[PATCH 0/4] drm/xe: Fix LR exec queue suspend/resume for S3/S4

[PATCH 0/4] drm/xe: Fix LR exec queue suspend/resume for S3/S4

[Thomas Hellström]

Long Running (LR) exec queues — used by compute workloads with SVM
(fault-mode) and by preempt-fence-mode — were not surviving S3/S4
suspend/resume correctly.  Four distinct problems are addressed:

1. Exec queue ops (guc_exec_queue_suspend/resume) lacked coordination
   when multiple paths (PM, mode switching, preempt fences) needed to
   hold the queue suspended simultaneously.  A suspend refcount ensures
   the GuC SUSPEND message is only sent when the first caller suspends,
   and the RESUME message only when the last caller resumes.

2. During PM suspend, guc_exec_queue_stop() banned any user exec queue
   that had a started-but-incomplete job.  For LR queues this is always
   true — their jobs are designed to run indefinitely — so every PM
   suspend permanently banned the queue.  The ban is now suppressed for
   LR VM exec queues during PM suspend or hibernation while being
   preserved for GT reset (legitimate hang detection).

3. Userspace LRC buffer objects carried XE_BO_FLAG_PINNED_LATE_RESTORE,
   deferring their VRAM restore to after xe_gt_resume().  However,
   xe_gt_resume() drives context registration, which requires valid LRC
   VRAM.  Dropping the flag moves the restore to xe_bo_restore_early(),
   a CPU/BAR copy that runs before xe_gt_resume(), fixing the ordering.

4. Fault-mode (SVM) VMs use GPU page faults to access memory.  A
   running fault-mode job can re-fault pages torn down by VRAM eviction,
   racing with the eviction.  A new xe_suspend_all_faulting_lr_jobs()
   call in the PM notifier stops all fault-mode queues and waits for GuC
   acknowledgement before eviction begins.  On resume,
   xe_resume_all_faulting_lr_jobs() mirrors the same iteration to
   re-register and resume exactly those queues.  A per-group pm_suspended
   flag (protected by mode_sem) prevents new fault-mode exec queues from
   slipping through unsuspended while PM suspend is in progress.

Note: A prerequisite revert ("Revert drm/xe: Skip exec queue schedule
toggle if queue is idle during suspend") was already sent as a separate
patch and is not included here.

[PATCH 1/4] drm/xe/guc: Add suspend refcount to exec queue ops

[Thomas Hellström]

Concurrent call sites that suspend exec queues (PM, mode switching,
preempt fences) each need to pair their own suspend/resume without
caring about other callers. Without coordination, a resume from one
path can prematurely re-enable a queue still suspended by another.

Add suspend_count to xe_guc_exec_queue. The SUSPEND message is only
sent on the 0->1 transition; the RESUME message is only sent on the
1->0 transition. Callers simply pair suspend and resume. The existing
sched.msg_lock spinlock serialises concurrent calls so neither side
needs to know about the other.

[PATCH 2/4] drm/xe/guc: Don't ban LR VM exec queues on PM suspend

[Thomas Hellström]

When xe_guc_submit_stop() is called during an S3/S4 suspend or GT reset,
guc_exec_queue_stop() bans any user exec queue that has a job which has
started but not yet completed.  For normal (non-LR) exec queues this is
the correct behaviour: a started-but-incomplete job at reset time may
indicate a hung workload.

For exec queues attached to Long Running (LR) VMs the same condition is
always true during normal operation: LR jobs are designed to run
indefinitely and are never "completed" in the DRM scheduler sense —
they are preempted and resumed via the preempt-fence mechanism.
Banning such an exec queue on PM suspend permanently prevents the job
from restarting after resume, causing the userspace compute workload to
fail silently.

Fix this by skipping the ban for LR VM exec queues when a system
suspend or hibernation is in progress (pm_sleep_transition_in_progress()).
On GT reset the ban logic is preserved: a hung LR workload should still
be caught.

[PATCH 3/4] drm/xe: Restore userspace LRC BOs early on resume

[Thomas Hellström]

When GuC registers a context (REGISTER_CONTEXT G2H action), the LRC
buffer object must already be present in VRAM with valid content.
Userspace LRC BOs currently carry XE_BO_FLAG_PINNED_LATE_RESTORE, which
defers their restore to xe_bo_restore_late() — a blitter copy that runs
after xe_gt_resume().  However, xe_gt_resume() itself calls
xe_guc_submit_start(), which drives guc_exec_queue_start() ->
xe_sched_resubmit_jobs() -> guc_exec_queue_run_job() ->
register_exec_queue(), all before xe_bo_restore_late() has had a chance
to repopulate the BO.  The result is that GuC reads LRC state from
uninitialised VRAM and raises an exception.

Fix this by dropping XE_BO_FLAG_PINNED_LATE_RESTORE from the userspace
LRC BO flags.  Without that flag, the BO lands in the
pinned.early.kernel_bo_present list and is restored by
xe_bo_restore_early() via CPU/BAR copy before xe_gt_resume() is entered.
By the time any context registration fires the LRC VRAM is valid.

xe_bo_create_pin_map_novm() already adds XE_BO_FLAG_NEEDS_CPU_ACCESS and
XE_BO_FLAG_PINNED, satisfying the requirements of the CPU copy path.
Dropping XE_BO_FLAG_PINNED_LATE_RESTORE also makes force_contiguous()
return true for these BOs (PINNED without LATE_RESTORE), which is already
required for the GGTT mapping they carry.

[PATCH 4/4] drm/xe: Suspend fault-mode LR jobs before VRAM eviction on S3/S4

[Thomas Hellström]

Fault-mode (SVM) exec queues run persistent LR jobs that can re-fault
GPU page table entries at any time. During S3/S4 suspend, VRAM eviction
calls xe_vm_invalidate_vma() to unmap GPU VMAs, but a running fault-mode
job can immediately re-fault those pages back in, creating a race between
the GPU and the eviction.

Introduce xe_suspend_all_faulting_lr_jobs() which iterates all hw engine
groups across all GTs, suspends every fault-mode exec queue and waits for
the GuC to acknowledge the suspend before returning. This is called before
xe_bo_evict_all_user() in the PM notifier (user BO eviction) and before
xe_bo_evict_all() in xe_pm_suspend() (kernel/pinned BO eviction), ensuring
the GPU is idle before any mappings are torn down.

Unlike preempt-fence-mode VMs, fault-mode VMs don't use the rebind worker
on resume — rebinding happens lazily through GPU page fault handlers.
Therefore xe_resume_all_faulting_lr_jobs() is introduced to explicitly
re-register and resume all queues whose pm_suspended flag is set, mirroring
the same hw engine group iteration as the suspend path to ensure exact 1:1
pairing without relying on incidental GuC suspend state.

To prevent a new fault-mode exec queue from being added while PM suspend
is in progress, a pm_suspended flag is added to xe_hw_engine_group and
set under mode_sem before releasing the group lock in
xe_suspend_all_faulting_lr_jobs(). xe_hw_engine_group_add_exec_queue()
checks this flag under mode_sem: if set, the new queue is immediately
suspended (with lr.pm_suspended marked) so that the resume path picks it
up. If the group is additionally in EXEC_MODE_DMA_FENCE mode, a second
suspend is issued to match the mode-switch resumer, preserving the
one-suspend-per-resumer invariant from the suspend refcount. If the
queue is destroyed while PM-suspended, del_exec_queue() clears pm_suspended
under mode_sem so the resume path skips it cleanly.

The existing comment "FIXME: Super racey..." on xe_bo_evict_all() was
describing exactly this class of problem.

Hmm, thinking out aloud here, but what stops the hw executing the ring 
if we can get as far as run_job() this early? Thinking about non-LR, can 
we not have pending jobs that get re-submitted, before we have had a 
chance to restore the bb, page-tables, other user BOs etc, since that is 
maybe late restore also.

Good point. Need to look at that.

That's actually the case. I figure this might be hit if we use VRAM
page-tables for system BOs.

That case would potentially be fatal for preempt-fence mode as well,
I'll have to respin the fault mode patch to unconditionally suspend the
preempt-fence exec-queues, since with that case we might not see
eviction and hence no preempt-fences firing.

To me a decent fix would be to split up gt resume into two separate
steps. One registers migrate exec-queues and activates migrate
schedulers. Second does the same for user-space.

Yeah, fully agreed. I was also thinking the same here.
