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 (Documentation/trace/histogram.rst)
136 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]keys = KEY1[, KEY2[...]]
139   if there is one histogram on the event.
141 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]values = VAL1[, VAL2[...]]
144 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]sort = SORT1[, SORT2[...]]
147 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]size = NR_ENTRIES
150 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]name = NAME
153 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]var.VARIABLE = EXPR
156 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]<pause|continue|clear>
159 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]onmatch.[M.]event = GROUP.EVENT
160   Set histogram 'onmatch' handler matching event parameter.
164 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]onmatch.[M.]trace = EVENT[, ARG1[...]]
166   EVENT must be a synthetic event name, and ARG1... are parameters
167   for that event. Mandatory if 'onmatch.event' option is set.
169 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]onmax.[M.]var = VAR
172 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]onchange.[M.]var = VAR
175 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]<onmax|onchange>.[M.]save = ARG1[, ARG2[...]]
180 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.[N.]<onmax|onchange>.[M.]snapshot
185 ftrace.[instance.INSTANCE.]event.GROUP.EVENT.hist.filter = FILTER_EXPR
188 Note that this 'hist' option can conflict with the per-event 'actions'
209 For example, to add filter and actions for each event, define kprobe
213   ftrace.event {
239                         event = initcall.initcall_start
261 The instance node also accepts event nodes so that each instance
262 can customize its event tracing.
271         event.kprobes {
