[PATCH v6 0/4] perf: Refactor the block info implementation

[PATCH v6 0/4] perf: Refactor the block info implementation

[Jin Yao]

This patch series refactors the block info functionalities to let them
be used by other builtins and allow setting the output fmts flexibly.

It also supports the 'Sampled Cycles%' and 'Avg Cycles%' printed in
colors.

 v6:
 ---
 Use __block_info__cmp to replace block_pair_cmp according to Arnaldo's
 suggestions. Fix some issues found in block_info__cmp.

 New patches:
 ------------
 perf util: Fix wrong block address comparison in block_info__cmp
 perf util: Use __block_info__cmp to replace block_pair_cmp

 Unchanged patches:
 ------------------
 perf util: Flexible to set block info output formats
 perf util: Support color ops to print block percents in color

 v5:
 ---
 Only change the patch "perf util: Flexible to set block info output formats".
 Other patches are not changed.

Jin Yao (4):
  perf util: Fix wrong block address comparison in block_info__cmp
  perf util: Use __block_info__cmp to replace block_pair_cmp
  perf util: Flexible to set block info output formats

[PATCH v6 1/4] perf util: Fix wrong block address comparison in block_info__cmp

[Jin Yao]

Commit 6041441870ab ("perf block: Cleanup and refactor block info
functions") introduces a function block_info__cmp, which compares
two blocks.

But the issues are:

1. It should return the strcmp cmp value only if it's not 0.

2. When symbol names are matched, we need to compare the addresses
   of blocks further. But it wrongly uses the symbol addresses for
   comparison.

3. If the syms are both NULL, we can't consider these two blocks are
   matched.

This patch fixes above 3 issues.

functions")

[PATCH v6 2/4] perf util: Use __block_info__cmp to replace block_pair_cmp

[Jin Yao]

perf-diff uses block_pair_cmp to compare two blocks. The
block_info__cmp has the similar functionality and it's
a bit more complete.

This patch removes the block_pair_cmp and use __block_info__cmp
instead. The __block_info__cmp is wrapped by block_info__cmp
and it doesn't receive perf_hpp_fmt parameter.

[PATCH v6 3/4] perf util: Flexible to set block info output formats

[Jin Yao]

Currently we use a predefined array to set the
block info output formats, it's fixed and inflexible.

This patch adds two parameters "block_hpps" and "nr_hpps"
in block_info__create_report and other static functions,
in order to let user decide which columns to report and
with specified report ordering. It should be more flexible.

Buffers will be allocated to contain the new fmts, of course,
we need to release them before perf exits.

 v6:
 ---
 No change.

 v5:
 ---
 Don't need to call hists__delete_entries() after printing the
 block hists, because we will release the block hists in
 block_info__free_report().

 v4:
 ---
 Keep fmts in struct block_report as an array, instead of
 allocaing it. That's we don't need the release code.

 v3:
 ---
 No change.

 v2:
 ---
 New patch created in v2.

perf block-info: Allow selecting which columns to report and its order

Currently we use a predefined array to set the block info output
formats, it's fixed and inflexible.

This patch adds two parameters "block_hpps" and "nr_hpps" in
block_info__create_report and other static functions, in order to let
user decide which columns to report and with specified report ordering.
It should be more flexible.

Buffers will be allocated to contain the new fmts, of course, we need to
release them before perf exits.

[PATCH v6 4/4] perf util: Support color ops to print block percents in color

[Jin Yao]

It would be nice to print the block percents with colors.

This patch supports the 'Sampled Cycles%' and 'Avg Cycles%'
printed in colors.

For example,

perf record -b ...
perf report --total-cycles or perf report --total-cycles --stdio

percent > 5%, colored in red
percent > 0.5%, colored in green
percent < 0.5%, default color

 v3/v4/v5/v6:

 No change

 v2:

Thanks, tested the coloring, all works as advertised, thanks, applied to
perf/core, should be in git.kernel.org soon.

For example,
