469 | The channel interface driver allows applications to communicate | |
470 | with iLO/iLO2 management processors present on HP ProLiant | |
471 | servers. Upon loading, the driver creates /dev/hpilo/dXccbN files, | |
472 | which can be used to gather data from the management processor, | |
473 | via read and write system calls. | |

475 | To compile this driver as a module, choose M here: the | |
476 | module will be called hpilo. | |

484 | The GRU is a hardware resource located in the system chipset. The GRU | |

487 | scatter/gather, bcopy, AMOs, etc. The GRU is directly accessed by user | |
488 | instructions using user virtual addresses. GRU instructions (ex., bcopy) use | |
