According to Michael Larabel of Phoronix, FreeSync support (or VESA Adaptive-Sync / HDMI VRR) is going to be merged with the upcoming Linux 4.21 kernel cycle. This will enable full FreeSync support for Linux gamers who own an AMD GPU! Mr Larabel also found new AMD Zen linux-firmware, and a workaround for the AMD Radeon RX 590 under Linux. Assuming no major last minute issues, the code should then be merged into the Linux 4.21 mainline kernel when its merge window opens at the very end of December or early January. Linux 4.21 should then be released in March for those that may be planning a new monitor purchase or upgrade to one of these capable displays.
