21 | Enabling this option will make the kernel run more efficiently | |
22 | on logically-partitioned pSeries systems which use shared | |
23 | processors, that is, which share physical processors between | |
24 | two or more partitions. | |

01cf6fe8 NA |
60 | help |
61 | Say Y here if you want the pseries core to produce a bunch of | |
62 | debug messages to the system log. Select this if you are having a | |
63 | problem with the pseries core and want to see more of what is | |
64 | going on. This does not enable debugging in lpar.c, which must | |
65 | be manually done due to its verbosity. | |

74 | Select this option to enable shared memory partition support. | |
75 | With this option a system running in an LPAR can be given more | |
76 | memory than physically available and will allow firmware to | |
77 | balance memory across many LPARs. | |

82 | default y |
83 | help | |
84 | Select this option, if you want to enable the kernel interface | |
85 | to reduce the memory size of the system. This is accomplished | |
86 | by allocating pages of memory and put them "on hold". This only | |
87 | makes sense for a system running in an LPAR where the unused pages | |
88 | will be reused for other LPARs. The interface allows firmware to | |
89 | balance memory across many LPARs. | |

94 | help | |
95 | SPLPAR machines can log hypervisor preempt & dispatch events to a | |

97 | which are accessible through a debugfs file. | |
