Well.. i got a turion on my laptop myself, and the powermanagement does
not work. The fan sounds like a jet engine, and it does not go down. The CPU is
unable to go idle and stuff, which makes it unable to go down in tempratur,
from when the PC is booted it will continue to slowly
The patch is certainly not safe to apply generally in my opinion.
Reading around the subject it appears that C1E should be supported in
parallel with tickless, if its not enabling by default you should be
able get it working usng the kernel command line parameter hpet=force.
If those of you who
The patch is harmless, it only adds accounting for time in C1E, so that you can
see in powertop, that your system is actually idle for e.g. 95% of the time. It
does nothing besides that. C1E is supported just fine in a vanilla kernel, it
has nothing to do with tickless (except that you cannot

I had to rework the patch to make it work on the kernel tree, but where did you
get this patch? I can't find it on the Linux kernel mailing-list, or even that
*anybody* knows about this outside launchpad?!
It would be nice if a Kernel developer looked at this first and agreed
with
Thanks for your responses. Sadly I don't know how to apply such a
patch. I have not tried the new kernel, as I need a free weekend.
If you are saying a battery life improvement is to occur from this
patch, won't dynticks need to work? I still have 250 wakeups in
powertop.

AMD turion does
Newer laptops with AMD Turion X2 and AMD Athlon X2 mobile processors (which are
C1E capable) are overheating and have very degraded battery life due to bugs in
/usr/src/linux/drivers/acpi/processor_idle.c (not properly implemented C1
support).
C1E replaces C2 and C3 states, so BIOS usually doesn't
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:
The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the
upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would
appreciate it if you could please test this newer 2.6.27 Ubuntu kernel.
There are one of two ways you should be able to test:
1) If you are comfortable
Hello!
I have the same problem on my HP 9533eg with a AMD Turion tl-60. It is
indifferent how idle the Laptop runs - it doesn't switch into any Powerstate.
uname -r says this: 2.6.24-18-generic
and this is the output from
cat /proc/acpi/processor/CPU0/*
processor id:0
acpi id:
