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

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

77 | Select this option to enable shared memory partition support. | |

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