Vendor Reset

The goal of this project is to provide a kernel module that is capable of resetting hardware devices into a state where they can be re-initialized or passed through into a virtual machine (VFIO). While it would be great to have these in the kernel as PCI quirks, some of the reset procedures are very complex and would never be accepted as a quirk (ie AMD Vega 10).

By providing this as an out of tree kernel module, vendors will be able to easily create pull requests to add functionallity to this module, and users will be able to easily update this module without requiring a complete kernel rebuild.

If you are a vendor intending to add support for your device to this project please first consider two things:

  1. Can you fix your hardware/firmware to reset correctly using FLR or a BUS reset?
  2. Is the reset simple enough that it should really be a kernel pci quirk (see: pci_quirk.c)?

If you answer yes to either of these questions this project is not for you.
