From: Arnaldo Carvalho de Melo These types of jumps were confusing the annotate browser: entry_SYSCALL_64 /lib/modules/4.16.0-rc5-00086-gdf09348f78dc/build/vmlinux entry_SYSCALL_64 /lib/modules/4.16.0-rc5-00086-gdf09348f78dc/build/vmlinux Percent│81a00020: swapgs

[PATCH 39/44] perf annotate: Mark jumps to outher functions with the call arrow

From: Arnaldo Carvalho de Melo Things like this in _cpp_lex_token (gcc's cc1 program): cpp_named_operator2name@@Base+0xa72 Point to a place that is after the cpp_named_operator2name boundaries, i.e. in the ELF symbol table for cc1 cpp_named_operator2name is marked as being 32-bytes long,

[PATCH 42/44] perf annotate: Support jumping from one function to another

From: Arnaldo Carvalho de Melo For instance: entry_SYSCALL_64 /lib/modules/4.16.0-rc5-00086-gdf09348f78dc/build/vmlinux 5.50 │ → callq do_syscall_64 14.56 │ mov0x58(%rsp),%rcx 7.44 │ mov0x80(%rsp),%r11 0.32 │ cmp%rcx,%r11 │ → jne

[PATCH 38/44] perf annotate: Pass function descriptor to its instruction parsing routines

From: Arnaldo Carvalho de Melo We need that to figure out if jumps have targets in a different function. E.g. _cpp_lex_token(), in /usr/libexec/gcc/x86_64-redhat-linux/5.3.1/cc1 has a line like this: jnec469be Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc:

[PATCH 35/44] perf report: Introduce --ignore-vmlinux command line option

From: Arnaldo Carvalho de Melo We've had this in 'perf top' for quite a while, useful if one wishes to force using /proc/kcore to do annotation using the patched kernel instead of the ELF image it started from, aka vmlinux. Cc: Adrian Hunter Cc: Andi Kleen Cc: David Ahern Cc: Jin Yao Cc:

[PATCH 36/44] perf annotate browser: Add 'P' hotkey to dump annotation to file

From: Arnaldo Carvalho de Melo Just like we have in the histograms browser used as the main screen for 'perf top --tui' and 'perf report --tui', to print the current annotation to a file with a named composed by the symbol name and the ".annotation" suffix. Here is one example

From: Arnaldo Carvalho de Melo Just like we have in the histograms browser used as the main screen for 'perf top --tui' and 'perf report --tui', to print the current annotation to a file with a named composed by the symbol name and the ".annotation" suffix. Here is one example of pressing 'A'

[PATCH 30/44] perf annotate: Introduce the --stdio2 output mode

From: Arnaldo Carvalho de Melo This uses the TUI augmented formatting routines, modulo interactivity. # perf annotate --ignore-vmlinux --stdio2 _raw_spin_lock_irqsave _raw_spin_lock_irqsave() /proc/kcore Event: cycles:ppp Percent Disassembly of section

[PATCH 29/44] perf annotate: Introduce annotation_line__filter()

From: Arnaldo Carvalho de Melo Out of the TUI logic that allows toggling the presentation of source code lines. Will be used in the upcoming --stdio2 mode. Cc: Adrian Hunter Cc: Andi Kleen Cc: David Ahern Cc:

[PATCH 18/44] perf annotate: Move nr_{asm_}entries to struct annotation

From: Arnaldo Carvalho de Melo More non-TUI stuff. Cc: Adrian Hunter Cc: Andi Kleen Cc: David Ahern Cc: Jin Yao Cc: Jiri Olsa Cc: Namhyung Kim

[PATCH 31/44] perf annotate: Move the default annotate options to the library

From: Arnaldo Carvalho de Melo One more thing that goes from the TUI code to be used more widely, for instance it'll affect the default options used by: perf annotate --stdio2 Cc: Adrian Hunter Cc: Andi Kleen Cc: David Ahern

[PATCH 27/44] perf annotate: Finish the generalization of annotate_browser__write()

From: Arnaldo Carvalho de Melo We pass some more callbacks and all of annotate_browser__write() seems to be free of TUI code (except for some arrow constants, will fix). Cc: Adrian Hunter Cc: Andi Kleen Cc: David Ahern
