[PATCH v10 0/7] build upstream qemu and seabios by default

Hi all,
this is the tenth version of the patch series to introduce upstream qemu
and seabios in the xen-unstable build system.

Changes to v9:

- rename QEMU_UPSTREAM_TAG to QEMU_UPSTREAM_REVISION: we are going to
use it with a branch name by default;

- set QEMU_UPSTREAM_REVISION to "master" by default;

- set SEABIOS_UPSTREAM_URL to git://xenbits.xen.org/seabios.git by
default;

- add a patch to update MAINTAINERS.


Changes to v8:

- build upstream qemu out of tree;

- add a tools/qemu-xen-dir-force-update target;

- add a tools/firmware/seabios-dir-force-update target;

- call make install from subdir-all and subdir-install
qemu-xen-traditional and qemu-xen targets; 

- fix a typo in patch #5;


Changes to v7:

- call upstream qemu''s configure script right before building qemu and
after building libxc and xenstore because it needs them;

- introduce a new patch to move the call to xen-setup after building
libxc and xenstore for consistency with upstream qemu;

- fix a typo in tools/Makefile (patch #4);


Changes to v6:

- add "set -e" to git-checkout.sh;

- add argument count check to git-checkout.sh;

- remove spurious semicolons in git-checkout.sh.


Changes to v5:

- use $GIT in git-checkout.sh;

- add an http mirror for seabios;

- use $(LIBEXEC) to configure upstream qemu;

- append a patch for libxenlight to find the upstream qemu binary under
$(LIBEXEC).


Changes to v4:

- remove an obsolete comment;

- use /bin/sh to execute git-checkout.sh rathen than /bin/bash.


Changes to v3:

- reduce the scope of git-checkout.sh, now it only does what the name
says; calling "configure" is responsibility of the caller. As a result
of this change, the build still works when the user specifies a local
directory in the CONFIG_QEMU environmental variable;

- use a more official qemu repository hosted on xenbits;

- use a changeset as QEMU_UPSTREAM_TAG rather than a branch name.



Changes to v2:

- move tools/git-checkout.sh to scripts/git-checkout.sh;

- use git-checkout.sh for seabios;

- improve seabios integration with tools/firmware make system;

- add qemu-xen-traditional, qemu-xen and seabios dir entries to
.hgignore.



Changes to v1:

- always build upstream qemu and seabios, rather than introducing them
as an option.


Cheers,

Stefano

[PATCH v10 3/7] move the call to xen-setup after libxc and xenstore are built

From: stefano.stabellini@eu.citrix.com <stefano.stabellini@eu.citrix.com>

Move the call to xen-setup, the wrapper script to configure
qemu-xen-traditional, right before building qemu-xen-traditional and
after libxc and xenstore are already built.

Thanks.  This all looks good and I intend to apply it as soon as we
get a push in xen-unstable.  (Until then I''ll wait in case it breaks
the build and makes it harder to get a push.)

The actual installed path (in staging tree now)
is /usr/lib/xen/bin/qemu-system-i386 so if I boot a guest with
device_model_version="qemu-xen" then, as you might expect, I get:
        libxl: error: libxl_dm.c:809:libxl__create_device_model: device model
/usr/lib/xen/bin/qemu is not executable: No such file or directory
        libxl: error: libxl_create.c:579:do_domain_create: failed to create
device model: -3
        libxl: error: libxl_dm.c:926:libxl__destroy_device_model:
Couldn''t find device model''s pid: No such file or directory
        libxl: error: libxl.c:796:libxl_domain_destroy:
libxl__destroy_device_model failed for 21

I can add device_model_override="/usr/lib/xen/bin/qemu-system-i386"
and
then things work as expected.

Presumably if I build my tools for 64 bit it will be qemu-system-amd64.

So, should we fix libxl, the qemu build or our build integration?

Ian.

It is always qemu-system-i386, unless we change the target in the
configure line. Of course it doesn''t really matter for us because we
don''t use it for cpu emulation.

The binary name changed for the 1.0 release, I don''t expect it to
change
again. I think we should update libxl.
