3 bool "IBM pSeries & new (POWER5-based) iSeries"
7 select RTAS_ERROR_LOGGING
10 select PPC_PCI_CHOICE if EMBEDDED
14 depends on PPC_PSERIES
15 bool "Support for shared-processor logical partitions"
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.
24 bool "PCI Extended Error Handling (EEH)" if EMBEDDED
25 depends on PPC_PSERIES && PCI
26 default y if !EMBEDDED
30 depends on PCI_MSI && EEH
34 tristate "Scanlog dump interface"

41 Provide system capacity information via human readable
42 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface.
44 config PPC_PSERIES_DEBUG
45 depends on PPC_PSERIES && PPC_EARLY_DEBUG
46 bool "Enable extra debug logging in platforms/pseries"
50 bool "Support for shared-memory logical partitions"
51 depends on PPC_PSERIES
55 Select this option to enable shared memory partition support.
56 With this option a system running in an LPAR can be given more
57 memory than physically available and will allow firmware to
58 balance memory across many LPARs.
61 tristate "Collaborative memory management"
62 depends on PPC_SMLPAR && !CRASH_DUMP
65 Select this option, if you want to enable the kernel interface
66 to reduce the memory size of the system. This is accomplished
67 by allocating pages of memory and put them "on hold". This only
68 makes sense for a system running in an LPAR where the unused pages
69 will be reused for other LPARs. The interface allows firmware to
70 balance memory across many LPARs.
73 bool "Dispatch Trace Log"
74 depends on PPC_SPLPAR && DEBUG_FS
76 SPLPAR machines can log hypervisor preempt & dispatch events to a
77 kernel buffer. Saying Y here will enable logging these events,
78 which are accessible through a debugfs file.
80 Say N if you are unsure.
