Additional Features of the OS Image 

NVIDIA PerfHUD ES Support 

The supplied OS images support the latest version of NVIDIA’s PerfHUD ES, available from the 

developer website.  However, by default, this support is disabled.  To enable it (and later 

disable it if desired), do the following: 

Enable/Disable on Windows Host 

1)

 

Open an explorer window to Start Menu: All Programs: NVIDIA Corporation: Ventana 
Android Gingerbread: Version <XXXXXXXX>: Platform Directory 

2)

 

Navigate to the sub-directory: 

perfhud_switch

 

3)

 

Ensure that your devkit is connected to the Host PC via ADB 

4)

 

Run the 

enable_perfhud.bat

 batch file, which will enable PerfHUD ES support and 

reboot your devkit.  This support will stay enabled across reboots until manually 
disabled or the board is re-flashed. 

To manually disable PerfHUD ES support, follow these instructions using the 

disable_perfhud.bat

 script 

Enable/Disable on Linux Host 

1)

 

Open a shell to the 

perfhud_switch

  subdirectory of the OS installer pack 

2)

 

Ensure that your devkit is connected to the Host PC via ADB 

3)

 

Run the 

enable_perfhud.sh

 script, which will enable PerfHUD ES support and 

reboot your devkit.  This support will stay enabled across reboots until manually 
disabled or the board is re-flashed. 

To manually disable PerfHUD ES support, follow these instructions using the 

disable_perfhud.sh

 script 

OProfile Support 

The OProfile performance tool is not supported by this OS image. 

Perf Support 

The “

perf

” performance tool is supported by this OS image, and the on-device “

perf

” 

application is included in 

/system/bin

.  It is thus in the 

adb shell

 path.  See the NVIDIA 

Tegra Developers website for details on how to use the 

perf

 tool.
