If needed, PRP2 is + * used to describe a larger data buffer.

The PRP list will be contiguous. + + * The native SGL for NVMe devices is a Physical Region Page (PRP). A PRP + * consists of a list of PRP entries to describe a number of noncontigous + * physical memory segments as a single memory buffer, just as a SGL does. Note + * however, that this function is only used by the IOCTL call, so the memory + * given will be guaranteed to be contiguous. There is no need to translate + * non-contiguous SGL into a PRP in this case.

PRP2 + * contains the second PRP element if the memory being described fits within 2 + * PRP entries, or a PRP list pointer if the PRP spans more than two entries. + * + * A PRP list pointer contains the address of a PRP list, structured as a linear + * array of PRP entries.
