A true mainline Linux Kernel for the Pinebook Pro

Sorry. This has not really been my main focus. My defconfig does not enable a 32 bit userland. However you can easily do so by setting CONFIG_COMPAT to y.

How is WiFi testing going? Did you experience any crashes since switching to the other firmware?

Most everything can stay at 32 bit. But, somethings may work better at one or the other.

Sure. Enabling it in the kernel is easy. However, ARMv8 code will have significantly better performance. Thus only applications that do absolutly need to be run as 32 bit binaries like widevine should be run in compat mode.

I built the defconfig, copied the Image and DTB onto /boot, modules into /lib/modules. It starts to boot, and then I see serial output, but suddenly after the following, it becomes garbage:

[   12.051588] OF: graph: no port node found in /i2c@ff3d0000/fusb30x@22
[   12.065983] OF: graph: no port node found in /i2c@ff3d0000/fusb30x@22/connector
[   12.068329] OF: graph: no port node found in /i2c@ff3d0000/fusb30x@22/connector

Has anyone else seen this? I'm using the 1500000 baud rate, and that works fine for u-boot output and early kernel output until this point. I've tried a few other common baud rates at this point, but nothing shows reasonable output.

Yes, I've seen that before. There is probably no connection between the messages and the weird baudrate though. I've had my pinebook use weird baudrates before. Due to differences in libkmod the debian userland might be unable to load modules compiled from my kernel tree. That might be why your system is not working as expected. I'd suggest installing Manjaro to a Micro SD Card or even the eMMC flash. There the kernel will work properly.
