[Qemu-devel] [PATCH] x86: Show model_id in CPU list.

[Qemu-devel] [PATCH] x86: Show model_id in CPU list.

[Nathan Baum]

Shows the model_id in the CPU list:

$ qemu-system-x86_64 -cpu ?
x86           qemu64  QEMU Virtual CPU version 0.11.50
x86           phenom  AMD Phenom(tm) 9550 Quad-Core Processor
x86         core2duo  Intel(R) Core(TM)2 Duo CPU     T7700  @ 2.40GHz
x86            kvm64  Common KVM processor
x86           qemu32  QEMU Virtual CPU version 0.11.50
x86          coreduo  Genuine Intel(R) CPU           T2600  @ 2.16GHz
x86              486 
x86          pentium 
x86         pentium2 
x86         pentium3 
x86           athlon  QEMU Virtual CPU version 0.11.50
x86             n270  Intel(R) Atom(TM) CPU N270   @ 1.60GHz

No particular reason for it; just thought it could be considered useful.

As an aside, is it intentional that "athlon"'s model_id describes it as
a generic Qemu CPU?

I fixed that already in the CPUID rework patch series I sent out 10 days 
ago:
http://lists.gnu.org/archive/html/qemu-devel/2009-09/msg01236.html

Anthony's staging tree (http://repo.or.cz/w/qemu/aliguori-queue.git) has 
been pretty stale for the last 2 weeks, so if my patch series should be 
applied before your patch, you have to rework your's (should be almost 
trivial, see patch 08/21).

Regards,
Andre.
