Superior Micro Gadgets (AMD) has simply posted a brand new patch sequence for Linux. That is anticipated in preparation for RDNA 4, the next-generation graphics structure.

For now, these patches don’t inform us a lot. Merely put, AMD’s Linux crew is performing enablement work for an unannounced new graphics structure. We don’t know when precisely RDNA 4 goes to come back out, so maintain your horses. Nonetheless, that is fairly thrilling as a result of the newest Steam Deck 2 rumors counsel it could use AMD’s RDNA 4 because the graphics structure!

Furthermore, I’m tremendous pumped for the highest-end RDNA 4 desktop graphics card, which can ultimately compete towards Nvidia’s subsequent behemoth, anticipated to be the RTX 5090. As per Phoronix, AMD’s Linux crew has posted the brand new patches to allow “up to date IP (mental property) blocks” for the GPU driver by AMD made for the Linux kernel.

It was earlier reported by Phoronix again in 2023 that the chipmaker has additionally posted ‘preliminary patches‘ for GFX12, a reference to the upcoming graphics structure (which is extremely anticipated to be RDNA 4). By the way in which, in Linux, “GFX10” refers to RDNA 3 graphics structure. Till the chipmaker makes an official announcement on RDNA 4, issues like this are going to maintain teasing us all.

Reportedly, these new patches are for enabling LSDMA 7.0, IH 7.0, HDP 7.0, and ATHUB 4.1. These are all parts in preparation for GFX12 (which is, once more, RDNA 4 if predictions are proper). These IP blocks have drastically increased model numbers. This additional factors us in direction of the brand new parts being meant for RDNA 4. This will probably be Workforce Pink’s subsequent main graphics structure overhaul!

ATHUB 4.1 is required for clock-gating / energy administration options, LSDMA 7.0 is the newest IP for Mild SDMA for basic objective System DMA (SDMA) on the GPU, IH 7.0 for the Interrupt Handler on the GPU, and HDP 7.0 for the Host Information Path assist for CPU accessing the GPU system reminiscence through the PCI BAR. – Michael Larabel, Phoronix

Mid 2024 is the anticipated merge window for Linux 6.9. For now, we don’t know if that is when AMD could have launched or developed any new graphics product (whether or not it’s for laptops, desktops, or anything) constructed with the newest next-gen RDNA 4 graphics structure.

What are your ideas on preliminary RDNA 4 enablement via Linux patches? When do you assume AMD will launch the brand new era graphics structure? Tell us within the feedback beneath.
