title: Tally the Number of User-Space QEMU IO on Each IO Port name: qemu_io.stp version: 1.0 author: William Cohen keywords: virtualization qemu kvm io subsystem: virtualization status: experimental exit: user-controlled output: sorted-list scope: system-wide description: The qemu_io.stp script tallies the number of times each of the IO port on the guest virtual machines is touched by a input or output operation. When the script exits, it prints a count of the number of times each IO port read and written. test_support: stap -l 'qemu.*.*.cpu_in?, qemu.kvm.cpu_in?' && stap -l 'qemu.*.*.cpu_out?, qemu.kvm.cpu_out?' test_check: stap -p4 qemu_io.stp test_installcheck: stap qemu_io.stp -T 1
