[Qemu-devel] [PATCH v3 00/20] Travis, Code Coverage and Cross Build updates

[Alex Bennée]

Hi,

Friday's code dump suffered a little from a rushed posting before the
weekend so I spent this morning cleaning up a few of the rough edges.
This version is much better for it:

  - Dropped .shippable changes

In the end it looks like building the ppc image won't work in
QEMU as it's pre-ci environment hasn't enough in it to build the
qemu-ppc linux user we need.

  - Better boostrap rule naming

The rule is now docker-binfmt-image-debian-% which means you can now
build any arbitrarily named debian-% image. If we are going support
similar binfmt bootstrapping for other distributions I suggest we
follow a similar scheme. Does anyone know if anything as funky as
debootstrap exists for anything else?

With a minor tweak to the debootstrap helper script you can now
boostrap Ubuntu images as well.

  - Dropped docker.py env hack (not needed)
  - Removed stray whitespace changes

The rest works as I outlined in the v2 message:

  I've picked up some more of Philippe's fixes and in the process had
  another look at the problem of cross compiling powerpc. In the end the
  consensus seems to be a linux-user build was the best solution as
  there are still supported native powerpc toolchains in Jessie (until
  2020). So I dusted off my old linux-user patches and tries to plumb
  them in a little better. Assuming you have ppc-linux-user in your
  target list and it's a --static you can just run:

    address@hidden TARGET_LIST=ppc-softmmu

  And it does the right thing. Once the debian-powerpc-user base image
  is created you can change your configuration and things will still
  work (until the debian-bootstrap recipe is changed and needs to be
  re-built).

It would be great if I could get reviews for the final few patches:

  patch 0011/docker filter out linux user builds for mingw.patch
  patch 0016/docker drop QEMU build dep from bootstrap.patch
  patch 0017/docker debian bootstrap.pre allow customising of .patch
  patch 0018/docker add special handling for FROM debian user .patch
  patch 0019/docker add special rule for deboostrapped images.patch
  patch 0020/docker add linux user powered cross builder for Q.patch

I'll send a pull request tomorrow for soft-freeze.
