drm/ttm: Be consistent on ttm_bo_init() failures

2010-11-10T01:52:19+00:00

Call destroy() on _all_ ttm_bo_init() failures, and make sure that
behavior is documented in the function description.

We need the unlocked variant for the new codepath introduced to fix the
race condition in master recently.

drm/ttm: Fix two race conditions + fix busy codepaths

2010-10-05T23:04:43+00:00

This fixes a race pointed out by Dave Airlie where we don't take a buffer
object about to be destroyed off the LRU lists properly. It also fixes a rare
case where a buffer object could be destroyed in the middle of an
accelerated eviction.

The patch also adds a utility function that can be used to prematurely
release GPU memory space usage of an object waiting to be destroyed.
For example during eviction or swapout.

The above mentioned commit didn't queue the buffer on the delayed destroy
list under some rare circumstances. It also didn't completely honor the
remove_all parameter.

drm/ttm: restructure to allow driver to plug in alternate memory manager

2010-10-05T00:01:20+00:00

Nouveau will need this on GeForce 8 and up to account for the GPU
reordering physical VRAM for some memory types.

drm/ttm: introduce utility function to free an allocated memory node

2010-10-05T00:00:34+00:00

Existing core code/drivers call drm_mm_put_block on ttm_mem_reg.mm_node
directly.  Future patches will modify TTM behaviour in such a way that
ttm_mem_reg.mm_node doesn't necessarily belong to drm_mm.

drm: move ttm global code to core drm

2010-08-03T23:46:06+00:00

I wrote this for the prime sharing work, but I also noticed other external
non-upstream drivers from a large company carrying a similiar patch, so I
may as well ship it in master.

drm/ttm: Allocate the page pool manager in the heap.

2010-07-07T02:14:11+00:00

Repeated ttm_page_alloc_init/fini fails noisily because the pool
manager kobj isn't zeroed out between uses (we could do just that but
statically allocated kobjects are generally considered a bad thing).
Move it to kzalloc'ed memory.

Note that this patch drops the refcounting behavior of the pool
allocator init/fini functions: it would have led to a race condition
in its current form, and anyway it was never exploited.

This fixes a regression with reloading kms modules at runtime, since
page allocator was introduced.
