[Qemu-devel] [PATCH 1/4] configure: qemu-ga: move MSI installer probe after qga probe

[Michael Roth]

MSI probe assumes that qemu-ga support has been probed already, but in
cases where --enable-guest-agent/--disable-guest-agent have not been
passed to configure, qemu-ga support may end up getting enabled later,
as is the case with w32 builds. This leads to MSI probe prematurely
reporting error due to lack of qemu-ga support.

Fix this by moving MSI installer probe after the final qga probes.

[Qemu-devel] [PATCH 2/4] configure: qemu-ga: explicitly enable qemu-ga MSI support when probed

[Michael Roth]

Currently, if we don't explicitly disable support for MSI installer
via --disable-guest-agent-msi, the configure variable that tracks
the flag, 'guest_agent_msi', never gets set unless one of the probes
fails. Subsequent code then treats this unset value the same as if it
were a "yes" value (via != "no" style checks).

Instead, set the default "yes" value explicitly after the probes, then
make subsequent code expect the values to be set.

This makes it easier to report on whether or not MSI support was
enabled via probe by looking at the ./configure summary.

[Qemu-devel] [PATCH 3/4] build: qemu-ga: fix VSS dependencies

[Michael Roth]

Currently VSS dll/tlb files for use in w32 builds are only built as a
result of having been added to the general 'tools' target alongside
qemu-ga. This is fine for default make target, but if we build
qemu-ga directly via `make qemu-ga.exe`, the VSS files are not
created.

Fix this by moving the VSS dependencies to qemu-ga.exe directly.
With this move we can move the VSS files back out of 'tools',
and drop the extra handling from MSI target in Makefile.

Now we can build qemu-ga MSI package with:
  ./configure ...
  make qemu-ga.exe
  make msi

or simply:
  ./configure ...
  make msi

and no longer need to do a full build beforehand.

Strictly this is not so great, but that makes sense: so perhaps a
small comment above to explain it would be good.

If we keep the $enabled != "no" logic all the way through, $enabled,
unless explicitly turned off or missing dependencies, will be
undefined when the configure options are summarized via:

  configure: qemu-ga: report MSI install support in summary

requiring the user to infer whether we'll default to "yes" or "no".
The current logic in fact defaults to "yes" in function, so with this
patch we're simply setting that flag early on so we can report "yes"
rather than undefined.

Will add a comment either way, but perhaps something like:

qemu-ga$(EXESUF): $(qga-obj-y) libqemuutil.a libqemustub.a $(QGA_VSS_PROVIDER)
       $(call LINK, $(filter-out $(QGA_VSS_PROVIDER), $^))

would be clearer? I suppose it's a bit more future-proof as well, if we added
more dependencies to QGA_VSS_PROVIDER for some reason.

Where is it reported? I don't see that in the configure summary, did
you add it in another patch?

[Qemu-devel] [PATCH 4/4] Makefile: qemu-ga: fix msi target error message

[Michael Roth]

'msi' target reports error if we attempt to use it when QEMU hasn't
been ./configure'd to enable it. The parenthesis cause an interpreter
error if we don't enclose the error in quotes.
