From: Jin Yao <yao....@linux.intel.com> It's a follow up for one previous patch "perf tool: Improve bash command line auto-complete for multiple events with comma."
It fixes an issue that no events are displayed when <TAB> is directly typed after comma. With this patch, now the result is: root@skl:/tmp# perf stat -e cpu-cycles,<TAB> Display all 2389 possibilities? (y or n) alarmtimer:alarmtimer_cancel alarmtimer:alarmtimer_fired alarmtimer:alarmtimer_start alarmtimer:alarmtimer_suspend alignment-faults arith.divider_active BAClear_Cost baclears.any block:block_bio_backmerge block:block_bio_bounce block:block_bio_complete block:block_bio_frontmerge block:block_bio_queue block:block_bio_remap block:block_dirty_buffer block:block_getrq block:block_plug block:block_rq_complete block:block_rq_insert block:block_rq_issue block:block_rq_remap block:block_rq_requeue block:block_sleeprq --More-- One remaining issue is that the auto-completions doesn't work well for the event with ':'. For example, clk:clk_enable. Because ':' is set as WORDBREAK by default in bash. Need more work for this case.
