On multi-queue platforms an engine can retain a stale GGTT TLB entry
for a range that has since been unmapped and recycled. When unmapped
GGTT entries resolve to the scratch page, such a stale access lands on
scratch silently instead of faulting, masking the error.
On multi-queue platforms, skip allocating the GGTT scratch page so
cleared and unmapped ranges hold PTE=0. The whole GGTT then
consistently faults on unmapped access for the entire boot; other
platforms keep the scratch page and are unaffected.
v2:
- Add xe_gt_has_multi_queue() helper and address nits (Niranjana)
v3:
- Drop scratch entirely instead of toggling per-unmap (Matt Brost)

This series addresses two related GGTT teardown issues on multi-queue
platforms:
First issue: unmapped GGTT ranges resolve 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 does not allocate the scratch page at all, so the whole GGTT -
initial clear and unmap alike - holds PTE=0 and faults consistently for
the entire boot. Other platforms keep scratch and 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
(INVAL_FULL, intra-VF) invalidation to drain the engine TLBs on unmap.
Patch 1: drm/xe/ggtt: fault on unmapped GGTT for multi-queue platforms
Skip allocating the GGTT scratch page on multi-queue platforms so
cleared and unmapped ranges hold PTE=0 and a stale-TLB access to a
freed range faults instead of silently landing on scratch.
Patch 2: drm/xe/tlb_inval: add xe_tlb_inval_ggtt_full() GGTT
invalidation helper
xe_tlb_inval_ggtt_full() + GuC backend flush engine TLBs across all
engines within the requesting VF.
Patch 3: drm/xe/ggtt: invalidate engine GGTT TLBs for multi-queue GTs
Issue the invalidation on the unmap path, gated on the GT having any
multi-queue engine class, for both the primary and media GTs.
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 gate on it (Niranjana).
- Add xe_tlb_inval_issue_op_wait() and refactor the GGTT
invalidation entry points onto it (Niranjana).
- Other nits.
v3:
- Patch 1: drop the scratch page entirely on multi-queue platforms
instead of toggling scratch vs faulting at unmap, so the behaviour
is consistent for the whole boot (Matt Brost).
- Patch 2: avoid the CT-state TOCTOU; (Matt Brost).
- Patch 3: invalidate both the primary and media GTs, similar to
xe_ggtt_invalidate() (Matt Brost)
v4:
- Patch 2: propagate real send errors instead of masking them as
-ECANCELED (Sashiko).

Add xe_tlb_inval_ggtt_full() and its GuC backend
send_tlb_inval_ggtt_full() for full engine TLB invalidation
within the requesting VF across all engines.

nits (Niranjana)
v3:
- Avoid TOCTOU issue around CT state (Matt Brost)
v4:
- Propagate real send errors instead of masking as -ECANCELED (Sashiko)

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 address nits (Niranjana)
v3:
- Invalidate both the primary and media GTs, similar to
xe_ggtt_invalidate() (Matt Brost)

NIT...Comment sounds bit misleading, propbably good to reword.
May be, "For multi-queue platforms..."

Looks like we don't need the check 'ret == -ECANCELED' here (redundent).
Basically, we only need,
if (ret == -ENODEV)
ret = -ECANCELED;
Also, It seems bit odd that other functions like send_tlb_inval_all(),
send_tlb_inval_lmmtt() etc, has similar structure and similar documentation in
xe_tlb_inval_types.h (regarding -ECANCELED), but doesn't do this conversion.
So, they are not treating XE_GUC_CT_STATE_DISABLED (where guc_ct_send returns
ENODEV) as a 'cancelled' state. May be here also we should do that for now,
if we need fix, then it will be a fix for all of these callback functions later.

Acutally, this would require an explanation here as to why we are
doing it only for multi queue here. Or, we should pass a bitmask of GT types
that require an invalidation while invoking xe_ggtt_invalidate_engine().
As these are all static functions here, I think a comment here that should
be good enough.
Also, may be check for '!gt' also to keep is similar to ggtt_invalidate_gt_tlb.
Otherwise, LGTM

I think actually -ENODEV is needed because it is odd corner that only
GGTT invalidations can legitimently hit with a blind CT send which was
my suggestion.
-ENODEV is the return if the CT is disabled (cold boot start)
-ECANCELED is return if the CT is stopped (runtime toggle)
GGTT invalidations can be issued during cold boots as these are kernel
objects, PPGTT cannot because these are user objects.
Thus, I think this actually correct in the current code.

Opps one more thing - iirc wedge devices return a different error code,
but that might be getting revert. We should check on that as I think
wedged needs to be handle here.

Drive-by question; I haven't reviewed the changes in depth. How does
multi-queue relate to GGTT here? Multi-queue submission is something
userspace can do, but those userspace submissions can't access the GGTT,
only the PPGTT. GGTT accesses would only come from privileged
instructions that the KMD inserts into the ring and I don't think those
are ever multi-queue. Am I overlooking something? It seems like GGTT
and multi-queue should be orthogonal.

The ring buffer is GGTT mapped (?), multi-q doesn't context switch like
normal q, if we missed TLB invalidations we get slient errors as scratch
could be prefetched into the TLBs - this is my *guess*. More below.

Also my question from the last rev has yet to be answered:
I'm a little confused about the rationale here. Can you elaborate on why
this is being done?
I'm inferring this is done to detect missing TLB invalidations but this
is not stated anywhere - i.e., a reader of the code can't lookat the at
the git log or comments in the code to figure why multi-q doesn't use
scratch and everyone else does. Likewise the commit message should or
code comment should answer Matt's R question as well.

During secondary queue append, Guc does lite restore and skips full context restore, so
TLB invalidations are missed. This was observed while running multi queue tests
on another OS. We now detect the miss and do explicit flush on unmap.
I will add this in commit message and will add one liner comment in the code

* [PATCH 1/3] drm/xe/ggtt: fault on unmapped GGTT for multi-queue platforms

From: Tangudu Tilak Tirumalesh <tilak.tirumalesh.tangudu@intel.com>
Engines cache GGTT translations in their TLBs.
A full context restore on engine switch flushes these, so a stale
translation for an unmapped and recycled range does not survive.
During a secondary queue append, GuC does a lite-restore and skips the
full context restore, so engine TLB invalidations are missed. This was
observed while running multi-queue tests on another OS.
If unmapped GGTT points to scratch, such a stale access silently reads
scratch instead of faulting, masking the error. On multi-queue
platforms skip allocating the scratch page so unmapped GGTT holds
PTE=0 and faults consistently for the whole boot; other platforms keep
scratch and are unaffected.
v2:
- Add xe_gt_has_multi_queue() helper and address nits (Niranjana)
v3:
- Drop scratch entirely instead of toggling per-unmap (Matt Brost)
v5:
- Document the rationale (Matt Roper / Matt Brost)
