Events can optionally have a modifer by appending a colon and one or
more modifiers. Modifiers allow the user to restrict when events are
counted with 'u' for user-space, 'k' for kernel, 'h' for hypervisor.
+Additional modifiers are 'G' for guest counting (in KVM guests) and 'H'
+for host counting (not in KVM guests).
The 'p' modifier can be used for specifying how precise the instruction
address should be. The 'p' modifier is currently only implemented for
