ltrace - LAMEbus trace device
device ltrace* at lamebus*
ltrace is a driver for the LAMEbus trace and debug card. This device can be used to turn on and off System/161 tracing (with trace161); it can also be used to emit debug printouts with much lower latency than printing to the console. Finally, it can be used to cause a dump of the entire System/161 system state.
The calls for these operations are provided to the kernel via the header file <lamebus/ltrace.h>.
Only the first ltrace device found, if any, is actually used. If none is found, the calls have no effect.
