From: Andi Kleen <ak@linux.intel.com>
When profiling the kernel with the 'srcfile' sort key it's common to
"get stuck" in include. For example a lot of code uses current or other
inlines, so they get accounted to some random include file. This is not
very useful as a high level categorization.
For example just profiling the idle loop usually shows mostly inlines,
so you never see the actual cpuidle file.
This patch changes the 'srcfile' sort key to always unwind the inline
stack using BFD/DWARF. So we always account to the base function that
called the inline.
In a few cases include is still shown (for example for MSR accesses),
but that is because they get inlining expanded as part of assigning to a
global function pointer. For the majority it works fine though.
v2: Use simpler while loop. Add maximum iteration count.

From: He Kuang <hekuang@huawei.com>
This patch copies filter.h from include/linux/kernel.h to
tools/include/linux/filter.h to enable other libraries to use macros in it,
like libbpf which will be introduced by further patches.
Currently, the filter.h copy only contains the useful macros needed by
libbpf for not introducing too much dependence.
tools/perf/MANIFEST is also updated for 'make perf-*-src-pkg'.
One change:
The 'imm' field of BPF_EMIT_CALL becomes ((FUNC) - BPF_FUNC_unspec) to
suit user space code generator.

Support helper function __get_dynamic_array_len() in libtraceevent, this
function is used accompany with __print_array() or __print_hex(), but
currently it is not an available function in the function list of
process_function().
The total allocated length of the dynamic array is embedded in the top
half of __data_loc_##item field. This patch adds new arg type
PRINT_DYNAMIC_ARRAY_LEN to return the length to eval_num_arg(),

From: Kan Liang <kan.liang@intel.com>
This patch stores the cpu socket_id and core_id in a perf.data header,
and reads them into the perf_env struct when processing perf.data files.
The changes modifies the CPU_TOPOLOGY section, making sure it is
backward/forward compatible.
The patch checks the section size before reading the core and socket ids.
It never reads data crossing the section boundary. An old perf binary
without this patch can also correctly read the perf.data from a new perf
with this patch.
Because the new info is added at the end of the cpu_topology section, an
old perf tool ignores the extra data.
Examples:
1. New perf with this patch read perf.data from an old perf without the
patch:
$ perf_new report -i perf_old.data --header-only -I
......
# sibling threads : 33
# sibling threads : 34
# sibling threads : 35
# Core ID and Socket ID information is not available
# node0 meminfo : total = 32823872 kB, free = 29315548 kB
# node0 cpu list : 0-17,36-53
......
2. Old perf without the patch reads perf.data from a new perf with the
patch:
$ perf_old report -i perf_new.data --header-only -I
......
# sibling threads : 33
# sibling threads : 34
# sibling threads : 35
# node0 meminfo : total = 32823872 kB, free = 29190932 kB
# node0 cpu list : 0-17,36-53
......
3. New perf read new perf.data:
$ perf_new report -i perf_new.data --header-only -I
......
# sibling threads : 33
# sibling threads : 34
# sibling threads : 35
# CPU 0: Core ID 0, Socket ID 0
# CPU 1: Core ID 1, Socket ID 0
......
# CPU 61: Core ID 10, Socket ID 1
# CPU 62: Core ID 11, Socket ID 1
# CPU 63: Core ID 16, Socket ID 1
# node0 meminfo : total = 32823872 kB, free = 29190932 kB
# node0 cpu list : 0-17,36-53

Since 3b3eb0445 running perf stat on a system without
backend-stalled-cycles spits out ugly warnings by default.
Since that is quite common, make the message a debug message only.
We know anyways that the counter wasn't read by the normal <unsupported>
output.

From: Jiri Olsa <jolsa@kernel.org>
Renaming all functions touching tracing_path under same namespace. New
interface is:
char tracing_path[];
- tracing mount path
char tracing_events_path[];
- tracing mount/events path
void tracing_path_set(const char *mountpoint);
- setting directly tracing_path(_events), used by --debugfs-dir option
const char *tracing_path_mount(void);
- initial setup of tracing_(events)_path, called from perf.c
mounts debugfs/tracefs if needed and possible
char *get_tracing_file(const char *name);
void put_tracing_file(char *file);
- get/put tracing file path

Moving tracing_path interface into api/fs/tracing_path.c out of util.c.
It seems generic enough to be used by others, and I couldn't think of
better place.

From: Jiri Olsa <jolsa@kernel.org>
Moving debugfs__strerror_open out of api/fs/debugfs.c, because it's not
debugfs specific. It'll be changed to consider tracefs mount as well in
following patches.
Renaming it into tracing_path__strerror_open_tp to fit into the
namespace. No functional change is intended.

Too late for this one, but to augment your chances of having your
reviewed-by tags applied, please reply-to the original message... So
that when I switch to threaded view in my MUA I can see the
acks/reviewed-by tags.
If you do like on this one, I will not easily match tags to patches.
And we want those tags, if you took the time to review the patches
thoroughly :-)

Add FSTYPE__configured() (where FSTYPE is one of sysfs, procfs, debugfs,
tracefs) interface that returns bool state of the filesystem mount:
true - mounted, false - not mounted
It will not try to mount the filesystem.

From: Adrian Hunter <adrian.hunter@intel.com>
perf tools has a copy of the x86 instruction decoder used by the kernel.
The expectation is that the copy will be kept more-or-less in-synch with
the kernel version. Consequently it is helpful to know if there are
differences.
This patch adds a check into the perf tools build so that a diff is done
on the sources, and a warning is printed if they are different. Note
that the warning is not fatal and the build continues as normal.
The check is done as part of building the instruction decoder, so, like
a compiler warning, it is not seen unless the instruction decoder has to
be re-compiled. e.g.
$ make -C tools/perf >/dev/null
$ echo "/* blah */" >> tools/perf/util/intel-pt-decoder/inat_types.h
$ make -C tools/perf >/dev/null
Warning: Intel PT: x86 instruction decoder differs from kernel
$ make -C tools/perf >/dev/null

From: Adrian Hunter <adrian.hunter@intel.com>
Add a new test titled:
Test x86 instruction decoder - new instructions
The purpose of this test is to check the instruction decoder after new
instructions have been added. Initially, MPX instructions are tested
which are already supported, but the definitions in x86-opcode-map.txt
will be tweaked in a subsequent patch, after which this test can be run
to verify those changes.
The data for the test comes from assembly language instructions in
insn-x86-dat-src.c which is converted into bytes by the scripts
gen-insn-x86-dat.sh and gen-insn-x86-dat.awk, and included into the test
program insn-x86.c as insn-x86-dat-32.c and insn-x86-dat-64.c.
The conversion is not done as part of the perf tools build because the
test data must be under (git) change control in order for the test to be
repeatably-correct. Also it may require a recent version of binutils.

From: Adrian Hunter <adrian.hunter@intel.com>
The MPX instructions are presently not described in the SDM
opcode maps, and there are not encoding characters for bnd
registers, address method or operand type. So the kernel
opcode map is using 'Gv' for bnd registers and 'Ev' for
everything else. That is fine because the instruction
decoder does not use that information anyway, except as
an indication that there is a ModR/M byte.
Nevertheless, in some cases the 'Gv' and 'Ev' are the wrong
way around, BNDLDX and BNDSTX have 2 operands not 3, and it
wouldn't hurt to identify the mandatory prefixes.
This has no effect on the decoding of valid instructions,
but the addition of the mandatory prefixes will cause some
invalid instructions to error out that wouldn't have
previously.
Note that perf tools has a copy of the instruction decoder
and provides a test for new instructions which includes MPX
instructions e.g.
$ perf test "x86 ins"
39: Test x86 instruction decoder - new instructions : Ok
Or to see the details:
$ perf test -v "x86 ins"
Commiter notes:
And to see these MPX instructions specifically:
$ perf test -v "x86 ins" 2>&1 | grep bndldx | head -3
Decoded ok: 0f 1a 00 bndldx (%eax),%bnd0
Decoded ok: 0f 1a 05 78 56 34 12 bndldx 0x12345678,%bnd0
Decoded ok: 0f 1a 18 bndldx (%eax),%bnd3
$ perf test -v "x86 ins" 2>&1 | grep bndstx | head -3
Decoded ok: 0f 1b 00 bndstx %bnd0,(%eax)
Decoded ok: 0f 1b 05 78 56 34 12 bndstx %bnd0,0x12345678
Decoded ok: 0f 1b 18 bndstx %bnd3,(%eax)

Intel SHA Extensions are explained in the Intel Architecture
Instruction Set Extensions Programing Reference (Oct 2014).
There are 7 new instructions. Add them to the op code map
and the perf tools new instructions test. e.g.
$ tools/perf/perf test "x86 ins"
39: Test x86 instruction decoder - new instructions : Ok
Or to see the details:
$ tools/perf/perf test -v "x86 ins" 2>&1 | grep sha
Committer note:
3 lines of details, for the curious:
$ perf test -v "x86 ins" 2>&1 | grep sha256msg1 | tail -3
Decoded ok: 0f 38 cc 84 08 78 56 34 12 sha256msg1 0x12345678(%rax,%rcx,1),%xmm0

From: Adrian Hunter <adrian.hunter@intel.com>
Intel Architecture Instruction Set Extensions Programing Reference (Oct
2014) describes 3 new memory instructions, namely clflushopt, clwb and
pcommit. Add them to the op code map and the perf tools new
instructions test. e.g.
$ tools/perf/perf test "x86 ins"
39: Test x86 instruction decoder - new instructions : Ok
Or to see the details:
$ tools/perf/perf test -v "x86 ins"

Add rdpkru and wrpkru to the op code map and the perf tools new
instructions test. In the case of the test, only the bytes can be
tested at the moment since binutils doesn't support the instructions
yet. To run the test:
$ tools/perf/perf test "x86 ins"
39: Test x86 instruction decoder - new instructions : Ok
Or to see the details:
$ tools/perf/perf test -v "x86 ins" 2>&1 | grep pkru
For information about rdpkru and wrpkru, refer the Intel SDM.

From: Adrian Hunter <adrian.hunter@intel.com>
Add support for selecting and processing PERF_RECORD_SWITCH events for
use by Intel PT. If they are available, they will be used in preference
to sched_switch events.
This enables an unprivileged user to trace multi-threaded or
multi-process workloads with any level of perf_event_paranoid. However
it depends on kernel support for PERF_RECORD_SWITCH.
Without this patch, tracing a multi-threaded workload will decode
without error but all the data will be attributed to the main thread.
Without this patch, tracing a multi-process workload will result in
decoder errors because the decoder will not know which executable is
executing.

The add_perf_probe_events() does 3 things:
1. convert all perf events to trace events
2. add all trace events to kernel
3. cleanup all trace events
But sometimes we need to do something with the trace events. So split
the funtion into three, so that it can access intermediate trace events
via struct __event_package if needed.

From: Wang Nan <wangnan0@huawei.com>
This patch drops struct __event_package structure. Instead, it adds a
'struct trace_probe_event' pointer to 'struct perf_probe_event'.
The trace_probe_event information gives further patches a chance to
access actual probe points and actual arguments.
Using them, 'perf probe' can get the whole list of added probes and
print them at once.
Other users like the upcoming bpf_loader will be able to attach one bpf
program to different probing points of an inline function (which has
multiple probing points) and glob functions.
Moreover, by reading the arguments information, bpf code for reading
those arguments can be generated.

From: Namhyung Kim <namhyung@kernel.org>
Showing actual trace event when adding perf events is only needed in
perf probe command. But the add functionality itself can be used by
other places. So move the printing code into the cmd_probe().
Also it combines the output if more than one event is added.
Before:
$ sudo perf probe -a do_fork -a do_exit
Added new event:
probe:do_fork (on do_fork)
You can now use it in all perf tools, such as:
perf record -e probe:do_fork -aR sleep 1
Added new events:
probe:do_exit (on do_exit)
probe:do_exit_1 (on do_exit)
You can now use it in all perf tools, such as:
perf record -e probe:do_exit_1 -aR sleep 1
After:
$ sudo perf probe -a do_fork -a do_exit
Added new events:
probe:do_fork (on do_fork)
probe:do_exit (on do_exit)
probe:do_exit_1 (on do_exit)
You can now use it in all perf tools, such as:
perf record -e probe:do_exit_1 -aR sleep 1

The del_perf_probe_events() does 2 things:
1. find existing events which match to filter
2. delete such trace events from kernel
But sometimes we need to do something with the trace events. So split
the funtion into two, so that it can access intermediate trace events
name using strlist if needed.

Showing actual trace event when deleteing perf events is only needed in
perf probe command. But the add functionality itself can be used by
other places. So move the printing code into the cmd_probe().
The output is not changed.
