kernel.git/drivers/hwtracing/stm/console.c, branch masterHosts the 0x221E linux distro kernel.
https://git.0xinfinity.dev/distro/kernel.git/atom?h=master2024-05-04T16:57:21Zstm class: Add source type2024-05-04T16:57:21ZMikhail Lappo2024-04-29T13:01:06Zurn:sha1:07cf835689d700d46d88b5bbffc32bc210319f5f
Currently kernel HW tracing infrastrtucture and specifically its SyS-T
part treats all source data in the same way. Treating and encoding
different trace data sources differently might allow decoding software
to make use of e.g. ftrace event ids by converting them to a SyS-T
message catalog.
The solution is to keep source type stored within stm_source_data
structure to allow different handling by stm output/protocol.
Currently we only differentiate between STM_USER and STM_FTRACE sources.

stm class: stm_console: Add kernel-console-over-stm driver2015-10-04T19:28:58ZAlexander Shishkin2015-09-22T12:47:13Zurn:sha1:e3e5a3d3da3e68ac5a7ab0278dffec8353ca8174
This is a simple stm_source class device driver (kernelspace stm trace
source) that registers a console and sends kernel messages over STM
devices.
