API headers from libbpf should not be accessed directly from the
library's source directory. Instead, they should be exported with "make
install_headers". Let's adjust perf's Makefile to install those headers
locally when building libbpf.

- Fix $(LIBBPF_OUTPUT) when $(OUTPUT) is null.
- Make sure the recipe for $(LIBBPF_OUTPUT) is not under a "ifdef".

On anARM machine, kernel symbols from modules can be resolved to $a
instead of printing the actual symbol name. Ignore symbols starting with
"$" when building kallsyms rbtree.
A sample stacktrace is shown as follows:
c0f2e39c schedule_hrtimeout+0x14 ([kernel.kallsyms])
bf4a66d8 $a+0x78 ([test_module])
c0a4f5f4 kthread+0x15c ([kernel.kallsyms])
c0a001f8 ret_from_fork+0x14 ([kernel.kallsyms])
On an ARM machine, $a/$d symbols are used by the compiler to mark the
beginning of code/data part in code section. These symbols are filtered
out when linking vmlinux(see scripts/kallsyms.c ignored_prefixes), but
are left on modules. So there are $a symbols in /proc/kallsyms which
share the same addresses with the actual module symbols and confuses
perf when resolving symbols.
After this patch, the module symbol name is printed:
c0f2e39c schedule_hrtimeout+0x14 ([kernel.kallsyms])
bf4a66d8 test_func+0x78 ([test_module])
c0a4f5f4 kthread+0x15c ([kernel.kallsyms])

Perf tool sets exclude_guest by default while calling perf_event_open().
Because IBS does not have filtering capability, it always gets rejected
by IBS PMU driver and thus perf falls back to non-precise sampling. Fix
it by not setting exclude_guest by default on AMD.
Before:
$ sudo ./perf record -C 0 -vvv true |& grep precise
precise_ip 3
decreasing precise_ip by one (2)
precise_ip 2
decreasing precise_ip by one (1)
precise_ip 1
decreasing precise_ip by one (0)
After:
$ sudo ./perf record -C 0 -vvv true |& grep precise
precise_ip 3
decreasing precise_ip by one (2)
precise_ip 2
Committer notes:
Fixup init to zero for perf_env in older compilers:
arch/x86/util/evsel.c:15:26: error: missing field 'os_release' initializer [-Werror,-Wmissing-field-initializers]
struct perf_env env = {0};
^
Committer notes:
Namhyung remarked:
It'd be nice if it can cover explicit "-e cycles:pp" as well.
Ravi clarified:
For explicit :pp modifier, evsel->precise_max does not get set and thus perf
does not try with different attr->precise_ip values while exclude_guest set.
So no issue with explicit :pp:
$ sudo ./perf record -C 0 -e cycles:pp -vvv |& grep "precise_ip\|exclude_guest"
precise_ip 2
exclude_guest 1
precise_ip 2
exclude_guest 1
switching off exclude_guest, exclude_host
precise_ip 2
^C
Also, with :P modifier, evsel->precise_max gets set but exclude_guest does
not and thus :P also works fine:
$ sudo ./perf record -C 0 -e cycles:P -vvv |& grep "precise_ip\|exclude_guest"
precise_ip 3
decreasing precise_ip by one (2)
precise_ip 2
^C

The current logic for the perf missing feature has a bug that it can
wrongly clear some modifiers like G or H. Actually some PMUs don't
support any filtering or exclusion while others do. But we check it as
a global feature.
For example, the cycles event can have 'G' modifier to enable it only in
the guest mode on x86. When you don't run any VMs it'll return 0.
# perf stat -a -e cycles:G sleep 1
Performance counter stats for 'system wide':
0 cycles:G
1.000721670 seconds time elapsed
But when it's used with other pmu events that don't support G modifier,
it'll be reset and return non-zero values.
# perf stat -a -e cycles:G,msr/tsc/ sleep 1
Performance counter stats for 'system wide':
538,029,960 cycles:G
16,924,010,738 msr/tsc/
1.001815327 seconds time elapsed
This is because of the missing feature detection logic being global.
Add a hashmap to set pmu-specific exclude_host/guest features.
Committer notes:
Fix 'perf test python' by adding a stub for evsel__find_pmu() in
tools/perf/util/python.c, document that it is used so far only for the
above reasons so that if anybody needs this in the python binding
usecases, we can revisit this.

memcpy() in the insn decoder

x86/insn: Use get_unaligned() instead of memcpy()
x86/Kconfig: Fix an unused variable error in dell-smm-hwmon
To prepare for impending deprecation of libbpf's bpf_program__get_prog_info_linear(),
pull in the function and associated helpers into the perf codebase and migrate
existing uses to the perf copy.
Since libbpf's deprecated definitions will still be visible to perf, it is necessary
to rename perf's definitions.

-F weight in perf script is broken.
# ./perf mem record
# ./perf script -F weight
Samples for 'dummy:HG' event do not have WEIGHT attribute set. Cannot
print 'weight' field.
The sample type, PERF_SAMPLE_WEIGHT_STRUCT, is an alternative of the
PERF_SAMPLE_WEIGHT sample type. They share the same space, weight. The
lower 32 bits are exactly the same for both sample type. The higher 32
bits may be different for different architecture. For a new kernel on
x86, the PERF_SAMPLE_WEIGHT_STRUCT is used. For an old kernel or other
ARCHs, the PERF_SAMPLE_WEIGHT is used.
With -F weight, current perf script will only check the input string
"weight" with the PERF_SAMPLE_WEIGHT sample type. Because the commit
ea8d0ed6ea ("perf tools: Support PERF_SAMPLE_WEIGHT_STRUCT") didn't
update the PERF_SAMPLE_WEIGHT_STRUCT sample type for perf script. For a
new kernel on x86, the check fails.
Use PERF_SAMPLE_WEIGHT_TYPE, which supports both sample types, to
replace PERF_SAMPLE_WEIGHT
Fixes: ea8d0ed6ea ("perf tools: Support PERF_SAMPLE_WEIGHT_STRUCT")

When perf.data is not written cleanly, we would like to process existing
data as much as possible (please see f_header.data.size == 0 condition
in perf_session__read_header). However, perf.data with partial data may
crash perf. Specifically, we see crash in 'perf script' for NULL
session->header.env.arch.
Fix this by checking session->header.env.arch before using it to determine
native_arch. Also split the if condition so it is easier to read.
Committer notes:
If it is a pipe, we already assume is a native arch, so no need to check
session->header.env.arch.

The branch_stack struct has bit field definition which produces
different bit ordering for big/little endian.
Because of this, when branch_stack sample is collected in a BE system
and viewed/reported in a LE system, bit fields of the branch stack are
not presented properly.
To address this issue, a evsel__bitfield_swap_branch_stack() is defined
and introduced in evsel__parse_sample.

The instruction latency information can be recorded on
some platforms, e.g., the Intel Sapphire Rapids server. With both memory
latency (weight) and the new instruction latency information, users can
easily locate the expensive load instructions, and also understand the time
spent in different stages. The users can optimize their applications in
different pipeline stages.
Add a new field "ins_lat" to filter the instruction latency information,
which is available with sample type PERF_SAMPLE_WEIGHT_STRUCT.

Show binary offsets for userspace addr with map in perf script output
with callchain.
In commit 19610184693c("perf script: Show virtual addresses instead of
offsets"), the addr shown in perf script output with callchain is changed
from binary offsets to virtual address to fix the incorrectness when
displaying symbol offset.
This is inconvenient in scenario that the binary is stripped and
symbol cannot be resolved. If someone wants to further resolve symbols for
specific binaries later, he would need an extra step to translate virtual
address to binary offset with mapping information recorded in perf.data,
which can be difficult for people not familiar with perf.
This patch modifies function sample__fprintf_callchain to print binary
offset for userspace addr with dsos, and virtual address otherwise. It
does not affect symbol offset calculation so symoff remains correct.
Before applying this patch:

time_t and as such don't have the SYS_futex syscall. This patch will
allow us to use the SYS_futex_time64 syscall on those platforms.
This also converts the futex calls to be y2038 safe (when built for a

Add a new dlfilter to show cycles.
Cycle counts are accumulated per CPU (or per thread if CPU is not recorded)
from IPC information, and printed together with the change since the last
print, at the start of each line. Separate counts are kept for branches,
instructions or other events.
Note also, the itrace A option can be useful to provide higher granularity
cycle information.
Example:
$ perf record -e intel_pt/cyc/u uname
Linux
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.044 MB perf.data ]

Normally, for cycle-acccurate mode, IPC values are an exact number of
instructions and cycles. Due to the granularity of timestamps, that happens
only when a CYC packet correlates to the event.
Support the itrace 'A' option, to use instead, the number of cycles
associated with the current timestamp. This provides IPC information for
every change of timestamp, but at the expense of accuracy. Due to the
granularity of timestamps, the actual number of cycles increases even
though the cycles reported does not. The number of instructions is known,
but if IPC is reported, cycles can be too low and so IPC is too high. Note
that inaccuracy decreases as the period of sampling increases i.e. if the
number of cycles is too low by a small amount, that becomes less
significant if the number of cycles is large.
Furthermore, it can be used in conjunction with dlfilter-show-cycles.so
to provide higher granularity cycle information.

Because _LARGEFILE64_SOURCE is set in perf, file offset sizes can be
64 bits. If a workflow needs to open /proc/kcore on a 32 bit system (for
example to decode Arm ETM kernel trace) then the size value will be
wrapped to 32 bits in the function file_size() at this line:
dso->data.file_size = st.st_size;
Setting the file_size member to be u64 fixes the issue and allows
/proc/kcore to be opened.

Originally, software only supported redirecting at most one PEBS event to
Intel PT (PEBS-via-PT) because it was not able to differentiate one event
from another. To overcome that, add support for the
PERF_RECORD_AUX_OUTPUT_HW_ID side-band event.
Committer notes:
Cast the pointer arg to for_each_set_bit() to (unsigned long *), to fix
the build on 32-bit systems.

Previously find_evsel_group was trying to share events while
mark-sweeping to eliminate unused events, this was complicated and had
issues around uncore events and grouped sharing.
This was further complicated by the event string being created while
metrics and metric groups were being added, with the string affecting
the evlist order.
This change moves deduplication before event parsing. Ungrouped events
are placed in a single combined set. Groups are checked to see if an
earlier (larger) group can support their events.
As the deduplication and sharing detection is done on metric IDs before
parsing, wildcard expansion problems with uncore events are avoided.
Overall the code is simpler while working better.
An example of failing to deduplicate can be seen with a list of metrics
like the following, where in the after case multiplexing has been
avoided:

For a metric like IPC a group of events like {instructions,cycles}:W
would be formed.
If the events names were changed in parsing then the metric expression
parser would fail to find them.
This change makes the event encoding be something like:
{instructions/metric-id=instructions/, cycles/metric-id=cycles/}
and then uses the evsel's stable metric-id value to locate the events.
This fixes the case that an event is restricted to user because of the
paranoia setting:
$ echo 2 > /proc/sys/kernel/perf_event_paranoid
$ perf stat -M IPC /bin/true
Performance counter stats for '/bin/true':
150,298 inst_retired.any:u # 0.77 IPC
187,095 cpu_clk_unhalted.thread:u
0.002042731 seconds time elapsed
0.000000000 seconds user
0.002377000 seconds sys
Adding the metric-id as a qualifier has a complication in that
qualifiers will become embedded in qualifiers.
For example, msr/tsc/ could become msr/tsc,metric-id=msr/tsc// which
will fail parse-events.
To solve this problem the metric is encoded and decoded for the
metric-id with !<num> standing in for an encoded value.
Previously ! wasn't parsed.
With this msr/tsc/ becomes msr/tsc,metric-id=msr!3tsc!3/
The metric expression parser is changed so that @ isn't changed to /,
instead this is done when the ID is encoded for parse events.
metricgroup__add_metric_non_group() and metricgroup__add_metric_weak_group()
need to inject the metric-id qualifier, so to avoid repetition they are
merged into a single metricgroup__build_event_string with error codes
more rigorously checked.
stat-shadow's prepare_metric() uses the metric-id to match the metricgroup
code.
As "metric-id=..." is added to all events, it is adding during testing
with the fake PMU.
This complicates pmu_str_check code as PE_PMU_EVENT_FAKE won't match as
part of a configuration.
The testing fake PMU case is fixed so that if a known qualifier with an
! is parsed then it isn't reported as a fake PMU.
This is sufficient to pass all testing but it and the original mechanism
are somewhat brittle.

An event like inst_retired.any on an Intel skylake is found in the
pmu-events code created from the pipeline event JSON.
The event is an alias for cpu/event=0xc0,period=2000003/ and
parse-events recognizes the event with the token PE_KERNEL_PMU_EVENT.
The parser doesn't currently allow extra configuration on such events,
except for modifiers, so:
$ perf stat -e inst_retired.any// /bin/true
event syntax error: 'inst_retired.any//'
\___ parser error
Run 'perf list' for a list of valid events
Usage: perf stat [<options>] [<command>]
-e, --event <event> event selector. use 'perf list' to list available events
This patch adds configuration to these events which can be useful for a
number of parameters like name and call-graph:
$ sudo perf record -e inst_retired.any/call-graph=lbr/ -a sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 1.856 MB perf.data (44 samples) ]
It is necessary for the metric code so that we may add metric-id values
to these events before they are parsed.

Add a new "metric-id" term to events so that metric parsing can set an
ID that can be reliably looked up.
Metric parsing currently will turn a metric like "instructions/cycles"
into a parse events string of "{instructions,cycles}:W".
However, parse-events may change "instructions" into "instructions:u" if
perf_event_paranoid=2.
When this happens expr__resolve_id currently fails as stat-shadow adds
the ID "instructions:u" to match with the counter value and the metric
tries to look up the ID just "instructions".
A later patch will use the new term.
An example of the current problem:
$ echo -1 > /proc/sys/kernel/perf_event_paranoid
$ perf stat -M IPC /bin/true
Performance counter stats for '/bin/true':
1,217,161 inst_retired.any # 0.97 IPC
1,250,389 cpu_clk_unhalted.thread
0.002064773 seconds time elapsed
0.002378000 seconds user
0.000000000 seconds sys
$ echo 2 > /proc/sys/kernel/perf_event_paranoid
$ perf stat -M IPC /bin/true
Performance counter stats for '/bin/true':
150,298 inst_retired.any:u # nan IPC
187,095 cpu_clk_unhalted.thread:u
0.002042731 seconds time elapsed
0.000000000 seconds user
0.002377000 seconds sys
Note: nan IPC is printed as an effect of "perf metric: Use NAN for
missing event IDs." but earlier versions of perf just fail with a parse
error and display no value.

A later change will add another similar string.

Modify resolution. Rather than resolving a list of metrics, resolve a
metric immediately after it is added.
This simplifies knowing the root of the metric's tree so that IDs may be
associated with it.
A bug in the current implementation is that all the IDs were placed on
the first metric in a metric group.
Rather than maintain data on IDs' parents to detect cycles, maintain
a list of visited metrics and detect cycles if the same metric is
visited twice.
Only place the root metric onto the list of metrics.

If a metric references other metrics then the same other metrics may be
referenced more than once, but the events and metric ref are only needed
once.
An example of this is in tests/parse-metric.c where DCache_L2_Hits
references the metric DCache_L2_All_Hits twice, once directly and once
through DCache_L2_All.

The runtime value is needed when recursively parsing metrics, currently
a value of 1 is passed which is incorrect.
Rather than add more arguments to the bison parser, add runtime to the
context.
Fix call sites not to pass a value. The runtime value is defaulted to 0,
which is arbitrary. In some places this replaces a value of 1, which was
also arbitrary.
This shouldn't affect anything other than PPC.
The use of 0 or 1 shouldn't matter as a proper runtime value would be
needed in a case that it did matter.

The pmu_events_map is generated at compile time and used for lookup. For
testing purposes we need to swap the map being used.
Having the pmu_events_map be non-const is misleading as it may be an out
argument.
Make it const and update uses so they work on const too.

Add list_sort.[ch] from the main kernel tree. The linux/bug.h #include
is removed due to conflicting definitions. Add check-headers and modify
perf build accordingly.
MANIFEST and python-ext-sources fixes suggested by Arnaldo.

Going forward, future generation systems can have more hierarchy
within the node/package level but currently we don't have any data source
encoding field in perf, which can be used to represent this level of data.
Add a new field called 'mem_hops' in the perf_mem_data_src structure
which can be used to represent intra-node/package or inter-node/off-package
details. This field is of size 3 bits where PERF_MEM_HOPS_{NA, 0..6} value
can be used to present different hop levels data.
Also add corresponding macros to define mem_hop field values
and shift value.
Currently we define macro for HOPS_0 which corresponds
to data coming from another core but same node.
Add functionality to represent mem_hop field data in
perf_mem__lvl_scnprintf function with the help of added string
array called mem_hops.
For ex: Encodings for mem_hops fields with L2 cache:
L2 - local L2
L2 | REMOTE | HOPS_0 - remote core, same node L2
Since with the addition of HOPS field, now remote can be used to
denote cache access from the same node but different core, a check
is added in the c2c_decode_stats function to set mrem only when HOPS
is zero along with set remote field.

Add a comment about PERF_MEM_LVL_* namespace being depricated
to some extent in favour of added PERF_MEM_{LVLNUM_,REMOTE_,SNOOPX_}
fields.
Remove an extra line present in perf_mem__lvl_scnprintf function.
