Introduce a new '-p/--pcpus' flag to display physical CPU utilization metrics using xc_interface. This provides hypervisor-level CPU usage insights alongside existing domain statistics. This helps correlate VM resource usage with host CPU load patterns. Changes: - Add pcpu.c/pcpu.h for PCPU stat collection logic - Link against libxenctrl for xc_handle access - Extend CLI with '-p' flag and output formatting - Forward declare xenstat_handle to access xc_handle - Include cleanup for PCPU resources in exit handler Example usage: xentop -p # Shows physical CPU stats xentop -bp # Batch mode xentop -d 1 -p # With different delays Example output with '-p': NAME STATE CPU(%) MEM(%) VCPUS ...
