[kvm-devel] expose host CPU features to guests: Take 3

2007-09-24 Thread Dan Kenigsberg
As with previous "Takes" of this patch, its purpose is to expose host CPU features to guests. It proved rather helpful to KVM in various benchmarks, and it should similarly speed kqemu up. Note that it does not extend the set of emulated opcodes, only exposes what's supported by the host CPU. Anot

Hi, It's a pity not to use a host CPU feature if it is available. This patch exposes host CPU features to guests. It allows fine-tuning the presented features from the command-line. The code could use some serious clean ups, but I think it is interesting enough right now. I'd be happy to hear you
