2022-03-09 | cpufreq: amd-pstate: Add more tracepoint for AMD P-State module | Jinzhou Su | |
Add frequency, mperf, aperf and tsc in the trace. This can be used to debug and tune the performance of AMD P-state driver. Use the time difference between amd_pstate_update to calculate CPU frequency. There could be sleep in arch_freq_get_on_cpu, so do not use it here.
