When doing pmu sampling and then running a script with perf script -s
script.py, the process_event function gets dictionary with some fields
from the perf ring buffer (like ip, sym, callchain etc).
But we miss quite a few fields we report now, for example, LBRs, data
source, weight, transaction, iregs, uregs, etc.
This patch reports these fields for perf script python processing.
New keys/items:
---------------
key : brstack
items: from, to, from_dsoname, to_dsoname, mispred,
predicted, in_tx, abort, cycles.
key : brstacksym
items: from, to, pred, in_tx, abort (converted string)
key : datasrc
key : datasrc_decode (decoded string)
key : iregs
key : uregs
key : weight
key : transaction
v2:
---
Add new fields for dso.
Use PyBool_FromLong() for mispred/predicted/in_tx/abort
Committer notes:
!sym->name isn't valid, as its not a pointer, its a [0] array, use
!sym->name[0] instead, guaranteed to be the case by symbol__new.
This was caught by just one of the containers:
