drm/ttm: Remove ttm_bo_reference and ttm_bo_unref

Export ttm_bo_get_unless_zero() to be used when looking up buffer objects that are removed from the lookup structure in the destructor. Signed-off-by: Thomas Hellstrom Reviewed-by: Sinclair Yeh Reviewed-by: Christian König

drm/ttm: add bulk move function on LRU

2018-08-27T16:11:21Z

This function allow us to bulk move a group of BOs to the tail of their LRU. The positions of group of BOs are stored on the (first, last) bulk_move_pos structure.

drm/ttm: revise ttm_bo_move_to_lru_tail to support bulk moves

2018-08-27T16:11:21Z

When move a BO to the end of LRU, it need remember the BO positions. Make sure all moved bo in between "first" and "last". And they will be bulk moving together.

drm/ttm: Introduce ttm_bo_get() and ttm_bo_put() for ref counting

2018-07-10T19:18:15Z

The TTM buffer-object interface provides ttm_bo_reference() and ttm_bo_unref() for managing reference counts. Replacing them with ttm_bo_get() and ttm_bo_put() aligns the API with conventions used throughout the Linux kernel. The implementation of ttm_bo_unref() clears the supplied pointer to NULL. This leads to workarounds where the caller saves the pointer's value before de-referencing the BO. ttm_bo_put() does not clear the supplied pointer.

drm/ttm: add bit flag TTM_OPT_FLAG_FORCE_ALLOC

2018-02-27T04:09:34Z

set TTM_OPT_FLAG_FORCE_ALLOC when we are servicing for page fault routine. for ttm_mem_global_reserve if in page fault routine, allow the gtt pages reservation always. because page fault routing already grabbed system memory and the allowance of this exception is harmless. Otherwise, it will trigger OOM killer. will be used later. v2: set the FORCE_ALLOC always v3: minor refine Signed-off-by: Roger He Reviewed-by: Christian König Signed-off-by: Alex Deucher
