Subject: shpc with acpi=off?
Date: Thu, 16 Feb 2012 17:04:22 +0200 [thread overview]
Message-ID: <20120216150421.GA26167@redhat.com> (raw)
I have a box where shpc works fine with acpi,
as well as when acpi is not built into kernel,
but fails with acpi=off
Some debugging seems to indicate that
acpi_get_hp_hw_control_from_firmware
fails with acpi=off.
Is this a bug or is there a reason to prevent shpc
from working in this setup?
Do we even care about acpi=off?
Assuming we want to make acpi_get_hp_hw_control_from_firmware
succeed with acpi=off, what is the best way to do this?
Check acpi_pci_disabled?
Thoughts?
