Date: Thu, 21 Sep 2006 17:48:00 -0700 Message-Id: <11588860842488-git-send-email-dmitriyz@google.com> X-Mailer: git-send-email 1.4.2 Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org This patch-set factors out the thermal throttle processing code from i386 and x86_64 into a separate file (therm_throt.c). This allows consistent reporting of CPU thermal throttle events. Furthermore, a counter is added to /sys that keeps track of the number of thermal events, such that the user knows how bad the thermal problem might be (since the logging to syslog and mcelog is rate limited). Tested on 32bit and 64bit Intel P4 Xeons. Differences from last cut: - No more #ifdef CONFIG_X86_64.. sorry Andi :). x86_64 specific code is in arch/x86_64/kernel/mce.c - Commented the need/use for time_before64/time_after64. (I addressed Andi Kleen's concern about these macros in a followup from last attempt, but never got a response.) - More comments in therm_throt.c and individual patch descriptions arch/i386/kernel/cpu/mcheck/Makefile | 2 arch/i386/kernel/cpu/mcheck/p4.c | 26 +--- arch/i386/kernel/cpu/mcheck/therm_throt.c | 171 ++++++++++++++++++++++++++++++ arch/x86_64/kernel/Makefile | 4 arch/x86_64/kernel/mce.c | 27 ++++ arch/x86_64/kernel/mce_intel.c | 30 +---- include/asm-i386/therm_throt.h | 9 + include/asm-x86_64/mce.h | 4 include/asm-x86_64/therm_throt.h | 1 include/linux/jiffies.h | 15 ++ 10 files changed, 248 insertions(+), 41 deletions(-)
