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:

take care,
Gerd
