72 bool "Use 64K pages to map SPE local store"
73 # we depend on PPC_MM_SLICES for now rather than selecting
74 # it because we depend on hugetlbfs hooks being present. We
75 # will fix that when the generic code has been improved to
76 # not require hijacking hugetlbfs hooks.
77 depends on SPU_FS && PPC_MM_SLICES && !PPC_64K_PAGES
79 select PPC_HAS_HASH_64K
81 This option causes SPE local stores to be mapped in process
82 address spaces using 64K pages while the rest of the kernel
83 uses 4K pages. This can improve performances of applications
84 using multiple SPEs by lowering the TLB pressure on them.

130 Select this, if you want to use the PMI interface
131 to switch frequencies. Using PMI, the
132 processor will not only be able to run at lower speed,
133 but also at lower core voltage.

145 PMI (Platform Management Interrupt) is a way to
146 communicate with the BMC (Baseboard Management Controller).
147 It is used in some IBM Cell blades.
149 config CBE_CPUFREQ_SPU_GOVERNOR
150 tristate "CBE frequency scaling based on SPU usage"
151 depends on SPU_FS && CPU_FREQ
154 This governor checks for spu usage to adjust the cpu frequency.
155 If no spu is running on a given cpu, that cpu will be throttled to
156 the minimal possible frequency.
