  28           on logically-partitioned pSeries systems which use shared

  60         help
  61           Select this option, if you want to enable support for IO Event
  62           interrupts. IO event interrupt is a mechanism provided by RTAS
  63           to return information about hardware error and non-error events
  64           which may need OS attention. RTAS returns events for multiple
  65           event types and scopes. Device drivers can register their handlers
  66           to receive events.
  67
  68           This option will only enable the IO event platform code. You
  69           will still need to enable or compile the actual drivers
  70           that use this infrastruture to handle IO event interrupts.

  86           debug messages to the system log. Select this if you are having a
  87           problem with the pseries core and want to see more of what is
  88           going on. This does not enable debugging in lpar.c, which must

  99           With this option a system running in an LPAR can be given more
 100           memory than physically available and will allow firmware to

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