    drm/vmwgfx: Assign eviction priorities to resources · 4251fa5f
    Thomas Hellstrom authored
    TTM provides a means to assign eviction priorities to buffer object. This
    means that all buffer objects with a lower priority will be evicted first
    on memory pressure.
    Use this to make sure surfaces and in particular non-dirty surfaces are
    evicted first. Evicting in particular shaders, cotables and contexts imply
    a significant performance hit on vmwgfx, so make sure these resources are
    evicted last.
    Some buffer objects are sub-allocated in user-space which means we can have
    many resources attached to a single buffer object or resource. In that case
    the buffer object is given the highest priority of the attached resources.
