Installation

Firmware

WiFi and BLuetooth

The Linux firmware package is needed for wifi adapter to work.

It can be obtained by installing the Linux firmware package: sys-firmware/linux-firmware. For more info see iwlwifi.


Microcode

Intel released microcode updates that fixes fault on processors. Install the officially published microcode package sys-firmware/intel-microcode. For more info see Intel microcode.


Kernel

Recommended kernel config for sys-linux/gentoo-sources. More info at Kernel.

Note
This config is last tested on Linux Kernel sys-linux/gentoo-sources 5.4.60


Kernel config being maintained at au624tx_defconfig

Configuration

Compiler settings

More info is available at:

FILE /etc/portage/make.conf
# O2 for super-safe output
CFLAGS="-march=native -O2 -pipe"
CXXFLAGS="${CFLAGS}"
# Dual-core with enabled Hyper-Threading technology - 4 logical processors
MAKEOPTS="-j4"
# AMD64 architecture
CHOST="x86_64-pc-linux-gnu"


Packages settings

For more info: CPU_FLAGS_X86

FILE /etc/portage/make.conf
# Obtained via cpuinfo2cpuflags-x86
CPU_FLAGS_X86="aes avx2 mmx popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3 mmxext avx"
USE flags

With Intel Modesetting DDX as video driver and libinput as input driver add the USE flags glamor and libinput.

FILE /etc/portage/make.conf
# Intel kabylake
VIDEO_CARDS="intel i965"
VIDEO_CARDS="nouveau" ## only if you are going to configure dedicated gpu 
# Input devices
INPUT_DEVICES="libinput"
# Useflags
USE="libinput"

Utils and Extras

Enabling Mute LED light

Create the following file:-

FILE /etc/modprobe.d/snd-hda-intel.conf
## Enabling Mute LED for Hp Pavillion Notebooks Containing Realtek ALC295 Audio Card
options snd-hda-intel model=alc295-hp-x360
Optimize system

Use app-laptop/laptop-mode-tools, For more info check Power_management
