PERF_BR_UNKNOWN anonymousenum PERF_BR_UNKNOWN: Common flow change classification
PERF_TXN_ELISION anonymousenum PERF_TXN_ELISION: Values for the memory transaction event qualifier, mostly for abort events. Multiple bits can be set.

perf_branch_sample_type_shift enum perf_branch_sample_type_shift: values to program into branch_sample_type when PERF_SAMPLE_BRANCH is set
perf_callchain_context enum perf_callchain_context
perf_event_ioc_flags enum perf_event_ioc_flags
perf_event_read_format enum perf_event_read_format: The format of the data returned by read() on a perf event fd, as specified by attr.read_format:
perf_event_sample_format enum perf_event_sample_format: Bits that can be set in attr.sample_type to request information in the overflow packets.
perf_event_type enum perf_event_type
perf_hw_cache_id enum perf_hw_cache_id: Generalized hardware cache events:
perf_hw_cache_op_id enum perf_hw_cache_op_id
perf_hw_cache_op_result_id enum perf_hw_cache_op_result_id
perf_hw_id enum perf_hw_id: Generalized performance event event_id types, used by the attr.event_id parameter of the sys_perf_event_open() syscall:
perf_sample_regs_abi enum perf_sample_regs_abi: Values to determine ABI of the registers dump.
perf_sw_ids enum perf_sw_ids: Special "software" events provided by the kernel, even if the hardware does not support performance events. These events measure various physical and sw events of the kernel (and allow the profiling of them as well):
