2016-07-15perf tools: Bail out at "--sort dcacheline" and cacheline_size not knownArnaldo Carvalho de Melo1-1/+7
There are cases where further work would be needed to overcome the fact that neither sysconf(_SC_LEVEL1_DCACHE_LINESIZE) nor /sys/devices/system/cpu/cpu0/cache/index0/coherency_line_size are available in some systems (Android, for instance), so bail out when such a situation takes place.

This implements having multiple sort keys in a single hierarchy level. Originally only single sort key is supported for each level, but now using the group syntax with '{ }', it can set more than one sort key in one level. Note that now it needs to quote in order to prevent shell interpretation. For example: $ perf report --hierarchy -s '{comm,dso},sym' ... # Overhead Command / Shared Object / Symbol # .............. .......................................... # 48.67% swapper [kernel.vmlinux] 34.42% [k] intel_idle 1.30% [k] __tick_nohz_idle_enter 1.03% [k] cpuidle_reflect 8.87% firefox libpthread-2.22.so 6.60% [.] __GI___libc_recvmsg 1.18% [.] pthread_cond_signal@@GLIBC_2.3.2 1.09% [.] 0x000000000000ff4b 6.11% Xorg libc-2.22.so 5.27% [.] __memcpy_sse2_unaligned In the above example, the command name and the shared object name are shown on the same line but the symbol name is on the different line. Since the first two are grouped by '{}', they are in the same level.

2016-02-26perf report: Update column width of dynamic entriesNamhyung Kim1-3/+5
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.

2016-02-26perf hists: Fix dynamic entry display in hierarchyNamhyung Kim1-0/+3
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.

2016-02-26perf report: Fix indentation of dynamic entries in hierarchyNamhyung Kim1-0/+19
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.

2016-02-24perf hists: Introduce hist_entry__filter()Namhyung Kim1-0/+113
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.

This is because the entry is so unique and other sort keys already make it distinct. Then the srcline/file sort didn't have a chance to be called during the sorting. In that case it has NULL srcline/srcfile field and shows nothing. Before: $ perf report -s comm,sym,srcline ...

2016-02-12perf hists: Do column alignment on the format iteratorArnaldo Carvalho de Melo1-10/+3
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'.
