Debug / Developer Features
The
tenstorrent,vuart
virtual PCIe serial device is now the default for console I/O. The virtual uart supports multiple instances, so one instance may be used for console I/O while another instance may be used for e.g. RPC, tracing, coredump, profiling, or other functionality
Zephyr’s tracing subsystem may now be used over the virtual uart. For now it is limited to a an app overlay but plans are in place to integrate this feature into production firmware with support for dynamically configurable tracing
