Merge tag 'perf-tools-for-v6.2-1-2022-12-16' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools updates from Arnaldo Carvalho de Melo:
 "Libraries:

   - Drop the old copy of libtraceevent in tools/lib/traceevent/ now
     that all major distros ship it from its external repository.

     This is now just another feature detection, emitting a warning when
     the libtraceevent-dev[el] package isn't installed, disabling the
     build of perf features and tools that strictly require parsing
     things from tracefs while keeping the core functionality present
     and working with a subset of the events, the most used ones like
     CPU cycles, hardware cache and also vendor events, etc.

     This was tested with lots of containers for Fedora, Debian,
     OpenSUSE, Alpine Linux, Ubuntu, with cross builds, etc.

  Build:

   - Update to C standard to gnu11, like was done for the kernel.

   - Install the tools/lib/ libraries locally instead of having headers
     searched directly from the source code directories, to help the
     cases where we can build either from in-kernel source libraries or
     from the same library shipped as a distro package, as is the case
     with libbpf and was the case with libtraceevent.

  perf stat:

   - Do not delay the workload with --delay, the delay is just for
     starting to count the events, to skip noise at workload startup.

   - When we have events for each cgroup, the metric should be printed
     for each cgroup separately.

        $ perf stat -a --for-each-cgroup system.slice,user.slice --metric-only sleep 1

        Performance counter stats for 'system wide':

                        GHz  insn per cycle  branch-misses of all branches
        system.slice  3.792      0.61                  3.24%
        user.slice    3.661      2.32                  0.37%

   - Fix printing field separator in CSV metrics output.

   - Fix --metric-only --json output.

   - Fix summary output in CSV with --metric-only.

   - Update event group check for support of uncore event.

  perf test:

   - Stop requiring a C toolchain in shell tests, instead add a workload
     option that has all the previously C snippets built as part of
     'perf test -w' that then get used in the 'perf test' shell scripts.

   - Add event group test for events in multiple PMUs

   - The "kernel lock contention analysis" test should not print
     warnings in quiet mode.

   - Add attr tests for ARM64's new VG register.

   - Fix record test on KVM guests, as using precise flag with the
     br_inst_retired.near_call event causes the test fail on KVM guests,
     even when the guests have PMU forwarding enabled and the event
     itself is supported, so just remove the precise flag from the
     event.

   - Add mechanism for skipping attr tests on specific kernel versions
     where it is known that these checks will fail.

   - Skip watchpoint tests if no watchpoints available.

   - Add more Intel PT 'perf test' entries: hybrid CPUs, split the
     packet decoder into a suite of subtests.

  perf script:

   - Introduce task analyzer python script, where one first records some events:

     Recording can be done in two ways:

        $ perf script record tasks-analyzer -- sleep 10
        $ perf record -e sched:sched_switch -a -- sleep 10

     The script can parse any perf.data files, as long as it has
     sched:sched_switch events, other events will be ignored.

     The most simple report use case is to just call the script without
     arguments.

     Runtime is the time the task was running on the CPU, Time Out-In is
     the time between the process being scheduled *out* and scheduled
     back *in*. So the last time span between two executions:

        $ perf script report tasks-analyzer
            Switched-In     Switched-Out CPU    PID    TID             Comm  Runtime  Time Out-In

        [...]

  perf lock:

   - Allow concurrent record and report to support live monitoring of
     kernel lock contention without BPF:

        # perf lock record -a -o- sleep 1 | perf lock contention -i-
         contended   total wait     max wait     avg wait         type   caller

   - Implement -t/--threads option when using BPF:

        $ sudo ./perf lock contention -abt -E 5 sleep 1
         contended  total wait   max wait   avg wait      pid  comm

   - Add -l/--lock-addr to aggregate per-lock-instance contention:

        $ sudo ./perf lock contention -abl sleep 1
         contended  total wait  max wait  avg wait           address  symbol

  perf record:

   - Add remaining branch filters: "no_cycles", "no_flags" & "hw_index",
     to be used with hardware such as Intel's LBR that allows things
     like stitching stacks of two samples to overcome the limits of the
     number of LBR registers.

  Symbol resolution:

   - Handle .debug files created with 'objcopy --only-keep-debug', where
     program headers are zeroed and thus can't be used for adjustments,
     use the info in the runtime_ss (runtime ELF) instead.

  perf trace:

   - Add BPF based augmenter for the 'perf_event_open's 'struct
     perf_event_attr' argument.

   - Add BPF based augmenter for the 'clock_gettime's 'struct timespec'
     argument.

   - In both cases the syscall tracepoint has just the pointer value, we
     need to hook a BPF program to collect the pointer contents, and
     then, in userspace, pretty print it in 'perf trace'.

  perf list:

   - Introduce JSON output of events.

   - Streamline how the expression specifying what events should be
     shown is handled, fixing several corner cases, such as the metric
     filter that is specified as a glob but was using strstr().

  perf probe:

   - Fix to avoid crashing if DW_AT_decl_file is NULL, coping with clang
     generating DWARF5 like that.

   - Use dwarf_attr_integrate() as generic DWARF attr accessor as it
     supersedes dwarf_attr(), supporting abstact origin DIEs.

  perf inject:

   - Set PERF_RECORD_MISC_BUILD_ID_SIZE in the PERF_RECORD_HEADER_BUILD_ID
     so that perf.data readers can get the real build-id size and avoid
     trailing zeroes.

  perf data:

   - Add tracepoint fields when converting a perf.data file to JSON.

  arm64:

   - Fix mksyscalltbl, don't lose syscalls due to sort -nu.

   - Add Arm Neoverse V2 PMU events.

  riscv:

   - Add riscv sbi firmware std event files.

   - Add Sifive U74 vendor events (JSON) file.

   - Add some more events and metrics for Alderlake/Alderlake-N.

  Documentation:

   - Add data documentation for the PMU structs in the C source code.

  Miscellaneous:

   - Periodic sanitization of headers, adding missing includes, removing
     needless ones, creating new ones, etc.

   - Use sig_atomic_t for signal handlers to avoid undefined behaviour
     in all perf tools.

   - Fixes for libbpf 1.0+ compatibility (maps, etc) on 'perf trace' BPF
     examples.

   - Remove some old perf bpf examples, leave the best ones that
     demonstrate how to associate BPF functions to points in the kernel.

   - Make quiet mode consistent between tools.

   - Use dedicated non-atomic clear/set bit helpers.

   - Use "grep -E" instead of "egrep" as recommended by warning emitted
     by GNU grep since at least version 3.8.

   - Complete list of supported subcommands in the 'perf daemon' help
     message.

   - Update John Garry's email address for arm64 perf tooling on the
     MAINTAINERS file, he moved from Huawei to Oracle"

-DESCRIPTION
------------
-These functions can be used to handle the mapping between pid and process name.
-The library builds a cache of these mappings, which is used to display the name
-of the process, instead of its pid. This information can be retrieved from
-tracefs/saved_cmdlines file.
-
-The _tep_register_comm()_ function registers a _pid_ / process name mapping.
-If a command with the same _pid_ is already registered, an error is returned.
-The _pid_ argument is the process ID, the _comm_ argument is the process name,
-_tep_ is the event context. The _comm_ is duplicated internally.
-
-The _tep_override_comm()_ function registers a _pid_ / process name mapping.
-If a process with the same pid is already registered, the process name string is
-udapted with the new one. The _pid_ argument is the process ID, the _comm_
-argument is the process name, _tep_ is the event context. The _comm_ is
-duplicated internally.
-
-The _tep_is_pid_registered()_ function checks if a pid has a process name
-mapping registered. The _pid_ argument is the process ID, _tep_ is the event
-context.
-
-The _tep_data_comm_from_pid()_ function returns the process name for a given
-pid. The _pid_ argument is the process ID, _tep_ is the event context.
-The returned string should not be freed, but will be freed when the _tep_
-handler is closed.
-
-The _tep_data_pid_from_comm()_ function returns a pid for a given process name.
-The _comm_ argument is the process name, _tep_ is the event context.
-The argument _next_ is the cmdline structure to search for the next pid.
-As there may be more than one pid for a given process, the result of this call
-can be passed back into a recurring call in the _next_ parameter, to search for
-the next pid. If _next_ is NULL, it will return the first pid associated with
-the _comm_. The function performs a linear search, so it may be slow.
-
-The _tep_cmdline_pid()_ function returns the pid associated with a given
-_cmdline_. The _tep_ argument is the event context.
-
-RETURN VALUE
-------------
-_tep_register_comm()_ function returns 0 on success. In case of an error -1 is
-returned and errno is set to indicate the cause of the problem: ENOMEM, if there
-is not enough memory to duplicate the _comm_ or EEXIST if a mapping for this
-_pid_ is already registered.
-
-_tep_override_comm()_ function returns 0 on success. In case of an error -1 is
-returned and errno is set to indicate the cause of the problem: ENOMEM, if there
-is not enough memory to duplicate the _comm_.

-_tep_is_pid_registered()_ function returns true if the _pid_ has a process name
-mapped to it, false otherwise.
-
-_tep_data_comm_from_pid()_ function returns the process name as string, or the
-string "<...>" if there is no mapping for the given pid.
-
-_tep_data_pid_from_comm()_ function returns a pointer to a struct cmdline, that
-holds a pid for a given process, or NULL if none is found. This result can be
-passed back into a recurring call as the _next_ parameter of the function.
-
-_tep_cmdline_pid()_ functions returns the pid for the give cmdline. If _cmdline_
- is NULL, then -1 is returned.
-
-EXAMPLE
--------
-The following example registers pid for command "ls", in context of event _tep_
-and performs various searches for pid / process name mappings:
-[source,c]
---
-#include <event-parse.h>
-...
-int ret;
-int ls_pid = 1021;
-struct tep_handle *tep = tep_alloc();
-...
-	ret = tep_register_comm(tep, "ls", ls_pid);
-	if (ret != 0 && errno == EEXIST)
-		ret = tep_override_comm(tep, "ls", ls_pid);
-	if (ret != 0) {
-		/* Failed to register pid / command mapping */
-	}
-...
-	if (tep_is_pid_registered(tep, ls_pid) == 0) {
-		/* Command mapping for ls_pid is not registered */
-	}
-...
-	const char *comm = tep_data_comm_from_pid(tep, ls_pid);
-	if (comm) {
-		/* Found process name for ls_pid */
-	}
-...
-	int pid;
-	struct cmdline *cmd = tep_data_pid_from_comm(tep, "ls", NULL);
-	while (cmd) {
-		pid = tep_cmdline_pid(tep, cmd);

---
-
-DESCRIPTION
------------
-The _tep_list_events()_ function returns an array of pointers to the events,
-sorted by the _sort_type_ criteria. The last element of the array is NULL.
-The returned memory must not be freed, it is managed by the library.
-The function is not thread safe. The _tep_ argument is trace event parser
-context. The _sort_type_ argument is the required sort criteria:
-[verse]
---
-	_TEP_EVENT_SORT_ID_	- sort by the event ID.
-	_TEP_EVENT_SORT_NAME_	- sort by the event (name, system, id) triplet.
-	_TEP_EVENT_SORT_SYSTEM_	- sort by the event (system, name, id) triplet.
---
-
-The _tep_list_events_copy()_ is a thread safe version of _tep_list_events()_.
-It has the same behavior, but the returned array is allocated internally and
-must be freed by the caller. Note that the content of the array must not be
-freed (see the EXAMPLE below).
-
-RETURN VALUE
-------------
-The _tep_list_events()_ function returns an array of pointers to events.
-In case of an error, NULL is returned. The returned array must not be freed,
-it is managed by the library.
-
-The _tep_list_events_copy()_ function returns an array of pointers to events.
-In case of an error, NULL is returned. The returned array must be freed by
-the caller.

-NAME
-----
-tep_print_event - Writes event information into a trace sequence.

-SYNOPSIS
---------
-[verse]
---
-*#include <event-parse.h>*
-*#include <trace-seq.h>*
-
-void *tep_print_event*(struct tep_handle pass:[*]_tep_, struct trace_seqpass:[*]_s_, struct tep_record pass:[*]_record_, const char pass:[*]_fmt_, _..._)
---
-
-DESCRIPTION
------------
-
-The _tep_print_event()_ function parses the event information of the given
-_record_ and writes it into the trace sequence _s_, according to the format
-string _fmt_. The desired information is specified after the format string.
-The _fmt_ is printf-like format string, following arguments are supported:
-[verse]
---
-	TEP_PRINT_PID, "%d"  - PID of the event.
-	TEP_PRINT_CPU, "%d"  - Event CPU.
-	TEP_PRINT_COMM, "%s" - Event command string.
-	TEP_PRINT_NAME, "%s" - Event name.
-	TEP_PRINT_LATENCY, "%s" - Latency of the event. It prints 4 or more
-			fields - interrupt state, scheduling state,
-			current context, and preemption count.
-			Field 1 is the interrupt enabled state:
-				d : Interrupts are disabled
-				. : Interrupts are enabled
-				X : The architecture does not support this
-				    information
-			Field 2 is the "need resched" state.
-				N : The task is set to call the scheduler when
-				    possible, as another higher priority task
-				    may need to be scheduled in.
-				. : The task is not set to call the scheduler.
-			Field 3 is the context state.
-				. : Normal context
-				s : Soft interrupt context
-				h : Hard interrupt context
-				H : Hard interrupt context which triggered
-				    during soft interrupt context.
-				z : NMI context
-				Z : NMI context which triggered during hard
-				    interrupt context
-			Field 4 is the preemption count.
-				. : The preempt count is zero.
-			On preemptible kernels (where the task can be scheduled
-			out in arbitrary locations while in kernel context), the
-			preempt count, when non zero, will prevent the kernel
-			from scheduling out the current task. The preempt count
-			number is displayed when it is not zero.
-			Depending on the kernel, it may show other fields
-			(lock depth, or migration disabled, which are unique to
-			specialized kernels).
-	TEP_PRINT_TIME, %d - event time stamp. A divisor and precision can be
-			specified as part of this format string:
-			"%precision.divisord". Example:
-			"%3.1000d" - divide the time by 1000 and print the first
-			3 digits before the dot. Thus, the time stamp
-			"123456000" will be printed as "123.456"
-	TEP_PRINT_INFO, "%s" - event information.
-	TEP_PRINT_INFO_RAW, "%s" - event information, in raw format.

-DESCRIPTION
------------
-These functions can be used to find a field and retrieve its value.
-
-The _tep_get_any_field_val()_ function searches in the _record_ for a field
-with _name_, part of the _event_. If the field is found, its value is stored in
-_val_. If there is an error and _err_ is not zero, then an error string is
-written into _s_.
-
-The _tep_get_common_field_val()_ function does the same as
-_tep_get_any_field_val()_, but searches only in the common fields. This works
-for any event as all events include the common fields.
-
-The _tep_get_field_val()_ function does the same as _tep_get_any_field_val()_,
-but searches only in the event specific fields.
-
-The _tep_get_field_raw()_ function searches in the _record_ for a field with
-_name_, part of the _event_. If the field is found, a pointer to where the field
-exists in the record's raw data is returned. The size of the data is stored in
-_len_. If there is an error and _err_ is not zero, then an error string is
-written into _s_.
-
-RETURN VALUE
-------------
-The _tep_get_any_field_val()_, _tep_get_common_field_val()_ and
-_tep_get_field_val()_ functions return 0 on success, or -1 in case of an error.
-
-The _tep_get_field_raw()_ function returns a pointer to field's raw data, and
-places the length of this data in _len_. In case of an error NULL is returned.
-
-EXAMPLE
--------
-[source,c]
---
-#include <event-parse.h>
-#include <trace-seq.h>
-...
-struct tep_handle *tep = tep_alloc();

-void process_record(struct tep_record *record)
-{
-	int len;
-	char *comm;
-	struct tep_event_format *event;
-	unsigned long long val;
-
-	event = tep_find_event_by_record(pevent, record);
-	if (event != NULL) {
-		if (tep_get_common_field_val(NULL, event, "common_type",
-					     record, &val, 0) == 0) {
-			/* Got the value of common type field */
-		}
-		if (tep_get_field_val(NULL, event, "pid", record, &val, 0) == 0) {
-			/* Got the value of pid specific field */

-
-void *tep_print_field*(struct trace_seq pass:[*]_s_, void pass:[*]_data_, struct tep_format_field pass:[*]_field_);

---
-
-DESCRIPTION
------------
-These functions print recorded field's data, according to the field's type.
-
-The _tep_print_field()_ function extracts from the recorded raw _data_ value of
-the _field_ and prints it into _s_, according to the field type.
-
-The _tep_print_fields()_ prints each field name followed by the record's field
-value according to the field's type:
-[verse]
---
-"field1_name=field1_value field2_name=field2_value ..."
---
-It iterates all fields of the _event_, and calls _tep_print_field()_ for each of
-them.
-
-The _tep_print_num_field()_ function prints a numeric field with given format
-string. A search is performed in the _event_ for a field with _name_. If such
-field is found, its value is extracted from the _record_ and is printed in the
-_s_, according to the given format string _fmt_. If the argument _err_ is
-non-zero, and an error occures - it is printed in the _s_.
-
-The _tep_print_func_field()_ function prints a function field with given format
-string.  A search is performed in the _event_ for a field with _name_. If such
-field is found, its value is extracted from the _record_. The value is assumed
-to be a function address, and a search is perform to find the name of this
-function. The function name (if found) and its address are printed in the _s_,
-according to the given format string _fmt_. If the argument _err_ is non-zero,
-and an error occures - it is printed in _s_.
-
-RETURN VALUE
-------------
-The _tep_print_num_field()_ and _tep_print_func_field()_ functions return 1
-on success, -1 in case of an error or 0 if the print buffer _s_ is full.

-DESCRIPTION
------------
-Filters can be attached to traced events. They can be used to filter out various
-events when outputting them. Each event can be filtered based on its parameters,
-described in the event's format file. This set of functions can be used to
-create, delete, modify and attach event filters.
-
-The _tep_filter_alloc()_ function creates a new event filter. The _tep_ argument
-is the trace event parser context.
-
-The _tep_filter_free()_ function frees an event filter and all resources that it
-had used.
-
-The _tep_filter_reset()_ function removes all rules from an event filter and
-resets it.
-
-The _tep_filter_add_filter_str()_ function adds a new rule to the _filter_. The
-_filter_str_ argument is the filter string, that contains the rule.
-
-The _tep_event_filtered()_ function checks if the event with _event_id_ has
-_filter_.
-
-The _tep_filter_remove_event()_ function removes a _filter_ for an event with
-_event_id_.
-
-The _tep_filter_match()_ function tests if a _record_ matches given _filter_.
-
-The _tep_filter_copy()_ function copies a _source_ filter into a _dest_ filter.
-
-The _tep_filter_compare()_ function compares two filers - _filter1_ and _filter2_.
-
-The _tep_filter_make_string()_ function constructs a string, displaying
-the _filter_ contents for given _event_id_.
-
-The _tep_filter_strerror()_ function copies the _filter_ error buffer into the
-given _buf_ with the size _buflen_. If the error buffer is empty, in the _buf_
-is copied a string, describing the error _err_.
-
-RETURN VALUE

-The _tep_filter_alloc()_ function returns a pointer to the newly created event
-filter, or NULL in case of an error.
-
-The _tep_filter_add_filter_str()_ function returns 0 if the rule was
-successfully added or a negative error code.  Use _tep_filter_strerror()_ to see
-actual error message in case of an error.
-
-The _tep_event_filtered()_ function returns 1 if the filter is found for given
-event, or 0 otherwise.
-
-The _tep_filter_remove_event()_ function returns 1 if the vent was removed, or
-0 if the event was not found.

---
-
-DESCRIPTION
------------
-Some tools may have already a way to resolve the kernel functions. These APIs
-allow them to keep using it instead of duplicating all the entries inside.
-
-The _tep_func_resolver_t_ type is the prototype of the alternative kernel
-functions resolver. This function receives a pointer to its custom context
-(set with the _tep_set_function_resolver()_ call ) and the address of a kernel
-function, which has to be resolved. In case of success, it should return
-the name of the function and its module (if any) in _modp_.
-
-The _tep_set_function_resolver()_ function registers _func_ as an alternative
-kernel functions resolver. The _tep_ argument is trace event parser context.
-The _priv_ argument is a custom context of the _func_ function. The function
-resolver is used by the APIs _tep_find_function()_,
-_tep_find_function_address()_, and _tep_print_func_field()_ to resolve
-a function address to a function name.
-
-The _tep_reset_function_resolver()_ function resets the kernel functions
-resolver to the default function.  The _tep_ argument is trace event parser
-context.
-
-
-These APIs can be used to find function name and start address, by given
-address. The given address does not have to be exact, it will select
-the function that would contain it.
-
-The _tep_find_function()_ function returns the function name, which contains the
-given address _addr_. The _tep_ argument is the trace event parser context.
-
-The _tep_find_function_address()_ function returns the function start address,
-by given address _addr_. The _addr_ does not have to be exact, it will select
-the function that would contain it. The _tep_ argument is the trace event
-parser context.
-
-The _tep_register_function()_ function registers a function name mapped to an
-address and (optional) module. This mapping is used in case the function tracer
-or events have "%pS" parameter in its format string. It is common to pass in
-the kallsyms function names with their corresponding addresses with this
-function. The _tep_ argument is the trace event parser context. The _name_ is
-the name of the function, the string is copied internally. The _addr_ is the
-start address of the function. The _mod_ is the kernel module the function may
-be in (NULL for none).
-
-The _tep_register_print_string()_ function  registers a string by the address
-it was stored in the kernel. Some strings internal to the kernel with static
-address are passed to certain events. The "%s" in the event's format field
-which has an address needs to know what string would be at that address. The
-tep_register_print_string() supplies the parsing with the mapping between kernel
-addresses and those strings. The _tep_ argument is the trace event parser
-context. The _fmt_ is the string to register, it is copied internally.
-The _addr_ is the address the string was located at.
-
-
-RETURN VALUE
-------------
-The _tep_set_function_resolver()_ function returns 0 in case of success, or -1
-in case of an error.
-
-The _tep_find_function()_ function returns the function name, or NULL in case
-it cannot be found.
-
-The _tep_find_function_address()_ function returns the function start address,
-or 0 in case it cannot be found.
-
-The _tep_register_function()_ function returns 0 in case of success. In case of
-an error -1 is returned, and errno is set to the appropriate error number.
-
-The _tep_register_print_string()_ function returns 0 in case of success. In case
-of an error -1 is returned, and errno is set to the appropriate error number.

---
-
-DESCRIPTION
------------
-These are the main functions to create and destroy tep_handle - the main
-structure, representing the trace event parser context. This context is used as
-the input parameter of most library APIs.
-
-The _tep_alloc()_ function allocates and initializes the tep context.
-
-The _tep_free()_ function will decrement the reference of the _tep_ handler.
-When there is no more references, then it will free the handler, as well
-as clean up all its resources that it had used. The argument _tep_ is
-the pointer to the trace event parser context.
-
-The _tep_ref()_ function adds a reference to the _tep_ handler.
-
-The _tep_unref()_ function removes a reference from the _tep_ handler. When
-the last reference is removed, the _tep_ is destroyed, and all resources that
-it had used are cleaned up.
-
-The _tep_ref_get()_ functions gets the current references of the _tep_ handler.
-
-RETURN VALUE
-------------
-_tep_alloc()_ returns a pointer to a newly created tep_handle structure.
-NULL is returned in case there is not enough free memory to allocate it.
-
-_tep_ref_get()_ returns the current references of _tep_.
-If _tep_ is NULL, 0 is returned.

-DESCRIPTION
------------
-These functions retrieve information from kernel context, stored in tracefs

-This information is retrieved from tracefs events/header_page, "commit" field.
-
-The _tep_get_header_timestamp_size()_ function returns the size of timestamps,
-in kernel context. The _tep_ argument is trace event parser context. This
-information is retrieved from tracefs events/header_page, "timestamp" field.
-
-The _tep_is_old_format()_ function returns true if the kernel predates
-the addition of events/header_page, otherwise it returns false.
-
-RETURN VALUE
-------------
-The _tep_get_header_page_size()_ function returns the size of a long integer,
-in bytes.
-
-The _tep_get_header_timestamp_size()_ function returns the size of timestamps,
-in bytes.
-
-The _tep_is_old_format()_ function returns true, if an old kernel is used to
-generate the tracing data, which has no event/header_page. If the kernel is new,
-or _tep_ is NULL, false is returned.

-NAME
-----
-tep_is_bigendian, tep_is_local_bigendian, tep_set_local_bigendian - Get / set
-the endianness of the local machine.
-
-SYNOPSIS
---------
-[verse]
---
-*#include <event-parse.h>*
-
-enum *tep_endian* {
-	TEP_LITTLE_ENDIAN = 0,
-	TEP_BIG_ENDIAN
-};

---
-
-DESCRIPTION
------------
-
-The _tep_is_bigendian()_ gets the endianness of the machine, executing
-the function.
-
-The _tep_is_local_bigendian()_ function gets the endianness of the local
-machine, saved in the _tep_ handler. The _tep_ argument is the trace event
-parser context. This API is a bit faster than _tep_is_bigendian()_, as it
-returns cached endianness of the local machine instead of checking it each time.
-
-The _tep_set_local_bigendian()_ function sets the endianness of the local
-machine in the _tep_ handler. The _tep_ argument is trace event parser context.
-The _endian_ argument is the endianness:
-[verse]
---
-	_TEP_LITTLE_ENDIAN_ - the machine is little endian,
-	_TEP_BIG_ENDIAN_ - the machine is big endian.
---
-
-RETURN VALUE
-------------
-The _tep_is_bigendian()_ function returns non zero if the endianness of the
-machine, executing the code, is big endian and zero otherwise.
-
-The _tep_is_local_bigendian()_ function returns true, if the endianness of the
-local machine, saved in the _tep_ handler, is big endian, or false otherwise.

-NAME
-----
-tep_parse_event, tep_parse_format - Parse the event format information
-
-SYNOPSIS
---------
-[verse]
---
-*#include <event-parse.h>*
-
-enum tep_errno *tep_parse_event*(struct tep_handle pass:[*]_tep_, const char pass:[*]_buf_, unsigned long _size_, const char pass:[*]_sys_);
-enum tep_errno *tep_parse_format*(struct tep_handle pass:[*]_tep_, struct tep_event pass:[*]pass:[*]_eventp_, const char pass:[*]_buf_, unsigned long _size_, const char pass:[*]_sys_);
---
-
-DESCRIPTION
------------
-The _tep_parse_event()_ function parses the event format and creates an event
-structure to quickly parse raw data for a given event. The _tep_ argument is
-the trace event parser context. The created event structure is stored in the
-_tep_ context. The _buf_ argument is a buffer with _size_, where the event
-format data is. The event format data can be taken from
-tracefs/events/.../.../format files. The _sys_ argument is the system of
-the event.
-
-The _tep_parse_format()_ function does the same as _tep_parse_event()_. The only
-difference is in the extra _eventp_ argument, where the newly created event
-structure is returned.
-
-RETURN VALUE
-------------
-Both _tep_parse_event()_ and _tep_parse_format()_ functions return 0 on success,
-or TEP_ERRNO__... in case of an error.
-
-EXAMPLE
--------

---
-
-DESCRIPTION
------------
-The _tep_parse_header_page()_ function parses the header page data from _buf_,
-and initializes the _tep_, trace event parser context, with it. The buffer
-_buf_ is with _size_, and is supposed to be copied from
-tracefs/events/header_page.
-
-Some old kernels do not have header page info, in this case the
-_tep_parse_header_page()_ function  can be called with _size_ equal to 0. The
-_tep_ context is initialized with default values. The _long_size_ can be used in
-this use case, to set the size of a long integer to be used.
-
-RETURN VALUE
-------------
-The _tep_parse_header_page()_ function returns 0 in case of success, or -1

-			   void pass:[*]_data_);
---
-
-DESCRIPTION
------------
-The _tep_load_plugins()_ function loads all plugins, located in the plugin
-directories. The _tep_ argument is trace event parser context.
-The plugin directories are :
-[verse]
---
-	- Directories, specified in _tep_->plugins_dir with priority TEP_PLUGIN_FIRST
-	- System's plugin directory, defined at the library compile time. It
-	  depends on the library installation prefix and usually is
-	  _(install_preffix)/lib/traceevent/plugins_
-	- Directory, defined by the environment variable _TRACEEVENT_PLUGIN_DIR_
-	- User's plugin directory, located at _~/.local/lib/traceevent/plugins_
-	- Directories, specified in _tep_->plugins_dir with priority TEP_PLUGIN_LAST
---
-Loading of plugins can be controlled by the _tep_flags_, using the
-_tep_set_flag()_ API:
-[verse]
---
-	_TEP_DISABLE_SYS_PLUGINS_	- do not load plugins, located in
-					the system's plugin directory.
-	_TEP_DISABLE_PLUGINS_		- do not load any plugins.
---
-The _tep_set_flag()_ API needs to be called before _tep_load_plugins()_, if
-loading of all plugins is not the desired case.
-
-The _tep_unload_plugins()_ function unloads the plugins, previously loaded by
-_tep_load_plugins()_. The _tep_ argument is trace event parser context. The
-_plugin_list_ is the list of loaded plugins, returned by
-the _tep_load_plugins()_ function.
-
-The _tep_load_plugins_hook_ function walks through all directories with plugins
-and calls user specified _load_plugin()_ hook for each plugin file. Only files
-with given _suffix_ are considered to be plugins. The _data_ is a user specified
-context, passed to _load_plugin()_. Directories and the walk order are the same
-as in _tep_load_plugins()_ API.
-
-RETURN VALUE
-------------
-The _tep_load_plugins()_ function returns a list of successfully loaded plugins,
-or NULL in case no plugins are loaded.
-
-EXAMPLE
--------
-[source,c]
---
-#include <event-parse.h>
-...
-struct tep_handle *tep = tep_alloc();
-...
-struct tep_plugin_list *plugins = tep_load_plugins(tep);

-
-DESCRIPTION
------------
-This set of functions can be used to extract common fields from a record.
-
-The _tep_data_type()_ function gets the event id from the record _rec_.
-It reads the "common_type" field. The _tep_ argument is the trace event parser
-context.
-
-The _tep_data_pid()_ function gets the process id from the record _rec_.
-It reads the "common_pid" field. The _tep_ argument is the trace event parser
-context.
-
-The _tep_data_preempt_count()_ function gets the preemption count from the
-record _rec_. It reads the "common_preempt_count" field. The _tep_ argument is
-the trace event parser context.
-
-The _tep_data_flags()_ function gets the latency flags from the record _rec_.
-It reads the "common_flags" field. The _tep_ argument is the trace event parser
-context. Supported latency flags are:
-[verse]
---
-	_TRACE_FLAG_IRQS_OFF_,		Interrupts are disabled.
-	_TRACE_FLAG_IRQS_NOSUPPORT_,	Reading IRQ flag is not supported by the architecture.
-	_TRACE_FLAG_NEED_RESCHED_,	Task needs rescheduling.
-	_TRACE_FLAG_HARDIRQ_,		Hard IRQ is running.
-	_TRACE_FLAG_SOFTIRQ_,		Soft IRQ is running.

-
-SYNOPSIS
---------
-[verse]
---
-*#include <event-parse.h>*
-
-enum *tep_reg_handler* {
-	_TEP_REGISTER_SUCCESS_,
-	_TEP_REGISTER_SUCCESS_OVERWRITE_,

-
-typedef int (*pass:[*]tep_event_handler_func*)(struct trace_seq pass:[*]s, struct tep_record pass:[*]record, struct tep_event pass:[*]event, void pass:[*]context);
---
-
-DESCRIPTION
------------
-The _tep_register_event_handler()_ function registers a handler function,
-which is going to be called to parse the information for a given event.
-The _tep_ argument is the trace event parser context. The _id_ argument is
-the id of the event. The _sys_name_ argument is the name of the system,
-the event belongs to. The _event_name_ argument is the name of the event.
-If _id_ is >= 0, it is used to find the event, otherwise _sys_name_ and
-_event_name_ are used. The _func_ is a pointer to the function, which is going
-to be called to parse the event information. The _context_ argument is a pointer
-to the context data, which will be passed to the _func_. If a handler function
-for the same event is already registered, it will be overridden with the new
-one. This mechanism allows a developer to override the parsing of a given event.
-If for some reason the default print format is not sufficient, the developer
-can register a function for an event to be used to parse the data instead.
-
-The _tep_unregister_event_handler()_ function unregisters the handler function,
-previously registered with _tep_register_event_handler()_. The _tep_ argument
-is the trace event parser context. The _id_, _sys_name_, _event_name_, _func_,
-and _context_ are the same arguments, as when the callback function _func_ was
-registered.
-
-The _tep_event_handler_func_ is the type of the custom event handler
-function. The _s_ argument is the trace sequence, it can be used to create a
-custom string, describing the event. A _record_  to get the event from is passed
-as input parameter and also the _event_ - the handle to the record's event. The
-_context_ is custom context, set when the custom event handler is registered.
-
-RETURN VALUE
-------------
-The _tep_register_event_handler()_ function returns _TEP_REGISTER_SUCCESS_
-if the new handler is registered successfully or
-_TEP_REGISTER_SUCCESS_OVERWRITE_ if an existing handler is overwritten.
-If there is not  enough memory to complete the registration,
-TEP_ERRNO__MEM_ALLOC_FAILED is returned.
-
-The _tep_unregister_event_handler()_ function returns 0 if _func_ was removed
-successful or, -1 if the event was not found.
-
-The _tep_event_handler_func_ should return -1 in case of an error,
-or 0 otherwise.

-
-SYNOPSIS

-[verse]
---
-*#include <event-parse.h>*
-
-enum *tep_func_arg_type* {
-	TEP_FUNC_ARG_VOID,
-	TEP_FUNC_ARG_INT,
-	TEP_FUNC_ARG_LONG,

-

-int *tep_unregister_print_function*(struct tep_handle pass:[*]_tep_, tep_func_handler _func_, char pass:[*]_name_);
---
-
-DESCRIPTION
------------
-Some events may have helper functions in the print format arguments.
-This allows a plugin to dynamically create a way to process one of
-these functions.
-
-The _tep_register_print_function()_ registers such helper function. The _tep_
-argument is the trace event parser context. The _func_ argument  is a pointer
-to the helper function. The _ret_type_ argument is  the return type of the
-helper function, value from the _tep_func_arg_type_ enum. The _name_ is the name
-of the helper function, as seen in the print format arguments. The _..._ is a
-variable list of _tep_func_arg_type_ enums, the _func_ function arguments.
-This list must end with _TEP_FUNC_ARG_VOID_. See 'EXAMPLE' section.
-
-The _tep_unregister_print_function()_ unregisters a helper function, previously
-registered with _tep_register_print_function()_. The _tep_ argument is the
-trace event parser context. The _func_ and _name_ arguments are the same, used
-when the helper function was registered.
-
-The _tep_func_handler_ is the type of the helper function. The _s_ argument is
-the trace sequence, it can be used to create a custom string.
-The _args_  is a list of arguments, defined when the helper function was
-registered.
-
-RETURN VALUE
-------------
-The _tep_register_print_function()_ function returns 0 in case of success.
-In case of an error, TEP_ERRNO_... code is returned.
-
-The _tep_unregister_print_function()_ returns 0 in case of success, or -1 in
-case of an error.
-
-EXAMPLE
--------
-Some events have internal functions calls, that appear in the print format
-output. For example "tracefs/events/i915/g4x_wm/format" has:
-[source,c]
---
-print fmt: "pipe %c, frame=%u, scanline=%u, wm %d/%d/%d, sr %s/%d/%d/%d, hpll %s/%d/%d/%d, fbc %s",
-	    ((REC->pipe) + 'A'), REC->frame, REC->scanline, REC->primary,
-	    REC->sprite, REC->cursor, yesno(REC->cxsr), REC->sr_plane,
-	    REC->sr_cursor, REC->sr_fbc, yesno(REC->hpll), REC->hpll_plane,
-	    REC->hpll_cursor, REC->hpll_fbc, yesno(REC->fbc)
---
-Notice the call to function _yesno()_ in the print arguments. In the kernel
-context, this function has the following implementation:
-[source,c]
---
-static const char *yesno(int x)
-{
-	static const char *yes = "yes";
-	static const char *no = "no";
-
-	return x ? yes : no;
-}
---
-The user space event parser has no idea how to handle this _yesno()_ function.
-The _tep_register_print_function()_ API can be used to register a user space
-helper function, mapped to the kernel's _yesno()_:
-[source,c]
---
-#include <event-parse.h>
-#include <trace-seq.h>
-...
-struct tep_handle *tep = tep_alloc();
-...
-static const char *yes_no_helper(int x)
-{
-	return x ? "yes" : "no";
-}
-...
-	if ( tep_register_print_function(tep,
-				    yes_no_helper,
-				    TEP_FUNC_ARG_STRING,
-				    "yesno",
-				    TEP_FUNC_ARG_INT,
-				    TEP_FUNC_ARG_VOID) != 0) {
-		/* Failed to register yes_no_helper function */
-	}
-
-/*
-   Now, when the event parser encounters this yesno() function, it will know
-   how to handle it.
-*/
-...
-	if (tep_unregister_print_function(tep, yes_no_helper, "yesno") != 0) {
-		/* Failed to unregister yes_no_helper function */
-	}

-DESCRIPTION
------------
-Trace event parser context flags are defined in *enum tep_flag*:
-[verse]
---
-_TEP_NSEC_OUTPUT_ - print event's timestamp in nano seconds, instead of micro seconds.
-_TEP_DISABLE_SYS_PLUGINS_ - disable plugins, located in system's plugin
-			directory. This directory is defined at library compile
-			time, and usually depends on library installation
-			prefix: (install_preffix)/lib/traceevent/plugins
-_TEP_DISABLE_PLUGINS_ - disable all library plugins:
-			- in system's plugin directory
-			- in directory, defined by the environment variable _TRACEEVENT_PLUGIN_DIR_
-			- in user's home directory, _~/.traceevent/plugins_
---
-Note: plugin related flags must me set before calling _tep_load_plugins()_ API.
-
-The _tep_set_flag()_ function sets _flag_ to _tep_ context.
-
-The _tep_clear_flag()_ function clears _flag_ from _tep_ context.
-
-The _tep_test_flag()_ function tests if _flag_ is set to _tep_ context.
-
-RETURN VALUE
-------------
-_tep_test_flag()_ function returns true if _flag_ is set, false otherwise.

-NAME
-----
-tep_strerror - Returns a string describing regular errno and tep error number.
-
-SYNOPSIS
---------
-[verse]
---
-*#include <event-parse.h>*
-
-int *tep_strerror*(struct tep_handle pass:[*]_tep_, enum tep_errno _errnum_, char pass:[*]_buf_, size_t _buflen_);
-
---
-DESCRIPTION
------------
-The _tep_strerror()_ function converts tep error number into a human
-readable string.
-The _tep_ argument is trace event parser context. The _errnum_ is a regular
-errno, defined in errno.h, or a tep error number. The string, describing this
-error number is copied in the _buf_ argument. The _buflen_ argument is
-the size of the _buf_.
-
-It as a thread safe wrapper around strerror_r(). The library function has two
-different behaviors - POSIX and GNU specific. The _tep_strerror()_ API always
-behaves as the POSIX version - the error string is copied in the user supplied
-buffer.
-
-RETURN VALUE
-------------
-The _tep_strerror()_ function returns 0, if a valid _errnum_ is passed and the
-string is copied into _buf_. If _errnum_ is not a valid error number,
--1 is returned and _buf_ is not modified.
-
-EXAMPLE
--------
-[source,c]
---
-#include <event-parse.h>
-...
-struct tep_handle *tep = tep_alloc();
-...
-char buf[32];
-char *pool = calloc(1, 128);
-if (tep == NULL) {

---
-
-DESCRIPTION
------------
-Trace sequences are used to allow a function to call several other functions
-to create a string of data to use.
-
-The _trace_seq_init()_ function initializes the trace sequence _s_.
-
-The _trace_seq_destroy()_ function destroys the trace sequence _s_ and frees
-all its resources that it had used.
-
-The _trace_seq_reset()_ function re-initializes the trace sequence _s_. All
-characters already written in _s_ will be deleted.
-
-The _trace_seq_terminate()_ function terminates the trace sequence _s_. It puts
-the null character pass:['\0'] at the end of the buffer.
-
-The _trace_seq_putc()_ function puts a single character _c_ in the trace
-sequence _s_.
-
-The _trace_seq_puts()_ function puts a NULL terminated string _str_ in the
-trace sequence _s_.
-
-The _trace_seq_printf()_ function puts a formated string _fmt _with
-variable arguments _..._ in the trace sequence _s_.
-
-The _trace_seq_vprintf()_ function puts a formated string _fmt _with
-list of arguments _args_ in the trace sequence _s_.
-
-The _trace_seq_do_printf()_ function prints the buffer of trace sequence _s_ to
-the standard output stdout.
-
-The _trace_seq_do_fprintf()_ function prints the buffer of trace sequence _s_
-to the given file _fp_.
-
-RETURN VALUE
-------------
-Both _trace_seq_putc()_ and _trace_seq_puts()_ functions return the number of
-characters put in the trace sequence, or 0 in case of an error
-
-Both _trace_seq_printf()_ and _trace_seq_vprintf()_ functions return 0 if the
-trace oversizes the buffer's free space, the number of characters printed, or
-a negative value in case of an error.
-
-Both _trace_seq_do_printf()_ and _trace_seq_do_fprintf()_ functions return the
-number of printed characters, or -1 in case of an error.

-DESCRIPTION
------------
-The libtraceevent(3) library provides APIs to access kernel tracepoint events,
-located in the tracefs file system under the events directory.
-
-ENVIRONMENT
------------
-[verse]
---
-TRACEEVENT_PLUGIN_DIR
-	Additional plugin directory. All shared object files, located in this directory will be loaded as traceevent plugins.
---
-
-FILES
------
-[verse]
---
-*event-parse.h*
-	Header file to include in order to have access to the library APIs.
-*trace-seq.h*
-	Header file to include in order to have access to trace sequences related APIs.
-	Trace sequences are used to allow a function to call several other functions
-	to create a string of data to use.
-*-ltraceevent*
-	Linker switch to add when building a program that uses the library.
