Make process_attr() respect -F-ip, noting also that the condition in process_attr() (callchain_param.record_mode != CALLCHAIN_NONE) is always true so test the sample type directly. Example: Before: $ perf record -e intel_pt//u uname Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.033 MB perf.data ] $ perf script --call-trace | head -5 uname 30992 [006] 41758.313696574: cbr: 42 freq: 4219 MHz (156%) 0 [unknown] ([unknown] ) uname 30992 [006] 41758.313696907: _start 7f71792c4100 _start+0x0 (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) uname 30992 [006] 41758.313699574: _dl_start 7f71792c4103 _start+0x3 (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) uname 30992 [006] 41758.313699907: _dl_start 7f71792c4e18 _dl_start+0x28 (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) uname 30992 [006] 41758.313701574: _dl_start 7f71792c5128 _dl_start+0x338 (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) After: $ perf script --call-trace | head -5 uname 30992 [006] 41758.313696574: cbr: 42 freq: 4219 MHz (156%) uname 30992 [006] 41758.313696907: (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) _start uname 30992 [006] 41758.313699574: (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) _dl_start uname 30992 [006] 41758.313699907: (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) _dl_start uname 30992 [006] 41758.313701574: (/usr/lib/x86_64-linux-gnu/ld-2.31.so ) _dl_start Fixes: f288e8e1aa4f ("perf script: Enable IP fields for callchains") Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lore.kernel.org/lkml/20200527180250.16723-1-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
