      drm/ttm: callback move_notify any time bo placement change v4 · dc97b340
      由 Jerome Glisse 提交于 
      Previously we were calling back move_notify in error path when the
bo is returned to it's original position or when destroy the bo.
When destroying the bo set the new mem placement as NULL when calling
back in the driver.

Updating nouveau to deal with NULL placement properly.

v2: reserve the object before calling move_notify in bo destroy path
    at that point ttm should be the only piece of code interacting
    with the object so atomic_set is safe here.
v3: callback move notify only once the bo is in its new position
    call move notify want swaping out the buffer
v4:- don't call move_notify when swapin out bo, assume driver should
     do what is appropriate in swap notify
   - move move_notify call back to ttm_bo_cleanup_memtype_use for
     destroy path

      drm/ttm: simplify memory accounting for ttm user v2 · 57de4ba9
      由 Jerome Glisse 提交于 
      Provide helper function to compute the kernel memory size needed
for each buffer object. Move all the accounting inside ttm, simplifying
driver and avoiding code duplication accross them.

v2 fix accounting of ghost object, one would have thought that i
   would have run into the issue since a longtime but it seems
   ghost object are rare when you have plenty of vram ;)

      drm/ttm: isolate dma data from ttm_tt V4 · 8e7e7052
      由 Jerome Glisse 提交于 
      Move dma data to a superset ttm_dma_tt structure which herit
from ttm_tt. This allow driver that don't use dma functionalities
to not have to waste memory for it.

V2 Rebase on top of no memory account changes (where/when is my
   delorean when i need it ?)
V3 Make sure page list is initialized empty
V4 typo/syntax fixes

      drm/nouveau: enable the ttm dma pool when swiotlb is active V3 · 3230cfc3
      由 Konrad Rzeszutek Wilk 提交于 
      If the card is capable of more than 32-bit, then use the default
TTM page pool code which allocates from anywhere in the memory.

Note: If the 'ttm.no_dma' parameter is set, the override is ignored
and the default TTM pool is used.

V2 use pci_set_consistent_dma_mask
V3 Rebase on top of no memory account changes (where/when is my
   delorean when i need it ?)
