[Qemu-devel] [Bug 1840777] Re: raspi3 machine can not shutdown

[Alex Bennée]

I'm guessing from:

  bcm2835-pm: unimplemented device read (size 4, offset 0x20)
  bcm2835-pm: unimplemented device write (size 4, value 0x5a000555, offset 0x20)
  bcm2835-pm: unimplemented device write (size 4, value 0x5a00000a, offset 0x24)
  bcm2835-pm: unimplemented device read (size 4, offset 0x1c)
  bcm2835-pm: unimplemented device write (size 4, value 0x5a000020, offset 0x1c)

That we don't implement the power control parts of the SoC and therefor
the kernel got to a bit it wasn't expecting.

  Running "shutdown" within a raspi3 image leads to kernel panic:
