Strange, on my system it does exist:

along with the cpu{0..3} options.
When going through the CPUFREQ options in menuconfig, the following option
mentions a boost entry:
**
CONFIG_X86_ACPI_CPUFREQ_CPB:
The powernow-k8 driver used to provide a sysfs knob called cpb
to disable the Core Performance Boosting feature of AMD CPUs. This
file has now been superseeded by the more generic boost entry.
By enabling this option the acpi_cpufreq driver provides the old
entry in addition to the new boost ones, for compatibility reasons.

It depends on the CPU frequency governor. If CONFIG_X86_INTEL_PSTATE is
set and active (depending on your CPU model), the traditional governors
(like ondemand) and their correspondig sysfs entries are disabled.
For example I have the former (cpufreq) entry on my old core2 laptop,
but no such entry on my machines with i5/i7 with pstate despite the same
3.12.x kernel everywhere.
Generally pstate is much better than ondemand for both performance and
especially powersave mode.
Also AFAIK cpufrequtils are unmaintained/deprecated/dead, you should
migrate to sys-power/cpupower. It's slightly different but IIRC easy
to switch to.

I don't have the directory even on systems with this kernel option
enabled, it must be something else.

[gentoo-user] More emerge oddity in chroot

Wiped the whole system and restored from backup (heavy overkill, but I wanted everything to be in the same, consistent state). 2. Run bad-blocks tests on all partitions (though all but / and /boot are in logical volumes - I don't know to what extent that will have affected the results). 3. Remerged portage. 4. Recompiled the kernel, 3.12.13. 5. Booted previous good kernel,3.10.32. 6. Emerged natively on the Atom box for which the chroot is a build host. At various stages I got bizarreness like the kernel panicking at boot on a previously good kernel config, before it even switched to the frame buffer; or, during shutdown, exiting from KVM or some such, even though I've never used KVM. Portage works fine outside the chroot and is at the same version, 2.2.8-r1. It has python3 set in package.use in both cases, so I also tried: 7. Removed python3 USE flag from sys-apps/portage. Is my hardware dying? Or maybe I am. Time to seek intelligent conversation down the pub. :-( -- Regards Peter

Re: [gentoo-user] problems with usb audio and midi
thanks for your answer! actually, i just realized that it's working now. unfortunately i don't know what of all the things i've been trying made the difference... $ cat /proc/asound/cards 0 [M2496 ]: ICE1712 - M Audio Audiophile 24/96 M Audio Audiophile 24/96 at 0xec00, irq 16 1 [CODEC ]: USB-Audio - USB Audio CODEC Burr-Brown from TI USB Audio CODEC at usb-:00:1a.1-2, full speed 2 [nanoKONTROL2 ]: USB-Audio - nanoKONTROL2 KORG INC. nanoKONTROL2 at usb-:00:1a.1-1, full speed the usb audio card is working. the midi controllers, on the other hand, although recognized by the system, are not seen by the midi sequencers i tried (rosegarden and qtractor). i'll have to investigate more, because it's the midi controllers what i'm interested in. It means USB-1.1 as defined by AMD (I think). lspci | grep OHCI should show if you need it. mmm... lspci | grep OHCI gives nothing, so i guess i'll disable these modules in the kernel. thanks again, and if anyone knows how i could actually use those midi controllers, i would appreciate any help. lj

I haven't tried this myself but I believe you need CPU_FREQ_DEFAULT_GOV_USERSPACE kernel config. And I guess this is the ultimate reference: https://www.kernel.org/doc/Documentation/cpu-freq/index.txt Well, for sure I have not kept up with all these issues. But some kernel versions ago, there was heavy work on the I/O and various schedulers, memory management etc etc. All of these settings effect the processor(s) speeds, idle etc. I started reading about overclocking my FX-8350 after I got the water cooler installed and realize about a year ago, many, many things have changed. So I guess what I'm saying is this subject get's very complicated very quick, with lots of new options for performance tuning on a system. I'd read up a bit and find similar things that folks have done to optimize a workstation (laptop) for speed or economy (power consumption) and start with that before tweaking and testing the myriad of things that can effect your system's overall performance. On laptops, some graphics hardware can be put to sleep for substantial power savings, along with tricks on HD operations.. Surely monitoring the cpu temerpatures is the best place to start, but there is so much more to tune now, kernel and otherwise. Arch Linux has some nice docs that may get your research going: https://wiki.archlinux.org/index.php/CPU_frequency_scaling https://wiki.archlinux.org/index.php/maximizing_performance hth, James
