ACPI ALS : no traces in syslog

Development OS
1

I tried to activate the TRACE in acpi_als driver, but i can’t see anything in syslog.
Is there something i can do to see its traces ? I don’t have ALS on the laptop, i just need the init traces from the driver.

I’m looking at the driver sourcecode, and it doesn’t log anything in acpi_als_support. This is the first method that will be called to see if there is any hardware that the driver can use.

So, the initialization will stop there, and the driver will be unloaded. The traces in other parts of the code will not be seen because the code is never called.

You could try to add some traces in that function to see if they are viisble? (as far as I can see, traces are already enabled by default in this driver).
