This feature should increase the clock speed of one of my four CPU cores from 1.6 GHz to 2.8 GHz when all other cores are idle. Works fine with another well-known OS, but does not with openSUSE. One of perhaps several reasons is that the only available C-State is C1: alex@i7:~> cat /proc/acpi/processor/*/power active state: C0 max_cstate: C8 maximum allowed latency: 16000 usec states: C1: type[C1] promotion[--] demotion[--] latency[003] usage[00000000] duration[00000000000000000000] After I saw http://bugzilla.kernel.org/show_bug.cgi?id=15064, I tried Vanilla kernel 2.6.33-rc8, and it enables C2, but still no other C-States and no Turbo Boost. Reproducible: Always Steps to Reproduce: 1. Do something that uses one CPU core 100% 2. monitor CPU frequency 3. Actual Results: 7 virtual cores running on 933 MHz, 1 on 1600 MHz Expected Results: 7 virtual cores running on 933 MHz, 1 on 2800 MHz or at least nearby Notebook: ASUS PRO62J-JX033C (based on M60J) CPU: Intel Core i7-720QM -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
