Hi Martin,
I am trying to use your tool of GUI for Tegra TX1.
However I am getting the folling compilation warning

root@tegra-ubuntu:~/gstop/gtop-master# make
g++ -std=c++11 gtop.cc utils.cc display.cc -o gtop -pedantic -Wall -Wextra -lncurses -lpthread
gtop.cc:193:6: warning: unused parameter ‘d’ [-Wunused-parameter]
void display_stats(const dimensions & d, const tegrastats & ts) {

then when I execute the sudo ./gtop. I am getting the following error.
root@tegra-ubuntu:~/gstop/gtop-master# ./gtop
terminate called after throwing an instance of 'std::out_of_range'
what(): vector::_M_range_check
Aborted
Even I have increased the c
const int STATS_BUFFER_SIZE = 1024;

But still nothing works!

This is the output I get from the ~/tegrastats

Could you please help me fix this problem.

Thanks!

Increasing the buffer size is required from R28.2 that logs almost double information with temperatures.
For TX1 on R28.1, cpu index should be 5 and gpu index 7. Note that enabling swap would need to increase these.
The gtop.cc version provided in #1 handles swap (as long as swap info format doesn't change).
If you want to make a new branch with a clean implementation, it would be nice.
It would probably be better to check for keywords (although these change among versions) rather than relying on indexes. I just did that trial and shared as a starting point for anyone it would help, but this may for sure be improved.

Hi HoneyPatouceul,

I am now using the TX2 with 3.2 Jetpack, could you please tell me how to use this gtop.
This is my output

I am getting some error when I use the $sudo ./gtop

Thanks,
