In effect one could define a tree, akin to sysctl that provided all these layers. ... Effectively a description file like this:
all all.kern all.kern.dev all.kern.dev.fxp all.kern.dev.fxp.rx all.kern.dev.fxp.tx .. ... Then inside the program one would simply write:
alfred_printf(all_kern_dev_fxp, 1, "Fxp initialized");
then maybe in the rx routine:
alfred_printf(all_kern_dev_fxp_rx, 2, "Fxp got packet");
For some reason this struck a note. While this was done for debug levels and may not directly apply to generic console output and redirection, it did put a seed in my head relating to device_printf(). Nothing concrete and it may not be anything, but still :-)
so you like it? I do!
