Does the amd64 kernel know anything about which memory is attached to which processor, and which i/o bus is attached to which hypertransport link? Can it use this information to do things like allocate pages to a process from the memory that is physically attached to the cpu upon which the process is running? Along these lines, is there any way to set affinity between a process and a cpu (or set of cpu's in the case of multicore)? Likewise with i/o devices, if a process or device driver wants to operate a particular device, can it be set to run on the cpu that owns the hypertransport connection upon which the device is connected? thanks, ron.
