2014-07-04	drm/vmwgfx: Fix compat shader namespace	Thomas Hellstrom	1	-10/+28
	Contrary to the host-backed shader interface that has a per-context name-space for shaders, the compat shader namespace was per client (or rather, per file). Fix this so that the compat shader namespace is per context, and at the same time, make command buffer managed context resource management generic.

2014-04-03	drm/vmwgfx: Fix query buffer locking order violation	Thomas Hellstrom	1	-1/+1
	The query buffers were reserved while holding the binding mutex, which caused a circular locking dependency. Cc: stable@vger.kernel.org Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Brian Paul <brianp@vmware.com>
2014-03-28	drm/vmwgfx: Use a per-device semaphore for reservation protection	Thomas Hellstrom	1	-3/+2
	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.

2014-02-05	drm/vmwgfx: Reemit context bindings when necessary v2	Thomas Hellstrom	1	-21/+123
	When a context is first referenced in the command stream, make sure that all scrubbed (as a result of eviction) bindings are re-emitted. Also make sure that all bound resources are put on the resource validate list. This is needed for legacy emulation, since legacy user-space drivers will typically not re-emit shader bindings. It also removes the requirement for user-space drivers to re-emit render-target- and texture bindings. Makes suspend and hibernate now also work with legacy user-space drivers on guest-backed devices. v2: Don't rebind on legacy devices.
