Subject: [PATCH v4 0/2] trace-cmd: Use vsock tracing to find cids and threads
Date: Fri, 14 May 2021 14:29:26 -0400	[thread overview]
Message-ID: <20210514182928.1378121-1-rostedt@goodmis.org> (raw)

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

Use tracing the wake-up and kvm-exit events to find the task that is
owned by the given CID. Also, do the same to find the mappings of
threads and the guest vCPUs.

Changes since v3:

 -  Remove unnecessary check of *cid < 0.

Steven Rostedt (VMware) (2):
  trace-cmd: Find PID of host-guest task from tracing vsock connection
  trace-cmd: Trace timesync to find pids that map vCPUs
