Asahi Linux's progress report for Linux 6.19 covers several major milestones. DisplayPort Alt Mode via USB-C is now working in the experimental 'fairydust' branch after years of reverse engineering four hardware blocks (DCP, DPXBAR, ATCPHY, ACE), though it remains developer-only due to known quirks. M3 MacBook Air can now boot to a full Plasma desktop thanks to three new contributors, but a general release requires GPU driver work, DCP bring-up, and speaker safety support. 14"/16" MacBook Pros now support 120 Hz displays starting with kernel 6.18.4. The DCP driver is being refactored to support hardware planes, HDR experiments, Y'CbCr video, and a new 'Apple Interchange' compressed framebuffer format. Webcam support was fixed across multiple layers including Mesa, PipeWire, and the GPU kernel driver. GPU upstreaming has begun with IGT test patches, and OpenGL/Vulkan memory copy and clear performance saw major improvements. Fedora Asahi Remix is also gaining a DNF5-based PackageKit backend.
