Subject: [Qemu-devel] Performance regression "ioport: Switch dispatching to memory core layer"
Date: Mon, 15 Jul 2013 18:52:20 +0800 [thread overview]
Message-ID: <CAJSP0QU3awmkm-LBnjFm=_uds3JHQJUVXOnELjodFihq5hZfmg@mail.gmail.com> (raw)
The following qemu.git commit adds a ~2 minute regression in boot time
to a x86_64 live CD:
commit b40acf99bef69fa8ab0f9092ff162fde945eec12

ioport: Switch dispatching to memory core layer
After the ISOLINUX menu, the display goes white and sits there for about
2 minutes on my laptop before the usual Linux boot screen appears.
$ qemu-system-x86_64 -enable-kvm -cpu host -m 1024 -cdrom ~/iso/livecd.iso
The parent commit immediately goes to the usual boot screen after
ISOLINUX. Unfortunately I don't have a ISO download link for the live
CD.
Any ideas?
Stefan
