So it is important to show minimum features to use base-freq and turbo-freq features. Here the change are: - When there is no support of CONFIG_TDP_GET_LEVELS_INFO, then instead of treating this as fatal error, treat this with number of config levels = 0, that means only base level 0 is present. - There is no support of mail box commands to get base frequencies or turbo frequencies.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AMD Zen 2 introduces the RDPRU instruction which can be used to access some processor registers which are typically only accessible in privilege level 0. ECX specifies the register to read and EDX:EAX will contain the value read. ECX: 0 - Register MPERF 1 - Register APERF This has the added advantage of not having to use the msr module, since the userspace to kernel transitions which occur during each read_msr() might cause APERF and MPERF to go out of sync.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The per_cpu_schedule flag is used to move the cpupower process to the cpu on which we are looking to read the APERF/MPERF registers. This prevents IPIs from being generated by read_msr()s as we are already on the cpu of interest. Ex: If cpupower is running on CPU 0 and we execute read_msr(20, MSR_APERF, val) then, read_msr(20, MSR_MPERF, val) the msr module will generate an IPI from CPU 0 to CPU 20 to query for the MSR_APERF and then the MSR_MPERF in separate IPIs. This delay, caused by IPI latency, between reading the APERF and MPERF registers may cause both of them to go out of sync. The use of the per_cpu_schedule flag reduces the probability of this from happening. It comes at the cost of a negligible increase in cpu consumption caused by the migration of cpupower across each of the cpus of the system.
