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

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

  56. default y
  57. help
  58. Select this option, if you want to enable the kernel interface
  59. to reduce the memory size of the system. This is accomplished
  60. by allocating pages of memory and put them "on hold". This only
  61. makes sense for a system running in an LPAR where the unused pages
  62. will be reused for other LPARs. The interface allows firmware to
  63. balance memory across many LPARs.

  67. help
  68. SPLPAR machines can log hypervisor preempt & dispatch events to a
  69. kernel buffer. Saying Y here will enable logging these events,
  70. which are accessible through a debugfs file.
  71. Say N if you are unsure.
