Ah yes, I've overseen this one.
What is the advantage of:
/sys/module/acpi/parameters/aml_debug_output
over:
/sys/module/acpi/parameters/{debug_level,debug_layer}
?
The first is also available even if CONFIG_ACPI_DEBUG
is not defined at all?
Yep, this is rather useful. I still would move the param into:
drivers/acpi/sysfs.c
if I touch this now anyway, where all the other
/sys tunables are flying around:
grep \/sys drivers/acpi/sysfs.c
* /sys/modules/acpi/parameters/debug_layer
* /sys/modules/acpi/parameters/debug_level
* /sys/modules/acpi/parameters/trace_method_name
* /sys/modules/acpi/parameters/trace_state
* /sys/modules/acpi/parameters/trace_debug_layer
* /sys/modules/acpi/parameters/trace_debug_level
/* /sys/module/acpi/parameters/acpica_version */
* /sys/firmware/acpi/tables/
* /sys/firmware/acpi/tables/dynamic/
* /sys/firmware/acpi/interrupts/
...if that's fine with you.
