30 | Enabling this option will make the kernel run more efficiently | |
31 | on logically-partitioned pSeries systems which use shared | |
32 | processors, that is, which share physical processors between | |
33 | two or more partitions. | |

55 | bool "IO Event Interrupt support" | |
56 | depends on PPC_PSERIES | |
57 | default y | |
58 | help | |
59 | Select this option, if you want to enable support for IO Event | |
60 | interrupts. IO event interrupt is a mechanism provided by RTAS | |
61 | to return information about hardware error and non-error events | |
62 | which may need OS attention. RTAS returns events for multiple | |
63 | event types and scopes. Device drivers can register their handlers | |
64 | to receive events. | |
65 | ||
66 | This option will only enable the IO event platform code. You | |
67 | will still need to enable or compile the actual drivers | |
6b2aac42 | 68 | that use this infrastructure to handle IO event interrupts. |

83 | Say Y here if you want the pseries core to produce a bunch of | |
84 | debug messages to the system log. Select this if you are having a | |
85 | problem with the pseries core and want to see more of what is | |
86 | going on. This does not enable debugging in lpar.c, which must | |
87 | be manually done due to its verbosity. | |

105 | help | |
106 | Select this option, if you want to enable the kernel interface | |
107 | to reduce the memory size of the system. This is accomplished | |
108 | by allocating pages of memory and put them "on hold". This only | |
109 | makes sense for a system running in an LPAR where the unused pages | |
110 | will be reused for other LPARs. The interface allows firmware to | |
111 | balance memory across many LPARs. | |
