X-Received-From: 192.55.52.115 Subject: [Qemu-devel] [RFC v1 07/18] hw/pci: add pci_device_bind/unbind_gpasid X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: tianyu.lan@intel.com, kevin.tian@intel.com, yi.l.liu@intel.com, Yi Sun , kvm@vger.kernel.org, jun.j.tian@intel.com, eric.auger@redhat.com, yi.y.sun@intel.com, Jacob Pan , david@gibson.dropbear.id.au Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP This patch adds two callbacks pci_device_bind/unbind_gpasid() to PCIPASIDOps. These two callbacks are used to propagate guest pasid bind/unbind to host. The implementations of the callbacks would be device passthru modules like vfio.
