2023-06-12perf thread: Add accessor functions for threadIan Rogers1-2/+2
Using accessors will make it easier to add reference count checking in later patches. Committer notes: thread->nsinfo wasn't wrapped as it is used together with nsinfo__zput(), where does a trick to set the field with a refcount being dropped to NULL, and that doesn't work well with using thread__nsinfo(thread), that loses the &thread->nsinfo pointer. When refcount checking is added to 'struct thread', later in this series, nsinfo__zput(RC_CHK_ACCESS(thread)->nsinfo) will be used to check the thread pointer.

2023-04-04perf map: Add accessor for dsoIan Rogers1-2/+4
Later changes will add reference count checking for struct map, with dso being the most frequently accessed variable. Add an accessor so that the reference count check is only necessary in one place. Additional changes: - add a dso variable to avoid repeated map__dso calls. - in builtin-mem.c dump_raw_samples, code only partially tested for dso == NULL. Make the possibility of NULL consistent. - in thread.c thread__memcpy fix use of spaces and use tabs.

2023-03-15perf script: Fix Python support when no libtraceeventAdrian Hunter1-0/+4
Python scripting can be used without libtraceevent. In particular, scripting for Intel PT does not use tracepoints, and so does not need libtraceevent support. Alter the build and employ conditional compilation to allow Python scripting without libtraceevent. Example: Before: $ ldd `which perf` | grep -i python $ ldd `which perf` | grep -i libtraceevent $ perf record -e intel_pt//u uname Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.031 MB perf.data ] $ perf script intel-pt-events.py |& head -3 Error: Couldn't find script `intel-pt-events.py' See perf script -l for available scripts. After: $ ldd `which perf` | grep -i python libpython3.10.so.1.0 => /lib/x86_64-linux-gnu/libpython3.10.so.1.0 (0x00007f4bac400000) $ ldd `which perf` | grep -i libtraceevent $ perf script intel-pt-events.py | head Intel PT Branch Trace, Power Events, Event Trace and PTWRITE Switch In 8021/8021 [000] 11234.097713404 0/0 perf-exec 8021/8021 [000] 11234.098041726 psb offset: 0x0 0 [unknown] ([unknown]) perf-exec 8021/8021 [000] 11234.098041726 cbr 45 freq: 4505 MHz (161%) 0 [unknown] ([unknown]) uname 8021/8021 [000] 11234.098082170 branches:uH tr strt 0 [unknown] ([unknown]) => 7f3a8b9422b0 _start+0x0 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) uname 8021/8021 [000] 11234.098082379 branches:uH tr end 7f3a8b9422b0 _start+0x0 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) => 0 [unknown] ([unknown]) uname 8021/8021 [000] 11234.098083629 branches:uH tr strt 0 [unknown] ([unknown]) => 7f3a8b9422b0 _start+0x0 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) uname 8021/8021 [000] 11234.098083629 branches:uH call 7f3a8b9422b3 _start+0x3 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) => 7f3a8b943050 _dl_start+0x0 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) uname 8021/8021 [000] 11234.098083837 branches:uH tr end 7f3a8b943060 _dl_start+0x10 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) => 0 [unknown] ([unknown]) IPC: 0.01 (9/938) uname 8021/8021 [000] 11234.098084670 branches:uH tr strt 0 [unknown] ([unknown]) => 7f3a8b943060 _dl_start+0x10 (/usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2) Fixes: 378ef0f5d9d7f465 ("perf build: Use libtraceevent from the system") Signed-off-by: Adrian Hunter <[email protected]> Cc: Ian Rogers <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Namhyung Kim <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>

2018-02-19perf tools: Add Python 3 supportJaroslav Škarvada1-3/+31
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.
