drm/ttm: Allow execbuf util reserves without ticket

2013-11-18T08:38:52Z

If no reservation ticket is given to the execbuf reservation utilities, try reservation with non-blocking semantics. This is intended for eviction paths that use the execbuf reservation utilities for convenience rather than for deadlock avoidance. Signed-off-by: Thomas Hellstrom Reviewed-by: Jakob Bornecrantz

drm/ttm: convert to the reservation api

2013-06-28T02:04:01Z

Now that the code is compatible in semantics, flip the switch. Use ww_mutex instead of the homegrown implementation. ww_mutex uses -EDEADLK to signal that the caller has to back off, and -EALREADY to indicate this buffer is already held by the caller. ttm used -EAGAIN and -EDEADLK for those, respectively. So some changes were needed to handle this correctly. Signed-off-by: Maarten Lankhorst Reviewed-by: Jerome Glisse Signed-off-by: Dave Airlie

drm/ttm: make ttm reservation calls behave like reservation calls

2013-06-28T02:02:20Z

This commit converts the source of the val_seq counter to the ww_mutex api. The reservation objects are converted later, because there is still a lockdep splat in nouveau that has to resolved first. Signed-off-by: Maarten Lankhorst Reviewed-by: Jerome Glisse Signed-off-by: Dave Airlie

drm/ttm/vmwgfx: Have TTM manage the validation sequence.

2010-11-22T03:25:21Z

Rather than having the driver supply the validation sequence, leave that responsibility to TTM. This saves some confusion and a function argument. Signed-off-by: Thomas Hellstrom Signed-off-by: Dave Airlie

drm/ttm: Improved fencing of buffer object lists

2010-11-22T03:25:20Z

drm/ttm: Add a bo list reserve fastpath (v2)

2010-11-22T03:24:40Z

Makes it possible to reserve a list of buffer objects with a single spin lock / unlock if there is no contention. Should improve cpu usage on SMP kernels. v2: Initialize private list members on reserve and don't call ttm_bo_list_ref_sub() with zero put_count.
