- any_call: any function call or system call
- any_ret: any function return or system call return
- ind_call: any indirect branch
+ - ind_jmp: any indirect jump
- call: direct calls, including far (to/from kernel) calls
- u: only when the branch target is at the user level
- k: only when the branch target is in the kernel
- no_tx: only when the target is not in a hardware transaction
- abort_tx: only when the target is a hardware transaction abort
- cond: conditional branches
+ - call_stack: save call stack
+ - no_flags: don't save branch flags e.g prediction, misprediction etc
+ - no_cycles: don't save branch cycles
+ - hw_index: save branch hardware index
- save_type: save branch type during sampling in case binary is not available later
For the platforms with Intel Arch LBR support (12th-Gen+ client or
4th-Gen Xeon+ server), the save branch type is unconditionally enabled
