Musing of a graphics witch
La plus grande ville d’un pays bilingue mérite le transport en commun bilingue. Vu l’intérêt prolongé pour la francisation de la ville reine, voici enfin un plan du réseau traduit. Il y a plusieurs ans, un internaut traduisit le plan du réseau de la Société de transport de Montréal . La règle est simple : traduire le nom de chaque station, soit de français en anglais, soit d’anglais en français.…
In 2020, Apple released the M1 with a custom GPU. We got to work reverse-engineering the hardware and porting Linux. Today, you can run Linux on a range of M1 and M2 Macs, with almost all hardware working: wireless, audio, and full graphics acceleration. Our story begins in December 2020, when Hector Martin kicked off Asahi Linux . I was working for Collabora working on Panfrost, the open source…
English version follows. Aujourd’hui, Khronos Group a sorti la spécification 1.4 de l’API graphique standard Vulkan. Le projet Asahi Linux est fier d’annoncer le premier pilote Vulkan 1.4 pour le matériel d’Apple. En effet, notre pilote graphique Honeykrisp est reconnu par Khronos comme conforme à cette nouvelle version dès aujourd’hui. Ce pilote est déjà disponible dans nos dépôts officiels.…
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. Plus a bonus: conformant OpenCL 3.0. Asahi Linux now ships the only conformant OpenGL® , OpenCL™ , and Vulkan® drivers for this hardware. As for gaming… while today’s release is an alpha, Control runs well! Installation…
Finally, conformant Vulkan for the M1! The new “Honeykrisp” driver is the first conformant Vulkan® for Apple hardware on any operating system, implementing the full 1.3 spec without “portability” waivers. Honeykrisp is not yet released for end users. We’re continuing to add features, improve performance, and port to more hardware. Source code is available for developers. HoloCure running on…
For years, the M1 has only supported OpenGL 4.1. That changes today – with our release of full OpenGL® 4.6 and OpenGL® ES 3.2! Install Fedora for the latest M1/M2-series drivers. Already installed? Just dnf upgrade --refresh . Unlike the vendor’s non-conformant 4.1 drivers, our open source Linux drivers are conformant to the latest OpenGL versions, finally promising broad compatibility with modern…
Conformant OpenGL® ES 3.1 drivers are now available for M1- and M2-family GPUs. That means the drivers are compatible with any OpenGL ES 3.1 application. Interested? Just install Linux! For existing Asahi Linux users, upgrade your system with dnf upgrade (Fedora) or pacman -Syu (Arch) for the latest drivers. Our reverse-engineered, free and open source graphics drivers are the world’s only…
Upgrade your Asahi Linux systems, because your graphics drivers are getting a big boost: leapfrogging from OpenGL 2.1 over OpenGL 3.0 up to OpenGL 3.1! Similarly, the OpenGL ES 2.0 support is bumping up to OpenGL ES 3.0. That means more playable games and more functioning applications. Back in December, I teased an early screenshot of SuperTuxKart’s deferred renderer working on Asahi, using OpenGL…
Today is my last day at Collabora and my last day leading the Panfrost driver. It’s been a wild ride. In 2017, I began work on the chai driver for Mali T (Midgard). chai would later be merged into Lyude Paul ’s and Connor Abbott’s BiOpenly project for Mali G (Bifrost) to form Panfrost. In 2019, I joined Collabora to accelerate work on the driver stack. The initial goal was to run GNOME on a…
We’re excited to announce our first Apple GPU driver release! We’ve been working hard over the past two years to bring this new driver to everyone, and we’re really proud to finally be here. This is still an alpha driver, but it’s already good enough to run a smooth desktop experience and some games. Read on to find out more about the state of things today, how to install it (it’s an opt-in…
Neverball rendered on the Apple M1 GPU with an open source OpenGL driver After a year in development, the open source “Asahi” driver for the Apple GPU is running real games. There’s more to do, but Neverball is already playable (and a lot of fun!). Neverball uses legacy “fixed function” OpenGL. Rather than supply programmable shaders like OpenGL 2, old OpenGL 1 applications configure a fixed set…
In late 2020, Apple debuted the M1 with Apple’s GPU architecture, AGX, rumoured to be derived from Imagination’s PowerVR series. Since then, we’ve been reverse-engineering AGX and building open source graphics drivers. Last January, I rendered a triangle with my own code, but there has since been a heinous bug lurking: The driver fails to render large amounts of geometry. Spinning a cube is fine,…
Exposure Notifications is a protocol developed by Apple and Google for facilitating COVID-19 contact tracing on mobile phones by exchanging codes with nearby phones over Bluetooth , implemented within the Android and iOS operating systems, now available here in Toronto. Wait – phones? Android and iOS only? Can’t my Debian laptop participate? It has a recent Bluetooth chip. What about phones…
(No, there won’t be jokes.) The following presents a fast algorithm for volume computation of a simple, closed, triangulated 3D mesh. This assumption is a consequence of the divergence theorem. Further extensions may generalise to other meshes as well, although that is presently out of scope. We begin with the definition of volume as the triple integral over a region of the constant one: \[V =…
