It has hardware IRQ muxing, this is the driver (https://github.com/smaeul/linux/commit/16eafe2078ebe9306d095abc450585c2417db066 https://github.com/smaeul/linux/

- ahlCVA 3y agoI missed that development, thanks! As I understand it, it's not strictly muxing per se - you're basically siphoning off the interrupts from the M0 core using a hardware mechanism instead of firmware + IPC, so any firmware you might want to run on the M0 core still needs to be careful not to mess this up. But it's still an improvement.
