Hi,

I am not sure what else is missing in my kernel configuration to enable cpufreq, following is my kernel configuration is exactly same as given in one of the previous threads.

CONFIG_ARCH_HAS_CPUFREQ=y
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=y
CONFIG_CPU_FREQ_GOV_COMMON=y
CONFIG_CPU_FREQ_STAT=y
CONFIG_CPU_FREQ_STAT_DETAILS=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_POWERSAVE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=y
CONFIG_CPU_FREQ_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_ONDEMAND=y
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y
CONFIG_GENERIC_CPUFREQ_CPU0=y
# CONFIG_ARM_KIRKWOOD_CPUFREQ is not set
CONFIG_ARM_OMAP2PLUS_CPUFREQ=y

but still sys/devices/system/cpu/cpu0/cpufreq/scaling_governor is not getting created.

Please help me to find what I am missing.

Thanks,

Prabhak
