Thanks for the data. I am puzzled about how could IR fault be related
to the strict mode. We don't defer flushing for IR. The only thing is
that queued invalidation interface is shared, where the non-strict mode
may hold up the QI longer from time to time.
perhaps add a printk in modify_irte() and see if that fault happens
around IRTE updates.
e.g.
@@ -170,10 +171,15 @@ static int modify_irte(struct irq_2_iommu
*irq_iommu, index = irq_iommu->irte_index + irq_iommu->sub_handle;
irte = &iommu->ir_table->base[index];
+ pr_debug("irte h:%llx l:%llx, sid:%x\n",
+ irte_modified->high, irte_modified->low,
irte_modified->sid); +

All I can say is that the following IRTE dump looks sane. You might be
able to relax the SID check from full 16bit to 13bit which excludes
the three function bits. (bit 80-81 SQ=0b11). But i doubt it is the
issue.
