A new proposal for Linux graphics drivers is under discussion to introduce a user-space API for Variable Refresh Rate (VRR) handling. Phoronix reported today that this development aims to allow applications and users to specify target frame rates when VRR is active. This user-space API (uAPI) would enable finer control over display refresh rates. The new capability could be utilized for various purposes, such as limiting performance to manage power consumption or maintaining specific frame pacing below the display's native maximum refresh rate. As Phoronix noted, this proposal specifically involves "introducing a Linux user-space API to be able to specify frame rate targets for Variable Refresh Rate (VRR) handling on the Linux desktop."
