[PATCH 3/3] drm/xe/ggtt: invalidate engine GGTT TLBs for multi-queue GTs

[tilak.tirumalesh.tangudu]

From: Tangudu Tilak Tirumalesh <tilak.tirumalesh.tangudu@intel.com>

Engines cache GGTT translations in their own TLBs, which the
xe_tlb_inval_ggtt() does not touch.
After a GGTT unmap the engines can still hit the stale translation and
read the old page.

Issue a FULL_INTRA_VF invalidation on GGTT unmap, gated on the GT
having any multi-queue engine class.

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [High] Engine TLB invalidation is incorrectly gated on a mutable software configuration flag, leading to stale TLBs and memory corruption when multi-queue scheduling is disabled.

drm/xe/ggtt: invalidate engine GGTT TLBs for multi-queue GTs

This commit introduces an engine TLB invalidation on GGTT unmap to ensure
that engines do not hit stale cached translations after the memory is freed.
The invalidation logic is gated on the GT having a multi-queue engine
class mask enabled.

[Severity: High]
Does this skip necessary hardware invalidation if the multi-queue scheduling
feature is disabled in software?

If a privileged user disables the multi-queue feature via configfs,
gt->info.multi_queue_engine_class_mask is cleared to 0. However, the hardware
physical capability of having independent engine TLBs does not disappear when
this software feature is disabled.

When the mask is cleared, xe_ggtt_invalidate_engine() will silently skip
the engine TLB invalidation on GGTT unmap, leaving the independent engine
TLBs unflushed and potentially causing data corruption or a use-after-free
when a recycled range is accessed. (Also note that in ggtt_node_remove(),
the unmap path falls back to writing a scratch PTE when this mask is 0,
which does not prevent engines from using their still-valid, stale TLB
entries.)

Should this check use an immutable hardware capability flag instead of the
active software configuration mask?

NIT...probably good to keep the name consistent.

As mentioned in other patch, probably good to abstract this into a
separate function with proper name and comment.

[PATCH 0/3] drm/xe/ggtt: fix stale GGTT mappings on unmap

[tilak.tirumalesh.tangudu]

From: Tangudu Tilak Tirumalesh <tilak.tirumalesh.tangudu@intel.com>

This series addresses two related GGTT teardown issues on multi-
queue platforms:

First issue: the unmap path mapped freed ranges to the scratch page.
Because scratch is a valid PTE, a re-walk of a freed range never
faults, so any stale TLB translation left behind is masked - the freed
range silently reads scratch instead of surfacing the problem. On
multi-queue platforms Patch 1 writes PTE=0 on unmap instead; other
platforms keep scratch, so free-hole and init-time handling are
unchanged.

Second issue: engines cache GGTT translations in their own TLBs. The
existing GGTT invalidation (xe_tlb_inval_ggtt()) does not reach those
engine-side TLBs, so after an unmap an engine can keep hitting the
stale translation and read the old page. Patches 2 and 3 add and use a
FULL_INTRA_VF invalidation to drain the engine TLBs on unmap.

Patch 1: drm/xe/ggtt: stop mapping unmapped GGTT pages to scratch
    On multi-queue platforms write PTE=0 on unmap so a stale-TLB
    access to a freed range faults instead of silently landing on
    scratch.

Patch 2: drm/xe/tlb_inval: add FULL_INTRA_VF GGTT invalidation helper
    xe_tlb_inval_ggtt_full() + GuC backend flush engine TLBs across
    all engines in the requesting VF partition.

Patch 3: drm/xe/ggtt: invalidate engine GGTT TLBs for multi-queue GTs
    Issue the FULL_INTRA_VF invalidation on the unmap path, gated on
    the GT having any multi-queue engine class. Draining the engine
    TLB on teardown guarantees a recycled range's next occupant cannot
    hit the predecessor's cached translation.

v2: Add xe_gt_has_multi_queue() helper and refactor.
    Add xe_tlb_inval_issue_op_wait and refactor.
    Other knits.

[PATCH 1/3] drm/xe/ggtt: stop mapping unmapped GGTT pages to scratch

[tilak.tirumalesh.tangudu]

From: Tangudu Tilak Tirumalesh <tilak.tirumalesh.tangudu@intel.com>

xe_ggtt_clear() wrote a scratch PTE across the range for both
initial_clear() and the node_remove() unmap path.

On unmap the scratch PTE hides stale-TLB gaps: after the range is
invalidated a re-walk lands on the still-valid scratch PTE, so a stale
engine TLB translation for the freed range never faults and the
invalidation gap stays invisible.

Add an explicit use_scratch bool. initial_clear() keeps writing scratch.
On multi-queue platforms, where engines cache GGTT independently,
node_remove() writes PTE=0 so a stale translation to a freed range
faults and the gap becomes observable; other platforms keep scratch.

v2: Add xe_gt_has_multi_queue() helper and other knits-Niranjana

[PATCH 3/3] drm/xe/ggtt: invalidate engine GGTT TLBs for multi-queue GTs

[tilak.tirumalesh.tangudu]

From: Tangudu Tilak Tirumalesh <tilak.tirumalesh.tangudu@intel.com>

Engines cache GGTT translations in their own TLBs, which the
xe_tlb_inval_ggtt() does not touch.
After a GGTT unmap the engines can still hit the stale translation and
read the old page.

Issue an INVAL_FULL (intra vf) invalidation on GGTT unmap, gated on the
GT having any multi-queue engine class.

v2: Use xe_gt_has_multi_queue() helper and other knits. - Niranjana

drm/xe/ggtt: stop mapping unmapped GGTT pages to scratch

This commit updates xe_ggtt_clear() to take a use_scratch parameter, leaving
the init-time clear to use scratch PTEs while forcing PTE=0 during node 
removal on multi-queue platforms. This aims to expose stale hardware TLB 
entries as observable faults.

[Severity: High]
Does this explanation imply that hardware prefetchers speculatively walk
into unmapped ranges?

If engines legitimately walk free holes (as stated here for the init-time
clear), the hardware prefetcher cannot distinguish between virgin holes and
recycled holes.

[Severity: High]
Can writing PTE=0 here cause spurious GPU or IOMMU page faults on
multi-queue platforms?

Since a prefetching engine might speculatively read past its buffer boundary
into an adjacent recycled hole, stripping the scratch PTE protection for
recycled memory while keeping it for virgin memory creates a situation
where faults depend entirely on memory allocation history.

Could this lead to engine hangs or system instability when a prefetching
engine hits the PTE=0 in a recently freed node?

drm/xe/ggtt: invalidate engine GGTT TLBs for multi-queue GTs

This commit adds engine-side GGTT TLB invalidation during GGTT unmap
operations to ensure engines don't hit stale translations. The invalidation
is only issued if the GT has multi-queue engine classes.

[Severity: Medium]
Will this miss invalidating the engine TLBs on the media GT? 

If the media GT has multi-queue engine classes, hardcoding primary_gt here
seems like it would skip the media engines entirely, even though the GGTT
is shared across the entire tile. For comparison, xe_ggtt_invalidate() just
above invalidates both the primary and media GTs.

NIT...Kernel-doc not really needed for static functions. General comment section
should be good. I prefer keeping it simple with general comment, but leaving it
as is is fine too.

Kernel-doc not really required for static functions, general comment (or no comment)
would do.

Anycase, LGTM.

NIT...may be here or in xe_ggtt_invalidate_engine(), it is good to add a note
that for simplicity, flush the full TLB instead of context based invalidation?

NIT...Given we have a has_multi_queue check in this function, perhaps add
"It is needed in multi-queue case because, ..."?

Anyway, LGTM

I'm a little confused about the rationale here. Can you elaborate on why
this is being done?

I also don't really like that we boot with the entire GGTT pointing to
scratch pages and then, over time, as we map and unmap entries in the
GGTT, it gradually becomes populated with unmapped entries that no
longer point to scratch.

This means the behavior can change over time. For example, immediately
after boot, prefetches into unmapped GGTT regions do not fault because
they hit scratch pages. Later on, the same prefetch may fault because
the corresponding GGTT entry no longer points to scratch.

The answer for scratch needs to be either "on" or "off", not something
that changes dynamically at unmap time. I'm fine with deciding to turn
this off, but the behavior needs to remain consistent for a given boot
and platform.

This is a TOCTOU issue. For example, the CT state can change immediately
after the check,

send_tlb_inval_ggtt() has the same problem and likely isn't 100% correct
either.

I'd prefer that we don't make this situation any worse.

Would something like this work?

ret = send_tlb_inval(guc, action, ARRAY_SIZE(action));
if (ret)
	return -ECANCELED;

This would allow the CT layer, under the appropriate lock, to determine
whether it is still alive. If the GuC CT is no longer live, we know that
nothing can be running on the engines, so returning -ECANCELED would
signal the fence appropriately.

Everything else LGTM.

For future-proofing, look similar too xe_ggtt_invalidate():

It should attempt to invalidate both the primary and media GTs. The
media GT will either be NULL or have xe_gt_has_multi_queue() == false,
in which case xe_tlb_inval_ggtt_full() will be skipped for that GT.

Sashiko also flagged this as a potential issue, not functional thing but
good feedback.
