Are you running 32-bit or 64-bit rawhide? I am running 64-bit rawhide
(Fedora-Workstation-Rawhide-20200110.n.0.aarch64.raw.xz) on my RPi4.
It works well - mouse, keyboard, sd card, ethernet, basic HDMI are all good. I did
have to add one line to /boot/efi/config.txt:
disable_overscan=1
Without that, I had a black border on my monitor. Once I added the above line and
rebooted, the display looked good. No accelerated graphics, but that is ok for me right
now.
I only want to use the RPI4 as a server with UBI (and this aarch). Are you having 4 GB of
usable memory (as a lot of people only get 3 GB)?
I also just read RPI4 HW support is in the just released 5.5 kernel. Wonder if 5.5 will
be in rawhide..
Rawhide already has kernel 5.5:
pif# uname -a
Linux
pif.optonline.net 5.5.0-0.rc6.git2.1.fc32.aarch64 #1 SMP Wed Jan 15 20:23:38 UTC
2020 aarch64 aarch64 aarch64 GNU/Linux
I have very close to the full 4 GB of ram available. According to dmesg, 256K of ram is
not available - it might be assigned to the video core:
Memory: 3833660K/4096000K available (12924K kernel code, 5450K rwdata, 6272K rodata, 6272K
init, 26849K bss, 229572K reserved, 32768K cma-reserved)
