rcar-gen3: linux-renesas: Fix Perf build failure with 4.14 kernel
OE-Core started using Python3 for perf module. But older kernel such as 4.14 does not have support for python3. This causes build failure as follows: | Makefile.config:391: DWARF support is off, BPF prologue is disabled | Makefile.config:588: Missing perl devel files. Disabling perl scripting support, please install perl-ExtUtils-Embed/libperl-dev | Makefile.config:626: Python 3 is not yet supported; please set | Makefile.config:627: PYTHON and/or PYTHON_CONFIG appropriately. | Makefile.config:628: If you also have Python 2 installed, then | Makefile.config:629: try something like: Backported python3 support, as a suggestion here: https://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/meta/recipes-kernel/perf?id=92469aad50b623afa423c19d82ed2e3c667c5e6a This fix was backported from: https://lists.yoctoproject.org/pipermail/meta-intel/2019-September/006191.html Signed-off-by: Khang Nguyen <khang.nguyen.xw@renesas.com> Signed-off-by: Takamitsu Honda <takamitsu.honda.pv@renesas.com> Change-Id: Ieaad61fb9bd4888e6226c8e00d4807f738cc0b55

+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
