It works just fine for the server type use cases, I improved a lot of
the early boot process and stabilised a number of pieces of the early
boot as part of F-34, there's still no accelerated graphics, until
that lands I won't mark it as supported as it generates too many
support queries.

Is RPi4 support documented anywhere?
I have wanted to test running Fedora Server, but never did as going from
the ARM page [0] to the linked documentation [1] to the RPi4 [2] and it
just says that it's not supported (as of 30 October 2019).

I would be interested in testing Fedora Server on an RPi4 if it's

In most cases for things like Workstation/Server they're on the main
pages, for other pieces they're linked from the Alternate
Architectures page [1] which is linked from near the Spins/Labs but
overall it's quite disjointed and could likely just be linked directly
from the various spins pages.

This particular bug also impacts aarch64, which led me down the rabbit

The marketing[0] certainly implies to me armhfp is a main Fedora product 
even if it's not a blocker in QA terms, it's what all the "Desktop 
Computing" download links point to which has Workstation at the very top.

I can't speak to "immediately obvious documentation", but it's worth
remembering that Workstation on 32-bit ARM is not release blocking by
policy. See:
https://fedoraproject.org/wiki/Releases/34/ReleaseBlocking
the only release-blocking 32-bit ARM image left is minimal, and the
release criteria preamble state:
"The current set of release-blocking desktops for x86_64 is GNOME and
KDE, and for aarch64 is GNOME. No desktop is release-blocking for 32-
bit ARM."
https://fedoraproject.org/wiki/Basic_Release_Criteria#Basic_Release_Requirements

If there is documentation or marketing that gives the impression that
Workstation on 32-bit ARM is some sort of
priority/"supported"/recommended/blocking/whatever environment, it
should be changed.

This brings up my major frustration with Fedora on ARM since I've
started poking at it. A "regular user" wanting to run Fedora on their Pi
is going to go to the Fedora ARM landing page[0]. That page doesn't make
it immediately clear what works on what hardware. If the user doesn't
give up, they may scroll down and see the Documentation link and follow
it to the Fedora ARM wiki page[1]. Scrolling there they will see
"Supported Hardware and Devices" with "Raspberry Pi" right on top. That
page[2] repeatedly lists Workstation as supported on the 3B+, in the
introduction, under supported hardware, under pre-requestites (where a
video cable is suggested, implying something other than minimal should
work), and as explicitly under supported images. No caveats are given.

End rant. I really am appreciative of Fedora on ARM. Thanks for listening.


Maybe if you'd bought this up in an appropriate place, such as the arm
mailing list or the weekly meeting we could address it, or maybe just
ask the status and people's thoughts on IRC and see what the status is
and whether it makes sense to updating the documentation for these
devices and then volunteering to do it for the arm team?

Peter


I apologize if I stepped on any toes, but I see this as a QA issue. I 
will gladly update documentation (and I do so when I find mistakes in 
the documentation). But if we're going to heavily suggest hardware is 
supported, that means I'm going to run test cases against it (which I 
did). If they fail, I'm going to file bugs (which I did). If that 
failure violates a release criteria (it does) I'm going to try to see 
how common it really is (probably should have been on the ARM list 
admittedly, but I already have issues keeping up with all my e-mail, 
Fedora related or not, and I really don't have time to linger on IRC). 
If it's a one off, I shrug and move on.


Since this is apparently a known caveat, I posted my rant. Which I 
shouldn't have done. Feel free to tell me how if want the Wiki pages 
modified to make it clear Workstation is not expected to work on the 3B+.

There's the RPi4 that will work in 32 bit mode and it is available
with 2-8gb of RAM, there's i.MX6 devices with 2+gb of RAM, there's the
Jetson TK1 and related devices that have 4Gb of RAM as well as the arm
based OLPC devices which have between 1 and 4Gb of RAM depending on
the SKU.

The RPi3 works with XFCE, Sugar and others quite well, the issue with
Workstation on that device is the GPU allocates 256Mb of the available
1Gb to CMA for V-RAM which means in fact you have significantly less
than 1Gb of RAM.

Thanks for following up. I was mostly trying to gauge if this was common 
enough it should be a proposed blocker.


Now, not to be a stick in the mud, but what other common armhfp hardware 
is out there? If the Pi 3B+ isn't "up to the task", perhaps desktop 
images that aren't expected work should just be dropped? I'm not sure a 
desktop environment running on armhfp in a VM is that common of a use case.


We're now looking at publicly releasing a version of Fedora that 
apparently just doesn't work when all immediately obvious documentation 
implies it should.


This brings up my major frustration with Fedora on ARM since I've
