Subject: [PATCH 15/35] perf script: Add machine_pid and vcpu
Date: Mon, 11 Jul 2022 12:31:58 +0300 [thread overview]
Message-ID: <20220711093218.10967-16-adrian.hunter@intel.com> (raw)
In-Reply-To: <20220711093218.10967-1-adrian.hunter@intel.com>
Add fields machine_pid and vcpu. These are displayed only if machine_pid is
non-zero.

The ipc (instructions per cycle) field is synthesized and may have a value when
Instruction Trace decoding.
+ The machine_pid and vcpu fields are derived from data resulting from using
+ perf insert to insert a perf.data file recorded inside a virtual machine into

Finally, a user may not set fields to none for all event types.
i.e., -F "" is not allowed.
