drm/amdgpu: keep the MMU lock until the update ends v4

2017-09-12T18:27:56+00:00

This is quite controversial because it adds another lock which is held during
page table updates, but I don't see much other option.

v2: allow multiple updates to be in flight at the same time
v3: simplify the patch, take the read side only once
v4: correctly fix rebase conflict

drm/amdgpu: stop reserving the BO in the MMU callback v3

2017-09-12T18:26:37+00:00

Instead take the callback lock during the final parts of CS.

This should solve the last remaining locking order problems with BO reservations.

v2: rebase, make dummy functions static inline
v3: add one more missing inline and comments

drm/amdgpu: use a rw_semaphore for MMU notifiers

drm/amdgpu: move userptr BOs to CPU domain during CS v2

2017-09-12T18:24:18+00:00

Instead of moving them in the MMU notifier move them during CS.

v2: still mark pages as accessed/dirty

lib/interval_tree: fast overlap detection

2017-09-09T01:26:49+00:00

Allow interval trees to quickly check for overlaps to avoid unnecesary
tree lookups in interval_tree_iter_first().

As of this patch, all interval tree flavors will require using a
'rb_root_cached' such that we can have the leftmost node easily
available.  While most users will make use of this feature, those with
special functions (in addition to the generic insert, delete, search
calls) will avoid using the cached option as they can do funky things
with insertions -- for example, vma_interval_tree_insert_after().

drm/amdgpu: update to new mmu_notifier semantic

2017-08-31T23:12:59+00:00

Calls to mmu_notifier_invalidate_page() were replaced by calls to
mmu_notifier_invalidate_range() and are now bracketed by calls to
mmu_notifier_invalidate_range_start()/end()

Remove now useless invalidate_page callback.

drm/amdgpu: Use list_del_init in amdgpu_mn_unregister

2017-08-02T18:29:58+00:00

Otherwise bo->shadow_list (which is aliased by bo->mn_list) will not
appear empty in amdgpu_ttm_bo_destroy and cause an oops when freeing
former userptr BOs.

drm/amdgpu: use a 64bit interval tree for VM management v2

2017-04-04T17:40:32+00:00

This only makes a difference for 32-bit systems. The idea is to have a
fixed virtual address space size with 4-level page tables and to
minimize differences between 32 and 64-bit systems.

v2: Update commit message.
