From 4653cc92ed509b8f9b340b16920e8cb683c85f40 Mon Sep 17 00:00:00 2001 From: Brian Inglis Date: Tue, 25 Feb 2020 16:44:16 -0700 Subject: [PATCH] cpuinfo:power management: add proc_feedback, acc_power linux 4.6 x86/cpu: Add advanced power management bits Bit 11 of CPUID 8000_0007 edx is processor feedback interface. Bit 12 of CPUID 8000_0007 edx is accumulated power. Print proper names in /proc/cpuinfo [missed enabling this 2016 change during previous major cpuinfo update as no power related changes were made to the Linux files since then] --- winsup/cygwin/fhandler_proc.cc | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/winsup/cygwin/fhandler_proc.cc b/winsup/cygwin/fhandler_proc.cc index 030ade68a..605a8443f 100644 --- a/winsup/cygwin/fhandler_proc.cc +++ b/winsup/cygwin/fhandler_proc.cc @@ -1397,8 +1397,8 @@ format_proc_cpuinfo (void *, char *&destbuf) /* ftcprint (features1, 8, "invariant_tsc"); */ /* TSC invariant */ ftcprint (features1, 9, "cpb"); /* core performance boost */ ftcprint (features1, 10, "eff_freq_ro"); /* ro eff freq interface */ -/* ftcprint (features1, 11, "proc_feedback"); */ /* proc feedback if */ -/* ftcprint (features1, 12, "acc_power"); */ /* core power reporting */ + ftcprint (features1, 11, "proc_feedback");/* proc feedback if */ + ftcprint (features1, 12, "acc_power"); /* core power reporting */ /* ftcprint (features1, 13, "connstby"); */ /* connected standby */ /* ftcprint (features1, 14, "rapl"); */ /* running average power limit */ }
