The column width of dynamic entries is updated when comparing hist entries. However some unique entries can miss the chance to update. So move the update to output resort stage to make sure every entry will get called before display. To do that, abuse ->sort callback to update the width when the third argument is NULL. When resorting entries in normal path, it never be NULL so it should be fine IMHO.

When dynamic sort key is used it might not show pretty printed output. This is because the trace output was not set only for the first dynamic sort key. During hierarchy_insert_entry() it missed to pass the trace_output to dynamic entries. Also even if it did, only first entry will have it. Subsequent entries might set it during collapsing stage but it's not guaranteed.

The dynamic entries are right-aligned unlike other entries since it usually has numeric value. But for the hierarchy mode, left alignment is more appropriate IMHO. Also trim spaces on the left so that we can easily identify the hierarchy.

When dynamic entries are used in the hierarchy mode with multiple events, the output might not be aligned properly. In the hierarchy mode, the each sort column is indented using total number of sort keys. So it keeps track of number of sort keys when adding them. However a dynamic sort key can be added more than once when multiple events have same field names. This results in unnecessarily long indentation in the output. For example perf kmem records following events: $ perf evlist --trace-fields -i perf.data.kmem kmem:kmalloc: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags kmem:kmalloc_node: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags,node kmem:kfree: trace_fields: call_site,ptr kmem:kmem_cache_alloc: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags kmem:kmem_cache_alloc_node: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags,node kmem:kmem_cache_free: trace_fields: call_site,ptr kmem:mm_page_alloc: trace_fields: page,order,gfp_flags,migratetype kmem:mm_page_free: trace_fields: page,order As you can see, many field names shared between kmem events. So adding 'ptr' dynamic sort key alone will set nr_sort_keys to 6. And this adds many unnecessary spaces between columns. Before: $ perf report -i perf.data.kmem --hierarchy -s ptr -g none --stdio ... # Overhead ptr # ....................... ................................... # 99.89% 0xffff8803ffb79720 0.06% 0xffff8803d228a000 0.03% 0xffff8803f7678f00 0.00% 0xffff880401dc5280 0.00% 0xffff880406172380 0.00% 0xffff8803ffac3a00 0.00% 0xffff8803ffac1600 After: # Overhead ptr # ........ .................... # 99.89% 0xffff8803ffb79720 0.06% 0xffff8803d228a000 0.03% 0xffff8803f7678f00 0.00% 0xffff880401dc5280 0.00% 0xffff880406172380 0.00% 0xffff8803ffac3a00 0.00% 0xffff8803ffac1600 Signed-off-by: -

The hists__overhead_width() is to calculate width occupied by the overhead (and others) columns before the sort columns. The hist_entry__has_hiearchy_children() is to check whether an entry has lower entries (children) in the hierarchy to be shown in the output. This means the children should not be filtered out and above the percent limit. These two functions will be used to show information when all children of an entry is omitted by the percent limit (or filter). Signed-off-by:

After collecting samples for events 'syscalls:', perf-script with python script doesn't occasionally work generating a segmentation fault. The reason is that the print fmt is empty and a value of event->print_fmt.args is NULL, so dereferencing the null pointer results in a segmentation fault i.e.: # perf record -e syscalls:* # perf script -g python # perf script -s perf-script.py in trace_begin syscalls__sys_enter_brk 3 79841.832099154 3777 test.sh syscall_nr=12, brk=0 ...

The hists__filter_hierarchy() function implements filtering in hierarchy mode. Now we have hist_entry__filter() so use it for entries in the hierarchy. It returns 3 kind of values. A negative value means that it's not filtered by this type. It marks current entry as filtered tentatively so if a lower level entry removes the filter it also removes the all parent so that we can find the entry in the output. Zero means it's filtered out by this type. A positive value means it's not filtered so it removes the filter and shows in the output. In these cases, it moves to next entry since lower level entry won't match by this type of filter anymore. Thus all children will be filtered or not together. Signed-off-by:

The hist_entry__filter() function is to filter hist entries using sort key related info. This is needed to support hierarchy mode since each hist entry will be associated with a hpp fmt which has a sort key. So each entry should compare to only matching type of filters. To do that, add the ->se_filter callback field to struct sort_entry. This callback takes 'type' argument which determines whether it's matching sort key or not. It returns -1 for non-matching type, 0 for filtered entry and 1 for not filtered entries. Signed-off-by:

The rb_hierarchy_{next,prev,last} functions are to traverse all hist entries in a hierarchy. They will be used by various function which supports hierarchy output. As the rb_hierarchy_next() is used to traverse the whole hierarchy, it sometime needs to visit entries regardless of current folding state. So add enum hierarchy_move_dir and pass it to __rb_hierarchy_next() for those cases. Signed-off-by: -

For hierarchical output, each entry must be sorted in their rbtree (hroot) properly. Add hists__hierarchy_output_resort() to do the job. Note that those hierarchy entries share the period counts, it'd be important to update the hists->stats only once (for leaves). Signed-off-by:

In the hierarchical view, entries will be grouped and sorted on the first key, and then on the second key, and so on. Add the he->hroot_{in,out} fields to keep the lower level entries. Actually this can share space, in a union, with callchain's 'sorted_root' since the hroots are only used by non-leaf entries and callchain is only used by leaf entries. It also adds the 'parent_he' and 'depth' fields which can be used by browsers. This patch only implements collapsing part which creates internal entries for each sort key. These need to be sorted by output_sort stage and to be displayed properly in the later patch(es). Signed-off-by: -
