Some of the HSA-specific features implemented in the hardware need to be supported by the [[operating system kernel]] and specific device drivers. For example, support for AMD [[Radeon]] and [[AMD FirePro]] graphics cards, and [[AMD Accelerated Processing Unit|APUs]] based on [[Graphics Core Next]] (GCN), was merged into version 3.19 of the [[Linux kernel mainline]], released on February 8, February 2015.<ref name="kernelnewbies-3.19">{{cite web
