From: Len Brown Date: Sat, 22 Sep 2012 05:25:08 +0000 (-0400) Subject: tools/power turbostat: add [-d MSR#][-D MSR#] options to print counter deltas X-Git-Tag: next-20120924~82^2~1^2 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=918ac3e4f9fa74bd4788039118cbfe7e038cb661;p=karo-tx-linux.git tools/power turbostat: add [-d MSR#][-D MSR#] options to print counter deltas # turbostat -d 0x34 is useful for printing the number of SMI's within an interval on Nehalem and newer processors. where # turbostat -m 0x34 will simply print out the total SMI count since reset.
