[ACPI] Reduce acpi-cpufreq switching latency by 50%
The acpi-cpufreq driver does a P-state get after a P-state set to verify whether set went through successfully. This test is kind of redundant as set goes throught most of the times, and the test is also expensive as a get of P-states can take a lot of time (same as a set operation) as it goes through SMM mode. Effectively, we are doubling the P-state latency due to this get opertion. momdule parameter "acpi_pstate_strict" restores orginal paranoia. http://bugzilla.kernel.org/show_bug.cgi?id=5129 Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
