--- Comment #14 from Len Brown <l...@kernel.org> 2010-01-19 10:17:29 --- Created an attachment (id=24629) --> (http://bugzilla.kernel.org/attachment.cgi?id=24629) cpustat utility source code please compile this cpustat utility, run as root for 10 seconds or so, interrupt, and paste the output to this report. cpustat will print out the maximum turbo capabilities of your Nehalem, and will also print the idle time and the observed processor frequency at 2 second intervals. eg. when run on my desktop it shows that a single threaded program can cause the 2.93 GHz CPU to run a core up to 3.16 GHz for a 2 second interval, and if I run two cycle soakers, they both run at 3.06 GHz: # ./cpustat Nehalem multiplier 22, TSC frequency 2933 MHz Nehalem 4 cores active: 23 mult, max turbo frequency = 3067 MHz Nehalem 3 cores active: 23 mult, max turbo frequency = 3067 MHz Nehalem 2 cores active: 23 mult, max turbo frequency = 3067 MHz Nehalem 1 core active: 24 mult, max turbo frequency = 3200 MHz CPU: 0 1 2 3 4 5 6 7 c0%: 0.04 0.37 0.06 2.18 50.22 0.75 0.05 0.01 c1%: 50.50 2.44 0.16 4.59 0.32 2.06 0.17 6.76 c3%: 34.10 76.97 42.27 93.18 34.10 76.98 42.27 93.17 c6%: 15.37 20.22 57.51 0.05 15.36 20.22 57.51 0.05 GHz: 2.02 2.87 2.76 2.97 3.16 2.99 2.11 2.16 c0%: 0.02 0.62 0.13 4.01 99.73 1.41 0.02 0.00 c1%: 99.98 5.20 0.12 48.32 0.27 4.41 0.22 52.33 c3%: 0.00 94.17 99.75 47.63 0.00 94.17 99.75 47.64 c6%: 0.00 0.01 0.00 0.03 0.00 0.01 0.00 0.03 GHz: 3.06 3.06 3.06 3.06 3.12 3.06 3.06 3.06 c0%: 0.02 0.67 5.37 4.84 99.52 1.56 0.06 0.00 c1%: 99.98 5.40 0.15 5.38 0.48 4.50 5.47 10.22 c3%: 0.00 64.27 60.12 89.69 0.00 64.27 60.12 89.69 c6%: 0.00 29.66 34.35 0.09 0.00 29.67 34.35 0.09 GHz: 3.06 3.06 3.06 3.06 3.17 3.06 3.06 3.06 c0%: 0.02 0.64 100.00 5.62 100.00 1.55 0.03 0.01 c1%: 99.98 7.01 0.00 48.47 0.00 6.10 99.97 54.08 c3%: 0.00 61.15 0.00 45.82 0.00 61.15 0.00 45.82 c6%: 0.00 31.21 0.00 0.09 0.00 31.21 0.00 0.09 GHz: 3.06 3.06 3.06 3.06 3.06 3.06 3.06 3.06 c0%: 0.69 0.35 97.50 4.33 99.99 0.80 0.03 0.01 c1%: 99.31 3.77 0.08 3.92 0.01 3.32 97.56 8.24 c3%: 0.00 63.16 2.38 91.72 0.00 63.17 2.38 91.72 c6%: 0.00 32.72 0.03 0.03 0.00 32.71 0.03 0.03 GHz: 3.06 3.06 3.06 3.06 3.06 3.06 3.06 3.06 c0%: 1.00 0.04 0.07 0.83 75.32 0.05 0.03 0.01 c1%: 74.59 0.17 0.08 51.00 0.26 0.16 0.12 51.82 c3%: 24.38 71.13 94.71 48.11 24.38 71.12 94.71 48.12 c6%: 0.04 28.66 5.14 0.06 0.04 28.67 5.14 0.06 GHz: 2.98 2.26 3.04 2.91 3.10 2.74 2.01 2.66 c0%: 0.04 0.01 0.06 0.09 0.01 0.02 0.04 0.01 c1%: 0.07 0.03 0.07 0.05 0.09 0.02 0.09 0.13 c3%: 49.92 99.88 39.90 99.85 49.92 99.87 39.90 99.84 c6%: 49.97 0.08 59.97 0.02 49.98 0.09 59.97 0.02 GHz: 1.60 1.60 1.60 1.60 1.60 1.60 1.60 1.60 ^C -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Throughout its 18-year history, RSA Conference consistently attracts the world's best and brightest in the field, creating opportunities for Conference attendees to learn about information security's most important issues through interactions with peers, luminaries and emerging and established companies. http://p.sf.net/sfu/rsaconf-dev2dev _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
