<title>drm/ttm: Handle cgroup based eviction in TTM</title>

<content type='text'>
cgroup resource allocation has to be handled in TTM, so -EAGAIN from
cgroups can be converted into -ENOSPC, and the limitcg can be properly
evicted in ttm code.

When hitting a resource limit through -EAGAIN, the cgroup for which the
limit is hit is also returned. This allows eviction to delete only from
cgroups which are a subgroup of the current cgroup.

The returned CSS is used to determine if eviction is valuable for a
given resource, and allows TTM to only target specific resources to
lower memory usage.

<title>drm/ttm: Move pinned objects off LRU lists when pinning</title>

<id>4cce1373c17fc527b78ad22ddca3027042aea3a0</id>
<content type='text'>
The ttm_bo_pin() and ttm_bo_unpin() functions weren't moving their
resources off the LRU list to the unevictable list.

Make sure that happens so that pinned objects don't accidently linger
on the LRU lists, and also make sure to move them back once they
are unpinned.

v2:
- Removing from a bulk move must be done with the pin-count still zero.
v3:
- ttm_resource_move_to_lru_tail must be done after pinning with a non-
  NULL resource (Intel CI).
v6:
- Use a TAB instead of space (checkpatch.pl error).

v2:
- Removing from a bulk move must be done with the pin-count still zero.
v3:
- ttm_resource_move_to_lru_tail must be done after pinning with a non-
  NULL resource (Intel CI).
v6:
- Use a TAB instead of space (checkpatch.pl error).

<title>drm/ttm: Move swapped objects off the manager's LRU list</title>

<id>fc5d96670eb2540d2572a14351e82ffe45d5ac11</id>
<content type='text'>
Resources of swapped objects remains on the TTM_PL_SYSTEM manager's
LRU list, which is bad for the LRU walk efficiency.

Rename the device-wide "pinned" list to "unevictable" and move
also resources of swapped-out objects to that list.

An alternative would be to create an "UNEVICTABLE" priority to
be able to keep the pinned- and swapped objects on their
respective manager's LRU without affecting the LRU walk efficiency.

v2:
- Remove a bogus WARN_ON (Christian König)
- Update ttm_resource_[add|del] bulk move (Christian König)
- Fix TTM KUNIT tests (Intel CI)
v3:
- Check for non-NULL bo-&gt;resource in ttm_bo_populate().
v4:
- Don't move to LRU tail during swapout until the resource
  is properly swapped or there was a swapout failure.
  (Intel Ci)
- Add a newline after checkpatch check.
v5:
- Introduce ttm_resource_is_swapped() to avoid a corner-case where
  a newly created resource was considered swapped. (Intel CI)
v6:
- Move an assert.

Limiting the allocation of higher order pages to the closest NUMA node
and enabling direct memory reclaim provides not only failsafe against
situations when memory becomes too much fragmented and the allocator is
not able to satisfy the request from the local node but falls back to
remote pages (HUGEPAGE) but also offers performance improvement.
Accessing remote pages suffers due to bandwidth limitations and could be
avoided if memory becomes defragmented and in most cases without using
manual compaction. (/proc/sys/vm/compact_memory)

Note: On certain distros such as RHEL, the proactive compaction is
disabled. (https://tinyurl.com/4f32f7rs)

v2 (chk): drop __GFP_RECLAIM since that is already set by GFP_USER
