Hi,
for WMI drivers the list platform-driver-x86@xxxxxxxxxxxxxxx should probably be
on CC too.
Also all other WMI drivers, even for hwmon stuff are located in
drivers/platform/x86 so it may be better to put it there, too.
Not really. If any of those other drivers are pure hwmon drivers, they
should reside in drivers/hwmon instead. And, yes, that really includes
the gigabyte-wmi driver. We don't have arbitrary drivers in drivers/pci
either just because they are drivers for pci devices.
Fair enough.
I suppose it would be too much churn to move gigabyte-wmi to
hwmon now though, correct?
Is it ? I don't recall the reason why it was added to drivers/platform/x86
in the first place. I see other single-use wmi drivers in that directory
as well (eg xiaomi-wmi, which should be in input). Is there some unwritten
rule stating that all wmi drivers shall reside in drivers/platform/x86,
no matter what subsystem they touch ?
Having the platform-driver-x86 on Cc would still be useful as they can provide
guidance about using the ACPI/WMI/platform APIs.
Sure, but that is unrelated to the driver location, and the opposite argument
can be made as well (that drivers implementing subsystem code should be reviewed
by subsystem maintainers). That is a much stronger argument in my opinion.
Guenter
For example by using the WMI bus as mentioned in my other mail would allow
to completely remove the manually maintained DMI list and instead directly bind
to the WMI GUID for any device that supports this GUID.
(This is possible as this WMI API seems to be self-describing, so all
specific parameters can be discovered by the driver)
