       New blog post: PanVK Extension Sprint - Mesa 26.1 🚀18 Vulkan extensions landed in PanVK for Mesa 26.1 - the open-source Vulkan driver for Arm Mali GPUs. Covering the Proton stack essentials (DXVK, vkd3d-proton), DDK feature parity, and closing gaps on mesamatrix.From VK_EXT_conditional_rendering to VK_EXT_nested_command_buffer - each one pulls PanVK closer to "throw a DXVK game at it and it just works."https://christian-gmeiner.info/2026-04-20-panvk-extensions/#Mesa #Vulkan #PanVK #Panfrost #Mali #Igalia

       You've probably seen kmscube before - but every screenshot of it is a milestone someone reached. Last night I hit one of those moments, after many years (again).For the past months I shifted focus away from GLES3 to some foundation work that had to be done.On the photo: kmscube running on the long-in-development new compiler backend, used for both the vertex and fragment shader.#etnaviv #mesa3d #rust #mntreform #librem5

       I built infrastructure to validate ISA-specific behavior on hardware against a `Foldable` CPU reference - the idea is straight out of NAK by @gfxstrand . Write the per-opcode reference once, run a matrix of cells (src mods × swizzles × write masks) on the GPU and compare.It saved me so much guesswork about how each ISA instruction behaves with input values and rounding modes - hello subnormal IEEE 754 pain.I should have started this earlier.#etnaviv #mesa3d #rust #mntreform #librem5

       dEQP-GLES3, old etnaviv compiler vs new one: +6140 passes, −3004 crashes. 🚀#etnaviv #mesa3d #rust #mntreform #librem5

       @mntmn It’s a nice little development setup that I can carry around with me. It has even made it to a few trade fairs. 🙃
