If hmm_range_fault() fails a folio_trylock() in do_swap_page,
trying to acquire the lock of a device-private folio for migration,
to ram, the function will spin until it succeeds grabbing the lock.
However, if the process holding the lock is depending on a work
item to be completed, which is scheduled on the same CPU as the
spinning hmm_range_fault(), that work item might be starved and
we end up in a livelock / starvation situation which is never
resolved.
This can happen, for example if the process holding the
device-private folio lock is stuck in
migrate_device_unmap()->lru_add_drain_all()
The lru_add_drain_all() function requires a short work-item
to be run on all online cpus to complete.
A prerequisite for this to happen is:
a) Both zone device and system memory folios are considered in
migrate_device_unmap(), so that there is a reason to call
lru_add_drain_all() for a system memory folio while a
folio lock is held on a zone device folio.
b) The zone device folio has an initial mapcount > 1 which causes
at least one migration PTE entry insertion to be deferred to
try_to_migrate(), which can happen after the call to
lru_add_drain_all().
c) No or voluntary only preemption.
This all seems pretty unlikely to happen, but indeed is hit by
the "xe_exec_system_allocator" igt test.
Resolve this by waiting for the folio to be unlocked if the
folio_trylock() fails in the do_swap_page() function.
Rename the migration_entry_wait_on_locked() function to
softleaf_entry_wait_unlock() and update its documentation to
indicate the new use-case.
Future code improvements might consider moving
the lru_add_drain_all() call in migrate_device_unmap() to be
called *after* all pages have migration entries inserted.
That would eliminate also b) above.
v2:
- Instead of a cond_resched() in the hmm_range_fault() function,
eliminate the problem by waiting for the folio to be unlocked
in do_swap_page() (Alistair Popple, Andrew Morton)
v3:
- Add a stub migration_entry_wait_on_locked() for the
!CONFIG_MIGRATION case. (Kernel Test Robot)
v4:
- Rename migrate_entry_wait_on_locked() to
softleaf_entry_wait_on_locked() and update docs (Alistair Popple)

Do you have a stack trace from the test? I am trying to visualize the
livelock/starvation, but I can't from the description.

@Alistair, any chance of an R-B for the below version?
@Andrew, will this go through the -mm tree or alternaltively an ack for
merging through drm-xe-fixes?

Either works. I'll grab a copy. It you want to take this via drm then
I'll drop the mm.git copy once the drm tree's version appears in linux-next.

So apart from the rename, this is the whole patch. This got nicer!

For sure. Sorry I've been getting back to this but caught up with internal
stuff.

I noticed this just because we didn't have it previously, but I assume it's to
avoid compilation failures in do_swap_page(). This is definitely the better way
of dealing with the conditional compilation, though if I were to add a nit it
would be that a WARN_ON_ONCE() would be nice here.
But this is fine, and thanks for doing the rename. Feel free to add:
