[Qemu-devel] [Bug 1231093] Re: qemu-system-arm does nothing but spin wheels

[Peter Maydell]

No, none of those people are using a kernel built for the rpi, because
that simply won't work. They will be using a kernel for versatilepb (or
some random hacked variant on it) plus the rpi filesystem image. This is
all a bit less than fully supported because the versatilepb board
doesn't actually have an 1176 CPU so when you say '-cpu arm1176' you're
making qemu emulate something that never existed, and whether Linux
works on that or not is a bit up to luck.

In general for troubleshooting you need to follow the same process you
would do for bringing up a kernel on real hardware devboards. This
typically involves using a debugger, looking at where the kernel has
fallen over and making some educated guesswork about what kernel config
options might need tweaking.

For this particular case you'll probably be better off asking in
raspberry pi forums or other places where the people who've already done
what you're trying to do hang out.

Title:
  qemu-system-arm does nothing but spin wheels

Status in QEMU:
  Invalid

Bug description:
  This was using 1.0.1 on fedora 17 then using 1.6.0 built from source
  with default configuration.   The host machine is x86_64 (intel i5)
  with a custom 3.11 kernel.

  'qemu-system-x86_64 -kernel [hostkernel]'

  Opens a window and shows the kernel booting.

  'qemu-system-x86_64 -kernel [arm11v6 kernel]'

  Opens a window with garbage in it.

  'qemu-system-arm -cpu arm1176 -M versatilepb -kernel [arm11v6 kernel]'

  Opens a window where nothing ever appears.   This kernel runs on a
  raspberry pi, so arm1176 should be appropriate; the '-M' option I
  noticed online.
