I have the Ibex Beta (kernel 2.5.27-5 is the current kernel, I believe) running on my HP Pavilion dv6324us with the AMD Turion 64x2 processor. I also do not see any usage of c states beyond C1.
Output of cat /proc/acpi/processor/CPU0/* is as follows: processor id: 0 acpi id: 0 bus mastering control: yes power management: yes throttling control: no limit interface: no <not supported> active state: C0 max_cstate: C1 bus master activity: 00000000 maximum allowed latency: 2000000000 usec states: C1: type[C1] promotion[--] demotion[--] latency[000] usage[02414989] duration[00000000000000000000] C2: type[C2] promotion[--] demotion[--] latency[005] usage[00000000] duration[00000000000000000000] C3: type[C3] promotion[--] demotion[--] latency[020] usage[00000000] duration[00000000000000000000] <not supported> -- AMD turion does not have support for c states https://bugs.launchpad.net/bugs/188739 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
