HN discussionMacs do allow both of those things. Valve is even borrowing some of the work done for the Mac version of Linux to add support for Proton on ARM hardware. > Gaming on Linux on M1 is here! We’re thrilled to release our Asahi game playing toolkit, which integrates our Vulkan 1.3 drivers with x86 emulation and Windows compatibility. https://rosenzweig.io/blog/aaa-gaming-on-m1.html

HN discussionI don't think it's feasible to separate technology from the people themselves. What we do, in some way or the other touches people, real people, people with feelings, dreams and aspirations. To ignore where such contributions to humanity come from, is to ignore a person's existence, their struggles and what makes them, well, them. I recently stumbled on [1], > I’m on the board overseeing Linux graphics. Half of us a…

HN discussionThere are definitely some features omitted from Apple's GPU, but fairly early in the reverse engineering process, Alyssa Rosenzweig provided several examples of hardware features present in Apple's GPU that are not exposed by Metal: https://rosenzweig.io/blog/asahi-gpu-part-4.html

HN discussionThe key words are "optimized" and "OpenGL 4.6 with Zink". "Functional" and "OpenGL 2.1" is a different story, and the same trustworthy source said in https://rosenzweig.io/blog/asahi-gpu-part-6.html that: > thanks to the tremendous shared code in Mesa, a basic OpenGL driver is doable by a single person. I’m optimistic that we’ll have native OpenGL 2.1 in Asahi Linux by the end of the year. It's likely that even a ba…

HN discussion"Please temper your expectations: even with hardware documentation, an optimized Vulkan driver stack (with enough features to layer OpenGL 4.6 with Zink) requires many years of full time work. At least for now, nobody is working on this driver full time3. Reverse-engineering slows the process considerably. We won’t be playing AAA games any time soon."

HN discussionThis is one of the first Linux kernel driver writen in rust! Also all of this has progressed so fast thanks to Alyssa doing bunch of GPU reverse engineering on macOS and writing coresponding userspace MESA driver. https://rosenzweig.io/blog/asahi-gpu-part-6.html

HN discussionAre these things so important that we should give up the easier maintainability (and potentially, security) that comes from centralization and the standardization of user clients? I absolutely think projects like Matrix are worthwhile, but it seems foolish to me to argue that there are no benefits that come from doing things the way Signal does. Besides, as sexy as decentralization is, in the wild it is not really p…
