Tracing ACPI BIOS Code

You can use Advanced Configuration and Power Interface (ACPI) tracing to troubleshoot low-level platform issues. Follow the steps below to receive ACPI trace messages.

Important:

Run all commands in the Intel(R) Debug Extensions for WinDbg* command prompt.

  1. Connect to your target.

  2. Set a post-reset breakpoint by running the following command:

    forensic.setinitbreakpoint()
    
  3. Reset your target:

    itp.resettarget()
    
  4. Remove the reset breakpoint:

    forensic.removeinitbreakpoint()
    
  5. Enable ACPI trace messages:

    acpi.amlitrace()
    

The Intel(R) Debug Extensions for WinDbg* command prompt prints ACPI trace messages. To cancel tracing, press Ctrl + C.
