[Minios-devel] [UNIKRAFT PATCH 0/8] introduce trace points

[Yuri Volchkov <yuri.volchkov@xxxxxxxxx>]

This series brings functionality of statically declared trace points.
Declaration is fully static. Information is stored in 2 elf sections,
which are stripped at the final stage of building. This sections are
used only offline by trace.py script, to parse the trace buffer.

Once a trace point is declared, it can be called from runtime. The
tracepoint automatically saves the timestamp, and all passed data into
a tracebuffer.

Depends on:
"include/essentials.h: introduce compile-time assert"
"build: reorganize linking"


Yuri Volchkov (8):
  lib/ukdebug: trace.h - introduce UK_FOREACH and UK_NARGS macros
  lib/ukdebug: Register a tracepoint
  lib/ukdebug: save actual data into a tracebuffer
  lib/ukdebug: key-value static storage for tracing
  support/scripts: fetch trace data from running unikraft
  support/scripts: implement trace buffer parcing
  lib/vfscore: replace tracing stabs with new tracepoints
  doc/guides: Add section about tracepoints
