Intel® Graphics Driver Backports for Linux® OS (intel-gpu-i915-backports)

This branch provides i915 driver source code backported for SUSE® Linux® Enterprise Server to enable intel discrete GPUs support.

We are using backport project to generate out of tree i915 kernel module source codes.

This repo is a code snapshot of particular version of backports and does not contain individual git change history.

Branches

suse/main will point to the currently supported version of SUSE® Linux® Enterprise Server.

We will add a new branch suse/sles<x.y> whenever a version is deprecated or moved to the maintenance phase.

NOTE: For sles 15sp4, please use backport/main branch.

Supported Version/kernel

our current backport is based on SUSE® Linux® Enterprise Server 15SP3. We are using the header of the latest available kernel at the time of backporting. However, it may not be compatible with the latest version at the installation time. Please refer Version file to check the BASE_KERNEL_NAME. It will point to the kernel version which is being used during backporting.

In case of an issue with the latest kernel, please install the kernel version pointed by BASE_KERNEL_NAME.

sudo zypper ref -s && sudo zypper install -y kernel-default-<BASE_KERNEL_VERSION> \
kernel-syms-<BASE_KERNEL_VERSION>

example:
    sudo zypper ref -s && sudo zypper install -y kernel-default-5.3.18-150300.59.49.1 \
    kernel-syms-5.3.18-150300.59.49.1

Product Releases:

Please refer Releases

Prerequisite

we have dependencies on the following packages

  • dkms (only for dkms build)

  • make

  • linux-glibc-devel

  • lsb-release

  • rpm-build

    sudo zypper install dkms make linux-glibc-devel lsb-release rpm-build

Dependencies

This driver is part of a collection of kernel-mode drivers that enable support for Intel graphics. The backports collection within https://github.com/intel-gpu includes:

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

Package Creation

Backports support two different kinds of packaging.

  1. Dynamic Kernel Module Support(DKMS) Packages
  2. Binary Packages

DKMS package creation

DKMS package consists of source required to build and install ko files agains kernel dynamically. We need to create dmabuf and i915 dkms packages using the below command.

    make dkmsrpm-pkg

Above will create rpm packages at $HOME/rpmbuild/RPMS/x86_64/

DKMS Installation

    sudo rpm -ivh intel-dmabuf-dkms*.rpm intel-i915-dkms*.rpm
    # Reboot the device after installation of all packages.
    sudo reboot

Binary Packages Creation

Binary rpm's consists of pre-built ko modules for particular kernel version and flavor. To create binary packages, Build system should be having SLES kernel and respective headers installed

Command to build single binary rpm (combination of dma-buf,drm and i915)

  make binrpm-pkg

Generated Files: intel-i915-kmp-default--1.x86_64.rpm

Command to build dma-buf binary rpm

If you want to generate seperate rpm, please use below command alternatively to binrpm-pkg.

  make dmabinrpm-pkg

Generated Files: intel-dmabuf-kmp-default--1.x86_64.rpm intel-dmabuf-symvers-default-.x86_64.rpm

Command to build i915 binary rpm

  make i915binrpm-pkg

Generated Files: intel-i915-kmp-default-.x86_64.rpm

Note: In case of seperate rpm creation, i915 will have dependency on dma-buf and uses dmabuf-symvers package symbol file. Installation should be done at once.

Binary package Installation

use below command to install binary rpm

 rpm -ivh <rpm>

Installation varification

Please grep backport from dmesg after reboot. you should see something like below

    > sudo dmesg |grep -i backport
