    PCI Peer-to-Peer DMA Support¶ The PCI bus has pretty decent support for performing DMA transfers between two devices on the bus. This type of transaction is henceforth called Peer-to-Peer (or P2P). However, there are a number of issues that make P2P transactions tricky to do in a perfectly safe way.

PCI Power Management — The Linux Kernel documentation

    https://www.kernel.org/doc/html/latest/power/pci.html
    PCI bus power management, however, is not supported by the Linux kernel at the time of this writing and therefore it is not covered by this document. Note that every PCI device can be in the full-power state (D0) or in D3cold, regardless of whether or not it implements the PCI PM Spec. ... To support the PCI runtime PM the driver first needs to ...
