2018-07-31drm/radeon: Replace ttm_bo_unref with ttm_bo_putThomas Zimmermann1-3/+2
The function ttm_bo_put releases a reference to a TTM buffer object. The function's name is more aligned to the Linux kernel convention of naming ref-counting function _get and _put. A call to ttm_bo_unref takes the address of the TTM BO object's pointer and clears the pointer's value to NULL. This is not necessary in most cases and sometimes even worked around by the calling code. A call to ttm_bo_put only releases the reference without clearing the pointer. The current behaviour of cleaning the pointer is kept in the calling code, but should be removed if not required in a later patch.

2018-07-31drm/scheduler: stop setting rq to NULLChristian König1-27/+8
We removed the redundancy of having an extra scheduler field, so we can't set the rq to NULL any more or otherwise won't know which scheduler to use for the cleanup. Just remove the entity from the scheduling list instead.

2018-07-31drm/amdgpu: always recreate bo_listChristian König3-15/+12
The bo_list handle is allocated by OP_CREATE, so in OP_UPDATE here we just re-create the bo_list object and replace the handle. This way we don't need locking to protect the bo_list because it's always re-created when changed.

2018-07-27drm/ttm: Merge hugepage attr changes in ttm_dma_page_put. (v2)Bas Nieuwenhuizen1-7/+4
Every set_pages_array_wb call resulted in cross-core interrupts and TLB flushes. Merge more of them for less overhead. This reduces the time needed to free a 1.6 GiB GTT WC buffer as part of Vulkan CTS from ~2 sec to < 0.25 sec. (Allocation still takes more than 2 sec though) (v2): use set_pages_wb instead of set_memory_wb.
