Thomas Kolb f6404dd0ea Move payload CRC to layer 2 
Layer 1 only does decoding of the FEC, but the CRC check for data integrity is
done in layer 2 now.

Thomas Kolb 0e8e049e0a Replace all perror() calls with LOG() 2024-05-30 11:02:08 +02:00
Thomas Kolb 65daa182ef Use the new logging system everywhere 2024-05-30 10:49:43 +02:00
Thomas Kolb d6eaef91cd Switch to new logging system 
The new system supports:

- time-tagging of log messages
- message priority levels with a threshold below which they are not printed
- colored output of the message priority for easy identification
- compile-time disabling of all logging per C module

So far, it is integrated in the main and rx modules which generate most
messages. Other modules will be migrated in the future.

Simon Ruderich bc2f5ca76c visualizer: assign id to identify packets 
The id is displayed in the graph, the packet information and in the
trace (on mouse over).

Simon Ruderich c63f7e8b57 visualizer: treat -1e38 as NaN 
I considered updating jsonlogger.c to represent NaN as "null" in the
JSON. However, this makes the hand-written JSON generator much more
complicated.

Simon Ruderich 53190cd17c visualizer: don't use fixed scales

Simon Ruderich 5fb5a2908d jsonlogger: increase pipe buffer to reduce likelihood of corrupted messages 
Our JSON messages can get rather large which can cause a buffer overrun
when the reading program is not scheduled at the same time. When the
kernel returns EAGAIN we abort writing the current JSON message.
However, the unfinished (and thus invalid) JSON message is still in the
pipe and will be processed by the reading program.

Increase the pipe buffer from the default 65536 to reduce the likelihood
of this happening. It's difficult to completely prevent the issue as we
don't want to slow down the main program due to slow logging.

Thomas Kolb 5f8346d290 agc: update squelch threshold more often 
This fixes the noise level tracking in test cases like the loopback
test where the signal has already ramped up before the first noise level
update.
