Subject: [PATCH 2/4] tools/power turbostat: IVB Xeon: fix --debug regression
Date: Sat, 26 Sep 2015 01:05:13 -0400 [thread overview]
Message-ID: <756357b8e4b072fd5ee86421f794e071a348802b.1443243089.git.len.brown@intel.com> (raw)

From: Len Brown <len.brown@intel.com>
Staring in Linux-4.3-rc1,
commit 6fb3143b561c ("tools/power turbostat: dump CONFIG_TDP")
touches MSR 0x648, which is not supported on IVB-Xeon.
This results in "turbostat --debug" exiting on those systems:
turbostat: /dev/cpu/2/msr offset 0x648 read failed: Input/output error
Remove IVB-Xeon from the list of machines supporting with that MSR.
