2021-05-21drm/amdgpu: Add new placement for preemptible SG BOsFelix Kuehling
SG BOs such as dmabuf imports and userptr BOs do not consume system resources directly. Instead they point to resources owned elsewhere. They typically get evicted by DMABuf move notifiers of MMU notifiers. If those notifiers don't need to wait for hardware fences (i.e. the SG BOs are used in a preemptible context), then we don't need to limit them to the GTT size and we don't need TTM to evict them. Create a new placement for such preemptible SG BOs that does not impose artificial size limits and TTM evictions.

This allows us to provide fine grained asic capabilities (e.g., if a particular part is bandwidth limited, we can limit the capabilities). Proposed userspace: https://gitlab.freedesktop.org/leoliu/drm/-/commits/info_video_caps https://gitlab.freedesktop.org/leoliu/mesa/-/commits/info_video_caps - amdkfd: bump the driver version. There was a problem with reporting some RAS features on older versions of the driver. Proposed userspace: https://github.com/RadeonOpenCompute/ROCT-Thunk-Interface/commit/7cdd63475c36bb9f49bb960f90f9a8cdb7e80a21 Danvet: A bunch of conflicts all over, but it seems to compile ... I did put the call to dc_allow_idle_optimizations() on a single line since it looked a bit too jarring to be left alone.
