| * _base_build_nvme_prp - This function is called for NVMe end devices to build |

| * @data_out_dma: physical address for WRITES |
| * @data_out_sz: data xfer size for WRITES |
| * @data_in_dma: physical address for READS |
| * @data_in_sz: data xfer size for READS |
| * |
| * The native SGL is built starting in the first PRP |
| * entry of the NVMe message (PRP1). If the data buffer is small enough to be |
| * described entirely using PRP1, then PRP2 is not used. If needed, PRP2 is |
| * used to describe a larger data buffer. If the data buffer is too large to |
| * describe using the two PRP entriess inside the NVMe message, then PRP1 |
| * describes the first data memory segment, and PRP2 contains a pointer to a PRP |
| * list located elsewhere in memory to describe the remaining data memory |
| * segments. 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. All PRPs will describe |
| * contiguous space that is one page size each. |
| * |
| * Each NVMe message contains two PRP entries. The first (PRP1) either contains |
| * a PRP list pointer or a PRP element, depending upon the command. 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. Each PRP entry in this list describes a segment of |
| * physical memory. |
| * |
| * Each 64-bit PRP entry comprises an address and an offset field. The address |
| * always points at the beginning of a 4KB physical memory page, and the offset |
| * describes where within that 4KB page the memory segment begins. Only the |
| * first element in a PRP list may contain a non-zero offset, implying that all |
| * memory segments following the first begin at the start of a 4KB page. |
| * |
| * Each PRP element normally describes 4KB of physical memory, with exceptions |
| * for the first and last elements in the list. If the memory being described |
| * by the list begins at a non-zero offset within the first 4KB page, then the |
| * first PRP element will contain a non-zero offset indicating where the region |
| * begins within the 4KB page. The last memory segment may end before the end |
| * of the 4KB segment, depending upon the overall size of the memory being |
| * described by the PRP list. |
| * |
| * Since PRP entries lack any indication of size, the overall data buffer length |
| * is used to determine where the end of the data memory buffer is located, and |
| * how many PRP entries are required to describe it. |
