Build Instructions

These instructions generally avoid assuming much prior experience with building the kernel so if you know what you're doing feel free to diverge however suits you.

git clone https://github.com/rib/linux git checkout -b wip/rib/oa-next origin/wip/rib/oa-next

Configure the build to only build what's currently needed by your running machine, to minimize what needs to be built (TIP: plug in any USB devices you use frequently before doing this step, including a USB stick, so won't have to always reboot to your distro kernel for basic USB functionality):

make localmodconfig

(Say yes to any questions)

Give the kernel a version suffix to distinguish it from your distro kernel:

make menuconfig

Navigate as follows:

->General setup
'Local version - append to kernel release'

And set the Local version to "-drm-intel"

Make sure to uncheck 'Automatically append version information to the version string' if currently set.

Now build the kernel:

make

(Make a cup of tea)

Personally I then have a ./install.sh script for moving the kernel to /boot, generating an initrd and ensuring it will be listed by Grub. For major distros like Ubuntu and Fedora such a script can simply be:

#!/bin/sh sudo make modules_install sudo make install

If you use ArchLinux (I do) then you can use something like:

#!/bin/bash
set +x

VERSION=`cat include/config/kernel.release`

sudo make modules_install
sudo mkinitcpio -k $VERSION -g /boot/initramfs-drm-intel.img
sudo cp -v arch/x86/boot/bzImage /boot/vmlinuz-drm-intel
sudo cp System.map /boot/System.map-drm-intel

With the kernel built, then install it:

chmod +x ./install.sh
./install.sh

Later if fetching newer version of the driver it should typically only be necessary to run:

make
./install.sh
