2225 * @data_in_dma: physical address for READS
2226 * @data_in_sz: data xfer size for READS
2228 * The native SGL is built starting in the first PRP
2229 * entry of the NVMe message (PRP1). If the data buffer is small enough to be
2230 * described entirely using PRP1, then PRP2 is not used. If needed, PRP2 is
2231 * used to describe a larger data buffer. If the data buffer is too large to
2232 * describe using the two PRP entriess inside the NVMe message, then PRP1
2233 * describes the first data memory segment, and PRP2 contains a pointer to a PRP
2234 * list located elsewhere in memory to describe the remaining data memory
2235 * segments. The PRP list will be contiguous.
2237 * The native SGL for NVMe devices is a Physical Region Page (PRP). A PRP
2238 * consists of a list of PRP entries to describe a number of noncontigous
2239 * physical memory segments as a single memory buffer, just as a SGL does. Note
2240 * however, that this function is only used by the IOCTL call, so the memory
2241 * given will be guaranteed to be contiguous. There is no need to translate
2242 * non-contiguous SGL into a PRP in this case. All PRPs will describe
2243 * contiguous space that is one page size each.
2245 * Each NVMe message contains two PRP entries. The first (PRP1) either contains
2246 * a PRP list pointer or a PRP element, depending upon the command. PRP2
2247 * contains the second PRP element if the memory being described fits within 2
2248 * PRP entries, or a PRP list pointer if the PRP spans more than two entries.
2250 * A PRP list pointer contains the address of a PRP list, structured as a linear
2251 * array of PRP entries. Each PRP entry in this list describes a segment of
2254 * Each 64-bit PRP entry comprises an address and an offset field. The address
2255 * always points at the beginning of a 4KB physical memory page, and the offset
2256 * describes where within that 4KB page the memory segment begins. Only the
2257 * first element in a PRP list may contain a non-zero offset, implying that all
2258 * memory segments following the first begin at the start of a 4KB page.
2260 * Each PRP element normally describes 4KB of physical memory, with exceptions
2261 * for the first and last elements in the list. If the memory being described
2262 * by the list begins at a non-zero offset within the first 4KB page, then the
2263 * first PRP element will contain a non-zero offset indicating where the region
2264 * begins within the 4KB page. The last memory segment may end before the end
2265 * of the 4KB segment, depending upon the overall size of the memory being
2266 * described by the PRP list.
2268 * Since PRP entries lack any indication of size, the overall data buffer length
2269 * is used to determine where the end of the data memory buffer is located, and
2270 * how many PRP entries are required to describe it.
