Hi, all, This patch series is for T-state coordination. Patch 01 Set the bit of ACPI_PDC_SMP_T_SWCOORD. Patch 02 Check the parameter when calling the function of acpi_processor_get/set_throttling. Patch 03 Update the T-state coordination after obtaining _TSD info Patch 04 Add the t-state event notifier function Patch 05 Update the t-state for every affected cpu when t-state is changed I've tested this patch set on t61 laptop. It can work on the three T-state control mode(MSR, SystemIO, FADT).
