- Summary
- Revert "drm/xe: Skip exec queue schedule toggle if queue is idle during suspend"
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
Revert "drm/xe: Skip exec queue schedule toggle if queue is idle during suspend"
This reverts commit 8533051ce92015e9cc6f75e0d52119b9d91610b6.
The idle-skip optimization bypasses GuC suspend, so the GPU may not perform the context switch that flushes TLB entries for invalidated userptr VMAs. In LR/preempt-fence VM mode, this can lead to missed TLB invalidation and page faults during userptr invalidation tests.
Restore unconditional schedule toggling on suspend so the context-switch TLB flush is always performed.
This optimization will be reintroduced with a fix that does not skip suspend in LR/preempt-fence VM mode.
(cherry picked from commit 6a1e7934d9a6cf46aecae00a99c2603d1295e170)
