--------
These events are similar to tracepoint based events. Instead of Tracepoint,
this is based on kprobes (kprobe and kretprobe). So it can probe wherever
-kprobes can probe (this means, all functions body except for __kprobes
-functions). Unlike the Tracepoint based event, this can be added and removed
+kprobes can probe (this means, all functions except those with
+__kprobes/nokprobe_inline annotation and those marked NOKPROBE_SYMBOL).
+Unlike the Tracepoint based event, this can be added and removed
dynamically, on the fly.
To enable this feature, build your kernel with CONFIG_KPROBE_EVENTS=y.

+ * Variant of atomic_t specialized for reference counts.
+ *
+ * The interface matches the atomic_t interface (to aid in porting) but only
+ * provides the few functions one should use for reference counting.
+ *
+ * It differs in that the counter saturates at UINT_MAX and will not move once
+ * there. This avoids wrapping the counter and causing 'spurious'
+ * use-after-free issues.
+ *
+ * Memory ordering rules are slightly relaxed wrt regular atomic_t functions
+ * and provide only what is strictly required for refcounts.
+ *
+ * The increments are fully relaxed; these will not provide ordering. The
+ * rationale is that whatever is used to obtain the object we're increasing the
+ * reference count on will provide the ordering. For locked data structures,
+ * its the lock acquire, for RCU/lockless data structures its the dependent
+ * load.
+ *
+ * Do note that inc_not_zero() provides a control dependency which will order
+ * future stores against the inc, this ensures we'll never modify the object
+ * if we did not in fact acquire a reference.
+ *
+ * The decrements will provide release order, such that all the prior loads and
+ * stores will be issued before, it also provides a control dependency, which
+ * will order us against the subsequent free().
+ *
+ * The control dependency is against the load of the cmpxchg (ll/sc) that
+ * succeeded. This means the stores aren't fully ordered, but this is fine
+ * because the 1->0 transition indicates no concurrency.
+ *
+ * Note that the allocator is responsible for ordering things between free()
+ * and alloc().

SYNOPSIS
--------
[verse]
-'perf list' [--no-desc] [--long-desc] [hw|sw|cache|tracepoint|pmu|event_glob]
+'perf list' [--no-desc] [--long-desc] [hw|sw|cache|tracepoint|pmu|sdt|event_glob]
DESCRIPTION
-----------
--long-desc::
Print longer event descriptions.
+--details::
+Print how named events are resolved internally into perf events, and also
+any extra expressions computed by perf stat.
+
[[EVENT_MODIFIERS]]
EVENT MODIFIERS
. 'pmu' to print the kernel supplied PMU events.
+. 'sdt' to list all Statically Defined Tracepoint events.
+
. If none of the above is matched, it will apply the supplied glob to all
events, printing the ones that match.
displayed with the weight and local_weight sort keys. This currently works for TSX
abort events and some memory events in precise mode on modern Intel CPUs.
+--namespaces::
+Record events of type PERF_RECORD_NAMESPACES.
+
--transaction::
Record transaction flags for transaction related events.
--sort=::
Sort histogram entries by given key(s) - multiple keys can be specified
in CSV format. Following sort keys are available:
- pid, comm, dso, symbol, parent, cpu, socket, srcline, weight, local_weight.
+ pid, comm, dso, symbol, parent, cpu, socket, srcline, weight,
+ local_weight, cgroup_id.
Each key has following meaning:
- pid: command and tid of the task
- dso: name of library or module executed at the time of sample
- symbol: name of function executed at the time of sample
+ - symbol_size: size of function executed at the time of sample
- parent: name of function matched to the parent regex filter. Unmatched
entries are displayed as "[other]".
- cpu: cpu number the task ran at the time of sample
- weight: Event specific weight, e.g. memory latency or transaction
abort cost. This is the global weight.
- local_weight: Local weight version of the weight above.
+ - cgroup_id: ID derived from cgroup namespace device and inode numbers.
- transaction: Transaction abort flags.
- overhead: Overhead percentage of sample
- overhead_sys: Overhead percentage of sample running in system mode
By default, every sort keys not specified in -F will be appended
automatically.
+ If the keys starts with a prefix '+', then it will append the specified
+ field(s) to the default field order. For example: perf report -F +period,sample.
+
-p::
--parent=<regex>::
A regex filter to identify parent. The parent is a caller of this
sort_key can be:
- function: compare on functions (default)
- address: compare on individual code addresses
+ - srcline: compare on source filename and line number
branch can be:
- branch: include last branch information in callgraph when available.
--hierarchy::
Enable hierarchical output.
+--inline::
+ If a callgraph address belongs to an inlined function, the inline stack
+ will be printed. Each entry is function name or file/line.

--migrations::
Show migration events.
+-n::
+--next::
+ Show next task.
+
-I::
--idle-hist::
Show idle-related events only.
--fields::
Comma separated list of fields to print. Options are:
comm, tid, pid, time, cpu, event, trace, ip, sym, dso, addr, symoff,
- srcline, period, iregs, brstack, brstacksym, flags, bpf-output,
+ srcline, period, iregs, brstack, brstacksym, flags, bpf-output, brstackinsn,
callindent, insn, insnlen. Field list can be prepended with the type, trace, sw or hw,
to indicate to which event type the field list applies.
e.g., -F sw:comm,tid,time,ip,sym and -F trace:time,cpu,trace
i.e., -F "" is not allowed.
The brstack output includes branch related information with raw addresses using the
- /v/v/v/v/ syntax in the following order:
+ /v/v/v/v/cycles syntax in the following order:
FROM: branch source instruction
TO : branch target instruction
M/P/-: M=branch target mispredicted or branch direction was mispredicted, P=target predicted or direction predicted, -=not supported
X/- : X=branch inside a transactional region, -=not in transaction region or not supported
A/- : A=TSX abort entry, -=not aborted region or not supported
+ cycles
The brstacksym is identical to brstack, except that the FROM and TO addresses are printed in a symbolic form if possible.
+ When brstackinsn is specified the full assembler sequences of branch sequences for each sample
+ is printed. This is the full execution path leading to the sample. This is only supported when the
+ sample was recorded with perf record -b or -j any.
+
-k::
--vmlinux=<file>::
vmlinux pathname
--show-mmap-events
Display mmap related events (e.g. MMAP, MMAP2).
+--show-namespace-events
+ Display namespace events i.e. events of type PERF_RECORD_NAMESPACES.
+
--show-switch-events
Display context switch events i.e. events of type PERF_RECORD_SWITCH or
PERF_RECORD_SWITCH_CPU_WIDE.
stop time is not given (i.e, time string is 'x.y,') then analysis goes
to end of file.
+--max-blocks::
+ Set the maximum number of program blocks to print with brstackasm for
+ each sample.
