Core Dumped

[Davidnet]

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

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

@martinkersner encountered the same error on TX2. Is there something that can be done about it?
@Davidnet were you able to resolve the issue?

[martinkersner]

@ankitdhall tegrastats output format apparently changed, parsing has to be done differently now. I don't have TX2 anymore, so I can't fix it.

@martinkersner The output on TX2 platform is shown below, hope it helps.

Hi. I also using jetson TX2 and found the solution for this problem.
In my case the Error occurs at line 133 at gtop.cc.

    case TX2:
      get_cpu_stats_tx2(ts, stats.at(5));
      get_gpu_stats(ts, stats.at(13)); // this part causes the error!
      break;

Since the output from the sudo ~/tegrastats are like @jh01231230 shows, you'll see the 14th token doesn't exist in the token structure stats.
For watching GPU usage properly, change the line 133 in gtop.cc like below:

    case TX2:
      get_cpu_stats_tx2(ts, stats.at(5));
      get_gpu_stats(ts, stats.at(11)); // changed this part
      break;

I've created a pull request that fixes these issues. The problem is that we're trying to automatically identify the board type based on the argument structure. Now, you can specify on the command line, and it should work. Still needs testing on the TX1 and TK1.

[dhingratul]

@zlacelle Did you also include Jetson AGX support ?

[zlacelle]

I unfortunately do not have an AGX, so I did not.

[alexis-gruet-deel]

I've created a PR for Xavier. I have some doubts w/ this :

if (stats.size() >= 15 && stats.size() <30) //Don't have TX* to test.. 
    ts.version = TX1;
  else if(stats.size() >=30)
    ts.version = AGX;
  else
    ts.version = TX2;

I let You check. anyway it works well now.

For a minit device I had to change the fields in order to get it working. I think it is a NVIDIA AGX card, but the suggested settings of @MI-LA01 do not work for me.

I change the field numbers from 5,9 to 9 and 13: https://github.com/MI-LA01/gtop/compare/master...mdehollander:minit?expand=1
