What do you think this will do for the GPU support though? There are a couple mali architectures now that support OpenGL ( Bifrost https://wiki.debian.org/PanfrostLima )
I'm out of practice, but I was once tinkering with an Allwinner A80 with a PowerVR GPU, and there was OpenGL support in the proprietary binaries, somewhere.... I gave up. It does Open GLES and sits in a drawer until I think of what to do with it
or do you think they'll adopt NVIDIA (like the jetson nano)? NV already puts pci-e (some lanes) on its jetsons with arm cores, so in a few more cycles, maybe there will be enough on-chip to support all the connectors, network stuff that apple puts on laptops/desktops
And there was that fusion CL/GL API they wanted to put out called Metal. I haven't followed along with its progress. Is it related?

Howdy all,
Apple announced today that it will transition from Intel to its own Arm processors. What this will bring is:
- Universal 2: x86_64 & arm fat binaries
- Rosetta 2: emulation layer from x86_64 to arm
For Pd, this means that current binaries will most likely *run* but who knows how the performance will be good for realtime DSP. OTOH, they did demo a game and some virtualization support so it seems they have focused on making things run as well as they can.
Building Pd itself for macOS arm should be relatively easy, just a different arch target. For externals, this would may require an additional fat lib type, perhaps dfat_2? Note, I believe the distinction will be important for us since we still have "Universal 1" builds. As with the Pd core, updating pd-lib-builder should also be relatively easy by adding the new arch targets, depending on what they are.
For deken, this means recompiling and uploading the new fat type.
I don't imagine it will be possible to have a "fatter lib" which supports ppc, x86, x86_64, & arm. I believe the writing is on the wall for the eventual need for a build system newer then OS X 10.6.
