RTE Tracepoint API
This file provides the tracepoint API to RTE applications.
Definition in file rte_trace_point.h.
#define RTE_TRACE_POINT_ARGS |
Macro to define the tracepoint arguments in RTE_TRACE_POINT macro.
Definition at line 42 of file rte_trace_point.h.
#define RTE_TRACE_POINT | ( | tp, | |
args, | |||
... | |||
) | __RTE_TRACE_POINT(generic, tp, args, __VA_ARGS__) |
Create a tracepoint.
A tracepoint is defined by specifying:
tp | Tracepoint object. Before using the tracepoint, an application needs to define the tracepoint using RTE_TRACE_POINT_REGISTER macro. |
args | C function style input arguments to define the arguments to tracepoint function. |
... | Define the payload of trace function. The payload will be formed using rte_trace_point_emit_* macros. Use ";" delimiter between two payloads. |
Definition at line 78 of file rte_trace_point.h.
#define RTE_TRACE_POINT_FP | ( | tp, | |
args, | |||
... | |||
) | __RTE_TRACE_POINT(fp, tp, args, __VA_ARGS__) |
Create a tracepoint for fast path.
Similar to RTE_TRACE_POINT, except that it is removed at compilation time unless the RTE_ENABLE_TRACE_FP configuration parameter is set.
tp | Tracepoint object. Before using the tracepoint, an application needs to define the tracepoint using RTE_TRACE_POINT_REGISTER macro. |

Definition at line 99 of file rte_trace_point.h.
#define RTE_TRACE_POINT_REGISTER | ( | trace, | |

Register a tracepoint.
