------- Comment #73 from andreas.herrma...@amd.com 2009-03-03 04:21 ------- FYI, the 600MHz value for Pstate2 is from an ACPI table (containing _PSS (Performance Supported States) objects). For each Pstate it contains also the frequency, but the family 11h BKDG says about this value "CoreFreq (MHz) = The CPU COF specified by MSRC001_00[6B:64][CpuFid] rounded to the nearest 100 Mhz." This is a rounded value and explains the observed difference. I think, the powernow-k8 driver should determine the frequency from the Pstate MSR directly and not from this ACPI table. (BTW, the tool x86info determines the frequencies directly from the Pstate MSRs.) -- 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
