Lines Matching full:event

13 device initialization with full features of ftrace including per-event
37 Output trace-event data on printk buffer too.
66 (you can enable it by the "traceon" event trigger action)
81 ftrace.[instance.INSTANCE.]events = EVENT[, EVENT2[...]]
82 Enable given events on boot. You can use a wild card in EVENT.
94 Ftrace Per-Event Options
97 These options are setting per-event options.
99 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.enable
100 Enable GROUP:EVENT tracing.
102 ftrace.[instance.INSTANCE.]event.GROUP.enable
103 Enable all event tracing within GROUP.
105 ftrace.[instance.INSTANCE.]event.enable
106 Enable all event tracing.
108 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.filter = FILTER
109 Set FILTER rule to the GROUP:EVENT.
111 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.actions = ACTION[, ACTION2[...]]
112 Set ACTIONs to the GROUP:EVENT.
114 ftrace.[instance.INSTANCE.]event.kprobes.EVENT.probes = PROBE[, PROBE2[...]]
115 Defines new kprobe event based on PROBEs. It is able to define
116 multiple probes on one event, but those must have same type of
117 arguments. This option is available only for the event which
120 ftrace.[instance.INSTANCE.]event.synthetic.EVENT.fields = FIELD[, FIELD2[...]]
121 Defines new synthetic event with FIELDs. Each field should be
124 Note that kprobe and synthetic event definitions can be written under
126 take care for event name conflict.
131 Since it is too long to write a histogram action as a string for per-event
132 action option, there are tree-style options under per-event 'hist' subkey
134 please read the event histogram document [3]_.
138 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]keys = KEY1[, KEY2[...]]
141 if there is one histogram on the event.
143 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]values = VAL1[, VAL2[...]]
146 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]sort = SORT1[, SORT2[...]]
149 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]size = NR_ENTRIES
152 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]name = NAME
155 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]var.VARIABLE = EXPR
158 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]<pause|continue|clear>
161 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]onmatch.[M.]event = GROUP.EVENT
162 Set histogram 'onmatch' handler matching event parameter.
166 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]onmatch.[M.]trace = EVENT[, ARG1[...]]
168 EVENT must be a synthetic event name, and ARG1... are parameters
169 for that event. Mandatory if 'onmatch.event' option is set.
171 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]onmax.[M.]var = VAR
174 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]onchange.[M.]var = VAR
177 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]<onmax|onchange>.[M.]save = ARG1[, ARG2[...]]
182 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]<onmax|onchange>.[M.]snapshot
187 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.filter = FILTER_EXPR
190 Note that this 'hist' option can conflict with the per-event 'actions'
211 For example, to add filter and actions for each event, define kprobe
215 ftrace.event {
241 event = initcall.initcall_start
263 The instance node also accepts event nodes so that each instance
264 can customize its event tracing.
273 event.kprobes {
