62 Units on machines implementing the Broadband Processor
66 bool "Use 64K pages to map SPE local store"
67 # we depend on PPC_MM_SLICES for now rather than selecting
68 # it because we depend on hugetlbfs hooks being present. We
69 # will fix that when the generic code has been improved to
70 # not require hijacking hugetlbfs hooks.
71 depends on SPU_FS && PPC_MM_SLICES && !PPC_64K_PAGES
73 select PPC_HAS_HASH_64K
75 This option causes SPE local stores to be mapped in process
76 address spaces using 64K pages while the rest of the kernel
77 uses 4K pages. This can improve performances of applications
78 using multiple SPEs by lowering the TLB pressure on them.
81 tristate "SPU event tracing support"
82 depends on SPU_FS && MARKERS
84 This option allows reading a trace of spu-related events through
85 the sputrace file in procfs.

96 config PPC_IBM_CELL_RESETBUTTON
97 bool "IBM Cell Blade Pinhole reset button"
98 depends on CBE_RAS && PPC_IBM_CELL_BLADE
101 Support Pinhole Resetbutton on IBM Cell blades.
102 This adds a method to trigger system reset via front panel pinhole button.
104 config PPC_IBM_CELL_POWERBUTTON
105 tristate "IBM Cell Blade power button"
106 depends on PPC_IBM_CELL_BLADE && INPUT_EVDEV
109 Support Powerbutton on IBM Cell blades.
110 This will enable the powerbutton as an input device.

115 depends on CBE_RAS && SPU_BASE
118 tristate "CBE frequency scaling"
119 depends on CBE_RAS && CPU_FREQ
122 This adds the cpufreq driver for Cell BE processors.
123 For details, take a look at <file:Documentation/cpu-freq/>.
124 If you don't have such processor, say N
126 config CBE_CPUFREQ_PMI_ENABLE
127 bool "CBE frequency scaling using PMI interface"
128 depends on CBE_CPUFREQ && EXPERIMENTAL
131 Select this, if you want to use the PMI interface
132 to switch frequencies. Using PMI, the
133 processor will not only be able to run at lower speed,
134 but also at lower core voltage.
136 config CBE_CPUFREQ_PMI
138 depends on CBE_CPUFREQ_PMI_ENABLE
144 depends on CBE_CPUFREQ_PMI || PPC_IBM_CELL_POWERBUTTON
146 PMI (Platform Management Interrupt) is a way to
147 communicate with the BMC (Baseboard Management Controller).
148 It is used in some IBM Cell blades.
150 config CBE_CPUFREQ_SPU_GOVERNOR
151 tristate "CBE frequency scaling based on SPU usage"
152 depends on SPU_FS && CPU_FREQ
155 This governor checks for spu usage to adjust the cpu frequency.
156 If no spu is running on a given cpu, that cpu will be throttled to
157 the minimal possible frequency.
