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.

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.
