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