Subject: [PATCH 00/11] Convert Intel IOMMU to use sva-lib helpers
Date: Thu, 20 May 2021 11:15:20 +0800 [thread overview]
Message-ID: <20210520031531.712333-1-baolu.lu@linux.intel.com> (raw)
This patch series converts the Intel IOMMU to use the generic sva
helpers defined in iommu-sva-lib.c and io-pgfault.c. It includes the
SVA pasid management and IO page fault handling.
This series could be divided into below parts:
PATCH[1~3]: Use iommu_sva_alloc/free_pasid() to manage the SVA pasid.
PATCH[4-6]: Use the generic sva io page fault handler iommu_queue_iopf.
PATCH[7-11]: Add ftrace and debugfs support for io page fault handling.
Please help to review.
Best regards,
baolu
