One is adding iommu_dev_enable/disable_feature IOMMU_DEV_FEAT_SVA,
which you have patchset before.
Yes, I have a more complete version of that here someplace. Need some
help on vt-d but hope to get that done next cycle.
Can you please elaborate this a bit more? Are you talking about below
change
+ ret = iommu_dev_enable_feature(idev->dev, IOMMU_DEV_FEAT_SVA);
+ if (ret)
+ return ret;
in iommufd_fault_iopf_enable()?
I have no idea about why SVA is affected when enabling iopf.
