[Qemu-devel] Checking the state of arm64-linux-user

[Qemu-devel] Checking the state of arm64-linux-user

[Alex Bennée]

Hi Michael,

I'm currently at Linaro Connect and am looking at running the arm64
stuff through Peter's risu tool and getting an idea of the instruction
coverage. Alex pointed me to:

https://github.com/susematz/qemu/tree/aarch64-1.6

Which I've been looking at building. I'm hitting a bunch of issues while
building. They are mostly -Werror bits and pieces which I can work
through but as it doesn't build with the default QEMU build options I
thought I'd better check if that is the correct latest/greatest version
of the patch set.

Regards,

With my upstream-qemu-arm-maintainer hat on, I would suggest that
the thing we should be building and testing is the most recent set of
patches that has been submitted to the mailing list. I think Alex said
doing a v2 of that is on his todo list...

I think the problem is arm64 has been posted in several dependant patch
sets hence working from a git tree. I think for now I'll take off the
-Werror training wheels and see how far it gets.

However if you have any pointers to patchwork I can build a tree from
there as well.

http://lists.nongnu.org/archive/html/qemu-devel/2013-09/msg04503.html

is Alex's patchset which he rebased on to a qemu master,
so if you can't wait for v2 then that's the one to look at.

Alex's patchset covers only the first part of the whole thing, and so 
misses some instructions and fixes.  If you merely want to use 
qemu-arm64 you're better off using the tree from me.

Alex B.: I'm building that tree with gcc 4.7 and this config:
% ../configure --disable-system --enable-linux-user --disable-werror \
  --static --disable-linux-aio --disable-strip \
  --target-list=arm64-linux-user
% make


Ciao,
Michael.
