linux-toradex.git/drivers/vfio/pci/qat/Makefile, branch master Linux kernel for Apalis and Colibri modules vfio/qat: Add vfio_pci driver for Intel QAT SR-IOV VF devices 2024-04-29T19:25:41+00:00 Xin Zeng xin.zeng@intel.com 2024-04-26T06:40:51+00:00 bb208810b1abf1c84870cfbe1cc9cf1a1d35c607 Add vfio pci variant driver for Intel QAT SR-IOV VF devices. This driver registers to the vfio subsystem through the interfaces exposed by the subsystem. It follows the live migration protocol v2 defined in uapi/linux/vfio.h and interacts with Intel QAT PF driver through a set of interfaces defined in qat/qat_mig_dev.h to support live migration of Intel QAT VF devices. This version only covers migration for Intel QAT GEN4 VF devices.
