The commit 523184972b28 doesn't apply because of another missing patch on 4.4.y kernel. commit ddf9dc0eb531 ("vfio-pci: Virtualize PCIe & AF FLR") Please apply commit ddf9dc0eb531 ("vfio-pci: Virtualize PCIe & AF FLR") before applying 523184972b28. commit ddf9dc0eb531 ("vfio-pci: Virtualize PCIe & AF FLR") also fixes a real issue as follows: "This seems to fix several instance of devices getting into bad states with userspace drivers, like dpdk, running inside a VM." It would be good to pull both to 4.y. I'll have to work on cf0d53ba4947 next. Sinan -- Sinan Kaya Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.
