Hello, Seems in cpufreq_userspace.c the userspace_mutex is common for all CPUs using userspace code to change cpu frequency and could possibly slow down the frequency change on all other cpus. Can we have per_cpu mutex so that access to one cpu does not hold up other cpus. Thanks, Praveen Sent by an employee of the Qualcomm Innovation Center, Inc.
