| |
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? -- MST
