Define 2 new flags to represent:
- when interrupts are disabled (D)
- when interrupt disabling toggles (t)
This gives 4 combinations:
no flag, interrupts enabled
t interrupts were enabled but become disabled
D interrupts are disabled
Dt interrupts were disabled but become enabled
Committer notes:
Those are control flow flags, as per 'tools/perf/Documentation/perf-intel-pt.txt:
<quote>
An interesting field that is not printed by default is 'flags' which can be
displayed as follows:
perf script --itrace=ibxwpe -F+flags
The flags are "bcrosyiABExgh" which stand for branch, call, return, conditional,
system, asynchronous, interrupt, transaction abort, trace begin, trace end,
in transaction, VM-entry, and VM-exit respectively.
