Linux support from AMD seems to be improving, as it has been on Windows. We'll be combining two separate, tiny stories into one, so bear with us. The first is from Fudzilla, and it states that AMD has AMDGPU-PRO 16.30 drivers for the RX 480 out on day one. It's nice to see that their Radeon driver initiative applies to Linux, too.
That brings us to the second story, this one from Phoronix. One Windows, the Crimson 16.7.1 drivers will include a fix for the RX 480 power issues (which we will obviously test of course). Michael Larabel was apparently talking with AMD's Linux team, and it seems likely that this update will roll into the Linux driver as well. They "are still investigating", of course, but it is apparently on their radar.
