Subject: [Qemu-devel] [PATCH 0/2] QEMU maxcpus support v4
Date: Thu, 23 Jul 2009 17:03:41 +0200 [thread overview]
Message-ID: <20090723150341.281387164@sgi.com> (raw)
Hi,
Ok so this time I think i nailed the problem. Using Anthony's tree I
was able to reproduce the failure. Why it worked with my testing
previously I have no idea :-(
The problem was that the local processor APICs were not marked
disabled for the processors not being active. I also changed the code
to mark unused processors as disabled in the MP table, though that
seemed to have no impact on this particular failure.
With this version I can boot Ubuntu all the way to X using Anthony's
tree.
Sorry for the noise, I am still mystified :-(
Cheers,
Jes
