markers: auto enable tracepoints (new API : trace_mark_tp()) 2008-11-16T08:01:29+00:00 Mathieu Desnoyers mathieu.desnoyers@polymtl.ca 2008-11-14T22:47:39+00:00 c1df1bd2c4d4b20c83755a0f41956b57aec4842a Impact: new API Add a new API trace_mark_tp(), which declares a marker within a tracepoint probe. When the marker is activated, the tracepoint is automatically enabled. No branch test is used at the marker site, because it would be a duplicate of the branch already present in the tracepoint.

Impact: new API

Add a new API trace_mark_tp(), which declares a marker within a
tracepoint probe. When the marker is activated, the tracepoint is
automatically enabled.

No branch test is used at the marker site, because it would be a
duplicate of the branch already present in the tracepoint.
