下載pacman並編釋
pacman 在 Linux_Cross_Compiler_tools/Pacman/X86底下
git clone git@github.com:xxxxx/Linux_Cross_Compiler_tools.git


./pacman -Syy
完成編釋動作之後，並執行pacman資料庫更新，db檔會儲存在 /var/lib/pacman/sync 之下
./var/lib/pacman/sync/core.db
./var/lib/pacman/sync/extra.db
./var/lib/pacman/sync/community.db
./var/lib/pacman/sync/archlinuxfr.db

開始下載與安裝 geany

./pacman -S geany

 geany 的可執行壓縮檔會被下載到 ./var/cache/pacman/pkg/
./var/cache/pacman/pkg/geany-x86_64.pkg.tar.xz

[Linux Kernel] How to compile ASUS_WMI & ASUS_NB_WMI

I want Fn+F9 can work. So the follow step is procedure for my testing. It work.

---

make menuconfig

Device Drivers → X86 Platform Specific Device Drivers

Tick up

<M>   WMI  (will open - < >   ASUS WMI Driver)

Tick up

    <M>   ASUS WMI Driver (when tick up this time will tick up another item was called Asus Notebook WMI Driver)
        <M>     Asus Notebook WMI Driver

Check .config

[happy@localhost linux-4.6.2]$ grep -inr "asus_wmi"  .config
3177:CONFIG_ASUS_WMI=m
[happy@localhost linux-4.6.2]$ grep -inr "asus_nb_wmi"  .config
3178:CONFIG_ASUS_NB_WMI=m

---

How to find the method. I check my .config in my archlinux. The command like below.
zcat /proc/config.gz > .config

And I find my settings in my archlinux have two option have been opened.
CONFIG_ASUS_WMI=m
CONFIG_ASUS_NB_WMI=m

So I decide to download the linux kernel to find how to make those two option appear on my .config.

---

Why I want try this option, because my touchpad(Fn+F9) no work. I search other information that told me maybe I need this kernel module. So I want to compile it, and try if this module can let my touchpad work or not.

---

After set up the .config, then we need to start compile our kernel.
There have two method can do this job.

Method 1:
Use genkernel to compile kernel.

A: No specific .config
    genkernel all (Builds all stages — the initrd, kernel image and modules.)

B: Specific .config
    genkernel --config=/path/to/genkernel.conf all

Method 2:
Copy the bzImage to /boot
/usr/src/linux/arch/x86/boot/bzImage –> /boot

I need to find which one is initramfs

Edit /boot/loader/entries/gentoo.conf

title Gentoo Linux
initrd /initramfs-genkernel-x86_64-4.4.6-gentoo
linux /bzImage
options root=/dev/sda2 rw

Explain:
sda2 (/mnt/)
mkfs -t ext4 /dev/sda2

sda1 (/mnt/boot)
mkfs -t fat /dev/sda1

sda4 (/mnt/data)
mkfs -t ext4 /dev/sda4

mkswap /dev/sda3
swapon /dev/sda3

mount /dev/sda2 /mnt
