From 85efe4e5082c381262f5303d20f808ac455b028e Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Fri, 10 Jul 2015 10:49:24 -0300 Subject: [media] v4l2-dev: use event class to deduplicate v4l2 trace events Trace events with exactly the same parameters and trace output, such as v4l2_qbuf and v4l2_dqbuf, are supposed to use the DECLARE_EVENT_CLASS and DEFINE_EVENT macros instead of duplicated TRACE_EVENT macro calls.

This allows to make sense of the timeline of trace events in combination with others that might be triggered by __enqueue_in_driver. Also two new trace events vb2_buf_queue and vb2_buf_done are added, allowing to trace the handover between videobuf2 framework and driver.
