I've picked this up from David, keeping his patches but preventing to probe vfio-pci devices that can't be reset. Without this series starting qemu with a vfio-pci enabled device can lead to a kernel panic on Cavium systems, depending on the used hardware. Changes to v1 (https://lkml.org/lkml/2017/5/15/934): - Prevent probing by vfio-pci David Daney (2): PCI: Allow PCI_DEV_FLAGS_NO_BUS_RESET to be used on bus device PCI: Avoid bus reset for Cavium cn8xxx root ports Jan Glauber (1): vfio/pci: Don't probe devices that can't be reset drivers/pci/pci.c | 4 ++++ drivers/pci/quirks.c | 8 ++++++++ drivers/vfio/pci/vfio_pci.c | 6 ++++++ 3 files changed, 18 insertions(+) -- 2.9.0.rc0.21.g7777322
