Linux for Apple Silicon macs
We said external displays would come to Asahi Linux in 2025… and it’s still 2025! Here’s experimental kernel code for single-port DP alt-mode, for developers to test as we iron out the kinks before releasing to end-users: https://github.com/AsahiLinux/linux/tree/fairydust
For more information, make sure to watch Sven Peter’s talk at 39C3: https://media.ccc.de/v/39c3-asahi-linux-porting-linux-to-apple-silicon
Happy new year and happy hacking!
For those who missed my #Asahilinux #39c3 talk, it's available at https://media.ccc.de/v/39c3-asahi-linux-porting-linux-to-apple-silicon now.
I've also just pushed my slides to https://github.com/svenpeter42/39c3 and uploaded them as PDF to https://cfp.cccv.de/39c3/talk/YGHB9K/
3.5 hours until my talk about #asahilinux which will be recorded and also live streamed at https://streaming.media.ccc.de/39c3/one
In our final progress report for 2025, you'll find even more patches making their way upstream, 39C3, and a special treat for M2 Pro/Max MacBook users. Happy holidays from the Asahi Team!
Now that the Apple Silicon dwc3 driver is in -next it's time to continue with the Type-C PHY driver, which is the last part required for upstream USB3:

Another upstream kernel release, another progress report!

Thank you once again to everyone supporting us on OpenCollective and GitHub sponsors!
Just sent the next version of the Apple Silicon USB3 series, this time only the dwc3 changes: https://lore.kernel.org/asahi/20251013-b4-aplpe-dwc3-v1-0-12a78000c014@kernel.org/
After this, only the PHY itself is missing which I'll send next.
Since there’s been some confusion: this does *not* enable DisplayPort over these connectors or Thunderbolt. It only brings up the PHY correctly. For DisplayPort work on DCP is needed and for Thunderbolt the native host interface and finally the PCIe controller need to be brought up.
This series is just the first step required for both.
Just sent out v2 of the USB3 and Type-C PHY support
https://lore.kernel.org/all/20250906-atcphy-6-17-v2-0-52c348623ef6@kernel.org/
I've finally just submitted the RFC series for USB3 support on Apple Silicon machines. RFC because the entire Type-C machinery spans multiple subsystems and has quite a few quirks which makes the entire thing rather annoying to deal with and I'm not 100% convinced about the current approach.
This also includes some initial work for DisplayPort-altmode and USB4/Thunderbolt but both will require much more work after this is upstream, so don't get your hopes up just yet.

With Linux 6.16 now out in the wild, it’s time for yet another progress report! As we mentioned last time, the Asahi and Honeykrisp Mesa drivers have finally found their way upstream. This has resulted in a flurry of exciting GPU-related work. And now we've got merch!
As always, we want to thank everyone who support us as none of this would be possible without your generous support.
Want to show your love for Asahi Linux to the world? Now you can! Head over to https://www.hellotux.com/asahi to buy official Asahi Linux merch. A portion of each sale is donated to the project. Many thanks to @Hellotux for facilitating this!
Linux 6.15 is right around the corner, which means it's time for another progress report! We have been pretty busy behind the scenes and we have some exciting developments to share with you all!
As always, we want to thank everyone who support us as none of this would be possible without your generous support.

Looks like M4 support for #asahilinux is going be rather painful. We’re still focusing on upstreaming M1/M2 support but other people have been trying to bring up m1n1 on M4 and it looks like a few things changed:
When configuring a macho boot object we now get dropped into an environment where Apple’s SPTM is running in GL2 and we are supposed to talk to it from EL2 with MMU already enabled to setup pagetables. This neither works for Linux nor for running XNU under our hypervisor to reverse engineer the new hardware.
When configuring a raw boot object we’re dropped into EL2 with GL2 and most (all?) Apple specific extensions disabled. This is totally fine for Linux but we can’t run XNU under our hypervisor that we use to reverse engineer the hardware in this state. This also seems to be broken for >=15.2 right now because it probably isn’t very well tested 😕
We're pleased to announce that folks can now contribute financially to the project through GitHub Sponsors! 🎉
@gfxstrand We definitely appreciate your effort in doing so! Thanks~!
