tegrastats log information in L4T 28.2.1

Hi,

My Jetson TX2 is running on L4T 28.2.1. On running the tegrastats, the output is as below:

RAM 1385/7846MB (lfb 1283x4MB) CPU [1%@345,off,off,1%@345,0%@345,1%@345] BCPU@34.5C MCPU@34.5C GPU@34C PLL@34.5C Tboard@32C Tdiode@32.75C PMIC@100C thermal@34.6C VDD_IN 2346/2365 VDD_CPU 153/153 VDD_GPU 153/153 VDD_SOC 384/384 VDD_WIFI 306/306 VDD_DDR 230/239

From CPU field, I see 6 cores(2 of Nvidia Denver and 4 of ARM cortex A57). The documentation of Tegrastats utility does not specify the order of cores in CPU [1%@345,off,off,1%@345,0%@345,1%@345].

Also, I don’t find fields related to GPU usage statistic. The tegrastats output above does not have ‘GR3D’ field.

Can anyone help me understand this?

shrinath.j,

Did you run the tegrastats as root?

Thanks WayneWWW. Running as root did the job.

But could you tell me the order of CPU cores usage field? Which values are for Denver cores and A57 cores among [1%@345,off,off,1%@345,0%@345,1%@345]?

The Denver cores are the 2nd and 3rd ones printed out - the ones that say ‘off’. The others are the A57’s.
The Denver cores are off by default to save power - you can enable them with nvpmodel utility.

Is VDD_IN the total power consumption of TX2?

Does VDD_IN include VDD_CPU, VDD_GPU, VDD_SOC, VDD_WIFI and VDD_DDR ?
