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

2015-03-04T23:04:39+00:00

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.

drm/ttm: kill fence_lock

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.

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.

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.

drm/ttm: fix handling of TTM_PL_FLAG_TOPDOWN v2

2014-07-08T01:15:58+00:00

bo->mem.placement is not initialized when ttm_bo_man_get_node is called,
so the flag had no effect at all.

v2: change nouveau and vmwgfx as well

drm/ttm: remove declaration of ttm_tt_cache_flush

2014-07-07T22:29:57+00:00

ttm_tt_cache_flush's implementation was removed in 2009 by commit
c9c97b8c, but its declaration has been hiding in ttm_bo_driver.h since
then.

It has been surviving in the dark for too long now ; give it the mercy
blow.

drm: init TTM dev_mapping in ttm_bo_device_init()

2014-03-16T11:23:42+00:00

With dev->anon_inode we have a global address_space ready for operation
right from the beginning. Therefore, there is no need to do a delayed
setup with TTM. Instead, set dev_mapping during initialization in
ttm_bo_device_init() and remove any "if (dev_mapping)" conditions.
