During the windows merging period of Linux 5.19, David Airlie sent an update to the direct rendering Manager (DRM) subsystem this morning It is worth noting that the DRM display / graphics driver update adds support for Intel arc graphics dg2/alchemist and provides initial support for Raptor lake. In AMD, it has made preparations for the next generation of cDNA insight products and rdna3 radeon RX 7000 Series graphics cards.
Since Intel and AMD have completed all the enabling work for their latest graphics products, this DRM pull is another big problem. The pull changed 1302 files, added 495793 lines of code, and deleted 32019 lines of code. Due to the automatically generated header files and other header files related to providing new IP blocks for rdna3, most of the new lines are on the AMD graphics driver side. It is this pull that now the AMD graphics driver has more than 4million lines of code in the Linux kernel.
Intel graphics driver adds PCI IDs of multiple "motherboard down" DG2 desktop GPUs, provides initial support for Raptor Lake P and Raptor Lake s, and exposes the computing engine ABI and other DG2 functions for DG2. The Arctic sound m platform has added information, DisplayPort HDR support for Haswell and later, small PCI bar enablement, and various other changes.
In AMD radeon graphics, various new IP blocks are enabled, such as SMU 13 x. Soc21, etc. More work still needs to be done, but preparations for the next generation of cDNA and rdna3 graphics cards, which are expected to be launched later this year, are under way. As part of their new open source driver enablement approach, this enablement will occur block by block.
