3 bool "IBM pSeries & new (POWER5-based) iSeries"
4 select HAVE_PCSPKR_PLATFORM
16 select PPC_RTAS_DAEMON
17 select RTAS_ERROR_LOGGING
28 depends on PPC_PSERIES
29 bool "Support for shared-processor logical partitions"
32 Enabling this option will make the kernel run more efficiently
33 on logically-partitioned pSeries systems which use shared
34 processors, that is, which share physical processors between
35 two or more partitions.
38 bool "Dispatch Trace Log"
39 depends on PPC_SPLPAR && DEBUG_FS
41 SPLPAR machines can log hypervisor preempt & dispatch events to a
42 kernel buffer. Saying Y here will enable logging these events,
43 which are accessible through a debugfs file.
45 Say N if you are unsure.
48 tristate "pSeries energy management capabilities driver"
49 depends on PPC_PSERIES
52 Provides interface to platform energy management capabilities
53 on supported PSERIES platforms.
54 Provides: /sys/devices/system/cpu/pseries_(de)activation_hint_list
55 and /sys/devices/system/cpu/cpuN/pseries_(de)activation_hint
58 tristate "Scanlog dump interface"
59 depends on RTAS_PROC && PPC_PSERIES
62 bool "IO Event Interrupt support"
63 depends on PPC_PSERIES
66 Select this option, if you want to enable support for IO Event
67 interrupts. IO event interrupt is a mechanism provided by RTAS
68 to return information about hardware error and non-error events
69 which may need OS attention. RTAS returns events for multiple
70 event types and scopes. Device drivers can register their handlers
73 This option will only enable the IO event platform code. You
74 will still need to enable or compile the actual drivers
75 that use this infrastructure to handle IO event interrupts.
77 Say Y if you are unsure.
80 bool "LPAR Configuration Data"
81 depends on PPC_PSERIES
83 Provide system capacity information via human readable
84 <key word>=<value> pairs through a /proc/ppc64/lparcfg interface.
86 config PPC_PSERIES_DEBUG
87 depends on PPC_PSERIES && PPC_EARLY_DEBUG
88 bool "Enable extra debug logging in platforms/pseries"
90 Say Y here if you want the pseries core to produce a bunch of
91 debug messages to the system log. Select this if you are having a
92 problem with the pseries core and want to see more of what is
93 going on. This does not enable debugging in lpar.c, which must
94 be manually done due to its verbosity.
98 bool "Support for shared-memory logical partitions"
99 depends on PPC_PSERIES
103 Select this option to enable shared memory partition support.
104 With this option a system running in an LPAR can be given more
105 memory than physically available and will allow firmware to
106 balance memory across many LPARs.
109 tristate "Collaborative memory management"
110 depends on PPC_SMLPAR
113 Select this option, if you want to enable the kernel interface
114 to reduce the memory size of the system. This is accomplished
115 by allocating pages of memory and put them "on hold". This only
116 makes sense for a system running in an LPAR where the unused pages
117 will be reused for other LPARs. The interface allows firmware to
118 balance memory across many LPARs.
121 bool "Hypervisor supplied PMU events (24x7 & GPCI)"
123 depends on PERF_EVENTS && PPC_PSERIES
125 Enable access to hypervisor supplied counters in perf. Currently,
126 this enables code that uses the hcall GetPerfCounterInfo and 24x7
127 interfaces to retrieve counters. GPCI exists on Power 6 and later
128 systems. 24x7 is available on Power 8 and later systems.
133 depends on PPC_PSERIES
138 depends on PPC_PSERIES && !CPU_LITTLE_ENDIAN
139 bool "Support for GX bus based adapters"
141 Bus device driver for GX bus based adapters.
