AMD has begun to allow Linux driver help for its next-generation graphics processors primarily based on the RDNA 3 structure. As AMD’s next-gen Radeon RX 7000-series graphics playing cards are anticipated to be launched within the fall, the corporate is probably going beginning to check its new GPUs with companions, starting to allow Linux driver help, and doing different prep work..
Formally, the new sequence of Linux patches (found by @Kepler_L2) permits driver help for a few of AMD’s SoC21 and spinoff GPUs IP blocks (e.g., PCIe bus, interrupt handler, system administration unit I/O, and PCI BAR). The exact same patches formally allow help of AMD’s GFX11 structure, which is believed to be RDNA 3 (as GFX10 stands for RDNA2). For now, AMD’s GFX11 household formally has 4 members — three discrete graphics processors and one built-in — although we might count on extra GPUs to make use of the brand new structure ultimately.
It’s potential that SoC21 is AMD’s next-generation top-of-the-range codenamed Navi 31 GPU that helps all of the options of RDNA 3 together with probably the most superior reminiscence controller, show interfaces and different options.
One noteworthy tidbit about AMD’s Navi 30-series graphics processors enablement in Linux is the truth that AMD now not provides help of a selected chip by releasing a big patch (so to not share secrets and techniques with its rivals and market observers), however somewhat provides help for particular person IP blocks of its GPUs by making particular person IP-related patches accessible, notes Phoronix. This strategy additionally makes it simpler for AMD to clear its authorized/technical evaluation procedures.
GPUs primarily based on the identical structure are inclined to share constructing blocks, so enabling help of particular person IP blocks basically permits driver help of a number of graphics processors directly. In the meantime, since one GPU might have a block that one other GPU doesn’t have (e.g., one GPU comes with an HDMI 2.1 48G help, whereas one other continues to function HDMI 18G albeit with some HDMI 2.1 options), a block-by-block enablement doesn’t reveal which of the chips has which block.
