https://bugzilla.kernel.org/show_bug.cgi?id=81131 Bug ID: 81131 Summary: Not found this subsystem directory /sys/devices/system/cpu/cpufreq Product: Power Management Version: 2.5 Kernel Version: 3.15.6 Hardware: ARM OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: cpufreq Assignee: cpufreq@xxxxxxxxxxxxxxx Reporter: no111u3@xxxxxxxxx Regression: No My board is XAM3359-Beaglebone Black. I'm using specify utils - cpufrequtils, but in new kernel 3.15.6 this util's can't work: control directory in sysfs /sys/devices/system/cpu/cpufreq does not exists. My configuration for cpufreq in this kernel: jane linux-3.15.6 # cat .config | grep -i freq CONFIG_ARCH_HAS_CPUFREQ=y # CPU Frequency scaling CONFIG_CPU_FREQ=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=m CONFIG_CPU_FREQ_GOV_USERSPACE=m CONFIG_CPU_FREQ_GOV_ONDEMAND=y CONFIG_CPU_FREQ_GOV_CONSERVATIVE=m # ARM CPU frequency scaling drivers # CONFIG_ARM_KIRKWOOD_CPUFREQ is not set CONFIG_ARM_OMAP2PLUS_CPUFREQ=y CONFIG_PM_DEVFREQ=y # DEVFREQ Governors CONFIG_DEVFREQ_GOV_SIMPLE_ONDEMAND=m CONFIG_DEVFREQ_GOV_PERFORMANCE=m CONFIG_DEVFREQ_GOV_POWERSAVE=m CONFIG_DEVFREQ_GOV_USERSPACE=m # DEVFREQ Drivers This config is analogie to config for oldest patched kernels (3.8.13, 3.13.6+) but not working. -- You are receiving this mail because: You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
