At least on sdm850, the 2956800 khz is detected as a boost frequency in function qcom_cpufreq_hw_read_lut(). Let's enable boost support by calling cpufreq_enable_boost_support(), so that we can get the boost frequency by switching it on via 'boost' sysfs entry like below. $ echo 1 > /sys/devices/system/cpu/cpufreq/boost Signed-off-by: Shawn Guo <shawn.guo@linaro.org> --- drivers/cpufreq/qcom-cpufreq-hw.c | 6 ++++++ 1 file changed, 6 insertions(+)
