|i synthesize instructions events
|b synthesize branches events (branch misses for Arm SPE)
|c synthesize branches events (calls only)
|r synthesize branches events (returns only)
|x synthesize transactions events
|w synthesize ptwrite events
|p synthesize power events
|o synthesize other events recorded due to the use
|of aux-output (refer to perf record)
|e synthesize error events
|d create a debug log
|f synthesize first level cache events
|m synthesize last level cache events
|t synthesize TLB events
|a synthesize remote access events
|g synthesize a call chain (use with i or x)
|G synthesize a call chain on existing event records
|l synthesize last branch entries (use with i or x)
|L synthesize last branch entries on existing event records
|s skip initial number of events
|q quicker (less detailed) decoding
|The default is all events i.e. the same as --itrace=ibxwpe,
|except for perf script where it is --itrace=ce
|In addition, the period (default 100000, except for perf script where it is 1)
|for instructions events can be specified in units of:
|ns nanoseconds (default)
|Also the call chain size (default 16, max. 1024) for instructions or
|transactions events can be specified.
|Also the number of last branch entries (default 64, max. 1024) for
|instructions or transactions events can be specified.
|Similar to options g and l, size may also be specified for options G and L.
|On x86, note that G and L work poorly when data has been recorded with
|large PEBS. Refer linkperf:perf-intel-pt man page for details.
|It is also possible to skip events generated (instructions, branches, transactions,
|ptwrite, power) at the beginning. This is useful to ignore initialization code.
|skips the first million instructions.
|The 'e' option may be followed by flags which affect what errors will or
|will not be reported. Each flag must be preceded by either '+' or '-'.
|The flags are:
|l trace data lost
|If supported, the 'd' option may be followed by flags which affect what
|debug messages will or will not be logged. Each flag must be preceded
|by either '+' or '-'. The flags are:
|a all perf events
|If supported, the 'q' option may be repeated to increase the effect.
