The nr_sort_keys field is to carry the number of sort entries in a hpp_list or hists to determine the depth of indentation of a hist entry. As it's only used in hierarchy mode and now we have used nr_hpp_node for this reason, there's no need to keep it anymore. Let's get rid of it.

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: NNamhyung Kim <namhyung@kernel.org> Tested-by: NArnaldo Carvalho de Melo <acme@redhat.com> Acked-by: NJiri Olsa <jolsa@kernel.org> Cc: Andi Kleen <andi@firstfloor.org> Cc: David Ahern <dsahern@gmail.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1456512767-1164-2-git-send-email-namhyung@kernel.orgSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

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).

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.

We were doing column alignment in the format function for each cell, returning a string padded with spaces so that when the next column is printed the cursor is at its column alignment. This ends up needlessly printing trailing spaces, do it at the format iterator, that is where we know if it is needed, i.e. if there is more columns to be printed. This eliminates the need for triming lines when doing a dump using 'P' in the TUI browser and also produces far saner results with things like piping 'perf report' to 'less'. Right now only the formatters for sym->name and the 'locked' column (perf mem report), that are the ones that end up at the end of lines in the default 'perf report', 'perf top' and 'perf mem report' tools, the others will be done in a subsequent patch. In the end the 'width' parameter for the formatters now mean, in 'printf' terms, the 'precision', where before it was the field 'width'.

When there are multiple events, each dynamic sort key is defined just for one event. In this case other events will always show "N/A" for those fields. But they are meaningless and consume precious screen width. Let's skip those undefined dynamic fields. $ perf record -e kmem:kmalloc,kmem:kfree -a sleep 1 $ perf report -s 'comm,kmalloc.*' --stdio # To display the perf.data header info, please use --header/--header-only options. # # # Total Lost Samples: 0 # # Samples: 20K of event 'kmem:kmalloc' # Event count (approx.): 20533 # # Overhead Command call_site ptr bytes_req bytes_alloc gfp_flags # ........ ....... .................. .................. ......... ........... ................... # 99.89% perf ffffffffa01d4396 0xffff8803ffb79720 96 96 GFP_NOFS|GFP_ZERO 0.06% sleep ffffffff8114e1cd 0xffff8803d228a000 4096 4096 GFP_KERNEL 0.03% perf ffffffff811d6ae6 0xffff8803f7678f00 240 256 GFP_KERNEL|GFP_ZERO 0.00% perf ffffffff812263c1 0xffff880406172380 128 128 GFP_KERNEL 0.00% perf ffffffff812264b9 0xffff8803ffac1600 504 512 GFP_KERNEL 0.00% perf ffffffff81226634 0xffff880401dc5280 28 32 GFP_KERNEL 0.00% sleep ffffffff81226da9 0xffff8803ffac3a00 392 512 GFP_KERNEL # Samples: 20K of event 'kmem:kfree' # Event count (approx.): 20597 # # Overhead Command # ........ .............. # 99.63% perf 0.14% sleep 0.11% irq/36-iwlwifi 0.11% kworker/u16:0 0.01% Xorg 0.00% firefox Signed-off-by: NNamhyung Kim <namhyung@kernel.org> Acked-by: NJiri Olsa <jolsa@kernel.org> Tested-by: NArnaldo Carvalho de Melo <acme@redhat.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1450804030-29193-12-git-send-email-namhyung@kernel.orgSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

The 'trace' sort key is to show tracepoint event output using either print fmt or plugin. For example sched_switch event (using plugin) will show output like below: # perf record -e sched:sched_switch -a usleep 10 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.197 MB perf.data (69 samples) ] # $ perf report -s trace --stdio ... # Overhead Trace output # ........ ................................................... # 9.48% swapper/0:0 [120] R ==> transmission-gt:17773 [120] 9.48% transmission-gt:17773 [120] S ==> swapper/0:0 [120] 9.04% swapper/2:0 [120] R ==> transmission-gt:17773 [120] 8.92% transmission-gt:17773 [120] S ==> swapper/2:0 [120] 5.25% swapper/0:0 [120] R ==> kworker/0:1H:109 [100] 5.21% kworker/0:1H:109 [100] S ==> swapper/0:0 [120] 1.78% swapper/3:0 [120] R ==> transmission-gt:17773 [120] 1.78% transmission-gt:17773 [120] S ==> swapper/3:0 [120] 1.53% Xephyr:6524 [120] S ==> swapper/0:0 [120] 1.53% swapper/0:0 [120] R ==> Xephyr:6524 [120] 1.17% swapper/2:0 [120] R ==> irq/33-iwlwifi:233 [49] 1.13% irq/33-iwlwifi:233 [49] S ==> swapper/2:0 [120] Note that the 'trace' sort key works only for tracepoint events. If it's used to other type of events, just "N/A" will be printed.

This is a preparation to add more info into the hist_entry. Also it already passes too many argument, so passing sample directly will reduce the overhead of the function call.

Sorting on 'symbol' gives to broad a resolution as it can cover a range of IP address. Use the iaddr instead to get proper sorting on IP addresses. Need to use the 'mem_sort' feature of perf record.
