[PATCH v5 0/5] mm, drm/ttm, drm/xe: Avoid reclaim/eviction loops under fragmentation

[PATCH v5 0/5] mm, drm/ttm, drm/xe: Avoid reclaim/eviction loops under fragmentation

[Matthew Brost]

Alternative approach to [1].

TTM allocations at higher orders can drive Xe into a pathological
reclaim loop when memory is fragmented:

kswapd → shrinker → eviction → rebind (exec ioctl) → repeat

In this state, reclaim is triggered despite substantial free memory,
but fails to produce contiguous higher-order pages. The Xe shrinker then
evicts active buffer objects, increasing faulting and rebind activity
and further feeding the loop. The result is high CPU overhead and poor
GPU forward progress.

This issue was first reported in [1] and independently observed
internally and by Google.

A simple reproducer is:

- Boot an iGPU system with mem=8G
- Launch 10 Chrome tabs running the WebGL aquarium demo
- Configure each tab with ~5k fish

Under this workload, ftrace shows a continuous loop of:

xe_shrinker_scan (kswapd)
xe_vma_rebind_exec

Performance degrades significantly, with each tab dropping to ~2 FPS on
PTL (Ubuntu 24.04).

At the same time, /proc/buddyinfo shows substantial free memory but no
higher-order availability. For example, the Normal zone:

Count: 4063 4595 3455 3400 3139 2762 2293 1655 643 0 0

This corresponds to ~2.8GB free memory, but no order-9 (2MB) blocks,
indicating severe fragmentation.

This series addresses the issue in three layers:

MM: Introduce an opportunistic_compaction hint in shrink_control.
kswapd folds the gfp flags of its wakers into a per-pgdat tri-state
(see enum kswapd_opportunistic_compaction_type) and forwards it to
shrinkers. The hint is set when every waker for a kswapd run is a
failable high-order allocation (__GFP_NORETRY or __GFP_RETRY_MAYFAIL,
without __GFP_NOFAIL) — i.e. callers that would rather see the
allocation fail than have working sets torn down to satisfy it. Any
order-0 or non-failable waker clears the hint for that run, so normal
memory pressure is unaffected.

TTM: Restrict direct reclaim to beneficial_order. Larger allocations
use __GFP_NORETRY so they fail fast (and feed the opportunistic hint
above) rather than synchronously triggering reclaim that is unlikely
to produce a contiguous higher-order block.

Xe: Consume shrink_control::opportunistic_compaction in the Xe
shrinker. When the hint is set for a high-order pass, the shrinker
skips advertising and performing TTM backup work — which operates at
native page order and would not help compaction — and avoids tearing
down active GPU working sets. Order-0 and non-opportunistic reclaim
behaviour is unchanged, so the shrinker still participates fully
under genuine memory pressure.

With these changes, the reclaim/eviction loop is eliminated. The same
workload improves to ~10 FPS per tab (Ubuntu 24.04) or ~15 FPS per tab
(Ubuntu 24.10), and kswapd activity subsides.

Buddyinfo after applying this series shows restored higher-order
availability:

Count: 8526 7067 3092 1959 1292 660 194 28 20 13 1

v2:
 - Layer with core MM / TTM helpers (Thomas)
v4:
 - Fix build (CI)
v5:
 - Use shrinker based heurstics (Dave Chinner, Thomas's GFP idea)
 - Rename lazy_compaction → opportunistic_compaction

[PATCH v5 1/5] mm: Wire up order in shrink_control

[Matthew Brost]

Pass the allocation order through shrink_control so shrinkers have
visibility into the order that triggered reclaim.

This allows shrinkers to implement better heuristics, such as detecting
high-order allocation pressure or fragmentation and avoiding eviction
of working sets when reclaim is invoked from kswapd.

[PATCH v5 2/5] mm: Introduce opportunistic_compaction concept to vmscan and shrinkers

[Matthew Brost]

High-order allocations using __GFP_NORETRY or __GFP_RETRY_MAYFAIL
are often opportunistic attempts to satisfy fragmentation-sensitive
allocations rather than indications of severe memory pressure. In these
cases, kswapd reclaim may invoke shrinkers that aggressively destroy
working sets even though reclaim is unlikely to materially improve the
allocation outcome.

Some shrinkers manage expensive backing or migration operations where
reclaim can result in substantial working set disruption despite the
system having sufficient free memory overall. This is particularly
visible in fragmentation-heavy workloads where reclaim repeatedly tears
down active state while kswapd attempts to satisfy higher-order
allocations.

Introduce an opportunistic_compaction hint in shrink_control that allows
kswapd to communicate when reclaim originates from a high-order
allocation context that may be fragmentation driven rather than true
memory pressure. Shrinkers may use this hint to avoid destructive
working set reclaim while still participating normally during order-0
or stronger reclaim conditions.

The hint is propagated through shrink_slab() and derived from
high-order kswapd wakeups associated with non-failing allocation
contexts.

No functional changes are introduced for existing shrinkers.

[PATCH v5 3/5] drm/ttm: Issue direct reclaim at beneficial_order

[Matthew Brost]

Triggering kswap at an order higher than beneficial_order makes little
sense, as the driver has already indicated the optimal order at which
reclaim is effective. Similarly, issuing direct reclaim or triggering
kswap at a lower order than beneficial_order is ineffective, since the
driver does not benefit from reclaiming lower-order pages.

As a result, direct reclaim should only be issued with __GFP_NORETRY at
exactly beneficial_order, or as a fallback, direct reclaim without
__GFP_NORETRY at order 0 when failure is not an option.

[PATCH v5 4/5] drm/xe: Set TTM device beneficial_order to 9 (2M)

[Matthew Brost]

Set the TTM device beneficial_order to 9 (2M), which is the sweet
spot for Xe when attempting reclaim on system memory BOs, as it matches
the large GPU page size. This ensures reclaim is attempted at the most
effective order for the driver.

[PATCH v5 5/5] drm/xe: Make use of shrink_control::opportunistic_compaction hint

[Matthew Brost]

Xe/TTM backup reclaim can be extremely expensive under fragmentation
pressure as reclaim may migrate or destroy actively used GPU working
sets despite the system still having substantial free memory available.

Under high-order opportunistic reclaim, repeatedly backing up GPU
memory can lead to reclaim/rebind ping-pong behavior where active GPU
working sets are continuously torn down and reconstructed without
materially improving allocation success.

Use the new shrink_control::opportunistic_compaction hint to avoid Xe
backup reclaim during fragmentation-driven high-order reclaim attempts.
In this mode the shrinker skips advertising backup-backed reclaimable
memory and avoids initiating backup operations entirely.

Order-0 and non-opportunistic reclaim behavior remain unchanged, so
Xe backup reclaim still participates normally during genuine memory
pressure.
