Pallipadi, Venkatesh d306ebc286 ACPI: Be in TS_POLLING state during mwait based C-state entry ... ACPI deep C-state entry had a long standing bug/missing feature, wherein we were sending resched IPIs when an idle CPU is in mwait based deep C-state. Only mwait based C1 was using the write to the monitored address to wake up mwait'ing CPU. This patch changes the code to retain TS_POLLING bit if we are entering an mwait based deep C-state. The patch has been verified to reduce the number of resched IPIs in general and also improves the performance/power on workloads with low system utilization (i.e., when mwait based deep C-states are being used). Fixes "netperf ~50% regression with 2.6.33-rc1, bisect to 1b9508f" http://marc.info/?l=linux-kernel&m=126441481427331&w=4 Reported-by: Lin Ming <ming.m.lin@intel.com> Tested-by: Alex Shi <alex.shi@intel.com> Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>		2010-02-22 13:10:14 -05:00
