-NAME
-----
-perf-help - display help information about perf
-
-SYNOPSIS
---------
-'perf help' [-a|--all] [COMMAND]
-
-DESCRIPTION
------------
-
-With no options and no COMMAND given, the synopsis of the 'perf'
-command and a list of the most commonly used perf commands are printed
-on the standard output.
-
-If the option '--all' or '-a' is given, then all available commands are
-printed on the standard output.
-
-If a perf command is named, a manual page for that command is brought
-up. The 'man' program is used by default for this purpose, but this
-can be overridden by other options or configuration variables.
-
-Note that `perf --help ...` is identical to `perf help ...` because the
-former is internally converted into the latter.
-
-OPTIONS
--------
--a::
---all::
-	Prints all the available commands on the standard output. This
-	option supersedes any other option.

-Performance Counters for Linux
-------------------------------
-
-Performance counters are special hardware registers available on most modern
-CPUs. These registers count the number of certain types of hw events: such
-as instructions executed, cachemisses suffered, or branches mis-predicted -
-without slowing down the kernel or applications. These registers can also
-trigger interrupts when a threshold number of events have passed - and can
-thus be used to profile the code that runs on that CPU.
-
-The Linux Performance Counter subsystem provides an abstraction of these
-hardware capabilities. It provides per task and per CPU counters, counter
-groups, and it provides event capabilities on top of those.  It
-provides "virtual" 64-bit counters, regardless of the width of the
-underlying hardware counters.
-
-Performance counters are accessed via special file descriptors.
-There's one file descriptor per virtual counter used.
-
-The special file descriptor is opened via the perf_counter_open()
-system call:
-
-   int sys_perf_counter_open(struct perf_counter_hw_event *hw_event_uptr,
-			     pid_t pid, int cpu, int group_fd,
-			     unsigned long flags);
-
-The syscall returns the new fd. The fd can be used via the normal
-VFS system calls: read() can be used to read the counter, fcntl()
-can be used to set the blocking mode, etc.
-
-Multiple counters can be kept open at a time, and the counters
-can be poll()ed.
-
-When creating a new counter fd, 'perf_counter_hw_event' is:
-
-struct perf_counter_hw_event {
-        /*
-         * The MSB of the config word signifies if the rest contains cpu
-         * specific (raw) counter configuration data, if unset, the next
-         * 7 bits are an event type and the rest of the bits are the event
-         * identifier.
-         */
-        __u64                   config;
-
-        __u64                   irq_period;
-        __u32                   record_type;

-The 'config' field specifies what the counter should count.  It
-is divided into 3 bit-fields:
-
-raw_type: 1 bit   (most significant bit)	0x8000_0000_0000_0000
-type:	  7 bits  (next most significant)	0x7f00_0000_0000_0000
-event_id: 56 bits (least significant)		0x00ff_ffff_ffff_ffff
-
-If 'raw_type' is 1, then the counter will count a hardware event
-specified by the remaining 63 bits of event_config.  The encoding is
-machine-specific.
-
-If 'raw_type' is 0, then the 'type' field says what kind of counter
-this is, with the following encoding:
-
-enum perf_event_types {
-	PERF_TYPE_HARDWARE		= 0,
-	PERF_TYPE_SOFTWARE		= 1,
-	PERF_TYPE_TRACEPOINT		= 2,
-};
-
-A counter of PERF_TYPE_HARDWARE will count the hardware event
-specified by 'event_id':
-
-/*
- * Generalized performance counter event types, used by the hw_event.event_id
- * parameter of the sys_perf_counter_open() syscall:
- */
-enum hw_event_ids {
-	/*
-	 * Common hardware events, generalized by the kernel:

-	PERF_COUNT_BRANCH_INSTRUCTIONS	= 4,
-	PERF_COUNT_BRANCH_MISSES	= 5,
-	PERF_COUNT_BUS_CYCLES		= 6,
-};
-
-These are standardized types of events that work relatively uniformly
-on all CPUs that implement Performance Counters support under Linux,
-although there may be variations (e.g., different CPUs might count
-cache references and misses at different levels of the cache hierarchy).
-If a CPU is not able to count the selected event, then the system call
-will return -EINVAL.
-
-More hw_event_types are supported as well, but they are CPU-specific
-and accessed as raw events.  For example, to count "External bus
-cycles while bus lock signal asserted" events on Intel Core CPUs, pass
-in a 0x4064 event_id value and set hw_event.raw_type to 1.
-
-A counter of type PERF_TYPE_SOFTWARE will count one of the available
-software events, selected by 'event_id':
-
-/*
- * Special "software" counters provided by the kernel, even if the hardware
- * does not support performance counters. These counters measure various
- * physical and sw events of the kernel (and allow the profiling of them as
- * well):

-	PERF_COUNT_PAGE_FAULTS_MAJ	= 6,
-};
-
-Counters of the type PERF_TYPE_TRACEPOINT are available when the ftrace event
-tracer is available, and event_id values can be obtained from
-/debug/tracing/events/*/*/id
-
-
-Counters come in two flavours: counting counters and sampling
-counters.  A "counting" counter is one that is used for counting the
-number of events that occur, and is characterised by having
-irq_period = 0.
-
-
-A read() on a counter returns the current value of the counter and possible
-additional values as specified by 'read_format', each value is a u64 (8 bytes)
-in size.
-
-/*
- * Bits that can be set in hw_event.read_format to request that
- * reads on the counter should return the indicated quantities,
- * in increasing order of bit value, after the counter value.
- */
-enum perf_counter_read_format {
-        PERF_FORMAT_TOTAL_TIME_ENABLED  =  1,
-        PERF_FORMAT_TOTAL_TIME_RUNNING  =  2,
-};
-
-Using these additional values one can establish the overcommit ratio for a
-particular counter allowing one to take the round-robin scheduling effect
-into account.
-
-
-A "sampling" counter is one that is set up to generate an interrupt
-every N events, where N is given by 'irq_period'.  A sampling counter
-has irq_period > 0. The record_type controls what data is recorded on each
-interrupt:
-
-/*
- * Bits that can be set in hw_event.record_type to request information
- * in the overflow packets.
- */
-enum perf_counter_record_format {
-        PERF_RECORD_IP          = 1U << 0,
-        PERF_RECORD_TID         = 1U << 1,
-        PERF_RECORD_TIME        = 1U << 2,
-        PERF_RECORD_ADDR        = 1U << 3,
-        PERF_RECORD_GROUP       = 1U << 4,
-        PERF_RECORD_CALLCHAIN   = 1U << 5,
-};
-
-Such (and other) events will be recorded in a ring-buffer, which is
-available to user-space using mmap() (see below).
-
-The 'disabled' bit specifies whether the counter starts out disabled
-or enabled.  If it is initially disabled, it can be enabled by ioctl
-or prctl (see below).
-
-The 'inherit' bit, if set, specifies that this counter should count
-events on descendant tasks as well as the task specified.  This only
-applies to new descendents, not to any existing descendents at the
-time the counter is created (nor to any new descendents of existing
-descendents).
-
-The 'pinned' bit, if set, specifies that the counter should always be
-on the CPU if at all possible.  It only applies to hardware counters
-and only to group leaders.  If a pinned counter cannot be put onto the
-CPU (e.g. because there are not enough hardware counters or because of
-a conflict with some other event), then the counter goes into an
-'error' state, where reads return end-of-file (i.e. read() returns 0)
-until the counter is subsequently enabled or disabled.
-
-The 'exclusive' bit, if set, specifies that when this counter's group
-is on the CPU, it should be the only group using the CPU's counters.
-In future, this will allow sophisticated monitoring programs to supply
-extra configuration information via 'extra_config_len' to exploit
-advanced features of the CPU's Performance Monitor Unit (PMU) that are
-not otherwise accessible and that might disrupt other hardware
-counters.
-
-The 'exclude_user', 'exclude_kernel' and 'exclude_hv' bits provide a
-way to request that counting of events be restricted to times when the
-CPU is in user, kernel and/or hypervisor mode.
-
-The 'mmap' and 'munmap' bits allow recording of PROT_EXEC mmap/munmap
-operations, these can be used to relate userspace IP addresses to actual
-code, even after the mapping (or even the whole process) is gone,
-these events are recorded in the ring-buffer (see below).
-
-The 'comm' bit allows tracking of process comm data on process creation.
-This too is recorded in the ring-buffer (see below).
-
-The 'pid' parameter to the perf_counter_open() system call allows the
-counter to be specific to a task:
-
- pid == 0: if the pid parameter is zero, the counter is attached to the
- current task.
-
- pid > 0: the counter is attached to a specific task (if the current task
- has sufficient privilege to do so)
-
- pid < 0: all tasks are counted (per cpu counters)
-
-The 'cpu' parameter allows a counter to be made specific to a CPU:
-
- cpu >= 0: the counter is restricted to a specific CPU
- cpu == -1: the counter counts on all CPUs
-
-(Note: the combination of 'pid == -1' and 'cpu == -1' is not valid.)
-
-A 'pid > 0' and 'cpu == -1' counter is a per task counter that counts
-events of that task and 'follows' that task to whatever CPU the task
-gets schedule to. Per task counters can be created by any user, for
-their own tasks.
-
-A 'pid == -1' and 'cpu == x' counter is a per CPU counter that counts
-all events on CPU-x. Per CPU counters need CAP_SYS_ADMIN privilege.
-
-The 'flags' parameter is currently unused and must be zero.
-
-The 'group_fd' parameter allows counter "groups" to be set up.  A
-counter group has one counter which is the group "leader".  The leader
-is created first, with group_fd = -1 in the perf_counter_open call
-that creates it.  The rest of the group members are created
-subsequently, with group_fd giving the fd of the group leader.
-(A single counter on its own is created with group_fd = -1 and is
-considered to be a group with only 1 member.)
-
-A counter group is scheduled onto the CPU as a unit, that is, it will
-only be put onto the CPU if all of the counters in the group can be
-put onto the CPU.  This means that the values of the member counters
-can be meaningfully compared, added, divided (to get ratios), etc.,
-with each other, since they have counted events for the same set of
-executed instructions.
-
-
-Like stated, asynchronous events, like counter overflow or PROT_EXEC mmap
-tracking are logged into a ring-buffer. This ring-buffer is created and
-accessed through mmap().
-
-The mmap size should be 1+2^n pages, where the first page is a meta-data page
-(struct perf_counter_mmap_page) that contains various bits of information such
-as where the ring-buffer head is.
-
-/*

-Notification of new events is possible through poll()/select()/epoll() and

-so many counter overflow events.
-
-Future work will include a splice() interface to the ring-buffer.
-
-
-Counters can be enabled and disabled in two ways: via ioctl and via
-prctl.  When a counter is disabled, it doesn't count or generate
-events but does continue to exist and maintain its count value.
-
-An individual counter or counter group can be enabled with
-
-	ioctl(fd, PERF_COUNTER_IOC_ENABLE);
-
-or disabled with
-
-	ioctl(fd, PERF_COUNTER_IOC_DISABLE);
-
-Enabling or disabling the leader of a group enables or disables the
-whole group; that is, while the group leader is disabled, none of the
-counters in the group will count.  Enabling or disabling a member of a
-group other than the leader only affects that counter - disabling an
-non-leader stops that counter from counting but doesn't affect any
-other counter.
-
-Additionally, non-inherited overflow counters can use
-
-	ioctl(fd, PERF_COUNTER_IOC_REFRESH, nr);
-
-to enable a counter for 'nr' events, after which it gets disabled again.
-
-A process can enable or disable all the counter groups that are
-attached to it, using prctl:
-
-	prctl(PR_TASK_PERF_COUNTERS_ENABLE);
-
-	prctl(PR_TASK_PERF_COUNTERS_DISABLE);
-
-This applies to all counters on the current process, whether created
-by this process or by another, and doesn't affect any counters that
-this process has created on other processes.  It only enables or
-disables the group leaders, not any other members in the groups.

- * This function implements the Damerau-Levenshtein algorithm to
- * calculate a distance between strings.
- *
- * Basically, it says how many letters need to be swapped, substituted,
- * deleted from, or added to string1, at least, to get string2.
- *
- * The idea is to build a distance matrix for the substrings of both
- * strings.  To avoid a large space complexity, only the last three rows
- * are kept in memory (if swaps had the same or higher cost as one deletion
- * plus one insertion, only two rows would be needed).
- *
- * At any stage, "i + 1" denotes the length of the current substring of
- * string1 that the distance is calculated for.
- *
- * row2 holds the current row, row1 the previous row (i.e. for the substring
- * of string1 of length "i"), and row0 the row before that.
- *
- * In other words, at the start of the big loop, row2[j + 1] contains the
- * Damerau-Levenshtein distance between the substring of string1 of length
- * "i" and the substring of string2 of length "j + 1".
- *
- * All the big loop does is determine the partial minimum-cost paths.
- *
- * It does so by calculating the costs of the path ending in characters
- * i (in string1) and j (in string2), respectively, given that the last
- * operation is a substition, a swap, a deletion, or an insertion.
- *
- * This implementation allows the costs to be weighted:
- *
- * - w (as in "sWap")
- * - s (as in "Substitution")
- * - a (for insertion, AKA "Add")
- * - d (as in "Deletion")
- *
- * Note that this algorithm calculates a distance _iff_ d == a.

-
-  To use rbtrees you'll have to implement your own insert and search cores.
-  This will avoid us to use callbacks and to drop drammatically performances.
-  I know it's not the cleaner way,  but in C (not in C++) to get
-  performances and genericity...
-
-  Some example of insert and search follows here. The search is a plain
-  normal search over an ordered tree. The insert instead must be implemented
-  int two steps: as first thing the code must insert the element in
-  order as a red leaf in the tree, then the support library function
-  rb_insert_color() must be called. Such function will do the
-  not trivial work to rebalance the rbtree if necessary.

-/*
- * Strbuf's can be use in many ways: as a byte array, or to store arbitrary
- * long, overflow safe strings.
- *
- * Strbufs has some invariants that are very important to keep in mind:
- *
- * 1. the ->buf member is always malloc-ed, hence strbuf's can be used to
- *    build complex strings/buffers whose final size isn't easily known.
- *
- *    It is NOT legal to copy the ->buf pointer away.
- *    `strbuf_detach' is the operation that detachs a buffer from its shell
- *    while keeping the shell valid wrt its invariants.
- *
- * 2. the ->buf member is a byte array that has at least ->len + 1 bytes
- *    allocated. The extra byte is used to store a '\0', allowing the ->buf
- *    member to be a valid C-string. Every strbuf function ensure this
- *    invariant is preserved.
- *
- *    Note that it is OK to "play" with the buffer directly if you work it
- *    that way:
- *
- *    strbuf_grow(sb, SOME_SIZE);
- *       ... Here, the memory array starting at sb->buf, and of length
- *       ... strbuf_avail(sb) is all yours, and you are sure that
- *       ... strbuf_avail(sb) is at least SOME_SIZE.
- *    strbuf_setlen(sb, sb->len + SOME_OTHER_SIZE);
- *
- *    Of course, SOME_OTHER_SIZE must be smaller or equal to strbuf_avail(sb).
- *
- *    Doing so is safe, though if it has to be done in many places, adding the
- *    missing API to the strbuf module is the way to go.
- *
- *    XXX: do _not_ assume that the area that is yours is of size ->alloc - 1
- *         even if it's true in the current implementation. Alloc is somehow a
- *         "private" member that should not be messed with.
