Name:mmio_print_map

Proto:static enum print_line_t mmio_print_map(struct trace_iterator *iter)

Type:enum print_line_t

Parameter:

TypeParameterName
struct trace_iterator *iter
214  entry = ent
217  s = The below is zeroed out in pipe_read
218  t = ns2usecs(ts)
219  usec_rem = do_div() is NOT a C function(t, USEC_PER_SEC)
220  secs = t
222  The trace_assign_type is a verifier that the entry type is* the same as the type being assigned. To add new types simply* add a line with the following format:* IF_ASSIGN(var, ent, type, id);* Where "type" is the trace type that includes the trace_entry(field, entry)
223  m = map
226  Case MMIO_PROBE or MMIO_UNPROBE == struct mmiotrace_map
227  race_seq_printf - sequence printing of trace information*@s: trace sequence descriptor*@fmt: printf format string* The tracer may use either sequence operations or its own* copy to user routines
232  Break
233  Case MMIO_PROBE or MMIO_UNPROBE == struct mmiotrace_map
234  race_seq_printf - sequence printing of trace information*@s: trace sequence descriptor*@fmt: printf format string* The tracer may use either sequence operations or its own* copy to user routines
237  Break
238  Default
239  race_seq_puts - trace sequence printing of simple string*@s: trace sequence descriptor*@str: simple string to record* The tracer may use either the sequence operations or its own* copy to user routines
240  Break
243  Return Several functions return TRACE_TYPE_PARTIAL_LINE if the trace_seq* overflowed, and TRACE_TYPE_HANDLED otherwise. This helper function* simplifies those functions and keeps them in sync.
