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 import-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.
