Subject: [PATCH 0/9] perf tools: Report event parsing errors
hi,
adding support to report error from event string parsing.
v1 changes (from RFC):
- display list of allowed terms for pmu event error [Ingo]
- changing 'invalid or unsupported event' string into
'event syntax error' for cases we know the precise error
This patchset contains support for standard parsing errors
and more logic to recognize tracepoint and 'pmu//' terms,
like:
$ sudo perf record -e 'sched:krava' ls
event syntax error: 'sched:krava'
\___ unknown tracepoint
...
$ perf record -e 'cpu/even=0x1/' ls
event syntax error: 'cpu/even=0x1/'
\___ unknown term
valid terms: pc,any,inv,edge,cmask,event,in_tx,ldlat,umask,in_tx_cp,offcore_rsp,config,config1,config2..
...
$ perf record -e cycles,cache-mises ls
event syntax error: '..es,cache-mises'
\___ parser error
...
Changes are also reachable in here:

thanks
