** Description changed:
- In Ubuntu kernel version 4.15, Downstream Port Containment (DPC) is set too
aggressively and will trigger DPC on NON-FATALs. In newer kernels it is set to
trigger on FATALs.
- Additionally, the DPC will consume the interrupt before passing it on to AER
for analysis.
- Finally, udev is not notified of device offline events by AER.
+ DPC trigger changed to FATAL with commit:
- In order to support PCI DPC and AER more effectively in 4.15, please
- backport the following commits from upstream. Most of these are either
- refactors or cleanups:
