttm_bo_driver.h v2

2022-12-06T11:54:14Z

Merge and cleanup the two headers into a single description of the object API. Also move all the documentation to the implementation and drop unnecessary includes from the header.

drm/ttm: remove superflous extern attribute from funcs

drm/ttm: always keep BOs on the LRU

2019-10-25T09:40:50Z

This allows blocking for BOs to become available in the memory management. Amdgpu is doing this for quite a while now during CS. Now apply the new behavior to all drivers using TTM. Signed-off-by: Christian König Acked-by: Thomas Hellstrom Link: https://patchwork.freedesktop.org/patch/332878/

drm/ttm: Make LRU removal optional v2

2019-05-31T15:39:34Z

We are already doing this for DMA-buf imports and also for amdgpu VM BOs for quite a while now. If this doesn't run into any problems we are probably going to stop removing BOs from the LRU altogether. v2: drop BUG_ON from ttm_bo_add_to_lru Signed-off-by: Christian König Reviewed-by: Chunming Zhou Tested-by: Pierre-Eric Pelloux-Prayer Signed-off-by: Alex Deucher

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

2017-05-16T15:17:16Z

For the C file, include instead of relative path from include/drm. For headers in include/drm/ttm, simplify the with "*.h". This allows us to remove the -Iinclude/drm compiler flag from drivers/gpu/drm/ttm/Makefile (and from other drivers' Makefiles).

dma-buf: Rename struct fence to dma_fence

2016-10-25T12:40:39Z

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. Since then the patch has grown a bit as usage increases, so hopefully it remains a good thing!
