This patch is the last one of set "crypto: qat - enable QAT GEN4 SR-IOV VF live migration" [1]. The first 1~9 patches of this set introduce the helpers in QAT PF driver to support the live migration of Intel QAT SR-IOV VF device and have been merged into Herbert's tree [2]. This one adds a vfio pci extension specific for QAT which intercepts the vfio device operations for a QAT VF to allow live migration. Changes in v6 since v5 [1]: - Introduce more QAT device specific information around migration in the commit message and comments in driver (Alex) [1]: https://lore.kernel.org/kvm/20240306135855.4123535-1-xin.zeng@xxxxxxxxx/ [2]: https://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git/commit/?id=f0bbfc391aa7eaa796f09ee40dd1cd78c6c81960 Xin Zeng (1): vfio/qat: Add vfio_pci driver for Intel QAT SR-IOV VF devices MAINTAINERS | 8 + drivers/vfio/pci/Kconfig | 2 + drivers/vfio/pci/Makefile | 2 + drivers/vfio/pci/qat/Kconfig | 12 + drivers/vfio/pci/qat/Makefile | 3 + drivers/vfio/pci/qat/main.c | 679 ++++++++++++++++++++++++++++++++++ 6 files changed, 706 insertions(+) create mode 100644 drivers/vfio/pci/qat/Kconfig create mode 100644 drivers/vfio/pci/qat/Makefile create mode 100644 drivers/vfio/pci/qat/main.c base-commit: f0bbfc391aa7eaa796f09ee40dd1cd78c6c81960 -- 2.18.2
