Subject: media: visl: Add a tpg_verbose parameter
Author: Detlev Casanova <detlev.casan...@collabora.com>
Date: Wed Jan 17 10:10:16 2024 -0500
The text written on the output frames stable for a given input.
Remove the unstable elements like pointers, buffer indexes or queues
status so that frames are always identical and can be compared against
a reference in automatic tests.
As the unstable information can be relevant when debugging the API, add
a tpg_verbose parameter to show them.
