13 select PPC_PCI_CHOICE if EMBEDDED
17 depends on PPC_PSERIES
18 bool "Support for shared-processor logical partitions"
21 Enabling this option will make the kernel run more efficiently
22 on logically-partitioned pSeries systems which use shared
23 processors, that is, which share physical processors between
24 two or more partitions.
27 bool "PCI Extended Error Handling (EEH)" if EMBEDDED
28 depends on PPC_PSERIES && PCI

41 bool "LPAR Configuration Data"
42 depends on PPC_PSERIES || PPC_ISERIES
44 Provide system capacity information via human readable
45 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface.

48 depends on PPC_PSERIES && PPC_EARLY_DEBUG
49 bool "Enable extra debug logging in platforms/pseries"
53 bool "Support for shared-memory logical partitions"
54 depends on PPC_PSERIES
58 Select this option to enable shared memory partition support.
59 With this option a system running in an LPAR can be given more
60 memory than physically available and will allow firmware to
61 balance memory across many LPARs.
64 tristate "Collaborative memory management"
68 Select this option, if you want to enable the kernel interface
69 to reduce the memory size of the system. This is accomplished
70 by allocating pages of memory and put them "on hold". This only
71 makes sense for a system running in an LPAR where the unused pages
72 will be reused for other LPARs. The interface allows firmware to
73 balance memory across many LPARs.
76 bool "Dispatch Trace Log"
77 depends on PPC_SPLPAR && DEBUG_FS
79 SPLPAR machines can log hypervisor preempt & dispatch events to a
80 kernel buffer. Saying Y here will enable logging these events,
81 which are accessible through a debugfs file.
83 Say N if you are unsure.
