Intel’s open-source Linux graphics driver engineers are making progress in enabling the Xe2-based system for Lunar Lake integrated graphics. They are now focusing on the Battlemage discrete GPUs, successors to the DG2/Alchemist hardware. With the upcoming Linux 6.11 kernel cycle, they have achieved a critical milestone of being able to control a connected display/monitor via a Battlemage GPU.
A significant batch of drm-intel-next patches has been released for Direct Rendering Manager driver changes targeting Linux 6.11. The most important update is the enablement of the Battlemage Xe2 HPD display. Intel Linux graphics driver engineers have been working on display support for Battlemage, and with the release of Linux 6.11, everything is expected to be in good shape. However, it is unclear how well Intel Xe2/Battlemage Linux support is overall and what other components are still missing. The feature is still hidden behind experimental options, indicating that more work is needed before it is ready for Linux enthusiasts and gamers. It is hoped that by the projected release day later this year, all the latest open-source code will be in good condition.
Changes to the Intel kernel graphics driver for Linux 6.11 are also introducing Panel Replay functionality, which aids in energy-saving measures. Additionally, the update provides support for advanced link power management without DP AUX and Link Between Frames (LOBF) support, as well as backup handling for link training failures in DisplayPort Multi-Stream Transport (DP MST) links. Other enhancements include Enabling Content Matching Refresh Rate (CMRR) for Lunar Lake.
The main batch of changes to the Intel kernel graphics driver in Linux 6.11 can be found in a pull request. The Linux 6.11 merge window is set to open in mid-July, with the stable kernel anticipated to be available in September. Linux 6.11 is expected to power Ubuntu 24.10 and other fall Linux distributions.
In summary, Intel’s open-source Linux graphics driver engineers are making strides in enabling the Xe2-based system for Lunar Lake integrated graphics and Battlemage discrete GPUs. The upcoming Linux 6.11 kernel cycle will bring significant enhancements, including the ability to control a connected display/monitor via a Battlemage GPU. Panel Replay functionality is being introduced for energy-saving purposes, along with various other improvements to the Intel kernel graphics driver. Linux 6.11 is set to power upcoming Linux distributions, such as Ubuntu 24.10.
