Hi Yi, Vivek,
[...]
I see. I think there needs a change in the code there. Should also expect
a nesting_info returned instead of an int anymore. @Eric, how about your
opinion?
domain = iommu_get_domain_for_dev(&vdev->pdev->dev);
ret = iommu_domain_get_attr(domain, DOMAIN_ATTR_NESTING,
&info);
if (ret || !(info.features & IOMMU_NESTING_FEAT_PAGE_RESP)) {
/*
* No need go futher as no page request service support.
*/
return 0;
}
Sure I think it is "just" a matter of synchro between the 2 series. Yi,
exactly.
do you have plans to respin part of
[PATCH v7 00/16] vfio: expose virtual Shared Virtual Addressing to VMs
or would you allow me to embed this patch in my series.
My v7 hasn’t touch the prq change yet. So I think it's better for you to
embed it to your series. ^_^>>
Can you please let me know if you have an updated series of these
patches? It will help me to work with virtio-iommu/arm side changes.
As per the previous discussion, I plan to take those 2 patches in my
SMMUv3 nested stage series:
[PATCH v7 01/16] iommu: Report domain nesting info
[PATCH v7 02/16] iommu/smmu: Report empty domain nesting info
we need to upgrade both since we do not want to report an empty nesting
info anymore, for arm.
Absolutely. Let me send the couple of patches that I have been using,
that add arm configuration.
Best regards
Vivek
Thanks
Eric
