[Sound-open-firmware] [PATCH] Use tracev instead of trace for dai irq event.
From: Yan Wang yan.wang@linux.intel.com
This event is in pipeline and will produce many trace data in a short time. It should use tracev to disable it by default.

Applied. The intention for trace is the pipeline/component copy() and IRQ trace messages should be verbose due their high frequency.
In 1.2 I'd like to see a debugFS file that can enable/disable trace and verbose trace per subsystem/component at runtime.
e.g.
echo off > /sys/kernel/debug/sof/trace_level echo on > /sys/kernel/debug/sof/trace_level echo src > /sys/kernel/debug/sof/trace_level echo pipeline > /sys/kernel/debug/sof/trace_level echo scheduler > /sys/kernel/debug/sof/trace_level
