Summary: Enable C-state even when only C1 is present
Kernel Version: 2.6.11-rc
Status: NEW
Severity: normal
Owner: venkatesh.pallipadi at intel.com
Submitter: venkatesh.pallipadi at intel.com
Currently, /proc/acpi/processor/CPU*/power will not show C-state statistics
when only C1 is supported. The patch will enable the /proc/ Cstate interfaces
even when only C1 is supported. This should not add any performance overhead
due to acpi_idle routine, as we don't have anything to do at the time of
running idle routine.
Further, as Dominik pointed out, there can be a case where only C1 is enabled
in AC power and other C-states get enabled when on battery. The patch here
will help that case as well.
