tools build: Remove feature-libslang-include-subdir

2025-10-03T19:49:51+00:00

Added in commit cbefd24f0aee3a5d ("tools build: Add test to check if slang.h is in /usr/include/slang/") this feature was to fix build support on now unsupported versions of RHEL 5 and 6. As 6 years has passed let's remove the workaround.

perf annotate: Fix title line after return from call

2025-09-09T18:12:33+00:00

The second title line which shows symbol and DSO name is broken after moving to another function at 'callq' instruction. The ui_browser__show_title() is used for the first line which shows global sample count and event name so it doesn't change across the functions. What it needs after processing 'call' instruction is to update the second line onlly. Add a comment and call appropriate function. You can verify the change by pressing ENTER on a 'call' instruction and then ESC.

perf annotate: Factor out annotate_browser__show_function_title()

2025-09-09T18:12:15+00:00

It'll be used in other places. Signed-off-by: Namhyung Kim Cc: Adrian Hunter Cc: Ian Rogers Cc: Ingo Molnar Cc: Jiri Olsa Cc: Kan Liang Cc: Peter Zijlstra Signed-off-by: Arnaldo Carvalho de Melo

perf annotate: Fix signature of annotate_browser__show()

2025-09-09T18:05:23+00:00

According to convention, the first argument should be 'struct annotate_browser' instead of 'struct ui_brwoser'.

perf annotate: Use a hashmap to save type data

2025-09-02T20:14:00+00:00

It can slowdown annotation browser if objdump is processing large DWARF data. Let's add a hashmap to save the data type info for each line. Note that this is needed for TUI only because stdio only processes each line once. TUI will display the same line whenever it refreshes the screen.

perf annotate: Add dso__debuginfo() helper

2025-08-28T15:35:42+00:00

It'd be great if it can get the correct debug information using DSO build-Id not just the path name. Instead of adding new callsites of debuginfo__new(), let's add dso__debuginfo() which can hide the access using the pathname and help the future conversion.

perf annotate: Show warning when debuginfo is not available

2025-08-28T15:35:12+00:00

When user requests data-type annotation but no DWARF info is available, show a warning message about it. Warning: DWARF debuginfo not found. Data-type in this DSO will not be displayed. Please make sure to have debug information. Press any key...

perf annotate: Add 'T' hot key to toggle data type display

2025-08-28T15:33:18+00:00

Support data type display with a key press so that users can toggle the output dynamically on TUI. Also display "[Type]" in the title line if it's enabled.

perf annotate: Add --code-with-type support for TUI

2025-08-28T15:33:08+00:00

Until now, the --code-with-type option is available only on stdio. But it was an artifical limitation because of an implemention issue. Implement the same logic in annotation_line__write() for stdio2/TUI and remove the limitation and update the man page.

perf annotate: Pass annotation_print_data to annotation_line__write()

It will be used for data type display later.
