Subject: [Qemu-devel] [patch 0/2] QEMU maxcpus support
Date: Tue, 23 Jun 2009 12:00:09 +0200 [thread overview]
Message-ID: <20090623100009.827553739@sgi.com> (raw)
Hi,
This patch set adds the -maxcpus argument to QEMU and provides the
needed patches to the BOCHS patch queue to make the BIOS use it.
Specifying -maxcpus allows the user to cap the limit of possibly cpus
of the system, as opposed to -smp which specifies the number of
running cpus at startup. This allows us to build BIOS tables
accordingly when trying to scale up in size, and it also allows for
the BIOS to build smaller tables when not needed.
I am going to submit a set of patches directly for BOCHS as well
covering the BIOS part, but I am still waiting for my bochs-developers
subscription to be enabled.
Avi asked me to post this both for QEMU and the BIOS part for BOCHS.
Cheers,
Jes
