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

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

65 | help | |
66 | Select this option, if you want to enable the kernel interface | |
67 | to reduce the memory size of the system. This is accomplished | |
68 | by allocating pages of memory and put them "on hold". This only | |
69 | makes sense for a system running in an LPAR where the unused pages | |
70 | will be reused for other LPARs. The interface allows firmware to | |
71 | balance memory across many LPARs. | |
