If the profiler behaves unexpectedly during the profiling session, or the profiling session fails to start, try the following steps:
Close the host application.
Restart the target device.
Start the host application and connect to the target device.
To enable logging on the host, refer to this config file:
Host-x86_64/nvlog.config.template
When reporting any bugs please include the build version number as described in
the Help → About dialog. If possible, attach log files and report
(.qdrep
) files, as they already contain necessary version information.
NVIDIA System Profiler uses a settings file (NVIDIA Tegra System Profiler.ini
)
on the host to store information about loaded projects, report files, window
layout configuration, etc. Location of the settings file is described in the
Help → About dialog. Deleting the settings file will restore
NVIDIA System Profiler to a fresh state, but all projects and reports will
disappear from the Project Explorer.
When connecting to an Android-based device, NVIDIA System Profiler installs its executable and library files into the following directory:
/data/local/tmp/com.nvidia.tegraprofiler.tools/
Logs on the target device are collected into this file:
/data/local/tmp/com.nvidia.tegraprofiler.tools/quadd_d.log
To enable verbose logging on the target device, follow these steps:
Close the host application.
Restart the target device.
From ADB shell, launch the following command:
/data/local/tmp/com.nvidia.tegraprofiler.tools/quadd_d --debug --msg_level=debug
On rooted Android devices, the command above should be started from superuser
(e.g., adb shell su -c ...
).
Start the host application and connect to the target device.
Please note that in some cases, debug logging can significantly slow down the profiler.
When connecting to a Linux-based device, NVIDIA System Profiler installs its executable and library files into the following directory:
/opt/nvidia/tegra_system_profiler/
Logs on the target devices are collected into this file:
/var/log/quadd_d.log
To enable verbose logging on the target device, follow these steps:
Close the host application.
Restart the target device.
From SSH console, launch the following command:
sudo /opt/nvidia/tegra_system_profiler/quadd_d --debug --msg_level=debug
Start the host application and connect to the target device.
Please note that in some cases debug logging can significantly slow down the profiler.
