------- Comment #76 from andreas.herrma...@amd.com 2009-03-03 06:11 ------- Well, the HW is not overclocked or something like that under Linux. The frequency/voltage settings for each Pstate are obtained from the corresponding Pstate register when the Pstate is changed. It is just that powernow-k8 reports wrong frequencies whenever a frequency is rounded to 100 MHz, e.g. 550 MHz => ACPI reports 600 MHz and thus Linux thinks CPU clock is 600 MHz instead of 550MHz), Furthermore this involves that the corresponding frequencies in /sys/devices/system/cpu/cpu0/cpufreq and the "cpu MHz" in /proc/cpuinfo are incorrect. Not sure what this means for time keeping if clocksource is TSC and Pstate0 frequency were affected (say reporting 2100 Mhz instead of 2050 MHz). In any case, I think we should fix this for sake of correct frequency reporting. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
