Controlling Profiling Using the Device Keyboard when Running the Profile-Enabled OS Image

  • Article

For a CEPC, the keyboard drivers implement various types of profiling control for the following device shortcut keys.

Windows CE .NET 4.1 and earlier

To Do this
Run object call profiling. Press the F8 shortcut key.
Run buffered Monte Carlo profiling. Press the F9 shortcut key.
Run kernel call profiling. Press the F10 shortcut key.
Run unbuffered Monte Carlo profiling. Press the F11 shortcut key.
Quit profiling. Press the F12 shortcut key.

Windows CE .NET 4.2

To Do this
Toggle between buffered, unbuffered, and CELog storage modes. Press the F8 shortcut key.
Run Monte Carlo profiling. Press the F9 shortcut key.
Run kernel call profiling. Press the F10 shortcut key.
Run object call profiling. Press the F11 shortcut key.
Quit profiling. Press the F12 shortcut key.

The following code example shows two sample outputs that were generated while running a profile-enabled kernel on a CEPC.
