Hello, long time ALARM user, but first time I actually need to post on the forums.
This is my current setup:
$this->bbcode_second_pass_code('', '# ~ cat /proc/device-tree/model
Raspberry Pi 4 Model B')
$this->bbcode_second_pass_code('', '# ~ uname -a
Linux phi 5.15.5-1-ARCH #1 SMP Wed Dec 1 01:26:36 UTC 2021 aarch64 GNU/Linux')
$this->bbcode_second_pass_code('', '# ~ pacman -Q {linux,uboot-raspberrypi}
linux-aarch64 5.15.13-1
uboot-raspberrypi 2021.04-1')
Much like this thread, it does seem like I'm not getting access to the VC4 graphics.
$this->bbcode_second_pass_code('', '# ~ ls /dev/dri
total 0
drwxr-xr-x 2 60 Jan 8 22:41 "by-path"
crw-rw---- 1 226, 0 Jan 8 22:41 "card0"')
The solution seems to be to migrate to the linux-rpi kernel. Is this correct? If so, what is the procedure? Do I need to uninstall linux-aarch64 and uboot-rasbperrypi, and install linux-rpi, and that's it?

Another question is that I'm getting every so often a few log entries regarding IRQs, like this one:
$this->bbcode_second_pass_code('', 'Jan 08 22:40:47 phi kernel: irq 10, desc: 00000000d4a9d25c, depth: 0, count: 0, unhandled: 0

Jan 08 22:40:47 phi kernel: IRQ_NOTHREAD set')
I still haven't figured out what's causing them, since the installation is fresh. Should this be a worry?
Thanks for the help.
