How to calculate the "GPU RAM usage"? #28

Hi there, I'm very interested in your project. After reading the source code, I found that the "GPU RAM usage" item was calculate by running command of "intel_gpu_top -l" and parsing the output. But i was wondering how to get the GPU RAM from the output like outputs as follows:

Freq MHz IRQ RC6 Power W IMC MiB/s RCS/0 BCS/0 VCS/0 VECS/0 req act /s % gpu pkg rd wr % se wa % se wa % se wa % se wa 0 0 0 100 0.00 0.00 748 135 0.00 0 0 0.00 0 0 0.00 0 0 0.00 0 0 18 18 26 98 0.03 2.53 402 80 0.84 0 0 0.00 0 0 0.00 0 0 0.00 0 0 16 16 32 97 0.04 2.57 472 120 1.07 0 0 0.00 0 0 0.00 0 0 0.00 0 0

thanks, any reply will be appreciated.

hi, there is no GPU RAM usage calculated from this output, and AFAIK there is no way to extract this from the intel drivers (https://gitlab.freedesktop.org/drm/intel/-/issues/5018) so i have no idea where that info come from
