214 MPS (Max Payload Size) and MRRS (Max Read Request Size) are PCIe
218 The following choices set the MPS and MRRS optimization strategy
231 Use the BIOS defaults; don't touch MPS at all. This is the same
238 Default choice; ensure that the MPS matches upstream bridge.
244 Use largest MPS that boot-time devices support. If you have a
246 will use the largest MPS that's supported by all devices. This
253 Use MPS and MRRS for best performance. Ensure that a given
254 device's MPS is no larger than its parent MPS, which allows us to
255 keep all switches/bridges to the max MPS supported by their
262 Set MPS = 128 for all devices. MPS configuration effected by the
263 other options could cause the MPS on one root port to be
264 different than that of the MPS on another, which may cause
265 hot-added devices or peer-to-peer DMA to fail. Set MPS to the
