Edit: As of now (April 1 2017)
I won't be adding anything else to the thread. I kept up management as the driver originally developed however there isn't much more news to come out about how performance will increase or XYZABC things that may happen. IF YOU HAVE SOMETHING YOU WANT ADDED TO THE THREAD please message me and I will add it to the header post here towards the top. Any forwarding news to come out, as far as I can see, has to do with compatibility with hardware. Farther down the line there may be a major breakthrough, such as the windows driver being a massive shit or guides to make the driver better, but I won't be digging it up any more so don't expect updates on the header. If you check this specific post for your news, go to phoronix or linux IRC channels to see what is up, or, the latest posts at the bottom.
Thanks.
Edit:
With the new Ryzen chips out, I would appreciate some notes on the over all linux performance for future posts like this. If you have ryzen and an RX card or multiple RX cards then some notes of over all performance would be well appreciated.
Edit:
Tacking on to the edit that was added below, 4.10 is in release state right now. For the most part, additions to the driver should be relatively minor, but there is supposed to be some hooks that are fixed that don't connect one SOME systems. Example being like my old phenom 2 machine. The next update should have a lot of bugs with the GCN 1 cards patched out as well, so those with a 250X, 270X, 370, 275, and 375, as well as mobile 7770, M275X, and M370X, should see performance gains. Not magnanimous, but between 5% and 15%. This comes off of IRC dev talk on freenode.
4.9.0.0 is out now so all GPU's should have AMDGPU support now, thank fuck. If you have problems with it ask here or in the small linux problems thread. Thanks.
If you have recently been getting "Invalid ROM Contents" and associated messages....

Rather than having 800 threads pop up in the next few months and annoy everyone with the same 2 questions, I'm taking the initiative to have one single thread. Then all the info can be in one place and hopefully we don't have to dig into the VERY BROKEN SEARCH (gaben plz) to find one thread.
Anything AMDGPU? Please put it here.
If you are new to linux, as many here are, and do not know what AMDGPU is, or AMDGPU-PRO, it is a driver for AMD cards that is meant to replace FGLRX, also known as Catalyst Control Center (you can argue the latest FGLRX available is the crimson driver, I'm not convinced), and be a better driver in linux with native support / better support for OpenGL, CL, Vulkan, and other tools. As it stands, 290 / 390, 2/380/85/X, and the fury cards are garunteed to work. Though as it seems, it varies between cards no matter what (from what I have personally seen).
Edit
These are the CURRENT supported cards (kernel 4.7) for AMDGPU-PRO
EDIT:
GCN 1.0 is going to be added by kernel 4.9 according to a recent press release.
Here are some articles pertaining to AMDGPU and recent events:

EDIT:
Somehow I think videos might also help some people find some bugs or compare what they should be getting. Visual resources.
This is from may
If any new videos pop up from people like AdoredTV who talk about this stuff and they talk about linux drivers please message them to me.
There are some users here that use AMDGPU as their daily, but I personally have to use FGLRX as I have a 370. Please don't ask me questions as I will just be able to find articles for you ^^; It seems that at the moment anything higher than a 370 or 270X has support, weather variant (it can be rough). If you have a low low end card (HD series, 250X, 260X) expect spotty performance or just no support any time soon if ever. As a 370 is basically a refresh on the 270X both cards can expect support soon.
All other information on AMDGPU can be taken from this Archwiki page if you need to know how to install it, how it works, or current troubleshooting methods.
https://wiki.archlinux.org/index.php/AMDGPU
I use the archwiki for every distro. If you don't know how to swap info between distros yet, please ask here OR on IRC.

EDIT:
Here is a Linux Gaming News thread.
Again, this thread is here as many changes are to start coming soon, I believe, and progress will be made now as the RX 480 is out and other cards are starting to be announced / released.
And please for the love of GOD, I do not care, nor does anyone else, about how great you nvidipenis is. If fights like this happen, please start another thread or go to PM's. Derailing will not be acceptable here.
Edit: Also just thought of this: Anyone with info on Wine and how well games work VIA wine with AMDGPU please post here too! It would be very very helpful.
