Subject: [dpdk-dev] [PATCH v2 0/2] support IOMMU for DMA device
Date: Fri, 17 Sep 2021 05:25:44 +0000 [thread overview]
Message-ID: <20210917052546.23883-1-xuan.ding@intel.com> (raw)
In-Reply-To: <20210901053044.109901-1-xuan.ding@intel.com>
This series supports DMA device to use vfio in async vhost.
The first patch extends the capability of current vfio dma mapping
API to allow partial unmapping for adjacent memory if the platform
does not support partial unmapping. The second patch involves the
IOMMU programming for guest memory in async vhost.
v2:
* Added rte_errno filtering for some devices bound in the kernel driver.
* Added a flag to check the status of region mapping.
* Fixed one typo.
Xuan Ding (2):
vfio: allow partially unmapping adjacent memory
vhost: enable IOMMU for async vhost
