Hi Avi, here's the latest batch of PowerPC kernel patches. The first set dramatically improve performance. Most importantly, we add support for large host pages with KVM (i.e. PAGE_SHIFT > 12). (Large *guest* pages have already been supported since day 1, since the guest kernel uses them for the linear map.) Followup patches further improve performance by changing how we manage the shadow TLB.
The last two add some accounting code to easily discover performance bottlenecks. This is especially important since the 440 core lacks performance monitoring hardware. These patches, in conjunction with 64KB pages on guest and host, get us to 96% of native performance for compute-bound workloads, which I'm pretty happy with. See http://kvm.qumranet.com/kvmwiki/PowerPC_Exittimings for more details (those statistics were gathered using the accounting patches). These have been tested pretty thoroughly for several weeks. Please apply for 2.6.29.
