Hi,
I tried out the patch Bjorn sent some days ago to autoload ACPI modules
via udev. The attached patch is based on latest test tree and includes
Bjorn's code. This works, but is not nice.
I had to tweak pnp to:
- also register ACPI devices which have no _CRS func
- allow (one byte longer) ACPIXXXX _HIDs to be used as PNP ids.
Now I got the following modules autoloaded (without the need of any
userspace adjustments):
battery, asus_acpi, button, ac (tested)
fan, ibm_acpi, acpi_memhotplug, container, sbs,..
(should also work, but untested)
I also wanted to use the suspend/resume stuff from there to point to the
acpi_driver->suspend/resume funcs, but this does not work as
pnp_driver->suspend/resume is used there, no idea whether this could be
mapped somehow, I didn't see an easy way.
Another problem is that e.g. thermal_zones do not have a PNP id.
We could add a dummy _HID like ACPI9999 for that one?
Is it intended to pass all ACPI devices to pnpacpi in future?
Not sure whether this is such a good idea.
IMO it's better to let the stuff stay or be added to drivers/acpi.
There already is suspend/resume for acpi devices there now, the uevent
stuff should also go there?
Comments?
Thomas
