[Qemu-devel] [rfc 0/3] arm : dynamically choose initrd load address

[Daniel Lezcano]

Hi all,

after compiling my kernel on the arm architecture I was not able to
start it because qemu was segfaulting or going to an infinite loop.

After google'ing I found on launchpad the bug:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/524893

Following the indications, I rebuilt qemu with an higher initrd load
address and the kernel booted correctly.

I am trying to make the things easier and/or to fail gracefully with
patchset but I am not familiar with the ARM architecture neither qemu
internals, so may be I am totally wrong :)

The first patch raise an error if there is an overlapping error.
But the two next patches makes to compute automatically an address
for initrd to loaded.

Daniel Lezcano (3):
  arm : raise an error if the kernel size will overlap the initrd
  arm : factor out set_kernel_args[_old]
  arm : make initrd load address dynamic
