[PATCH v2] media: staging: tegra-vde: Replace debug messages with trace points

From: Dmitry Osipenko
Date: Tue Jul 17 2018 - 07:08:14 EST

Next message: Sangwon Hong: "[PATCH] perf list: Document missing options"
Previous message: Claudiu Beznea: "[RESEND PATCH] ARM: at91: pm: configure wakeup sources for ULP1 mode"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Trace points are much more efficient than debug messages for extensive
tracing and could be conveniently enabled / disabled dynamically, hence
let's replace debug messages with the trace points.

Signed-off-by: Dmitry Osipenko <digetx@xxxxxxxxx>

Changelog:

v2:
- Use __assign_str() for copying of HW sub-engine name during of
tracing. There is no functional changes since V1, that's just a
bit better variant of the patch that doesn't rely on stopping
tracing before releasing of managed resources (struct tegra_vde).
