+Subject: [PATCH] perf tools: Add Python 3 support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Added Python 3 support while keeping Python 2.7 compatibility.
+
+Committer notes:
+
+This doesn't make it to auto detect python 3, one has to explicitely ask
+it to build with python 3 devel files, here are the instructions
+provided by Jaroslav:
+
+ ---
+  $ cp -a tools/perf tools/python3-perf
+  $ make V=1 prefix=/usr -C tools/perf PYTHON=/usr/bin/python2 all
+  $ make V=1 prefix=/usr -C tools/python3-perf PYTHON=/usr/bin/python3 all
+  $ make V=1 prefix=/usr -C tools/python3-perf PYTHON=/usr/bin/python3 DESTDIR=%{buildroot} install-python_ext
+  $ make V=1 prefix=/usr -C tools/perf PYTHON=/usr/bin/python2 DESTDIR=%{buildroot} install-python_ext
+ ---
+
+We need to make this automatic, just like the existing tests for checking if
+the python2 devel files are in place, allowing the build with python3 if
+available, fallbacking to python2 and then just disabling it if none are
+available.
+
+So, using the PYTHON variable to build it using O= we get:
+
+Before this patch:
+
+  $ rpm -q python3 python3-devel
+  python3-3.6.4-7.fc27.x86_64
+  python3-devel-3.6.4-7.fc27.x86_64
+  $ rm -rf /tmp/build/perf/ ; mkdir -p /tmp/build/perf ; make O=/tmp/build/perf PYTHON=/usr/bin/python3 -C tools/perf install-bin
+  make: Entering directory '/home/acme/git/linux/tools/perf'
+  <SNIP>
+  Makefile.config:670: Python 3 is not yet supported; please set
+  Makefile.config:671: PYTHON and/or PYTHON_CONFIG appropriately.
+  Makefile.config:672: If you also have Python 2 installed, then
+  Makefile.config:673: try something like:
+  Makefile.config:674:
+  Makefile.config:675:   make PYTHON=python2
+  Makefile.config:676:
+  Makefile.config:677: Otherwise, disable Python support entirely:
+  Makefile.config:678:
+  Makefile.config:679:   make NO_LIBPYTHON=1
+  Makefile.config:680:
+  Makefile.config:681: *** .  Stop.
+  make[1]: *** [Makefile.perf:212: sub-make] Error 2
+  make: *** [Makefile:110: install-bin] Error 2
+  make: Leaving directory '/home/acme/git/linux/tools/perf'
+  $
+
+After:
+
+  $ make O=/tmp/build/perf PYTHON=python3 -C tools/perf install-bin
+  $ ldd ~/bin/perf | grep python
+	libpython3.6m.so.1.0 => /lib64/libpython3.6m.so.1.0 (0x00007f58a31e8000)
+  $ rpm -qf /lib64/libpython3.6m.so.1.0
+  python3-libs-3.6.4-7.fc27.x86_64
+  $
+
+Now verify that when using the binding the right ELF file is loaded,
+using perf trace:
+
+  $ perf trace -e open* perf test python
+     0.051 ( 0.016 ms): perf/3927 openat(dfd: CWD, filename: /etc/ld.so.cache, flags: CLOEXEC           ) = 3
+<SNIP>
+  18: 'import perf' in python                               :
+     8.849 ( 0.013 ms): sh/3929 openat(dfd: CWD, filename: /etc/ld.so.cache, flags: CLOEXEC           ) = 3
+<SNIP>
+    25.572 ( 0.008 ms): python3/3931 openat(dfd: CWD, filename: /tmp/build/perf/python/perf.cpython-36m-x86_64-linux-gnu.so, flags: CLOEXEC) = 3
+<SNIP>
+ Ok
+<SNIP>
+  $
+
+And using tools/perf/python/twatch.py, to show PERF_RECORD_ metaevents:
+
+  $ python3 tools/perf/python/twatch.py
