Ubuntu® Supported OS Kernel/Distribution

This repository contains the following drivers.

  1. Intel® Graphics Driver Backports(i915) - The main graphics driver (includes a compatible DRM subsystem and dmabuf if necessary)
  2. Intel® Converged Security Engine(CSE) - Converged Security Engine
  3. Intel® Platform Monitoring Technology(PMT/VSEC) - Intel® Platform Telemetry

Our current backport supports the following OS Distribution.

OS Distribution OS Version Kernel Version
Ubuntu® 24.04 Desktop 6.8 generic
24.04 Server 6.8 generic
22.04 Desktop 6.5 generic
22.04 Server 5.15 generic

Prerequisite

We have dependencies on the following packages

  • dkms
  • make
  • debhelper
  • devscripts
  • build-essential
  • flex
  • bison
  • mawk
$ sudo apt install dkms make debhelper devscripts build-essential flex bison mawk

For DKMS modules, we need to install dkms package too.

$ sudo apt install dkms

Dependencies

These drivers have a dependency on Intel® GPU firmware and a few more kernel mode drivers may be needed based on specific use cases, platforms, and distributions. The source code of additional drivers should be available at Intel GPU

Each project is tagged consistently, so when pulling these repos, pull the same tag.

Package creation

Dynamic Kernel Module Support(DKMS)

Creating i915 DKMS packages

$ make <Build Options> <DKMS Package Target>

Example:
	$ make i915dkmsdeb-pkg

	Generated package name :
		intel-i915-dkms_1.23.6.24.230425.29+i1-1_all.deb

Above command will create Debian package in parent folder. intel-i915-dkms_<release version>.<kernel-version>.deb

DKMS Kernel Headers Requirement

The kernel header used at the time of backporting may not be compatible with the latest version at the time of installation which can lead to installation issues. Please refer Version file to check value of UBUNTU_24.04_DESKTOP_KERNEL_VERSION/UBUNTU_24.04_SERVER_KERNEL_VERSION/UBUNTU_22.04_DESKTOP_KERNEL_VERSION/UBUNTU_22.04_SERVER_KERNEL_VERSION for Ubuntu®. It will point to the kernel version which is being used during backporting.

Please note that DKMS installation will skip if the kernel headers are not installed.

Ubuntu® 24.04 Desktop:

$ sudo apt install linux-headers-<UBUNTU_24.04_DESKTOP_KERNEL_VERSION> \
linux-image-unsigned-<UBUNTU_24.04_DESKTOP_KERNEL_VERSION>

Example:
       $ sudo apt install linux-headers-6.8.0-11-generic \
       linux-image-unsigned-6.8.0-11-generic

Binary Package

Creation of binary Debian can be done using the below command. By default it will use the header of the booted kernel, However it can be pointed to other headers via optional KLIB and KLIB_BUILD arguments.

$ make KLIB=<Header Path> KLIB_BUILD=<Header Path>/build i915bindeb-pkg

Example:
	$ make KLIB=/lib/modules/$(uname -r) KLIB_BUILD=/lib/modules/$(uname -r)/build i915bindeb-pkg

	Generated Files:
		intel-i915-<version>.$(uname -r)-1.x86_64.deb

Above command will create Debian package in parent folder.

Build Options

Build options provides a list of different arguments which can be passed during package creation or build.

Please refer to README_common for the full list of Build options.

Installation and verification

$ sudo dpkg -i intel-i915*.deb

Reboot the device after installation of all packages.

$ sudo reboot

Please refer to README_common for Installation verification process.

For verification, Please grep backport from dmesg after reboot. You should see something like below

$ sudo dmesg |grep -i backport
[    5.963854] COMPAT BACKPORTED INIT
[    5.968761] Loading modules backported from I915-23.6.24
[    5.976154] Backport generated by backports.git I915_23.6.24_PSB_230425.29
[    6.069699] [drm] I915 BACKPORTED INIT

Please refer to README_backport_version for different verification processes.

Uninstallation

$ sudo dpkg -r intel-i915*

Reboot the device after uninstallation of all packages.

$ sudo reboot
