| H A D | hists.h | 7fa46cbf Thu Nov 07 01:47:19 CST 2019 Jin Yao <yao.jin@linux.intel.com> perf report: Sort by sampled cycles percent per block for tui
Previous patch has implemented a new option "--total-cycles". But only
stdio mode is supported.
This patch supports the tui mode and support '--percent-limit'.
For example,
perf record -b ./div
perf report --total-cycles --percent-limit 1

--------------------------------------------------
v7:
---
1. Since we have used use_browser in report__browse_block_hists
to support stdio mode, now we also add supporting for tui.
2. Move block tui browser code from ui/browsers/hists.c
to block-info.c.
v6:
---
Create report__tui_browse_block_hists in block-info.c
(codes are moved from builtin-report.c).
v5:
---
Fix a crash issue when running perf report without
'--total-cycles'. The issue is because the internal flag
is renamed from 'total_cycles' to 'total_cycles_mode' in
previous patch but this patch still uses 'total_cycles'
to check if the '--total-cycles' option is enabled, which
causes the code to be inconsistent.
v4:
---
Since the block collection is moved out of printing in
previous patch, this patch is updated accordingly for
tui supporting.
v3:
---
Minor change since the function name is changed:
block_total_cycles_percent -> block_info__total_cycles_percent

v6:
---
Create report__tui_browse_block_hists in block-info.c
(codes are moved from builtin-report.c).
v5:
---
Fix a crash issue when running perf report without
'--total-cycles'. The issue is because the internal flag
is renamed from 'total_cycles' to 'total_cycles_mode' in
previous patch but this patch still uses 'total_cycles'
to check if the '--total-cycles' option is enabled, which
causes the code to be inconsistent.
v4:
---
Since the block collection is moved out of printing in
previous patch, this patch is updated accordingly for
tui supporting.
v3:
---
Minor change since the function name is changed:
block_total_cycles_percent -> block_info__total_cycles_percent

Previous patch has implemented a new option "--total-cycles". But only
stdio mode is supported.
This patch supports the tui mode and support '--percent-limit'.
For example,
perf record -b ./div
perf report --total-cycles --percent-limit 1

to support stdio mode, now we also add supporting for tui.
2. Move block tui browser code from ui/browsers/hists.c
