Code:
DEBUG: CRBP::OpenDisplay device:0 m_display:0 (0)
OpenDisplay requires correct /opt/vc/lib, kernel and firmware.

Not sure how arch gets /opt/vc/lib but it may be worth trying with this: https://github.com/raspberrypi/firmware/...opt/vc/lib

Arch uses that source for the firmware: https://github.com/archlinuxarm/PKGBUILD...GBUILD#L16
Currently shipping commit cba4be27.

I think I found a part of problem: my /boot/config.txt was:
Code:
initramfs initramfs-linux.img followkernel
gpu_mem=320
dtparam=audio=on
dtoverlay=vc4-fkms-v3d

Upon booting, my monitor was in some crazy low res mode so I added these lines and rebooted:
Code:
hdmi_group=2
hdmi_mode=69

I noticed that did not take effect so I re-read this document which talked about differences between HDMI0 and HDMI1. I moved the plug into HDMI0 and now playing the low res sample works with and without MAAL enabled! I'm going to speculate the Kodi was playing to HDMI0 but that wasn't connected.

Without MAAL enabled log.
With MAAL enabled log.

So progress!

BUT, still not 100%. I cannot play the x265 clip which you can get here.

Here is the log trying to play it. When I try to play it, the GUI just freezes for about 30 sec before systemd restarts my kodi.service. Note that this clip plays under LE. Any thoughts are welcomed!

Have you got the right permissions on /dev/argon-* ?

Thank you!  That solved it!  Here is the debug log playing the file successfully.

This my current 99-kodi.rules ... does it look sane?  Missing anything?
Code:
SUBSYSTEM=="bcm2835-gpiomem", GROUP="gpio", MODE="0660"
SUBSYSTEM=="bcm2708_vcio",GROUP="video",MODE="0660"
SUBSYSTEM=="argon-*", GROUP="video", MODE="0660"
SUBSYSTEM=="vc-sm",GROUP="video",MODE="0660"
SUBSYSTEM=="vchiq",GROUP="video",MODE="0660"
SUBSYSTEM=="tty", KERNEL=="tty[0-9]*", GROUP="tty", MODE="0660"

I will opened a separate thread to tackle the final obstacle to getting this fork to build. Thanks again!
