The new Raspberry PI B 2 model got an armv7 core (the older ones are armv6), which makes it much easier to run Fedora on it. All Fedora packages are built for armv7, so they work as-is. Only things needed additionally are (a) the firmware and (b) a kernel. So I've packaged up the stuff. Firmware is just the binary stuff canned into rpms. Kernel is build from rapsberrypi git repo.
Install & usage
Just unpack the image and write it to a memory card. On first boot a rc.local script configures some things, then reboots the pi. root password is "pi". Network is configured use dhcp on both eth0 and wlan0, using systemd-networkd. wireless needs configuration though, use
wpa_passphrase "$ssid" "$psk" >> /etc/wpa_supplicant/wpa_supplicant.conf for that. kernel-rpi packages have a postinstall script updating
/boot/config.txt, so kernel updates work as usual.
There is a uboot-rpi2 package as I've played around with u-boot. Didn't found it that useful though. The firmware passes some command line args and a device tree to the kernel. With u-boot as boot loader inbetween that gets lost. So I've found myself facing problems by adding uboot to the mix, with no real advantages. Therefore the images don't use u-boot. But you can install the rpm and play around with it if you want.
Didn't came very far. Booting a kvm-enabled kernel in hyp mode isn't that difficuilt. The more serve problem is that there is no GIC which kvm needs too. Someone hacked up vgic emulation to solve that issue. But the patches are old and unmaintained. They don't rebase easily. And they also don't solve the problem that the machine has problems accepting hardware interrupts in guest mode. Which can be worked around with isolcpus & taskset. But after all it doesn't look like worth bothering ...
