It looks like AMD is preparing to introduce some new APUs/SoCs still relying on RDNA1-based graphics with open-source GPU driver patches posted this week extending the " [1]Cyan Skillfish " support to some new APU devices.

A patch series was posted this week adding five additional PCI device IDs to the Cyan Skillfish family within the AMDGPU Linux kernel driver. Cyan Skillfish support was originally brought up for Linux in 2021 for Navi 1x based APUs. Now four years later there are new products being prepped relying on the aging graphics capabilities... Certainly not as exciting as the [2]RDNA 3.5 graphics of today with the likes of the super exciting [3]Strix Halo . This also comes at a time when AMD Linux graphics driver engineers are already preparing a [4]GFX1250 "RDNA 4.5" for next-gen APUs .

The five new PCI device IDs for Cyan Skillfish graphics are 0x13DB, 0x13F9, 0x13FA, 0x13FB, and 0x13FC. The patches confirm these are for APU-based devices .

See [5]this patch series for those interested in the new code around Cyan Skillfish.
