Subject: [PATCH v4 00/13] [RfC] fix tracing for modules
Date: Tue,  1 Jun 2021 15:24:01 +0200	[thread overview]
Message-ID: <20210601132414.432430-1-kraxel@redhat.com> (raw)

First version that actually works.  Only qxl covered for this RfC,
other modules will follow once the basics are hashed out.

v4:
 - rebase to latest master.
 - fix systemtap tracing.
 - also cover virtio-gpu modules.
 - pick up some review tags.
 - misc minor tweaks.

v3:
 - handle initialization of modular tracepoints.

TODO:
Enabling modular tracepoints via -trace cmd line doesn't work yet.
Guess we need to store the list somewhere for later re-processing.
Error handling is tricky, specifically the "tracepoint doesn't exist"
error.  Suggestions / ideas are welcome.

More context:
  https://bugzilla.redhat.com/show_bug.cgi?id=1898700
  https://bugzilla.redhat.com/show_bug.cgi?id=1869642

take care,
  Gerd
