Enhancement: Support out-of-tree tracing backends #37912

Open mullr opened 3 years ago

mullr commented 3 years ago

Is your enhancement proposal related to a problem? Please describe. I'm hooking up a custom tracing system to Zephyr. The macro-based tracing hooks are almost a really good place to hook in to this. Unfortunately, the source structure only accommodates in-tree definitions of the sys_port_trace_* macros.

Describe the solution you'd like I'd like a way to provide my own include file, like tracing_sysview.h, from outside the zephyr source tree.

Describe alternatives you've considered I've been able to work around this by providing my own tracing/tracing.h file, and putting it on the front of the include path. This mostly works, but there appear to be some source files (subsys/net/buf.c is one) that don't actually include tracing/tracing.h; to work around these cases, I had to add -include 'tracing/tracing.h' to my CFLAGS as well.

I also looked at the existing tracing backend hook in tracing_backend.h, but it's too high-level for my application.
