Valve may very well produce one of the near future's most popular non-mobile, consumer, Linux distributions. SteamOS will be marketed for gaming PCs (some very compelling ones at that) starting next year. CES will definitely be interesting. With such a popular distribution, and as an existing member of the Khronos Group, it makes sense for Valve to join the Linux Foundation... and they just did.
It is still unknown to what extent Valve joined Linux (members are classified by level of contribution from Platinum to Silver) and we likely will not know until their list is updated. While they probably will not be hanging out with Intel and others in the platinum category, Silver is not the most noteworthy of statuses... alongside Barnes and Noble (likely because of the Nook) and Twitter.
Another addition is the HSA Foundation. AMD is already a Gold member (y'know... HSA's faja) and ARM is Silver so I cannot see HSA being much more than that. Still, Linux will be an important focus for the heterogeneous computing architectures to endorse: both in terms of back-end server optimization and customer-facing devices.
Of course I am not belittling any contribution. Still, there is that desire to see Valve lead the pack. Ultimately, though, it is not the size of the badge: it is how you wear it.

Today is a big day for AMD as they, along with four other major players in the world of processors and SoCs, announced the formation of the HSA Foundation. The HSA Foundation is a non-profit consortium created to define and promote an open approach to heterogeneous computing. The primary goal is to make it easier for software developers to write and program for the parallel power of GPUs. This encompasses both integrated and discrete of which the HSA (heterogeneous systems architecture) Foundation wants to enable users to take full advantage of all the processing resources available to them.
On stage at the AMD Fusion Developer Summit in Bellevue, WA, AMD announced the formation of the consortium in partnership with ARM, Imagination Technologies, MediaTek, and Texas Instruments; some of the biggest names in computing.
The companies will work together to drive a single architecture specification and simplify the programming model to help software developers take greater advantage of the capabilities found in modern central processing units (CPUs) and graphics processing units (GPUs), and unlock the performance and power efficiency of the parallel computing engines found in heterogeneous processors.
There are a lot of implications in this simple statement and there are many questions that are left open ended to which we hope to get answered this week while at AFDS. The idea of a "single architecture specification" set a lot of things in motion and makes us question the direction of both AMD and the traditionally ARM-based companies of the HSA Foundation will be moving in. AMD has had the APU, and the eventual complete fusion of the CPU and GPU, on its roadmap for quite a few years and has publicly stated that in 2014 they will have their first fully HSA-capable part. We are still assuming that this is an x86 + Radeon based part, but that may or may not be the long term goal; ideas of ARM-based AMD processors with Radeon graphics technology AND of Radeon based ARM-processors built by other companies still swirl amongst the show. There are even rumors of Frankenstein-like combinations of x86 and ARM based products for niche applications.
Looks like there is room for a few more founding partners...
Obviously ARM and others have their own graphics IP (ARM has Mali, Imagination Technology has Power VR) and those GPUs can be used for parallel processing in much the same way that we think of GPU processing on discrete GPUs and APUs today. ARM processor designers are well aware of the power and efficiency benefits of utilizing all of the available transistors and processing power correctly and the emphasis on an HSA-style system design makes a lot of sense moving forward.
My main question for the HSA Foundation is its goals: obviously they want to promote the simplistic approach for programmers, but what does that actually translate to on the hardware side? It is possible that both x86 and ARM-based ISAs can continue to exist with libraries and compilers built to correctly handle applications for each architecture, but that would seem to me to be against the goals of such a partnership of technology leaders.
In a meeting with AMD personnel, the most powerful and inspiring idea from the HSA Foundation is summed up with this:
"This is bigger than AMD. This is bigger than the PC ecosystem."
The end game is to make sure that all software developers can EASILY take advantage of both traditional and parallel processing cores without ever having to know what is going on under the hood. AMD and the other HSA Foundation members continue to tell us that this optimization can be completely ISA-agnostic – though the technical blockages for that to take place are severe.
AMD will benefit from the success of the HSA Foundation by finally getting more partners involved in promoting the idea of heterogeneous computing, and powerful ones at that. ARM is the biggest player in the low power processor market responsible for the Cortex and Mali architectures found in the vast majority of mobile processors. As those partners trumpet the same cause as AMD, more software will be developed to take advantage of parallel computing and AMD believes their GPU architecture gives them a definite performance advantage once that takes hold.
What I find most interesting is the unknown – how will this affect the roadmaps for all the hardware companies involved? Are we going to see the AMD APU roadmap shift to an ARM-IP system? Will we see companies like Texas Instruments fully integrate the OMAP and Power VR cores into a single memory space (or ARM with Cortex and Mali)? Will we eventually see NVIDIA jump onboard and lend their weight towards true heterogenous computing?
We have much more the learn about the HSA Foundation and its direction for the industry but we can easily say that this is probably the most important processor company collaboration announcement in many years – and it does so without the 800 pound gorilla that is Intel in attendance. By going after the ARM-based markets where Intel is already struggling to compete in, AMD can hope to create a foothold with technological and partnership advantages and return to a seat of prominence. This harkens back to the late 1990s when AMD famously put together the "virtual gorilla" with many partners to take on Intel.
