The only thing in the current ioctl code that doesn't make sense for PowerPC is the rmap stuff. The concept of "slots" as memory extents is just fine. Originally, I think the only question was how to register the slots on the kernel side. Today that is done with separate KVM_SET_USER_MEMORY_REGION ioctls, one for each guest physical region. Izik's idea (as I understand it) is to have one ioctl registering all of RAM, and then multiple "configure slot" ioctls that tell the kernel how to divide that area into the guest physical address space. That seems more awkward to me and I don't seem a benefit. -- Hollis Blanchard IBM Linux Technology Center ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
