Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Thomas Gleixner:
"A bunch of perf tooling fixes:
- Make the Intel PT SQL viewer more robust
- Make the Intel PT debug log more useful
- Support weak groups in perf record so it's behaving the same way as
perf stat
- Display the LBR stats in callchain entries properly in perf top
- Handle different PMu names with common prefix properlin in pert
stat
- Start syscall augmenting in perf trace. Preparation for
architecture independent eBPF instrumentation of syscalls.
- Fix build breakage in JVMTI perf lib
- Fix arm64 tools build failure wrt smp_load_{acquire,release}"
* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
perf tools: Do not zero sample_id_all for group members
perf tools: Fix undefined symbol scnprintf in libperf-jvmti.so
perf beauty: Use SRCARCH, ARCH=x86_64 must map to "x86" to find the headers
perf intel-pt: Add MTC and CYC timestamps to debug log
perf intel-pt: Add more event information to debug log
perf scripts python: exported-sql-viewer.py: Fix table find when table re-ordered
perf scripts python: exported-sql-viewer.py: Add help window
perf scripts python: exported-sql-viewer.py: Add Selected branches report
perf scripts python: exported-sql-viewer.py: Fall back to /usr/local/lib/libxed.so
perf top: Display the LBR stats in callchain entry
perf stat: Handle different PMU names with common prefix
perf record: Support weak groups
perf evlist: Move perf_evsel__reset_weak_group into evlist
perf augmented_syscalls: Start collecting pathnames in the BPF program
perf trace: Fix setting of augmented payload when using eBPF + raw_syscalls
perf trace: When augmenting raw_syscalls plug raw_syscalls:sys_exit too
perf examples bpf: Start augmenting raw_syscalls:sys_{start,exit}
tools headers barrier: Fix arm64 tools build failure wrt smp_load_{acquire,release}

<h3>Points to note:</h3>
|
||||
<ul>
|
||||
<li>The top level is a command name (comm)</li>
|
||||
<li>The next level is a thread (pid:tid)</li>
|
||||
<li>Subsequent levels are functions</li>
|
||||
<li>'Count' is the number of calls</li>
|
||||
<li>'Time' is the elapsed time until the function returns</li>
|
||||
<li>Percentages are relative to the level above</li>
|
||||
<li>'Branch Count' is the total number of branches for that function and all functions that it calls
|
||||
</ul>
|
||||
<h3>Find</h3>
|
||||
Ctrl-F displays a Find bar which finds function names by either an exact match or a pattern match.
|
||||
The pattern matching symbols are ? for any character and * for zero or more characters.
|
||||
<h2 id=allbranches>1.2 All branches</h2>
|
||||
The All branches report displays all branches in chronological order.
|
||||
Not all data is fetched immediately. More records can be fetched using the Fetch bar provided.
|
||||
<h3>Disassembly</h3>
|
||||
Open a branch to display disassembly. This only works if:
|
||||
<ol>
|
||||
<li>The disassembler is available. Currently, only Intel XED is supported - see <a href=#xed>Intel XED Setup</a></li>
|
||||
<li>The object code is available. Currently, only the perf build ID cache is searched for object code.
|
||||
The default directory ~/.debug can be overridden by setting environment variable PERF_BUILDID_DIR.
|
||||
One exception is kcore where the DSO long name is used (refer dsos_view on the Tables menu),
|
||||
or alternatively, set environment variable PERF_KCORE to the kcore file name.</li>
|
||||
</ol>
|
||||
<h4 id=xed>Intel XED Setup</h4>
|
||||
To use Intel XED, libxed.so must be present. To build and install libxed.so:
|
||||
<pre>
|
||||
git clone https://github.com/intelxed/mbuild.git mbuild
|
||||
git clone https://github.com/intelxed/xed
|
||||
cd xed
|
||||
./mfile.py --share
|
||||
sudo ./mfile.py --prefix=/usr/local install
|
||||
sudo ldconfig
|
||||
</pre>
|
||||
<h3>Find</h3>
|
||||
Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match.
|
||||
Refer to Python documentation for the regular expression syntax.
|
||||
All columns are searched, but only currently fetched rows are searched.
|
||||
<h2 id=selectedbranches>1.3 Selected branches</h2>
|
||||
This is the same as the <a href=#allbranches>All branches</a> report but with the data reduced
|
||||
by various selection criteria. A dialog box displays available criteria which are AND'ed together.
|
||||
<h3>1.3.1 Time ranges</h3>
|
||||
The time ranges hint text shows the total time range. Relative time ranges can also be entered in
|
||||
ms, us or ns. Also, negative values are relative to the end of trace. Examples:
|
||||
<pre>
|
||||
81073085947329-81073085958238 From 81073085947329 to 81073085958238
|
||||
100us-200us From 100us to 200us
|
||||
10ms- From 10ms to the end
|
||||
-100ns The first 100ns
|
||||
-10ms- The last 10ms
|
||||
</pre>
|
||||
N.B. Due to the granularity of timestamps, there could be no branches in any given time range.
|
||||
<h1 id=tables>2. Tables</h1>
|
||||
The Tables menu shows all tables and views in the database. Most tables have an associated view
|
||||
which displays the information in a more friendly way. Not all data for large tables is fetched
|
||||
immediately. More records can be fetched using the Fetch bar provided. Columns can be sorted,
|
||||
but that can be slow for large tables.
|
||||
<p>There are also tables of database meta-information.
|
||||
For SQLite3 databases, the sqlite_master table is included.
|
||||
For PostgreSQL databases, information_schema.tables/views/columns are included.
|
||||
<h3>Find</h3>
|
||||
Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match.
|
||||
Refer to Python documentation for the regular expression syntax.
|
||||
All columns are searched, but only currently fetched rows are searched.
|
||||
<p>N.B. Results are found in id order, so if the table is re-ordered, find-next and find-previous
|
||||
will go to the next/previous result in id order, instead of display order.
