drm/ttm: revert "drm/ttm: make TT creation purely optional v3"

2020-08-12T03:26:28+00:00

This reverts commit 2ddef17678bc2ea1d20517dd2b4ed4aa967ffa8b.

As it turned out VMWGFX needs a much wider audit to fix this.

drm/ttm: fix offset in VMAs with a pg_offs in ttm_bo_vm_access

2020-07-30T11:55:28+00:00

VMAs with a pg_offs that's offset from the start of the vma_node need
to adjust the offset within the BO accordingly. This matches the
offset calculation in ttm_bo_vm_fault_reserved.

drm/ttm/nouveau: don't call tt destroy callback on alloc failure.

2020-07-29T00:06:38+00:00

This is confusing, and from my reading of all the drivers only
nouveau got this right.

Just make the API act under driver control of it's own allocation
failing, and don't call destroy, if the page table fails to
create there is nothing to cleanup here.

(I'm willing to believe I've missed something here, so please
review deeply).

drm/ttm: ttm_bo_swapout_all doesn't use it's argument.

2020-07-29T00:01:23+00:00

Just drop the argument from this.

This does ask the question if this is the function vmwgfx
should be using or should it be doing an evict all like
the other drivers.

drm/ttm: make ttm_tt unbind function return void.

2020-07-28T23:43:06+00:00

The return value just led to BUG_ON, I think if a driver wants
to BUG_ON here it can do it itself. (don't BUG_ON).

drm/ttm: remove TTM_MEMTYPE_FLAG_CMA

2020-07-21T14:21:43+00:00

The original intention was to avoid CPU page table unmaps
when BOs move between the GTT and SYSTEM domain.

The problem is that this never correctly handled changes
in the caching attributes or backing pages.

Just drop this for now and simply unmap the CPU page
tables in all cases.

drm/ttm: cleanup coding style and implementation.

Only functional change is to always keep io_reserved_count up to date
for debugging even when it is not used otherwise.
