Linux 6.12 Lands QR Code for DRM Panic Messages, Intel LNL, BMG Graphics Enabled
Linux 6.12 enhances the Direct Rendering Manager with QR code error messages, supports Intel's Xe2 graphics, increases DRM device limits, and includes updates for AMD and other graphics drivers.
Read original article
Linux 6.12 has introduced significant updates to the Direct Rendering Manager (DRM) kernel graphics/display driver, including the ability to display QR codes for kernel error messages. This feature aims to simplify the process of capturing error information, replacing lengthy text messages that can be difficult to read on smaller displays. The QR code functionality is implemented using the Rust programming language. Additionally, the new version enables support for Intel's Xe2 Lunar Lake and Battlemage discrete graphics by default, ensuring that the Xe kernel driver is readily available for new Intel laptops. Intel has also increased the maximum number of DRM devices from 64 to accommodate multi-GPU servers and virtual devices. On the AMD side, enhancements include per-queue reset support, updates for RDNA4/GFX12, and improved support for newer Instinct GPUs. Other updates include support for various Adreno GPUs, AST2600 VGA support, and enhancements to the Matrox MGAG200 driver and Rockchip DW HDMI code. These changes reflect ongoing efforts to improve graphics support and performance in the Linux kernel.
- Linux 6.12 introduces QR code support for kernel error messages via the DRM Panic infrastructure.
- Default support for Intel's Xe2 Lunar Lake and Battlemage graphics is included.
- The maximum number of DRM devices has been increased from 64 to support multi-GPU configurations.
- AMD graphics updates include per-queue reset support and enhancements for newer GPUs.
- Various other driver updates improve support for different graphics hardware.
