  53. help
  54. Select this option, if you want to enable support for IO Event
  55. interrupts. IO event interrupt is a mechanism provided by RTAS
  56. to return information about hardware error and non-error events
  57. which may need OS attention. RTAS returns events for multiple
  58. event types and scopes. Device drivers can register their handlers
  59. to receive events.
  60. This option will only enable the IO event platform code. You
  61. will still need to enable or compile the actual drivers
  62. that use this infrastruture to handle IO event interrupts.
  63. Say Y if you are unsure.

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

  86. Select this option to enable shared memory partition support.
  87. With this option a system running in an LPAR can be given more
  88. memory than physically available and will allow firmware to
  89. balance memory across many LPARs.

  94. help
  95. Select this option, if you want to enable the kernel interface
  96. to reduce the memory size of the system. This is accomplished
  97. by allocating pages of memory and put them "on hold". This only
  98. makes sense for a system running in an LPAR where the unused pages
  99. will be reused for other LPARs. The interface allows firmware to
  100. balance memory across many LPARs.
