It looks like arch->vcpu.pvr is totally uninitialized right now. (I'm surprised the guest hasn't complained.) Instead of setting it from userspace, could you send a patch that initializes it to the hardware's PVR value? It's a simple patch, and you can use that to disambiguate the TLB stuff in later patches. We can discuss the best way to handle this long term, but right now I think virtual IO is more important. -- Hollis Blanchard IBM Linux Technology Center ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
