Subject: ACPI: Create proc entry 'power' only C2 or C3 is supported From: Yi Yang <yi.y.yang@xxxxxxxxx> ACPI processor idle driver makes sense only if the processor supports C2 or C3. For legacy C0 and C1, just the original pm_idle is working , statistics info about promotion, demotion, latency, usage and duration are empty or 0, so these are misleading, users'll think their CPUs support C states (C2 or C3), /proc/acpi/processor/CPU*/power shouldn't exist for this case at all.
.. On the other hand, this change might send many of us scrambling to try and figure out which kernel CONFIG option is responsible for the expected /proc/acpi/processor/CPU*/power entries not showing up. Thus just adding to the confusion by as much as it saves. What do others think? - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
