AMD's Alex Deucher released a new version of the xf86-video-ati DDX driver for X.Org Servers on Wednesday night.

The new xf86-video-ati 7.5.0 is the driver that finally enables hardware acceleration for Hawaii assuming you have a new kernel and the updated microcode/firmware files. The AMD Hawaii acceleration does work but further work is needed particularly as the re-clocking support seems to get borked after a while, but that's work needed on the Radeon DRM kernel side and not by this DDX driver. For better perspective see AMD Radeon R9 290: Gallium3D vs. Catalyst Drivers.

The xf86-video-ati 7.5.0 driver also has new CIK/SI PCI IDs and other code improvements. Overall it's mostly a routine update while the enabling by default of Hawaii acceleration is the most prominent change. With the move to Wayland and the X.Org Server becoming less interesting, most of the noteworthy open-source Radeon Linux changes happen within the AMD Gallium3D drivers (R300/R600/RadeonSI) or the Radeon DRM kernel driver.

The full list of xf86-video-ati 7.5.0 changes can be found via the mailing list announcement.
