2015-01-16perf tools: Fix building error in x86_64 when dwarf unwind is onNamhyung Kim
When build with 'make ARCH=x86' and dwarf unwind is on, there is a compiling error: CC /home/wn/perf/arch/x86/util/unwind-libdw.o CC /home/wn/perf/arch/x86/tests/regs_load.o arch/x86/tests/regs_load.S: Assembler messages: arch/x86/tests/regs_load.S:65: Error: operand type mismatch for `push' arch/x86/tests/regs_load.S:72: Error: operand type mismatch for `pop' make[1]: *** [/home/wn/perf/arch/x86/tests/regs_load.o] Error 1 make[1]: INTERNAL: Exiting with 25 jobserver tokens available; should be 24! make: *** [all] Error 2 ... Which is caused by incorrectly undefine macro HAVE_ARCH_X86_64_SUPPORT. 'config/Makefile.arch' tests __x86_64__ only when 'ARCH=x86_64'. However, when building x86_64 kernel, ARCH=x86 is valid and commonly used. Build systems, such as yocto, uses x86_64 compiler with 'ARCH=x86' to build x86_64 perf, which causes mismatching. As __LP64__ is defined for x86_64 as well, we can consolidate the __x86_64__ check to the __LP64__ check and get rid of the IS_X86_64 IMHO. (This patch is made by Namhyung Kim when replying my v1 patch: https://lkml.org/lkml/2015/1/7/17 I modified the code to remove dependency on RAW_ARCH: https://lkml.org/lkml/2015/1/7/865 Namhyung Kim didn't provide his SOB in his original email.

2014-10-29perf tools: Add facility to export data in database-friendly wayAdrian Hunter
This patch introduces an abstraction for exporting sample data in a database-friendly way. The abstraction does not implement the actual output. A subsequent patch takes this facility into use for extending the script interface. The abstraction is needed because static data like symbols, dsos, comms etc need to be exported only once. That means allocating them a unique identifier and recording it on each structure. The member 'db_id' is used for that. 'db_id' is just a 64-bit sequence number. Exporting centres around the db_export__sample() function which exports the associated data structures if they have not yet been allocated a db_id.

2014-09-17perf tools: Add perf-with-kcore scriptAdrian Hunter
Decoding an Intel PT trace of the kernel requires an accurate kernel object image. This is provided by making a copy of kcore. However the copy needs to be made under the same conditions as the original recording, and then it needs to be associated with the perf.data file. The perf-with-kcore script does that. The script also checks the permissions on the buildid cache and can be used to fix them. That is needed for distributions where root does not have a home directory and consequently writes to the same buildid cache as the user, resulting in cached files that the user does not have access to. Example: $ ./perf-with-kcore Usage: perf-with-kcore <perf sub-command> <perf.data directory> [<sub-command options> [ -- <workload>]] <perf sub-command> can be record, script, report or inject or: perf-with-kcore fix_buildid_cache_permissions $ ./perf-with-kcore record pt_uname -e intel_pt// -- uname Recording Using /home/ahunter/bin/perf perf version 3.15.rc3.g4549ba /home/ahunter/bin/perf record -o pt_uname/perf.data -e intel_pt// -- uname Linux [ perf record: Woken up 3 times to write data ] [ perf record: Captured and wrote 0.023 MB pt_uname/perf.data ] Copying kcore [sudo] password for ahunter: Done $ tools/perf/perf-with-kcore.sh script pt_uname | head Using /home/ahunter/bin/perf perf version 3.15.rc3.g4549ba /home/ahunter/bin/perf script -i pt_uname/perf.data --kallsyms=pt_uname/kcore_dir/kallsyms swapper 0 [002] 161533.969666: sched:sched_switch: swapper/2:0 [120] R ==> perf:11316 [120] :11315 11315 [003] 161533.969704: sched:sched_switch: perf:11315 [120] S ==> swapper/3:0 [120] :11316 11316 [002] 161533.969783: sched:sched_switch: perf:11316 [120] R ==> migration/2:33 [0] :33 33 [002] 161533.969791: sched:sched_switch: migration/2:33 [0] S ==> swapper/2:0 [120] swapper 0 [003] 161533.969792: sched:sched_switch: swapper/3:0 [120] R ==> perf:11316 [120] :11316 11316 [003] 161533.970062: branches: 0 [unknown] ([unknown]) => ffffffff810532fa native_write_msr_safe ([kernel.kallsyms]) :11316 11316 [003] 161533.970062: branches: ffffffff810532fd native_write_msr_safe ([kernel.kallsyms]) => ffffffff81035b31 pt_config_start ([kernel.kallsyms]) Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/1406786474-9306-30-git-send-email-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2014-07-17perf tools: Allow TSC conversion on any archAdrian Hunter
It is possible to record a perf.data file on one architecture and process it on another. Consequently, TSC conversion functions need to be moved out of the arch directory.

2014-07-16perf kvm: Move arch specific code into arch/Alexander Yarygin
Parts of a 'perf kvm stat' code make sense only for x86. Let's move this code into the arch/x86/kvm-stat.c file and add util/kvm-stat.h for generic structure definitions. Add a global array 'kvm_reg_events_ops' for accessing the arch-specific 'kvm_events_ops' from generic code. Since the several global arrays (i.e. 'kvm_events_tp') have been moved to arch/*, we can not know their sizes and use them directly in builtin-kvm.c. This patch fixes that problem by adding trimming NULL element to each array and changing the behavior of their handlers in generic code.

2014-06-03perf tools: Fix 'make help' message errorJianyu Zhan
Currently 'make help' message has such hint: use "make prefix=<path> <install target>" to install to a particular path like make prefix=/usr/local install install-doc But this is misleading, when I specify "prefix=/usr/local", it has got no respect at all. This is because that, "DESTDIR" is considered first. In this case, "DESTDIR" has an empty value, so "prefix" is honored. However, "prefix" is unconditionally assigned to $HOME, regardless of what it is set to from command line. So our "prefix" setting got no respect and the actual destination falls back to $HOME. This patch fixes this issue and corrects the help message.
