Hi,
In Hardware Certification we have adopted FWTS for testing power
management (amongst other things), including S3, shutdown and reboot. At
the moment it is giving us a few issues because FWTS is quite strict
about how it checks for kernel warnings and other issues. For Hardware
Certification we need to be less strict, but without ignoring any
problems which might be worthy of preventing the systems from being
certified. The purpose of this email is to kick off a dialogue about
which errors we really need to pay attention to for certification.
Can you elaborate a little more about the features that are causing you
problems and which ones are useful? Maybe some examples too?
I'm working my way through all the failures we've seen, but just to get
the ball rolling, I offer this one as an example:
1. 00054 summary High failures: 1
2. 00055 summary klog test, at 1 log line: 15
3. 00056 summary "HIGH Kernel message: [ 1918.822903]
[Firmware Bug]: ACPI: No _BQC method, cannot determine initial
brightness"
Seen when running reboot tests. I assume the net effect of this bug
would be to reset the brightness upon every boot? Or would it break the
brightness control completely?
It depends on the machine, but probably it may be the underlying reason
why brightness controls are not working correctly. The kernel certainly
wasn't happy, it complained about it, so it needs investigating.
I'm not sure which version of fwts you are using, but it should produce
some advice like:
_BQC (Brightness Query Current level) seems to be missing. This method
returns the current brightness level of a built-in display output device.
