[Impact]
Using vfio-pci on a combination of cn8xxx and some PCI devices results in a kernel panic. This is triggered by issuing a bus or a slot reset on the PCI device.
[Fix]
The following patches checks indicate that the reset is not possible
preventing the kernel panic.
357027786f35 PCI: Avoid bus reset if bridge itself is broken
822155100e58 PCI: Mark Cavium CN8xxx to avoid bus reset
33ba90aa4d44 PCI: Avoid slot reset if bridge itself is broken
These patches are already in Bionic, we need these patches in Artful so that xenial linux-hwe also has the fix.
[Test]
- Artful Host with Artful/bionic guests
- Pass though PCI device (vfio-pci) from Artful to bionic and make sure its usable.
- The device should pass through and not cause a kernel panic.
[Regression Potential]
None. |
