3 bool "IBM pSeries & new (POWER5-based) iSeries"
8 select RTAS_ERROR_LOGGING
11 select PPC_PCI_CHOICE if EMBEDDED
15 depends on PPC_PSERIES
16 bool "Support for shared-processor logical partitions"
19 Enabling this option will make the kernel run more efficiently
20 on logically-partitioned pSeries systems which use shared
21 processors, that is, which share physical processors between
22 two or more partitions.
25 bool "PCI Extended Error Handling (EEH)" if EMBEDDED
26 depends on PPC_PSERIES && PCI
27 default y if !EMBEDDED
31 depends on PCI_MSI && EEH
35 tristate "Scanlog dump interface"
36 depends on RTAS_PROC && PPC_PSERIES
39 bool "LPAR Configuration Data"
40 depends on PPC_PSERIES || PPC_ISERIES
42 Provide system capacity information via human readable
43 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface.
45 config PPC_PSERIES_DEBUG
46 depends on PPC_PSERIES && PPC_EARLY_DEBUG
47 bool "Enable extra debug logging in platforms/pseries"
51 bool "Support for shared-memory logical partitions"
52 depends on PPC_PSERIES
56 Select this option to enable shared memory partition support.
57 With this option a system running in an LPAR can be given more
58 memory than physically available and will allow firmware to
59 balance memory across many LPARs.
62 tristate "Collaborative memory management"
63 depends on PPC_SMLPAR && !CRASH_DUMP
66 Select this option, if you want to enable the kernel interface
67 to reduce the memory size of the system. This is accomplished
68 by allocating pages of memory and put them "on hold". This only
69 makes sense for a system running in an LPAR where the unused pages
70 will be reused for other LPARs. The interface allows firmware to
71 balance memory across many LPARs.
74 bool "Dispatch Trace Log"
75 depends on PPC_SPLPAR && DEBUG_FS
77 SPLPAR machines can log hypervisor preempt & dispatch events to a
78 kernel buffer. Saying Y here will enable logging these events,
79 which are accessible through a debugfs file.
81 Say N if you are unsure.
