Working code is better anyway (and in this case, it's first). Go to your favorite kernel.org mirror and check out /pub/linux/utils/cpu/crusoe/longrun-0.9.tar.gz It does everything you could ever want and more, as long as you include the CPUID and MSR devices in your kernel, set up the devices correctly, etc. Dan - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Re: setting cpu speed on crusoe
Hi Daniel, We're going through our docs and we have internal programs that we'll release for this so that you'll not just have docs but actually working code too. It just needs to be cleaned up a bit, and go through the proper channels (ever wonder why open source gets deveoped faster?). It really should be "any day now". Working code is better anyway (and in this case, it's first). Go to your favorite kernel.org mirror and check out /pub/linux/utils/cpu/crusoe/longrun-0.9.tar.gz It does everything you could ever want and more, as long as you include the CPUID and MSR devices in your kernel, set up the devices correctly, etc. Very cool. :-) Will we also be able to do a software upgrade of the cpu code morphing software in the future?

We are, but the documentation we mean for internal use sometimes tends to be in the "not good enough to be released" category. Anyway, the register the above is touching has nothing to do with "longrun", but with "coolrun" - it's the temperature control, not the CPU speed control. Now, obviously, CPU speed and temperature do have tons of things in common, which is why it gives somewhat expected results. We're going through our docs and we have internal programs that we'll release for this so that you'll not just have docs but actually working code too.

Re: setting cpu speed on crusoe
Hi! Junichi Morita and I have worked out how to access the crusoe "longrun" settings on the crusoe based VAIO. This allows you to enable power saving mode and slow the cpu down. It should help battery life a lot. There is no documentation? I thought transmeta is linux-friendly company ;-). Pavel the following will enable power saving and set the cpu to the slowest speed: setpci -s 0:0.0 a8.b=11 and this will restore you to max speed: setpci -s 0:0.0 a8.b=0e the bits are: LRON bit0: long run "on" - I'm not really sure what this does Did you try just asking linus?
