Linux gaming is a blip when you compare it to (a) the total gaming market, (b) the professional creative market and (c) the big data/deep learning market. All of which AMD is selling graphics cards into. And it's not like Linux is even some massive growth market that justifies some risky investment.
This is not true for the animation/CGI/effects industry where Linux not only looms large but is growing.
I'm also sceptical of Linux having a small share of big data/machine learning since this is adjacent to servers where Linux dominates- would you mind sharing your sources? Nvidia's CUDA is cross-platform, this sets a baseline for whatever response AMD is planning.
the sooner fglrx dies, the better off the planet will be.
Today's 3rd spot on Top500 is occupied by a GPU-based supercomputer.
...which is equipped with NVidia cards.
And... I am not sure AMD has resources to design good GPUs either, the GPU I own, the 380X, is hot, power-hungry and buggy.
The RX480 launched recently to replace it, draws too much power from PCI-E slot and can damage people motherboards and raiser cards/cables.
So I am not entirely sure they have resources for their hardware division either, in fact the recent card launches from them all looked "rushed" in some way, and undertested. Some bugs are haunting their cards for 3 years now, and they don't even bother in putting in the "known issues" list anymore, because they have no idea how to fix it, despite having a 300-page+ thread on their support forums about it with people contributing lots of information.
I loved that line from his post, in particular. "We have the resources to design a billion-transistor GPU, but not to write a Linux driver for it."
Poor management on AMD's part does not constitute an emergency on the Linux kernel's part.
