NAME

       tracy-import-fuchsia - Import Fuchsia's traces into Tracy

SYNOPSIS

       tracy-import-fuchsia input.fxt output.tracy

DESCRIPTION

       Tracy can import traces compressed with the Zstandard algorithm (for example, using the zstd command-line
       utility).  Traces ending with .zst extension are assumed to be compressed.

       Chrome  tracing format doesn't document a way to provide source location data.  The import-chrome and im‐
       port-fuchsia utilities will however recognize a custom loc tag in the root of  zone  begin  events.   You
       should  be formatting this data in the usual filename:line style, for example: hello.c:42.  Providing the
       line number (including a colon) is optional but highly recommended.

       See <https://fuchsia.dev/fuchsia-src/reference/tracing/trace-format> for more information  about  fuchsia
       trace format.

LIMITATIONS

       • Tracy  is  a single-process profiler.  Should the imported trace contain PID entries, each PID+TID pair
         will create a new pseudo-TID number, which the profiler will then decode into a PID+TID pair in  thread
         labels.  If you want to preserve the original TID numbers, your traces should omit PID entries.

       • The  imported  data may be severely limited, either by not mapping directly to the data structures used
         by Tracy or by following undocumented practices.
