RE: [PATCH v1 0/8] Add IO page table replacement support

From: Nicolin Chen nicolinc@nvidia.com Sent: Thursday, February 2, 2023 3:05 PM

QEMU with this feature should have the vIOMMU maintain a cache of the guest io page table addresses and assign a unique IOAS to each unique guest page table.

I didn't get why we impose such requirement to userspace.

To apply this series, please rebase on top of the following patches:

1. [PATCH 00/13] Add vfio_device cdev for iommufd support https://lore.kernel.org/kvm/20230117134942.101112-1-yi.l.liu@intel.com/
2. (Merged) [PATCH v5 0/5] iommu: Retire detach_dev callback https://lore.kernel.org/linux-iommu/20230110025408.667767-1-

baolu.lu@linux.intel.com/ 3) (Merged) [PATCH] selftests: iommu: Fix test_cmd_destroy_access() call in user_copy https://lore.kernel.org/lkml/20230120074204.1368-1-nicolinc@nvidia.com/

No need to list merged work as dependency. In concept every commit merged in the version which this series is rebased to is required. 😊
