Add a trace event buffer that can be used by userspace to read DSP runtime trace events alongside bespoke trace data in realtime for firmware debug.
Should this be integrated into the Linux trace event mechanism rather than open coded? It would at least be nice to not call this a trace event buffer - when I initially read this I was expecting it to be for the standard Linux stuff which obviously it isn't.
Your right, I'll rename. The eventual aim is to make it more like Linux trace but we are constrained somewhat as some DSPs only 96kB or instruction RAM, hence it's a simple and raw trace infrastructure.
