From be9562bdb0bef5b3e8db7dd22104631f13188f3a Mon Sep 17 00:00:00 2001 Message-Id: From: =?UTF-8?q?J=C3=A1n=20Tomko?= Date: Tue, 16 May 2017 10:44:53 +0200 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. https://bugzilla.redhat.com/show_bug.cgi?id=1427005 (cherry picked from commit 6b5c6314b2f7a3b54c94a591e6b0dcd13ef1c6ce) Signed-off-by: Ján Tomko Conflicts: tests/qemucapabilitiesdata/caps_2.9.0.x86_64.xml - downstream did not update the qemu version to 2.9.0 Signed-off-by: Jiri
