RPi 4

[Steven A. Falco]

I know that the RPi 4 is not currently supported in Fedora, while we wait for upstream kernel support for the new Broadcom BCM2711 SOC.

However, I now see that there is some support for the BCM2711 in kernel 5.5, and I also see that kernel 5.5 is in rawhide.

Thus, I'm wondering if that is sufficient to start talking about Fedora on the RPi 4.

I'm currently running Manjaro on my RPi 4, because they have an aarch64 version, and I wanted an aarch64 machine to experiment with.

I'm not sure if the Fedora ARM team plans to support both 32-bit and 64-bit mode on the RPi 4, so any information about that would be appreciated.

I'm interested in helping out.  If there is something I can do, please let me know.

It's being worked upon. Ultimately I don't tend to talk about it
widely because most Raspberry Pi users complain if it's not perfect
with accelerated graphics and a whole bunch of other features and I
end up with more support requests than I can cope with.

Well I do most of the RPi enablement, and yes, it's intended to
support it in similar ways to the way we support the RPi 2/3 devices.

What are your capabilities to help out? Are you a kernel developer,
user space developer etc?

I understand - I recognize that this is a new chip, and it will take some time for full support to make it into the upstream kernel.  I certainly don't want to add any work or hassle for anyone.

In the past I had done some kernel driver and u-boot work, mostly for Freescale PowerPC chips on proprietary boards.  I currently have a few Wandboards with some custom hardware added, running yocto (an ntp clock and a weather station project), so I am familiar with device trees on ARM.

I don't have access to anything beyond the public documentation for the RPi 4.

I'm not sure how the Fedora ARM images are generated, but in the past I used lorax and pungi to generate respins of CentOS 7.

Hello,

why is RPi 4 supported on Ubuntu early than in Fedora? Is there any
different in kernel in Ubuntu?

Yes, they use random vendor forks.
