When I run tegrastats I don’t see any GPU info. Am I missing a package or something?
I see:
RAM 635/3854MB (lfb 617x4MB) SWAP 0/0MB (cached 0MB) cpu [6%,7%,9%,5%]@-1 VDE 0 EDP limit 0
Dusty said we should see:
RAM 129/3854MB (lfb 781x4MB) SWAP 0/0MB (cached 0MB) cpu [2%,0%,0%,0%]@102 EMC 5%@40 AVP 3%@80 VDE 0 GR3D 0%@38 EDP limit 1912
where
EMC – memory controller
AVP – audio/video processor
VDE – video decoder engine
GR3D – GPU
Just curious,

Try running it with sudo privilege, it should report… For additional info you can also poke around these directories:
/sys/kernel/debug/gpu.0
/sys/kernel/debug/gpu.0_scaling
/sys/kernel/debug/clock/gbus
/sys/kernel/debug/clock/emc
Due to the permissions you’ll likely need to use sudo. For example:
ubuntu@tegra-ubuntu:~$ sudo ls /sys/kernel/debug/gpu.0
[sudo] password for ubuntu:

cde_ctx_count_top gr_idle_timeout_default_us pll_reg_raw

There is a lot you can play around with in /sys/kernel/debug (doesn’t hurt to sudo cat anything that looks interesting), however debugfs is subject to change.
