Normally scratch page is not allowed when a vm is operate under page
fault mode, i.e., in the existing codes, DRM_XE_VM_CREATE_FLAG_SCRATCH_PAGE
and DRM_XE_VM_CREATE_FLAG_FAULT_MODE are mutual exclusive. The reason
is fault mode relies on recoverable page to work, while scratch page
can mute recoverable page fault.
On xe2 and xe3, HW prefetching can cause page fault interrupt. Due to
page fault interrupt overhead (i.e., need Guc and KMD involved to fix
the page fault), HW prefetching can be slowed by many orders of magnitude.
Fix this problem by allowing scratch page under fault mode for xe2 and xe3.
With scratch page in place, HW prefetching could always hit scratch page
instead of causing interrupt.

LGTM, though see my comment for patch 2 regarding the added platform checks.

The problem on xe2 and xe3 as I understand it is not the overhead but
the fact that OOB prefetching causes pagefaults and we can't resolve
those.

Could we perhaps add a bit in the xe->info structure?

On some platform, scratch page is needed for out of bound prefetch
to work. Introduce a bit in device descriptor to specify whether
this device needs scratch page to work.
v2: introduce a needs_scratch bit in device info (Thomas, Jonathan)

When a vm runs under fault mode, if scratch page is enabled, we need
to clear the scratch page mapping before vm_bind for the vm_bind
address range. Under fault mode, we depend on recoverable page fault
to establish mapping in page table. If scratch page is not cleared,
GPU access of address won't cause page fault because it always hits
the existing scratch page mapping.
When vm_bind with IMMEDIATE flag, there is no need of clearing as
immediate bind can overwrite the scratch page mapping.
So far only is xe2 and xe3 products are allowed to enable scratch page
under fault mode. On other platform we don't allow scratch page under
fault mode, so no need of such clearing.
v2: Rework vm_bind pipeline to clear scratch page mapping. This is similar
to a map operation, with the exception that PTEs are cleared instead of
pointing to valid physical pages. (Matt, Thomas)
TLB invalidation is needed after clear scratch page mapping as larger
scratch page mapping could be backed by physical page and cached in
TLB. (Matt, Thomas)

Normally scratch page is not allowed when a vm is operate under page
fault mode, i.e., in the existing codes, DRM_XE_VM_CREATE_FLAG_SCRATCH_PAGE
and DRM_XE_VM_CREATE_FLAG_FAULT_MODE are mutual exclusive. The reason
is fault mode relies on recoverable page to work, while scratch page
can mute recoverable page fault.
On xe2 and xe3, out of bound prefetch can cause page fault and further
system hang because xekmd can't resolve such page fault. SYCL and OCL
language runtime requires out of bound prefetch to be silently dropped
without causing any functional problem, thus the existing behavior
doesn't meet language runtime requirement.
At the same time, HW prefetching can cause page fault interrupt. Due to
page fault interrupt overhead (i.e., need Guc and KMD involved to fix
the page fault), HW prefetching can be slowed by many orders of magnitude.
Fix those problems by allowing scratch page under fault mode for xe2 and
xe3. With scratch page in place, HW prefetching could always hit scratch
page instead of causing interrupt.
A side effect is, scratch page could hide application program error.
Application out of bound accesses are hided by scratch page mapping,
instead of get reported to user.

I think we need to ephasize that we clear AT vm_bind time, not before,
both in the commit description and the patch title.

I think there might be some things missing here.
The bind should look exactly as a is_null bind, with the exception that
the pte should be 0, so might be able to benefit from is_null, for
example xe_pg_hugepte_possible() short-circuit the dma-address check.
With clear_pt we don't want to use the XE_PTE_PS64K, though, like you
identified above.
Will get back with a look at the invalidation.

You are right. Above code has a problem for huge pte cases: it wouldn't detect
A huge pte for clear_pt case. I will fix it.
I will not make is_null be true for clear_pt case, but will make similar logic to
Let clear_pt benefit from is_null logic.

I don't quite get here. Please do let me know if you find anything.

Below wa code is for dg2.
If we move this test below the wa code, then on dg2, if people create vm
With FAULT_MODE | LR_MODE, above check would fail user.
So I do think we should keep this check above wa codes.

* [PATCH 3/3] drm/xe: Allow scratch page under fault mode for certain platform
2025-02-06 2:11 [PATCH 1/3] drm/xe: Introduced needs_scratch bit in device descriptor Oak Zeng
@ 2025-02-06 2:11 ` Oak Zeng
0 siblings, 0 replies; 38+ messages in thread

Normally scratch page is not allowed when a vm is operate under page
fault mode, i.e., in the existing codes, DRM_XE_VM_CREATE_FLAG_SCRATCH_PAGE
and DRM_XE_VM_CREATE_FLAG_FAULT_MODE are mutual exclusive. The reason
is fault mode relies on recoverable page to work, while scratch page
can mute recoverable page fault.
On xe2 and xe3, out of bound prefetch can cause page fault and further
system hang because xekmd can't resolve such page fault. SYCL and OCL
language runtime requires out of bound prefetch to be silently dropped
without causing any functional problem, thus the existing behavior
doesn't meet language runtime requirement.
At the same time, HW prefetching can cause page fault interrupt. Due to
page fault interrupt overhead (i.e., need Guc and KMD involved to fix
the page fault), HW prefetching can be slowed by many orders of magnitude.
Fix those problems by allowing scratch page under fault mode for xe2 and
xe3. With scratch page in place, HW prefetching could always hit scratch
page instead of causing interrupt.
A side effect is, scratch page could hide application program error.
Application out of bound accesses are hided by scratch page mapping,
instead of get reported to user.

I think what matters here is readability of the code. A naive reader
(like me in this case) would start to wonder why enabling scratch pages
*after* the sanity check for them is done, and whether that is a bug or
an oversight, and that would require looking up what the WA actually
means.
So IMO in general sanity checks should be done after all implicit
enabling of flags if at all possible. And if not, they should be
accompanied by a comment that explains why the enabling of the flag is
not included in the sanity check.

Given the complexity of the VM bind path, I think we need an IGT posted
with this series before merging as I suggested in v1. Without it, it
will be fairly difficult to ensure correctness by reviews only.

There is an igt posted that exercises xe_exec_fault_mode + scratch
pages. Although you might have had something more elaborate in mind?

Yes, I meant I hadn't had time to look at this part yet.
For binding with scratch, it looks like *all* binds need TLB
invalidation, not just clearing binds, So in the below code-path, can't
we just replace the xe_vm_in_preempt_fence_mode() with
xe_vm_in_lr_mode()?
/*
* If rebind, we have to invalidate TLB on !LR vms to
invalidate
* cached PTEs point to freed memory. On LR vms this
is done
* automatically when the context is re-enabled by the
rebind worker,
* or in fault mode it was invalidated on PTE zapping.
*
* If !rebind, and scratch enabled VMs, there is a
chance the scratch
* PTE is already cached in the TLB so it needs to be
invalidated.
* On !LR VMs this is done in the ring ops preceding a
batch, but on
* non-faulting LR, in particular on user-space batch
buffer chaining,
* it needs to be done here.
*/
if ((!pt_op->rebind && xe_vm_has_scratch(vm) &&
xe_vm_in_preempt_fence_mode(vm)))

I think you are correct.
For long run vm, regardless it is in fault mode or not, we need to invalidate
TLB scratch page caching during bind. Original codes only did TLB inv on non-
Fault mode. On fault mode + LR, this runs into two sub-cases:
1. immediate bind
2. bind triggered by page fault: note this can actually runs into the !rebind case
When the fault address is first time accessed by gpu. But the TLB cache for
Scratch page mapping should have been invalidated by the "invalidate_on_bind"
Condition.
So this leaves case #1 problematic.
It would be better for others to comment also, as in the comment below, it explicitly
Called out "non-faulting LR". My understanding is, people didn't think of case #1 above.
Since it is an existing issue, I will make it a separate patch for better tracking purpose.

* [PATCH 3/3] drm/xe: Allow scratch page under fault mode for certain platform
2025-02-06 21:38 [PATCH 1/3] drm/xe: Introduced needs_scratch bit in device descriptor Oak Zeng

Normally scratch page is not allowed when a vm is operate under page
fault mode, i.e., in the existing codes, DRM_XE_VM_CREATE_FLAG_SCRATCH_PAGE
and DRM_XE_VM_CREATE_FLAG_FAULT_MODE are mutual exclusive. The reason
is fault mode relies on recoverable page to work, while scratch page
can mute recoverable page fault.
On xe2 and xe3, out of bound prefetch can cause page fault and further
system hang because xekmd can't resolve such page fault. SYCL and OCL
language runtime requires out of bound prefetch to be silently dropped
without causing any functional problem, thus the existing behavior
doesn't meet language runtime requirement.
At the same time, HW prefetching can cause page fault interrupt. Due to
page fault interrupt overhead (i.e., need Guc and KMD involved to fix
the page fault), HW prefetching can be slowed by many orders of magnitude.
Fix those problems by allowing scratch page under fault mode for xe2 and
xe3. With scratch page in place, HW prefetching could always hit scratch
page instead of causing interrupt.
A side effect is, scratch page could hide application program error.
Application out of bound accesses are hided by scratch page mapping,
instead of get reported to user.

Ah, missed this as generally look at cover letter to find associated
IGTs.
A quick look at IGT and thinking we need to do slightly better. Off the
top of my head something like:
- Run a batch which does a DW write to scratch address
- Bind scratch address /w IMMEDIATE cleared
- Run a batch which does a DW write to newly bound address, verfiy
result

* [PATCH 3/3] drm/xe: Allow scratch page under fault mode for certain platform

Normally scratch page is not allowed when a vm is operate under page
fault mode, i.e., in the existing codes, DRM_XE_VM_CREATE_FLAG_SCRATCH_PAGE
and DRM_XE_VM_CREATE_FLAG_FAULT_MODE are mutual exclusive. The reason
is fault mode relies on recoverable page to work, while scratch page
can mute recoverable page fault.
On xe2 and xe3, out of bound prefetch can cause page fault and further
system hang because xekmd can't resolve such page fault. SYCL and OCL
language runtime requires out of bound prefetch to be silently dropped
without causing any functional problem, thus the existing behavior
doesn't meet language runtime requirement.
At the same time, HW prefetching can cause page fault interrupt. Due to
page fault interrupt overhead (i.e., need Guc and KMD involved to fix
the page fault), HW prefetching can be slowed by many orders of magnitude.
Fix those problems by allowing scratch page under fault mode for xe2 and
xe3. With scratch page in place, HW prefetching could always hit scratch
page instead of causing interrupt.
A side effect is, scratch page could hide application program error.
Application out of bound accesses are hided by scratch page mapping,
instead of get reported to user.

I'd drop this macro. These are leftovers from the i915 code and I see
like value in a macro looking directly at a field. In the existing cases
these macros are used all over the code so they make a little more sense
so if change the variable we only have change this macro, but in this
new case the macro is used 2 places in the code so I'd say just look at
the variable.

Same comment as patch #1, I'd drop this macro.
Do we need a query uAPI so the UMD can test upon process open if the VM
supports scratch page + faults? Or should we just not restrict VM
scratch page + faults ever and have it choose based on platform
recommnedation?

Do we need a query uAPI so the UMD can test upon process open if the VM
supports scratch page + faults? Or should we just not restrict VM
scratch page + faults ever and have it choose based on platform
recommnedation?

Introducing a query API seems a little overkill to me.
Maybe I can add a little comment in the xe_drm.h, saying scratch and fault
Flags are normally mutual exclusive except on xe2/3?

I think having above checking/restriction is still helpful.

This is really a question for the level0 UMD I suppose, I'd follow up
there. They have asked for a query uAPI for other seemly simple things
before.
