Linux 5.19 gets nearly half a million lines of new graphics driver code
Linux 5.19 gets nearly half a million lines of new graphics driver code.
David Airlie has sent an update to the Direct Rendering Manager (DRM) subsystem for the Linux 5.19 merged window.
The DRM graphics driver update for Linux 5.19 includes full driver support for the latest graphics cards from AMD and Intel, so the amount of code is a bit unexpected: the changes consist of 1302 files, 495,793 new lines of code, and 32,019 deleted lines of code.
In terms of specific content, Intel’s driver work mainly focuses on support optimization and initial Raptor Lake enablement for Arc Graphics DG2/Alchemist .
Such as adding PCI IDs to various DG2 notebook GPUs, initial Raptor Lake P/S support, and more.
AMD is preparing for the next generation of CDNA Instinct products and RDNA3 Radeon RX 7000 series graphics cards.
For example, various new IP blocks are enabled, such as SMU 13.x, SOC21, etc.
Some other work includes Qualcomm MSM DRM driver adding eDP support, AArch64 support for QXL driver, Allwinner D1 support in Sun4i driver, DisplayPort support in ASpeed AST driver, MediaTek MT8186 support, Rockchip VOP2 support, and comparison of Small driver changes.
A large DRM pull request for Linux 5.19 was posted on LKML , and Linus Torvalds has pulled the DRM code and responded:
