2012-03-16	perf tools: Add config options support for event parsing	Jiri Olsa	1	-1/+1
	Adding a new rule to the event grammar to be able to specify values of additional attributes of symbolic event. The new syntax for event symbolic definition is: event_legacy_symbol: PE_NAME_SYM '/' event_config '/' \| PE_NAME_SYM sep_slash_dc event_config: event_config ',' event_term \| event_term event_term: PE_NAME '=' PE_NAME \| PE_NAME '=' PE_VALUE PE_NAME sep_slash_dc: '/' \| ':' \| At the moment the config options are hardcoded to be used for legacy symbol events to define several perf_event_attr fields. It is: 'config' to define perf_event_attr::config 'config1' to define perf_event_attr::config1 'config2' to define perf_event_attr::config2 'period' to define perf_event_attr::sample_period Legacy events could be now specified as: cycles/period=100000/ If term is specified without the value assignment, then 1 is assigned by default.

2012-03-16	perf tools: Add parser generator for events parsing	Jiri Olsa	1	-0/+316
	Changing event parsing to use flex/bison parse generator. The event syntax stays as it was. grammar description: events: events ',' event \| event event: event_def PE_MODIFIER_EVENT \| event_def event_def: event_legacy_symbol sep_dc \| event_legacy_cache sep_dc \| event_legacy_breakpoint sep_dc \| event_legacy_tracepoint sep_dc \| event_legacy_numeric sep_dc \| event_legacy_raw sep_dc event_legacy_symbol: PE_NAME_SYM event_legacy_cache: PE_NAME_CACHE_TYPE '-' PE_NAME_CACHE_OP_RESULT '-' PE_NAME_CACHE_OP_RESULT \| PE_NAME_CACHE_TYPE '-' PE_NAME_CACHE_OP_RESULT \| PE_NAME_CACHE_TYPE event_legacy_raw: PE_SEP_RAW PE_VALUE event_legacy_numeric: PE_VALUE ':' PE_VALUE event_legacy_breakpoint: PE_SEP_BP ':' PE_VALUE ':' PE_MODIFIER_BP event_breakpoint_type: PE_MODIFIER_BPTYPE \| empty PE_NAME_SYM: cpu-cycles\|cycles \| stalled-cycles-frontend\|idle-cycles-frontend \| stalled-cycles-backend\|idle-cycles-backend \| instructions \| cache-references \| cache-misses \| branch-instructions\|branches \| branch-misses \| bus-cycles \| cpu-clock \| task-clock \| page-faults\|faults \| minor-faults \| major-faults \| context-switches\|cs \| cpu-migrations\|migrations \| alignment-faults \| emulation-faults PE_NAME_CACHE_TYPE: L1-dcache\|l1-d\|l1d\|L1-data \| L1-icache\|l1-i\|l1i\|L1-instruction \| LLC\|L2 \| dTLB\|d-tlb\|Data-TLB \| iTLB\|i-tlb\|Instruction-TLB \| branch\|branches\|bpu\|btb\|bpc \| node PE_NAME_CACHE_OP_RESULT: load\|loads\|read \| store\|stores\|write \| prefetch\|prefetches \| speculative-read\|speculative-load \| refs\|Reference\|ops\|access \| misses\|miss PE_MODIFIER_EVENT: [ukhp]{0,5} PE_MODIFIER_BP: [rwx] PE_SEP_BP: 'mem' PE_SEP_RAW: 'r' sep_dc: ':' \| Added flex/bison files for event grammar parsing. The generated parser is part of the patch. Added makefile rule 'event-parser' to generate the parser code out of the bison/flex sources.
