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

99 config PPC_IBM_CELL_RESETBUTTON
100 bool "IBM Cell Blade Pinhole reset button"
101 depends on CBE_RAS && PPC_IBM_CELL_BLADE
104 Support Pinhole Resetbutton on IBM Cell blades.
105 This adds a method to trigger system reset via front panel pinhole button.
107 config PPC_IBM_CELL_POWERBUTTON
108 tristate "IBM Cell Blade power button"
109 depends on PPC_IBM_CELL_BLADE && INPUT_EVDEV
112 Support Powerbutton on IBM Cell blades.

129 config CBE_CPUFREQ_PMI_ENABLE
130 bool "CBE frequency scaling using PMI interface"
131 depends on CBE_CPUFREQ && EXPERIMENTAL
134 Select this, if you want to use the PMI interface
135 to switch frequencies. Using PMI, the
136 processor will not only be able to run at lower speed,
137 but also at lower core voltage.
139 config CBE_CPUFREQ_PMI
141 depends on CBE_CPUFREQ_PMI_ENABLE
147 depends on CBE_CPUFREQ_PMI || PPC_IBM_CELL_POWERBUTTON
149 PMI (Platform Management Interrupt) is a way to
150 communicate with the BMC (Baseboard Management Controller).
151 It is used in some IBM Cell blades.
153 config CBE_CPUFREQ_SPU_GOVERNOR
154 tristate "CBE frequency scaling based on SPU usage"
155 depends on SPU_FS && CPU_FREQ
158 This governor checks for spu usage to adjust the cpu frequency.
159 If no spu is running on a given cpu, that cpu will be throttled to
160 the minimal possible frequency.
