2020-09-17drm/ttm: remove superflous extern attribute from funcsChristian König1-11/+8
Extern is the default attribute for functions anyway. Signed-off-by: Christian König <[email protected]> Reviewed-by: Daniel Vetter <[email protected]> Link: https://patchwork.freedesktop.org/patch/390972/
2019-10-25drm/ttm: always keep BOs on the LRUChristian König1-1/+1
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.

2019-05-31drm/ttm: Make LRU removal optional v2Christian König1-1/+2
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 <[email protected]> Reviewed-by: Chunming Zhou <[email protected]> Tested-by: Pierre-Eric Pelloux-Prayer <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2017-05-16drm/ttm: fix include notation and remove -Iinclude/drm flagMasahiro Yamada1-1/+2
For the C file, include <drm/*.h> instead of relative path from include/drm. For headers in include/drm/ttm, simplify the <tty/*.h> with "*.h". This allows us to remove the -Iinclude/drm compiler flag from drivers/gpu/drm/ttm/Makefile (and from other drivers' Makefiles).

2016-10-25dma-buf: Rename struct fence to dma_fenceChris Wilson1-1/+1
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!

2014-12-03drm/ttm: optionally move duplicates to a separate listChristian König1-1/+8
This patch adds an optional list_head parameter to ttm_eu_reserve_buffers. If specified duplicates in the execbuf list are no longer reported as errors, but moved to this list instead.

2014-09-01drm/ttm: kill off some members to ttm_validate_bufferMaarten Lankhorst1-3/+0
This reorders the list to keep track of what buffers are reserved, so previous members are always unreserved. This gets rid of some bookkeeping that's no longer needed, while simplifying the code some. Signed-off-by: Maarten Lankhorst <[email protected]>
2014-09-01drm/ttm: add interruptible parameter to ttm_eu_reserve_buffersMaarten Lankhorst1-4/+5

2013-11-18drm/ttm: Allow execbuf util reserves without ticketThomas Hellstrom1-1/+2
If no reservation ticket is given to the execbuf reservation utilities, try reservation with non-blocking semantics. This is intended for eviction paths that use the execbuf reservation utilities for convenience rather than for deadlock avoidance.

2013-06-28drm/ttm: convert to the reservation apiMaarten Lankhorst1-1/+0
Now that the code is compatible in semantics, flip the switch. Use ww_mutex instead of the homegrown implementation. ww_mutex uses -EDEADLK to signal that the caller has to back off, and -EALREADY to indicate this buffer is already held by the caller. ttm used -EAGAIN and -EDEADLK for those, respectively. So some changes were needed to handle this correctly.

2013-06-28drm/ttm: make ttm reservation calls behave like reservation callsMaarten Lankhorst1-3/+10
This commit converts the source of the val_seq counter to the ww_mutex api. The reservation objects are converted later, because there is still a lockdep splat in nouveau that has to resolved first.
