Subject: [PATCH] qemu: format kernel_irqchip on the command line
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Add kernel_irqchip=split/on to the QEMU command line
and a capability that looks for it in query-command-line-options
output. For the 'split' option, use a version check
since it cannot be reasonably probed.

(cherry picked from commit 6b5c6314b2f7a3b54c94a591e6b0dcd13ef1c6ce)
Signed-off-by: Ján Tomko <jtomko@redhat.com>
Conflicts:
tests/qemucapabilitiesdata/caps_2.9.0.x86_64.xml
- downstream did not update the qemu version to 2.9.0
