Subject: [Qemu-devel] [patch 0/2] QEMU maxcpus support v2
Date: Wed, 24 Jun 2009 10:35:12 +0200	[thread overview]
Message-ID: <20090624083512.766907560@sgi.com> (raw)

Hi,

Here is an updated version of the ,maxcpus patch, now adding it as a
sub-option to -smp, ie, -smp <n>,maxcpus=<y>. In addition it has the
QEMU BOCHS patches to make the BIOS use the value passed.

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.

Cheers,
Jes
