Date: Sat, 15 Aug 2015 23:25:43 -0400 From: Len Brown <lenb@...nel.org> To: linux-pm@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Len Brown <len.brown@...el.com> Subject: [PATCH 2/7] tools/power turbostat: cpu0 is no longer hard-coded, so update output From: Len Brown <len.brown@...el.com> The --debug option reads a number of per-package MSRs. Previously we explicitly read them on cpu0, but recently turbostat changed to read them on the current "base_cpu". Update the print-out to reflect base_cpu, rather than the hard-coded cpu0.
