drm/ttm: fix eviction valuable range check.

2020-11-05T10:51:52+00:00

commit fea456d82c19d201c21313864105876deabe148b upstream. This was adding size to start, but pfn and start are in pages, so it should be using num_pages. Not sure this fixes anything in the real world, just noticed it during refactoring.

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). Reviewed-by: Christian König Signed-off-by: Dave Airlie Link: https://patchwork.freedesktop.org/patch/msgid/20200728040003.20398-1-airlied@gmail.com

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.
