Gather output and sort lists under struct perf_hpp_list, so we could have multiple instancies of sort/output format entries. Replacing current perf_hpp__list and perf_hpp__sort_list lists with single perf_hpp_list instance. Signed-off-by:

With multiple list holding format entries, we need the support properly releasing format output/sort fields. Signed-off-by:
-
Jiri Olsa authored
Those functions are no longer needed. They operate over perf_hpp__format array which is now used only as template for dynamic entries. Signed-off-by:

Jiri Olsa authored
Currently we use static output fields, because we have single global list of all sort/output fields. We will add hists specific sort and output lists in following patches, so we need all format entries to be dynamically allocated. Adding support to allocate output sort field. Signed-off-by:

The ui initialization changes hpp format callbacks, based on the used browser. Thus we need this init being processed before setup_sorting. Replica of a patch by Jiri for 'perf report'.

Now that we have the 'equal' method implemented for hpp format entries we can ease up the logic in the following functions and make them generic wrt comparing format entries: perf_hpp__setup_output_field perf_hpp__append_sort_keys Signed-off-by:

To easily compare format entries and make it available for all kinds of format entries. Signed-off-by:

Jiri Olsa authored
We are going to add dynamic hpp format fields, so we need to make the 'len' change for the format itself, not in the perf_hpp__format template. Signed-off-by:

Jiri Olsa authored
Currently there's no way of comparing hpp format entries, which is needed in following patches. Adding _idx fields into struct perf_hpp_fmt to recognize and be able to compare hpp format entries. Signed-off-by:

Adding evsel specific function to sort hists_evsel based hists. The hists__output_resort can be now used to sort common hists object. Signed-off-by:
-
Jiri Olsa authored
Currently hists__output_resort() depends on hists based on hists_evsel struct, but we need to be able to sort common hists as well. Cutting out the sorting base sorting code into output_resort function, so it can be reused in following patch. Signed-off-by:

When all callchains of a hist entry is percent-limited, do not add a blank line at the end. It makes the entry look like it doesn't have callchains. Reported-and-Tested-by:

When there's only a single callchain, perf doesn't print its percentage in front of the symbols. This is because it assumes that the percentage is same as parents. But if a percent limit is applied, it's possible that there are actually a couple of child nodes but only one of them is shown. In this case it should display the percent to prevent misunderstanding of its percentage is same as the parent's. For example, let's see the following callchain. $ perf report --no-children --percent-limit 0.01 --tui ... - 0.06% sleep [kernel.vmlinux] [k] kmem_cache_alloc_trace kmem_cache_alloc_trace - perf_event_mmap - 0.04% mmap_region do_mmap_pgoff - vm_mmap_pgoff + 0.02% sys_mmap_pgoff + 0.02% vm_mmap + 0.02% mprotect_fixup Current code omits the percent if 'mmap_region' becomes the only node when percent limit is set to 0.03%, its percent is not 0.06% but users will assume it incorrectly. Before: $ perf report --no-children --percent-limit 0.03 --tui ... 0.06% sleep [kernel.vmlinux] [k] kmem_cache_alloc_trace kmem_cache_alloc_trace - perf_event_mmap - mmap_region do_mmap_pgoff vm_mmap_pgoff After: $ perf report --no-children --percent-limit 0.03 --tui ... 0.06% sleep [kernel.vmlinux] [k] kmem_cache_alloc_trace kmem_cache_alloc_trace - perf_event_mmap - 0.04% mmap_region do_mmap_pgoff vm_mmap_pgoff Signed-off-by: -

The commit 8c430a34 ("perf hists browser: Support folded callchains") missed to update hist_browser__dump() so it always shows graph-style callchains regardless of current setting. To fix that, factor out callchain printing code and rename the existing function which prints graph-style callchain. Signed-off-by:

Currently the hist entry addition path doesn't update total_period of hists and it's calculated during 'resort' path. But the resort path needs to know the total period before doing its job because it's used for calculating percent limit of callchains in hist entries. So this patch update the total period during the addition path. It makes the percent limit of callchains working (again). Signed-off-by:

Namhyung Kim authored
The total period should be get using hists__total_period() since it takes filtered entries into account. In addition, if callchain mode is 'fractal', the total period should be the entry's period. Signed-off-by:
