AMD Updates DMCUB Firmware For RDNA3.5 Graphics With Strix Point
As I noted in yesterday's AMD Ryzen AI 9 HX 370 review and in particular the new RDNA3.5-based Radeon 890M graphics, I used updated DMCUB firmware with the open-source Linux graphics driver stack to workaround some screen freezes and kernel errors initially experience while using the Linux 6.10 kernel
That updated DMCUB firmware is now public within the upstream linux-firmware.git repository for those that may be picking up a new AMD Ryzen AI laptop with RDNA3.5 graphics in the coming days. For those picking up an AMD Ryzen AI 300 series laptop soon, you'll want to grab the latest firmware from linux-firmware.git so you will be in good shape for the integrated graphics support. The Git commit notes the DMCUB firmware changes as ABM [Adaptive Backlight Management] improvements, enable/disable FEC [Forward Error Correction] for all PHY, and block c-state while handling p-state.
