Add support for the Raspberry Pi 5

[stapelberg]

This issue tracks the progress. Currently, the Pi 5 is not in stock.

Here’s some background info: https://www.jeffgeerling.com/blog/2023/answering-some-questions-about-raspberry-pi-5

First draft of a checklist:

• serial port working
• kernel booting
• gokrazy init running
• fan control working
  • fan always runs, not sure why. tried dtparam=cooling_fan=off in config.txt, and also =on with PWM fan parameters, but no change in behavior with either of those attempts
• poweroff / reboot working
  • HDMI signal is lost on reboot
• encrypted WiFi working
• crypto acceleration working

I'm happy to help testing on my freshly arrived Pi 5 once you're starting to work on it.

[stapelberg]

My first Pi 5 arrived 🎉

When I just try to boot a current gokrazy installation, I get the following error message by the bootloader:

When I set os_check=0, I don’t get any HDMI output.

I would have checked the serial port, but I don’t get any output on the GPIO header. I ordered a Raspberry Pi Debug Probe to use the JST port.

[damdo]

Exciting! Happy hacking, let us know how it goes :)

[stapelberg]

The Debug Probe arrived, so now we can see the serial output of the entire boot process.

For the attempt with os_check=0 in config.txt, output just stops before the Linux kernel ever prints a line.

I then tried dropping https://github.com/raspberrypi/firmware/blob/master/boot/bcm2712-rpi-5-b.dtb into the kernel directory.

This made it go a whole lot further, in that the bootloader recognizes the installation as compatible, we see Linux kernel output, but then the boot hangs when it tries to find the root device:

So, my guess is that we need to sort out the following issues:

• upstream the device tree changes so that Linux builds a (working) bcm2712-rpi-5-b.dtb
• make sure the mmc driver works.
  • The Raspberry Pi kernel seems to use bcm2712-sdhci, but that’s probably not in the upstream kernel yet.
  • Maybe the driver currently in upstream Linux works as well, or maybe the other one needs upstreaming.
• make sure the ethernet driver works
• make sure the USB driver works

[stapelberg]

Looks like https://forums.raspberrypi.com/viewtopic.php?t=360653 is the most recent post regarding Pi 5 upstream work, and there is a patch series to try out, but ethernet and USB don’t work yet apparently.

Seems like we need to be patient for a few more weeks at least…

[stapelberg]

Status update: 6by9, the person working on upstream support for the Pi 5, reports that it will take quite a long time because of a DMA-related long-standing misunderstanding in the kernel that’s hard to fix: https://forums.raspberrypi.com/viewtopic.php?p=2202581&sid=d2fbe43c5b4e9f133bf7842210a19d7d#p2202581

[damdo]

Thanks for the update @stapelberg
Hopefully they'll be able to figure it out 🤞
