Hey all,
Just trying the F21 beta (and Fedora-Minimal-armhfp-21-20141117-sda.raw)
under
qemu. Seems like these versions both require explicitly passing in a dtb to
qemu to actually boot. Well, maybe it's booting and I'm just not getting
any
serial output, can't really tell.
Passing a dtb to qemu wasn't required for the F20 GA release at least, and
still isn't required with F21 qemu-system-arm, so presumably it's not a
qemu
regression.
Fedora 21 requires the use of a dtb to boot the multiplatform kernel. This changed
around the 3.16 RC's (iirc).
Having to pass a dtb is kind of a pain for management tools, it's another
file
that needs to handled. And the docs say it shouldn't be required:
https://fedoraproject.org/wiki/Architectures/ARM/F21/Installation#For_Versatile_Express_Emulation_with_QEMU
Thanks, I will adjust the page.
Medium/long term we should consider changing the docs to recommend using
qemu-system-arm -M virt, since that's where all the virt improvements are
generally going to take place, and it doesn't require an explicit dtb (since
it generates ones behind the scene). That will also be the virt machine type
used for aarch64, so it will be nice to have parity there.
