Netconsole is subject to console filtering (which we _do_ want as
debug messages going out the uart slows the whole world down).

netconsole and netoops _do_ have bits in common, for instance the
handling of NETDEV events and source+target configuration. I'd rather
those bits become common between the two than figure out how to jam
the semantics we need into netconsole.

Hi Matt,

I've been reading through the netconsole driver in response to Greg's comments on this thread, and it is definitely more robust in terms of configuration and handling of network device events than the netoops driver I proposed.

What are your thoughts on extending netconsole with the same sort of semantics that are in the netoops patchset?

I'd still like to have blit-dmesg-to-the-network-on-oops semantics, which seems doable by having a per-target flag for streaming of console messages (enabled by default) and a flag to emit a structured full dmesg dump (disabled by default).

I'd be happy to change this patchset to modify the netconsole driver if you agree.

Thanks,

Mike Waychison
