ACPI can be used to provide CPU P-state throttling, but in the case of Intel CPUs, I think SpeedStep is probably a better/easier way to go. Most OSes support it, as long as they can identify the CPU. On FreeBSD, the eist driver already sees that the CPUs support SpeedStep, but doesn't attach due to not having the CPU in its configuration table. -nick > Matt -- n...@desert.net - all messages cryptographically signed signature.asc Description: OpenPGP digital signature ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech

ACPI is on my long list of things to do, I'll better move it up, the basic ACPI stuff needed is not that complicated. The ACPI Power is really complicated, but I have no plan to support that, as active power management is not something you want or need on a always on platform Best Regards, Soren Kristensen CEO & Chief Engineer Soekris Engineering, Inc. ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech

From what I have seen, mptable and atpic support are both designated as legacy capabilities on FreeBSD. The FreeBSD developers may not want to re-enable them in GENERIC. Support for non-ACPI configurations could become increasingly tenuous. With luck, the required options will remain available for some time to come, but it seems like an ACPI BIOS would be a very positive development for the longevity of the Net6501 with modern operating systems. -nick > Cheers, > > Denis, for...@acm.org > > PS.

Based on your input and what I had found earlier, I made a couple of FreeBSD 9.0-RC3 kernels to play with the options, and I found that "device mptable" is needed for the FreeBSD/amd64 kernel to boot on the net6501. Anyway, it's good to know that we'll be able to build and use 64-bit kernels... but I doubt we can get "device mptable" enabled in GENERIC at this late stage of the 9.0 release cycle (we are at RC3).

I was able to boot FreeBSD/amd64 9.0-RC3 just now. The key was to enable mptable and atpic support in the kernel. device atpic # Optional legacy pic support device mptable# Optional MPSPEC mptable support I also removed "device acpi", but that may not have been necessary. -nick > Cheers, > > Denis F. > ___ > Soekris-tech mailing list > Soekris-tech@lists.soekris.com > http://lists.soekris.com/mailman/listinfo/soekris-tech -- n...@desert.net - all messages cryptographically signed signature.asc Description: OpenPGP digital signature ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
