Merge patch series "PCI: liveupdate: PCI core support for Live Update"
David Matlack <dmatlack@google.com> says:
This series introduces support in the PCI core for Live Update, enabling
drivers to preserve PCI devices across a kexec-based kernel update
without interrupting the device. This functionality is critical for
minimizing downtime in environments where PCI devices (e.g., those
assigned to VMs via VFIO) must continue operating or maintain state
across a host kernel upgrade.
Specifically, this series allows preserved PCI devices to perform
uninterrupted memory transactions (DMA) targeting system memory
(specifically, preserved memfds) across a Live Update. These devices can
be behind a bridge but must not be VFs. Support for P2P and VF
preservation will be addressed in future series.
