gtop's Issues

"tegrastats was not found at the expected location ~/tegrastats"

Where can I change tegrastats location?

std::out_of_range exception

$ sudo ./gtop 
terminate called after throwing an instance of 'std::out_of_range'
                                                                    what():  vector::_M_range_check: __n (which is 1) >= this->size() (which is 1)

I built the code with $ g++ -std=c++14 gtop.cc utils.cc display.cc -o gtop -pedantic -Wall -Wextra -lncurses -lpthread -g
and gdb reveals:

This is on a Nvidia Jetson TX2 with ubuntu 16.04.03 and kernel 4.4.38

Core Dumped

I compiled gtop for jetson tx2 and I'm getting this output:

terminate called after throwing an instance of 'std::invalid_argument'
                                                                        what():  stoi

Report: fork zlacelle/gtop works fine, also with Jetson Nano

Reporting success with the fork https://github.com/zlacelle/gtop on my Jetson Nano with sudo gtop --tx2

Installation steps for that fork:

• Clone from git
• Modify gtop.hh as follows:

const std::string TEGRASTATS_PATH     = "/usr/bin/tegrastats";
const std::string TEGRASTATSFAKE_PATH = "/usr/local/bin/tegrastats_fake";

• Copy "fake" bin from source code to local: sudo cp tegrastats_fake /usr/local/bin
• Compile code with make
• Copy binary to local with sudo chown root: gtop; sudo mv gtop /usr/local/bin
• Add alias to .bashrc: alias gt='sudo gtop --tx2'

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!

weird graph icons. what am i missing?

i have these weird graph "lines" in gtop; i use this program since 10 years now and never saw that.
this is my regular user running gtop(arch,i3,urxvt,nvidia):

and this is a xterm try.
https://i.redd.it/ledt818hl7711.png

i did export LANG=en_US.utf8 and export TERM=xterm-256color and both are reported in printenv and started xterm or how am i supose to spawn it?
if i just run xterm afterwards it looks exactly the same as before.

have a nice day sir

DLA Support

Any ideas on how to measure DLA utilization on the AGX?
