/sys/module/acpi/parameters/:
trace_method_name
The AML method name that the user wants to trace
trace_debug_layer
The temporary debug_layer used when tracing the method.
Using 0xffffffff by default if it is 0.
trace_debug_level
The temporary debug_level used when tracing the method.
Using 0x00ffffff by default if it is 0.
trace_state
The status of the tracing feature.
"enabled" means this feature is enabled
and the AML method is traced every time it's executed.
"1" means this feature is enabled and the AML method
will only be traced during the next execution.
"disabled" means this feature is disabled.
Users can enable/disable this debug tracing feature by
"echo string > /sys/module/acpi/parameters/trace_state".
"string" should be one of "enable", "disable" and "1".
