## Tracing
A more advanced version of logging can be accomplished via qemu's tracing infrastructure. Documentation for such is located underneath `docs/devel/tracing.rst`. Review the `trace-events` files within the source tree to see what's supported.

#### Runtime Usage (preferred)
TODO:
Launch xemu from a console window (cmd.exe, Terminal.app, bash, etc...; whichever is appropriate for your OS).
Open the monitor via <kbd>Debug</kbd> &rarr; <kbd>Monitor</kbd> in the xemu menu.
Enter `trace-event <trace_event> on` to turn on an event, `trace-event <trace_event> off` to turn one off, replacing `<trace_event>` with the name of the event you wish to toggle.
Examine the console where you launched xemu; trace messages will be written to `STDERR`.
The [nv2a events](https://github.com/mborgerson/xemu/blob/master/hw/xbox/nv2a/trace-events){target=_blank} are particularly interesting when debugging graphics issues, specifically the `nv2a_pgraph_*` subset. These may be toggled all at once using a wildcard. For example, `trace-event nv2a_pgraph_* on` will turn them all on.
#### Compile-Time Usage (deprecated)
Append `--enable-trace-backends=simple` to the xemu build args to enable.
Append `--debug --enable-trace-backends=simple` to the xemu build args to enable.
Edit the global `/tmp/events` file with things you intend to match on.

$ cat /tmp/events
Then append `--trace events=/tmp/events` to the xemu runtime arguments. Once finished, run `python ./scripts/simpletrace.py trace-events-all trace-####` replacing `####` with the created trace log's ID.
