drm/ttm: device address space != CPU address space

2015-03-04T23:04:39Z

We need to store device offsets in 64 bit as the device address space may be larger than the CPU's. Fixes GPU init failures on radeons with 4GB or more of vram on 32 bit kernels. We put vram at the start of the GPU's address space so the gart aperture starts at 4 GB causing all GPU addresses in the gart aperture to get truncated. bug: https://bugs.freedesktop.org/show_bug.cgi?id=89072 [airlied: fix warning on nouveau build] Signed-off-by: Alex Deucher Cc: thellstrom@vmware.com Acked-by: Thomas Hellstrom Signed-off-by: Dave Airlie

drm/ttm: optionally move duplicates to a separate list

2014-12-03T23:26:52Z

This patch adds an optional list_head parameter to ttm_eu_reserve_buffers. If specified duplicates in the execbuf list are no longer reported as errors, but moved to this list instead. Reviewed-by: Thomas Hellstrom Signed-off-by: Christian König Signed-off-by: Alex Deucher

drm/ttm: add reservation_object as argument to ttm_bo_init

2014-09-30T12:04:00Z

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

drm/ttm: allow fence to be added as shared

2014-09-11T14:46:00Z

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

2014-09-01T08:18:03Z

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

2014-09-01T08:16:43Z

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

drm/ttm: kill fence_lock

2014-09-01T08:16:43Z

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/ttm: expose CPU address of DMA-allocated pages

2014-08-09T15:08:03Z

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
