The documentation below is *still valid*, if you actually want to use ich9utils.
|
||||||
|
You can find it in older Libreboot releases, up to Libreboot 20230625. The only
|
||||||
|
modification that ich9gen permitted was to change the MAC address, and ifdtool
|
||||||
|
can set read-only mode via `--unlock` argument on a ROM, so ich9utils was a
|
||||||
|
moving (read: not moving) part that basically did the same thing as providing
|
||||||
|
static images.
|
||||||
|
|
||||||
|
The initial plan was to rewrite ich9utils in a cleaner coding style, like that
|
||||||
|
used in nvmutil, but then it was decided instead that ich9utils would be
|
||||||
|
scrapped.

High Pitched Whining Noise on Idle in Debian or Devuan
|
|
||||||
======================================================================
|
|
||||||
|
|
||||||
Start powertop automatically at boot time.
|
|
||||||
|
|
||||||
Included with libreboot is a script called 'powertop.debian'. Run this
|
|
||||||
as root and it will setup powertop to run with --auto-tune at boot
|
|
||||||
time. Load the file in your text editor to see how it does that.
|
|
||||||
|
|
||||||
sudo ./resources/scripts/misc/powertop.debian
|
|
||||||
|
|
||||||
Might want to run with --calibrate first
|
|
||||||
|
|
||||||
If powertop doesn't work, another way (reduces battery life slightly)
|
|
||||||
is to add *processor.max\_cstate=2* to the *linux* line in grub.cfg,
|
|
||||||
using [this guide](../linux/grub_cbfs.md).
