drm/ttm, drm/vmwgfx: Relax permission checking when opening surfaces

2017-04-22T05:14:59+00:00

commit fe25deb7737ce6c0879ccf79c99fa1221d428bf2 upstream. Previously, when a surface was opened using a legacy (non prime) handle, it was verified to have been created by a client in the same master realm. Relax this so that opening is also allowed recursively if the client already has the surface open. This works around a regression in svga mesa where opening of a shared surface is used recursively to obtain surface information.

drm/ttm: Make ttm_bo_mem_compat available

2016-08-08T01:44:43+00:00

[ Upstream commit 94477bff390aa4612d2332c8abafaae0a13d6923 ] There are cases where it is desired to see if a proposed placement is compatible with a buffer object before calling ttm_bo_validate().

drm/ttm: add reservation_object as argument to ttm_bo_init

2014-09-30T12:04:00+00:00

This allows importing reservation objects from dma-bufs. Signed-off-by: Maarten Lankhorst

drm/ttm: allow fence to be added as shared

2014-09-11T14:46:00+00:00

This patch adds a new flag to the ttm_validate_buffer list to add the fence as shared to the reservation object. Signed-off-by: Christian König Signed-off-by: Alex Deucher

drm/ttm: flip the switch, and convert to dma_fence

drm/ttm: kill off some members to ttm_validate_buffer

2014-09-01T08:18:03+00:00

This reorders the list to keep track of what buffers are reserved, so previous members are always unreserved. This gets rid of some bookkeeping that's no longer needed, while simplifying the code some. Signed-off-by: Maarten Lankhorst

drm/ttm: add interruptible parameter to ttm_eu_reserve_buffers

2014-09-01T08:16:43+00:00

It seems some drivers really want this as a parameter, like vmwgfx. Signed-off-by: Maarten Lankhorst

drm/ttm: kill fence_lock

2014-09-01T08:16:43+00:00

No users are left, kill it off! :D Conversion to the reservation api is next on the list, after that the functionality can be restored with rcu. Signed-off-by: Maarten Lankhorst

drm/ttm: move fpfn and lpfn into each placement v2

2014-08-27T11:16:04+00:00

This allows us to more fine grained specify where to place the buffer object. v2: rebased on drm-next, add bochs changes as well Signed-off-by: Christian König Reviewed-by: Alex Deucher

drm/ttm: expose CPU address of DMA-allocated pages

2014-08-09T15:08:03+00:00

Pages allocated using the DMA API have a coherent memory mapping. Make this mapping visible to drivers so they can decide to use it instead of creating their own redundant one. Signed-off-by: Alexandre Courbot Acked-by: David Airlie Signed-off-by: Ben Skeggs
