This chapter describes the options available in the PerfHUD menu bar.
Open a custom XML file. Users rarely need to do this because the
perfhudes.xml in Linux, is automatically opened at startup. For more information, see Session File XML. Ctrl+O for shortcut.
Save the current settings to a custom XML file. Users rarely need to do this because the
perfhudes.xml in Linux, is always automatically updated when closing the PerfHUD host. Ctrl+S for shortcut.
Connect to a target device which is already available from ActiveSync. For example, AP15 with WinCE6 should use this one. ActiveSync and TCP/IP are two available connection types for Tegra. The system will use ActiveSync by default. When you didn’t have ActiveSync installed, you may see an error message box for initialization. If you only have TCP/IP connection, just click OK and use “IP Address” connection instead. Ctrl+A for shortcut.
Connect to a target device over TCP/IP. This could be used when a direct TCP/IP connection exists between host and target. If you manually change the connection type to TCP/IP, you are not allowed to switch back to ActiveSync connection. Ctrl+I for shortcut.
Manually reset the connection. Users rarely need to do this because the host automatically “times out” when an error condition occurs. F5 for shortcut.
Closes the PerfHUD host.
Toggle visibility of the vertical pane on the left.
Toggle visibility of the status pane on the bottom.
If desired, the resource upload lights can be accompanied by an audible clicking sound.
This is an alternative style for line graphs that uses a “square wave” type of pattern.
If enabled, the heartbeat graphs lag slightly behind real time, but they scroll by in a more regular and smooth fashion.
If connected to a device, this menu item brings up a dialog box that shows various information about the target device, e.g., the version of OpenGL ES and which extensions are supported.
Change the method used to render images in Frame Scrubber.
glReadPixelsto capture an actual bitmap of the frame buffer. This method is slower than ES Emulation, but more accurate.
When enabled, the host automatically switches from Performance Dashboard to Frame Debugger when a GL error occurs.
When enabled, the mode switches to Frame Debugger after a given number of frames (i.e., buffer swaps), where frame 1 is the first frame. The user should set up this breakpoint before starting the target application. The menu option is disabled while the host is connected to the target. Frame counting begins as soon as target application starts running; it does NOT wait until the PerfHUD connection is established. To disable the breakpoint, set the desired frame number to zero.
When enabled, the mode switches to Frame Debugger when the frames-per-second is less than or equal to the given value. Set the FPS value to zero to disable the breakpoint.
Force clear is used to enable a forced frame clear for color/stencil/depth buffers, before capturing inside the Frame Debugger. In many cases, the game developer will ensure every pixel is updated for each frame. This doesn't clear the frame to improve performance; instead, it focuses the current frame and omits the previous frame legend.
If any user shaders have been created in the Shader Viewer, this setting forces them all to be used in place of the original shaders.
This option brings up the Frame Delimiters dialog and allows the user to define which API call will be used to define the end of a "frame."
This dialog is used to let user configure what generic driver time counters are counted. We have 4 generic driver time counters. The concept of generic driver time counter is similar to a slot. You can configure the slot to let it collect APIs you are interested in to count the final value. For example, you want to know how many time spent on all
glUseProgram API, you can modify the generic counter 0~3 to include only one API
glUseProgram. And the counter will be shown in the time graph.
In the frame profiler, we can define several graphs to display hardware counters from target side. You can configure the graph via this dialog. (See Appendix C: EGL Perfmon Counters for explanations of the counters.)
Change the width of tabs in Shader Viewer.
Show line numbers in Shader Viewer.
Add or re-order the search path list used to look up high-level source.
Loads a debugging database from a PHF file and jumps to Frame Debugger.
A profile frame PHP file can be loaded after a debug frame PHF file and vice versa. Then the profiler and debugger frame can be switched to each other to help analysis the result. The PHF and PHP files are supposed to be captured at the same frame or very similar frame.
Save all current debugging information to a PHF file. A saved debugger frame is useful for diagnosing a problem while being disconnected from the target device.
Loads a profiling database from a PHP file and jumps to Frame Profiler.
Save all current profiling information to a PHP file. A saved profiler frame is useful for diagnosing a problem while being disconnected from the target device.

Use this to open the user manual in your system default PDF viewer. F1 for shortcut.
Use this to see the version number of PerfHUD ES. A button is provided to copy this information to the clipboard, in case the user needs to pass this on for support.
