[PATCH 2/4] drm/ttm: replace busy placement with flags v3

[Christian König]

From: Somalapuram Amaranath <Amaranath.Somalapuram@amd.com>

Instead of a list of separate busy placement add flags which indicate
that a placement should only be used when there is room or if we need to
evict.

v2: add missing TTM_PL_FLAG_IDLE for i915
v3: fix auto build test ERROR on drm-tip/drm-tip

[PATCH 3/4] drm/ttm: improve idle/busy handling

[Christian König]

Previously we would never try to move a BO into the preferred placements when
it ever landed in a busy placement since those were considered compatible.

Rework the whole handling and finally unify the idle and busy handling.
ttm_bo_validate() is now responsible to try idle placement first and then use
the busy placement if that didn't worked.

Drawback is that we now always try the idle placement first for each
validation which might cause some additional CPU overhead on overcommit.

[PATCH 4/4] drm/amdgpu: use GTT only as fallback for VRAM|GTT

[Christian König]

Try to fill up VRAM as well by setting the busy flag on GTT allocations.

This fixes the issue that when VRAM was evacuated for suspend it's never
filled up again unless the application is restarted.
