AMD Linux Patches Add GDDR7 Driver Support

AMD has submitted Linux graphics-driver patches that add GDDR7 as a recognized video-memory type and introduce support for two newer hardware interface blocks, steps that prepare its software for upcoming graphics hardware but do not confirm a product or launch plan. The patches add the GDDR7 identifier to AMD’s open-source AMDGPU driver. They also include support for IH 8.0, an interrupt-handler block, and NBIF 7.10, a revision of the New Bus Interface. The changes build on earlier driver work involving Display Core Next 6 and GFX 13.0.x, which reports have associated with AMD’s next-generation graphics development. The work has drawn attention because AMD’s current Radeon RX 9000-series cards, based on its RDNA 4 architecture, use GDDR6. The new driver entry shows that the software can recognize GDDR7, but it does not establish that a particular AMD graphics card will ship with that memory. AMD has not announced specifications for RDNA 5, confirmed its memory configuration or provided a launch schedule. The driver updates are consistent with software preparation for future hardware.
