Hi All,

  1. I observe some difference in sudo ./tegrastats output between 5.1.6.1 and 5.2
    Output on 5.2 -
    01-13-2022 10:37:47 RAM 2861/28305MB (lfb 111x4MB) CPU [0%@1817,0%@1817,0%@1817,0%@1817,100%@1817,0%@1817,0%@1817] EMC_FREQ @2133 GR3D_FREQ 0%@1109 APE 245 GR3D_PCI % 0% AUX@32C CPU@32C Tdiode@31.75C AO@32.5C GPU@32.5C tj@42.5C
    on 5.1.6.1
    RAM 731/27924MB (lfb 6597x4MB) CPU [0%,0%,0%,0%,1%,0%] EMC_FREQ @2133 GR3D_FREQ 0%@1109 APE 245 GR3D_PCI % 0% AUX@32.5C CPU@33.5C Tdiode@33.75C AO@34C GPU@33.5C tj@43C

Is it possible to get tegrastats to report cpu frequencies on 5.1.6.1?

  1. How do we disable DVFS and frequency scaling completely for every module on the SoC? We would like to run cpu, gpu, mem at max frequency. From my tegrastat output on 5.2 above I gather that CPU freq is 1.8GHz - But I think the soc’s CPUs are speced to go upto 2.2GHz.

Thanks.

Hi, @ai.trucker

Will executing tegrastats as the superuser with sudo help?

Please refer to How to set maximum CPU/GPU frequency?.
