2016-07-01drm/vmwgfx: Check pin count before attempting to move a bufferSinclair Yeh1-3/+22
In certain scenarios, e.g. when fbdev is enabled, we can get into a situation where a vmw_framebuffer_pin() is called on a buffer that is already pinned. When this happens, ttm_bo_validate() will unintentially remove the TTM_PL_FLAG_NO_EVICT flag, thus unpinning it, and leaving no way to actually pin the buffer again. To prevent this, if a buffer is already pinned, then instead of calling ttm_bo_validate(), just make sure the proposed placement is compatible with the existing placement. Signed-off-by: Sinclair Yeh <> Reviewed-by: Thomas Hellstrom <> Cc: <> --- This is the 2nd patch in a 3-patch series to fix a console black screen issue on Ubuntu 16.04 server. This fixes a BUG_ON() condition where a pinned buffer gets accidentally put onto the LRU list.

2014-03-28drm/vmwgfx: Use a per-device semaphore for reservation protectionThomas Hellstrom1-9/+6
Don't use a per-master semaphore (ttm lock) for reservation protection, but rather a per-device semaphore. This is needed since clients connecting using render nodes aren't master aware. The ttm lock used should probably be replaced with a reader-write semaphore once the function down_xx_interruptible() is available. Signed-off-by: Thomas Hellstrom <> Reviewed-by: Brian Paul <>
2014-01-17drm/vmwgfx: Ditch the vmw_dummy_query_bo_prepare functionThomas Hellstrom1-6/+2
Combine it with vmw_dummy_query_bo_create, and also make sure we use tryreserve when reserving the bo to avoid any lockdep warnings We are sure the tryreserve will always succeed since we are the only users at that point. In addition, allow the vmw_bo_pin function to pin/unpin system memory. Signed-off-by: Thomas Hellstrom <> Reviewed-by: Jakob Bornecrantz <>

2012-12-10drm/ttm: remove no_wait_reserve, v3Maarten Lankhorst1-7/+6
All items on the lru list are always reservable, so this is a stupid thing to keep. Not only that, it is used in a way which would guarantee deadlocks if it were ever to be set to block on reserve. This is a lot of churn, but mostly because of the removal of the argument which can be nested arbitrarily deeply in many places. No change of code in this patch except removal of the no_wait_reserve argument, the previous patch removed the use of no_wait_reserve. v2: - Warn if -EBUSY is returned on reservation, all objects on the list should be reservable. Adjusted patch slightly due to conflicts. v3: - Focus on no_wait_reserve removal only. Signed-off-by: Maarten Lankhorst <> Reviewed-by: Thomas Hellstrom <> Signed-off-by: Dave Airlie <>

Refactor resource management to make it easy to hook up resources that are backed up by buffers. In particular, resources and their backing buffers can be evicted and rebound, if supported by the device. To avoid query deadlocks, the query code is also modified somewhat.

2011-10-05vmwgfx: Fix up query processingThomas Hellstrom1-0/+44
Previously, query results could be placed in any buffer object, but since we didn't allow pinned buffer objects, query results could be written when that buffer was evicted, corrupting data in other buffers. Now, require that buffers holding query results are no more than two pages large, and allow one single pinned such buffer. When the command submission code encounters query result structures in other buffers, the queries in the pinned buffer will be finished using a query barrier for the last hardware context using the buffer. Also if the command submission code detects that a new hardware context is used for queries, all queries of the previous hardware context is also flushed. Currently we use waiting for a no-op occlusion query as a query barrier for a specific context. The query buffer is also flushed and unpinned on context destructions, master drops and before scanout bo placement.
