[PATCH v4 2/4] media: visl: Add a tpg_verbose parameter
From: Detlev Casanova
Date: Fri Dec 15 2023 - 11:45:23 EST
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.
