drm/vmwgfx: get rid of different types of fence_flags entirely

2014-09-02T14:41:50Z

Only one type was ever used. This is needed to simplify the fence support in the next commit. Signed-off-by: Maarten Lankhorst

drm/ttm: kill fence_lock

2014-09-01T08:16:43Z

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

2014-08-27T11:16:04Z

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/vmwgfx: Hook up MOBs to TTM as a separate memory type

2014-01-17T06:52:21Z

To bind a buffer object as a MOB, just validate it as a MOB memory type. We are reusing the GMRID manager, although we create a new instance of it to manage MOB ids and tomake sure we don't exceed the maximum amount of MOB pages. Signed-off-by: Thomas Hellstrom Reviewed-by: Brian Paul

drm/vmwgfx: Add MOB management

2014-01-17T06:52:19Z

Implement MOB setup, binding and unbinding, but don't hook up to TTM yet. Signed-off-by: Thomas Hellstrom Reviewed-by: Brian Paul Reviewed-by: Zack Rusin

drivers: gpu: Mark functions as static in vmwgfx_buffer.c

2014-01-08T12:44:26Z

Mark functions as static because they are not used outside the file drm/vmwgfx/vmwgfx_buffer.c. This eliminates the following warnings in drm/vmwgfx/vmwgfx_buffer.c: drivers/gpu/drm/vmwgfx/vmwgfx_buffer.c:520:16: warning: no previous prototype for ‘vmw_ttm_tt_create’ [-Wmissing-prototypes] drivers/gpu/drm/vmwgfx/vmwgfx_buffer.c:549:5: warning: no previous prototype for ‘vmw_invalidate_caches’ [-Wmissing-prototypes] drivers/gpu/drm/vmwgfx/vmwgfx_buffer.c:554:5: warning: no previous prototype for ‘vmw_init_mem_type’ [-Wmissing-prototypes] drivers/gpu/drm/vmwgfx/vmwgfx_buffer.c:592:6: warning: no previous prototype for ‘vmw_evict_flags’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria Reviewed-by: Josh Triplett Reviewed-by: Jakob Bornecrantz

drm/vmwgfx: Fix dma buffer memory size accounting

2013-12-04T20:03:56Z

Also request kernel ttm_buffer objects for buffer objects that obviously aren't visible to user-space, and save some device address space. The accounting was broken in a couple of ways: 1) We did not differentiate between user dma buffers and kernel dma buffers. 2) The ttm_bo_acc_size function is broken in that it a) Doesn't take into account the size of the optional dma address array, b) Doesn't take into account the fact that drivers typically embed the ttm_tt structure. This needs to be fixed in ttm, but meanwhile provide a vmwgfx-specific function to do the job. Signed-off-by: Thomas Hellstrom Reviewed-by: Jakob Bornecrantz

drm/vmwgfx: Use the linux DMA api to get valid device addresses of pages

2013-11-06T11:57:16Z

The code handles three different cases: 1) physical page addresses. The ttm page array is used. 2) DMA subsystem addresses. A scatter-gather list is used. 3) Coherent pages. The ttm dma pool is used, together with the dma_ttm array os dma_addr_t Signed-off-by: Thomas Hellstrom Reviewed-by: Jakob Bornecrantz
