Valve haven't been sitting on their hands, as they have pushed out a fresh update for SteamOS that's currently in Beta. It's been a while and it's a good one.

They have rebased it against Kernel 4.11 and they have also updated the graphics drivers. The big thing here is that Valve have officially dropped AMDGPU-PRO in favour of Mesa. This goes to show how far Mesa has come, for Valve to be using it directly.

It also pulls in changes from the Debian 8.8 release, so it comes with everything there including the usual security updates too.

From the release notes:
QuoteIt has been a long time since the last update. We have not been idle. This update is huge. First, we have rebased our kernel changes on top of the latest 4.11 Linux kernel. We have updated all the graphics drivers. This update also switches SteamOS from the proprietary AMDGPU-PRO driver to the open source mesa driver. Our friends at Debian have released Debian 8.8[www.debian.org] so we picked up those updates as well. And of course it wouldn't be an update without the usual security patching.

Please be on the lookout for any regressions around game controller support, WiFi, or graphics.

This is easily the biggest SteamOS update we have ever done. Sorry it took so long but we hope this will give us a good base for quite a while.


Now they have this big update done and in Beta, I am keen to see what they do with SteamOS.

Awesome news <3
I sense an AMD APU based Steam Machine in a not so distant future
Cybolic May 22, 2017
Great news! Now would be a good time to release a new official Steam Machine with a decent GPU, maybe based on the NFC S4 Mini? :D
Pecisk May 22, 2017
It seems Valve does move towards AMD based Steam Machines for next generation. It is certainly can be at least interesting, if not more. It certainly will cut down pricing of potential SMs.

And yes, AMD and Mesa devs have done incredible job. It is certainly coming back to compete with Nvidia.
Nyamiou May 22, 2017
I hope they could release an AMD based Steam Machine but they also have to redo their marketing else they will have a backlash from corrupt gaming journalists (ArsTechnica and Polygon) again and they won't be able to do anything.

I wonder what happened to that portable Steam Machine that was going to be AMD based. That would be phenomenal.

The SMACH Zero... everything says it was supposed to be released Q4 of 2016... would love one myself.

IMO AMD should have just adopted Mesa as their official driver like Intel have. We don't need the graphics driver equivalent to MIR vs Wayland vs X.

The have, AMDGPU-PRO is just that, for the PRO cards like firegl. It is not meant to be used for gaming, that is what AMDGPU is for. This is according to bridgman @ phoronix, who is an AMD opensource driver dev.
Smellymangames May 23, 2017
This is really big news. Dedication to opensource is paying off for AMD. I excitedly await the Vega cards. Could be huge for AMD and future Steam Machines.

This sound great. If a AMD APU based Steam Machine is released, I gonna pick it up. All of my desktops and laptops are Nvidia.
With the rate radeonsi has been moving I'm expecting it to be completely on par with linux Nvidia proprietary in about a years time. And then be up to the same quality standards as Windows drivers a year after that. :crosses fingers:

I don't think it will even be a full year. Recent benchmarks of MESA 17.2 dev branch are putting most titles within 10 - 15% and this appears to be related to CPU overheads that I expect will be ironed out within a month or two. More important for me is that they get great Vega support and Freesync working this year.

btw we have to thank Ferral, Valve and all the devs competing to make the FOSS driver the best possible ^_^ There seems to be a real enthusiasm towards it. Perhaps Valve really is going to make a AMD SteamOS machine in a year or so ?

While they're at it, they could update the copy ofthe std c++ lib
in their runtime. Starting with the bootstrapper That is given
me headaches.

Awesome, but they need to fix the HDMI audio issues (DAL) and the issues with the Steam runtime.
Comandante Ñoñardo May 23, 2017
I wonder if someday We gonna have a final SteamOS release, so porters and developers of steam-only games will do their job focused on that final SteamOS release and not generic Linux distros...

If Valve really want to set a true ecosystem around them, and not be only a DRM, they need to set an standard in operative system and Hardware...They have the operative system, SteamOS, but is not ready.... now the must have the hardware config.
"Ok Devs and porters! You must optimize your games for this specific Linux distro, this family of CPU's and that family of GPU's"..

Is a hard decision for the users, but convenient for Devs and porters.

Keep in mind that the new Windows distro, called Windows 10-S (I know, We think the same word with that "S")), represent the Valve's worst nightmare and a good reason for the Linux incursion five years ago; you can only run apps from the Windows store... I don't know if the Steam client itself will be on the windows store (I use Win7), but certainly all the Steam catalogue will not be on the Windows store... So A LOT of Steam games will not run.

I know, Windows S is intended for students, but students like to play videogames and most videogames are Steam only, so..
C'mon Valve! The SteamOS revolution is now or never!

At the end of the day, it seems to be true what they said:

I've got my Alienware X51 (4700 with GTX 1060 and 16GB RAM and 1TB SSD) connected to my UHD TV in the living room running SteamOS (beta) full time. Works like a charm though 4K support in many games is lacking. I'd be all in for an AMD based Steam Machine. Bring it on!

I like Ars Technica in general, but it does frustrate me that their attitude toward linux gaming is very negative. However, I really don't think it is "corrupt". Just some unconscious bias from two of their main writers.

I do agree that Valve has to make some real effort toward marketing, though. Their SteamOS engineering team might be solid, but the public corporate attitude is embarrassing.

It is not just ArsTechnica. Some of the other tech forums I check out have a strong bias against it and always have the same silly arguments of market share, poor performance, blah blah (I usually get this when bring up the merits of vulkan and how it will help with porting games to linux). Then I slap them with all the porters and have to explain how all that works. They always comment on it without keeping up to date with what all is going on with linux gaming. I ditched windows over a year ago completely and couldn't be happier.

I completely forgot SteamOS existed to be honest.
skinnyraf May 23, 2017
Everyone focuses on the AMD driver change, but Nvidia is quite bleeding edge too with 381.22.

I hope that the update will go smoothly when this release hits stable, considering it will be a bump from 2.98 to 2.115.

The gaming world is very fickle. Gamers are easily offended and extremely tribal (Sony vs MS, Console vs PC, Android vs iPhone, etc.). Some people will be negative toward Linux because it is just another "opponent" in their narrow world view. I have learned not to worry too much about such people.

However, Ars Technica should know better - they strive to be a cut above other tech media. As an example of tribalism, reading Mark Walton's articles about Ryzen are embarrassing since they headline single-threaded gaming performance. I have run Intel chips for a number of years, but it does no-one any service to review things unfairly.

For any review, an author can decide to focus on something that they don't like. If that becomes the central to the review, everything else gets clouded over (eg. Ron Amadeo and plastic phone backs). For linux gaming, framerate is the nitpick that derails every review. Yes, it is a factor, but not really as important as everyone makes it out to be.
