While the Asahi Linux project has faced some setbacks, such as most recently with Alyssa Rosenzweig leaving the project and still working to bring-up M3/M4 support, the upstreaming effort by Asahi Linux developers to get their changes to the upstream Linux kernel continues.

As another very unfortunate setback for the Asahi Linux project moving forward after Hector Martin left the project as did Asahi Lina pausing work on open-source Apple driver development, Alyssa Rosenzweig announced today that she is stepping away from the project following the successes in bringing up Apple M1 and M2 graphics drivers for Linux.

In addition to this week seeing Apple SoC DT updates prepped for Linux 6.18 and Apple laptop lid events and power button driver patches posted for review for the mainline Linux kernel, published today on the Linux kernel mailing list are the request for comments (RFC) on patches for enabling USB3 support with Apple Silicon M1 / M2 SoCs.

Following the recent Apple SMC driver upstreaming to handle rebooting Apple Silicon Macs under Linux, the latest code volleyed on the kernel mailing list for review is support for handling laptop lid events and power buttons. Plus Apple sensor monitoring driver support too.

While the Linux v6.17 merge window only wrapped up earlier this month, Apple Silicon DeviceTree "DT" updates have already begun queuing for the Linux 6.18 merge window that will happen in October.

The Apple System Management Controller (SMC) driver was successfully merged this week into Linux 6.17 for being able to reboot modern Apple M1 / M2 Macs under Linux (the Apple M3 / M4 Linux support remains in development). It's the latest improvement for Apple Silicon on the upstream Linux kernel compared to the downstream Asahi Linux code that has been carrying the SMC driver and other in-development/tentative patches.

While there have been various elements of the Apple M1 and M2 SoC support in the mainline Linux kernel along with support for various Macs, different features have been missing from the upstream kernel such as the Apple GPU kernel graphics driver as one big example. On a more fundamental level, the upcoming Linux 6.17 kernel is going to cross off another low-level expectation for Apple Silicon Macs on the mainline kernel: the ability to reboot the system.

Sven Peter today sent out all of the Apple SoC driver and DeviceTree (DT) updates aiming for the soon-to-happen Linux 6.17 merge window.

Over the past week a number of Apple device support additions have been queued up into the HID subsystem's "for-next" branch ahead of the Linux 6.17 kernel cycle.

While Linux 5.13 back in 2021 added support for the Apple Magic Mouse 2, only now with the Linux 6.16 kernel is there support arriving for the USB-C version of the Apple Magic Mouse 2 that debuted last year.

With the Linux 6.15 kernel soon to debut as stable, the Asahi Linux project issued a new blog post outlining some of the new code they managed to get upstream for this next mainline kernel version as well as some of their other efforts for enabling Linux on modern Apple Silicon hardware.

Sven Peter has mailed out the Device Tree "DT" updates for benefiting Apple Silicon hardware with the upcoming Linux 6.16 merge window.

The latest bit of hardware enablement coming out of Asahi Linux and queued for introduction in the mainline kernel the next cycle is PCI Express (PCIe) support for the Apple M2 Pro SoC.

Submitted today via DRM-Misc-Next for queuing in DRM-Next until the Linux 6.16 merge window in June is the Asahi driver user-space API "UAPI" header. This is the user-space API intended for the Asahi kernel graphics driver for supporting the Apple M-Series graphics hardware under Linux. But due to being written in the Rust programming language and various kernel abstractions not yet ready among other obstacles, only the user-space API header is set to be added and not yet introducing the actual Direct Rendering Manager driver.

As a sooner than expected follow-up to the recent news article around Apple M1 / M2 / M3 core support for the GCC compiler, that code has now been successfully merged in time for the upcoming GCC 15 stable compiler release.

When it comes to compiler support for Apple Silicon and their hardware at large, Apple has long been focused on the LLVM/Clang toolchain given their long history with it, employing many of the developers, and Xcode being based on LLVM. The GNU Compiler Collection (GCC) though may soon see upstream support for the newer Apple Cores thanks to the work of GCC developer Iain Sandoe along with the input of engineers from Arm and the Apple open-source team.

Sven Peter who remains one of the very active Asahi Linux developers and working on upstreaming various elements of Apple Silicon support for the Linux kernel has sent up warning flares around the eventual Apple M4 support.

Back during the Linux 6.13 kernel cycle initial support for many (pre-M1) Apple devices were upstreamed including various iPad, iPhone, and iPod Touch devices. That though was the very preliminary support and continuing to work their way upstream are various drivers/patches to further enhance the support. Now for the Linux 6.15 kernel is a new Apple backlight driver for controlling the backlight on various mobile Apple devices.

Following Hector Martin stepping down from the Asahi Linux project that he founded for bringing Linux to Apple Silicon hardware, Asahi Lina announced today that she is pausing work on all of the Apple GPU driver development she had been pursuing for Asahi Linux with the open-source DRM kernel driver as well as Mesa contributions.

In hopefully helping Asahi Linux reduce their downstream patch burden and helping to enhance the overall flow of new Apple Silicon related code into the mainline Linux kernel, another developer has agreed to serve as an official code reviewer over the ARM Apple bits within the Linux kernel.

Already queued ahead of the Linux 6.15 merge window opening later this month are DeviceTree support for Apple's T2 SoCs as well as other DeviceTree additions set to be mainlined. A third round of DeviceTree patches were sent out on Sunday morning to the Linux kernel mailing list for the upcoming v6.15 cycle.

The upcoming Linux 6.15 kernel is expected to merge two new Direct Rendering Manager (DRM) display drivers for supporting the Apple Touch Bar displays on older Intel x86 Macs and a newer "ADP" driver for handling the Apple Touch Bar displays on the newer Apple M1/M2-powered MacBooks.

Sven Peter continues work on upstreaming more of the Apple SoC support to the mainline Linux kernel. On the DeviceTree side following the DT support for Apple T2 SoCs sent out last month, another set of updates were submitted this week ahead of the Linux 6.15 merge window.

A set of patches were posted today for review by the upstream Linux kernel developers in providing driver support for the Apple web camera and image signal processing (ISP) for Apple M-Series devices. This is enough to get the web camera support working on recent MacBooks while this code is now undergoing review for hopefully being mainlined in the Linux kernel.

While there has been the recent drama over upstream maintainership over Apple Silicon / Asahi Linux code, Sven Peter is continuing to move things forward for the upstream kernel and this week sent out a set of Apple SoC DeviceTree updates intended for the upcoming Linux 6.15 kernel cycle.

For those making use of the Intel-powered Apple MacBook Pro laptops featuring the Touch Bar, better support for that interface is slated to land with the upcoming Linux 6.15 kernel cycle.

This week was the dramatic decision by Asahi Linux lead developer Hector Martin to step down as upstream kernel maintainer for the Apple Silicon (ARM) code following friction with other kernel developers over Rust affairs within the kernel. He still intends to contribute code to Asahi Linux's downstream kernel and Linus Torvalds has already merged the patch dropping him as an upstream maintainer. Now a new co-maintainer has volunteered to help oversee the Apple Silicon code for the mainline kernel.

Following arguments on the Linux kernel mailing list the past few days over some Linux kernel maintainers being against the notion of Rust code in the mainline Linux kernel and trying to avoid it and very passionate views over the Linux kernel development process, Asahi Linux lead developer Hector Martin has removed himself from being an upstream maintainer of the ARM Apple code.

Apple is the latest CPU vendor being affected by side-channel attacks. All Mac laptops since 2022, all Mac desktops since 2023, and all iPhones / iPad Pro / iPad Air / iPad Mini models since 2021 are affected by these new SLAP and FLOP attacks.

While Linux 6.13 is introducing basic support for various Apple iPads and iPhones using A-series SoCs, the support is just that: basic. Various feature limitations remain for those dreaming over the prospects of running Linux on older Apple mobile devices. One of various feature limitations remaining are around backlight control for different models and for that there is the Apple DWI backlight driver for Linux that continues to be hacked on.

While not as exciting as if it were Apple M3/M4 device support hitting the upstream mainline Linux kernel, but for those with some older Apple (pre-M1) devices around, support for a number of older SoCs and boards is set to arrive with the upcoming Linux 6.13 kernel.

A patch is pending for enabling support for the USB-C model of Apple's latest Magic Trackpad input device under Linux.

Alyssa Rosenzweig provided an update today at the XDC 2024 conference in Montreal on the open-source "Honeykrisp" Vulkan driver for Apple Silicon M1/M2 SoCs within Mesa and related work as part of the Asahi Linux project to provide for a nice Linux gaming experience atop the ARM-based Apple devices.

Device Tree patches have been posted to the Linux kernel mailing list for review and possible upstreaming to the mainline Linux kernel for booting Apple iPhones, iPads, and iPods that use the A7 to A11 SoCs.

A set of nine patches were posted for review on Tuesday in aiming to get the Apple Touch Bar working well under Linux for the x86 T2-based Macs.

The EFI changes have been merged for the in-development Linux 6.11 kernel. Notable this cycle on the EFI side is removing support for EFI fake memory maps and then a workaround to get dual GPU support working for some of the older x86-based Apple MacBook Pros by pretending that Apple macOS is booting rather than Linux.

For those using an Apple Magic Keyboard with a T2-secured Mac, the upcoming Linux 6.11 kernel will enable working keyboard backlight support.

While the Asahi AGX Gallium3D driver for OpenGL support with Apple Silicon on Linux has been maturing nicely and is quite capable these days, the Vulkan support hasn't been coming together as quick or for as long. But a new Apple Silicon Vulkan driver was recently started by Asahi Linux / Mesa developers and is looking positive for being able to become a compliant Vulkan 1.3 driver for the Apple M1 on Linux.

While rolling out the new iPad Pro tablets today, Apple announced the M4 as their newest in-house silicon design.

The Asahi Linux project working on the AGX Gallium3D driver for Mesa has now managed to achieve OpenGL 4.6 conformance as well as OpenGL ES 3.2. This is a big upgrade for the Linux OpenGL support on the Apple M1 as previously only OpenGL 4.1 was exposed.

Following last month's release of Fedora Asahi Remix 39 for the Asahi Linux project's new flagship distribution for running on Apple Silicon hardware, a lengthy blog post was posted this weekend outlining some of the ongoing development efforts for Apple Silicon on Linux and newly-enabled Fedora Asahi capabilities.

Apple tonight announced the M3, M3 Pro, and M3 Max as what they are promoting as the "most advanced chips" for a personal computer and leverage the TSMC 3nm process.

The AGX Gallium3D driver developed by the Asahi Linux crew for providing reverse-engineered OpenGL / GLES support on Apple Silicon M1/M2 hardware is now formally compliant with OpenGL ES 3.1.

An independent developer has posted an open-source Linux driver for review in order to handle the Apple Studio Display backlight control under Linux. The Apple Studio Display uses a Thunderbolt (DP) interface for display but lacks any hardware controls. Thus a USB interface is used by the monitor for controlling attributes like the display backlight brightness.

Experimental driver code available via the Asahi Linux "edge" packages allow for OpenGL 3.1 and OpenGL ES 3.0 to be exposed for Apple Silicon M1/M2 SoCs under this Arch Linux based OS.

In addition to announcing the Apple Vision Pro AR headset, a 15-inch MacBook Air, and other new hardware, Apple lifted the lid on the M2 Ultra SoC. The Apple M2 Ultra is impressive from the technical specs and hopefully won't be too long before it begins working under Linux.

In addition to Linux 6.4 bringing some early work around the Apple M2 device support that isn't yet ready for end-users but begins laying the foundation for supporting the new MacBook Air, MacBook Pro, and Mac Mini, another set of Apple changes have now been submitted ahead of this next kernel cycle.

Further adding to the excitement of the upcoming Linux 6.4 merge window is the mainline kernel seeing the Device Tree (DT) additions for Apple's current M2 devices including the MacBook Air, MacBook Pro, and Mac Mini systems. The upstream kernel still has more work to go around the M1/M2 support compared to the downstream state with Asahi Linux, but at least now with this DT support will provide some basic level of upstream kernel support for the Apple M2.

A set of patches are expected to be merged for the Linux 6.4 cycle in two months enable support for the MMIO-based GMUX found on dual GPU Apple T2 Macs.

After being in development for several months, Asahi Lina with the Asahi Linux project has posted the initial Rust Direct Rendering Manager (DRM) subsystem abstractions for review as well as a preview of the experimental state of the AGX DRM driver providing the open-source kernel graphics driver support for Apple M1/M2 hardware.
