!amli set Options 

Parameters

Options

Specifies one or more options to be set. Separate multiple options with spaces. Possible values include:

spewon

(Windows XP and later) Causes full debug output to be sent from the target computer. This option should be left on at all times for effective AML debugging. See the Comments section for details.

spewoff

(Windows XP and later) Suppresses debug output.

verboseon

Turns on verbose mode. This causes the AMLI Debugger to display the names of AML methods as they are evaluated.

verboseoff

Turns off verbose mode.

traceon

Activates ACPI tracing. This produces much more output than the verboseon option. This option is very useful for tracking SMI-related hard hangs.

traceoff

Deactivates ACPI tracing.

nesttraceon

Activates nest tracing. This option is only effective if the traceon option is also selected.

nesttraceoff

Deactivates nest tracing.

lbrkon

Breaks into the AMLI Debugger when DDB loading is completed.

lbrkoff

Deactivates the lbrkon option.

errbrkon

Breaks into the AMLI Debugger whenever the interpreter has a problem evaluating AML code.

errbrkoff

Deactivates the errbrkon option.

logon

Enables event logging.

logoff

Disables event logging.

logmuton

Enables mutex event logging.

logmutoff

Disables mutex event logging.

DLL

Comments

If no options are specified, the current status of all options is displayed.

In Windows NT and Windows 2000, full debug output is always sent to the debugger. However, Windows XP and later versions of Windows usually filter out most of these messages. If you are running the AMLI Debugger on these systems, you need to turn this output on with !amli set spewon. Otherwise, numerous important AMLI Debugger messages will be lost.

If the AML interpreter breaks into the AMLI Debugger, this output will be automatically turned on.

For more details on this output filtering, see DbgPrintEx and KdPrintEx in the Windows Driver Kit (WDK) documentation.
