In recent weeks there have been a lot of open-source AMD Radeon graphics driver patches flying around for the GFX12 graphics engine , Video Core Next 5 , and other new graphics intellectual property (IP) blocks that appear to be for next-generation "RDNA4" Radeon graphics. This week yet more patches have been posted publicly.

Notably, patches were posted for enabling PSP 14.0 as the next-generation Platform Security Processor (PSP). The Platform Security Processor block on GPUs handles firmware validation and other low-level security-related tasks. That PSP 14.0 block enablement includes PSP versions 14.0.2 and 14.0.3. The patches don't reveal if there is any notable end-user related changes with PSP 14.

Meanwhile sent out separately today was PSP 14.0.1 support . There were also patches this Valentine's Day for the SDMA 6.1.1 and NBIO 7.11.1 .

Again, presumably all these new IP versions are for different upcoming RDNA4 graphics processors but hard to ascertain particular product details given the AMD graphics block-by-block enablement strategy of more recent years. In any event, great seeing these patches continue to flow out publicly pre-launch so that by the time the graphics cards are shipping to customers there will hopefully be out-of-the-box Linux support with modern distributions.
