Beginning yesterday and continuing today are several patch series beginning to lay the foundation in the AMDGPU kernel graphics driver for enabling some next-generation graphics IP. Due to the AMD graphics driver block by block enablement strategy and IP-based discovery adopted by their driver over the past few years, it’s not clear what this new hardware enablement is for whether it’s RDNA5 / UDNA or some RDNA4 refresh. In any event, the Linux driver enablement has begun.

Yesterday saw the PSP 15.0.8 IP posted. Not much is revealed by this updated Platform Security Processor (PSP) block and an incremental revision over what’s already supported by the AMDGPU driver. The Platform Security Processor block on AMD GPU hardware handles firmware validation and other low-level security-related tasks.
