lyssaon Asahi Linux for M1 Macs: progress report for September 2021

The DCP firmware has multiple endpoints. Currently, we only use and understand the main endpoint, which lacks raw I2C/DDC/EDID interfaces. Presumably this is available on another endpoint, but we haven't looked at this yet. Your gist gives me hope.

The HDMI port on the Mini is funny. The M1 supports exactly one internal display (the panel on a MacBook or iThing) and one external display (over DisplayPort/Thunderbolt). This is why M1 MacBooks can only drive a single external monitor.

For the Mini, the "internal" display is an internal DisplayPort connection, converted to HDMI with a mcdp29xx chip, and stuck on the HDMI port. Expect weirdness.

Hey, if you're running Linux, you're using my drivers either way ;-)

Now back to typing away at Panfrost on my M1 Linux to debug an issue on the Odroid N2 I have Ethernet connected to the M1...

No, this is purely a hobby project undertaken in my spare time. (The email addresses on the git commits are force-of-habit, apologies for the confusion.)
