- u: only when the branch target is at the user level
- k: only when the branch target is in the kernel
- hv: only when the target is at the hypervisor level
+ - in_tx: only when the target is in a hardware transaction
+ - no_tx: only when the target is not in a hardware transaction
+ - abort_tx: only when the target is a hardware transaction abort

The option requires at least one branch type among any, any_call, any_ret, ind_call.
The various filters must be specified as a comma separated list: --branch-filter any_ret,u,k

--W::
