+ * be defined by Linux. They are used as a jump table by the CPU when a
+ * given vector is triggered - by a CPU-external, CPU-internal or
+ * software-triggered event.
+ *
+ * Linux sets the kernel code address each entry jumps to early during
+ * bootup, and never changes them. This is the general layout of the
+ * IDT entries:
+ *
+ * Vectors 0 ... 31 : system traps and exceptions - hardcoded events
+ * Vectors 32 ... 127 : device interrupts
+ * Vector 128 : legacy int80 syscall interface
+ * Vectors 129 ... LOCAL_TIMER_VECTOR-1
+ * Vectors LOCAL_TIMER_VECTOR ... 255 : special interrupts
+ *
+ * 64-bit x86 has per CPU IDT tables, 32-bit has one shared IDT table.

Print how named events are resolved internally into perf events, and also
any extra expressions computed by perf stat.
+--deprecated::
+Print deprecated events. By default the deprecated events are hidden.
+
[[EVENT_MODIFIERS]]
EVENT MODIFIERS
---------------
Users who wants to get the actual value can apply --no-metric-only.
+--all-kernel::
+Configure all used events to run in kernel space.
+
+--all-user::
+Configure all used events to run in user space.
+
EXAMPLES
--------
Show all syscalls followed by a summary by thread with min, max, and
average times (in msec) and relative stddev.
+--errno-summary::
+ To be used with -s or -S, to show stats for the errnos experienced by
+ syscalls, using only this option will trigger --summary.
+
--tool_stats::
Show tool stats such as number of times fd->pathname was discovered thru
hooking the open syscall return + vfs_getname or via reading /proc/pid/fd, etc.
