From 1d0dc1ddf037b2f5ef205a4343cfe1384b769d7c Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Mon, 24 Jan 2022 10:41:47 +0200 Subject: [PATCH] perf tools: Define new D (Intr Disable) and t (Intr Toggle) flags 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: 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.
