AMD is continuously working on bringing new features to Linux 6.6 as it introduces FreeSync Panel Replay support & begins enablement of its next-gen RDNA 4 GPUs.
AMD Plans on Going All-Out Here On Linux, Offering Early Next-Gen RDNA 4 GPU Support & Bringing New Features
For those unaware of the feature, FreeSync Panel Replay is a new feature that works so that when the content on the screen is unchanged, the refresh rate is dropped automatically to reduce power consumption. The feature is similar to Apple's ProMotion display technology but is intended to be used in monitors and laptops. AMD released the initial patch of the feature on Linux a month ago, intending to reduce the workload on GPU when content is unchanged.
The FreeSync Panel Replay is expected to be an upgrade over traditional Panel Self Refresh (PSR). Apart from this, AMD has also released "new GPU support around SDMA 6.1 support, HDP 6.1 support, and SMUIO 14.0", which, as disclosed by Phoronix, is an early preparation for its next-gen GPU lineup based on the RDNA 4 graphics architecture. The lineup is not expected to launch until next year but the red team has stated that it will evolve the performance further over the existing RDNA 3 GPUs and we can also expect a slew of new features. Expect more information on RDNA 4 GPUs by the coming year as we get closer to launch.
AMD has been working to provide better support to Linux users. The company has been prepping for the Zen 5 CPU release, as it has released several patches in Linux 6.6. Moreover, AMD has also started to resolve the annoying "fTPM" issues on Linux, which has caused severe troubles for consumers. AMD looks to retain its share of Linux, which is why the company has been active in releasing new patches and fixes.
