PATCH v3 1/1 mm: Fix a hmm_range_fault() livelock / starvation problem
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.
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)

hmm_range_fault()fails afolio_trylock()indo_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

migrate_device_unmap()->lru_add_drain_all()
Thelru_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 inmigrate_device_unmap(), so that there is a reason to calllru_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 totry_to_migrate(), which can happen after the call tolru_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 thedo_swap_page()function.Future code improvements might consider moving
thelru_add_drain_all()call inmigrate_device_unmap()to be called *after* all pages have migration entries inserted. That would eliminate also b) above.v2:

Code wise this looks fine to me, although it's confusing to see migration_entry_wait_on_locked() being called on a non-migration entry and ideally this would be renamed to something like softleaf_entry_wait_on_locked().
Regardless though the documentation for migration_entry_wait_on_locked() needs updating to justify why calling this on device-private entries is valid (because it's also just waiting for the page to be unlocked). Along with some equivalent justification for how we know there is a reference on the device-private page:
* If a migration entry exists for the page the migration path must hold
* a valid reference to the page, and it must take the ptl to remove the
* migration entry. So the page is valid until the ptl is dropped.
Which is basically just the page is mapped in the page table, therefore it must have a reference taken for the mapping and the mapping can't be removed while we hold the PTL.
Thanks.

If
hmm_range_fault()fails afolio_trylock()indo_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()
Thelru_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 inmigrate_device_unmap(), so that there is a reason to calllru_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 totry_to_migrate(), which can happen after the call tolru_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 thedo_swap_page()function.Future code improvements might consider moving
thelru_add_drain_all()call inmigrate_device_unmap()to be called *after* all pages have migration entries inserted. That would eliminate also b) above.v2:
- Instead of acond_resched()in thehmm_range_fault()function, eliminate the problem by waiting for the folio to be unlocked indo_swap_page()(Alistair Popple, Andrew Morton) v3:

migration_entry_wait_on_locked()being called on a non-migration entry and
ideally this would be renamed to something likesoftleaf_entry_wait_on_locked().Regardless though the documentation for
migration_entry_wait_on_locked()needs
updating to justify why calling this on device-private entries is valid (because
it's also just waiting for the page to be unlocked). Along with some equivalent
justification for how we know there is a reference on the device- private page:* If a migration entry exists for the page the migration
path must hold
* a valid reference to the page, and it must take the ptl
to remove the
* migration entry. So the page is valid until the ptl is
dropped.
Which is basically just the page is mapped in the page table, therefore it must
have a reference taken for the mapping and the mapping can't be removed while we
hold the PTL.

Thanks.

Thanks for reviewing. Let me respin this for a v4 addressing the above.
