I'm using a device that spams kernel messages excessively (10-100 messages a second, Mediatek drivers...), where it is infeasible to remove the logging from the kernel itself (spread across hundreds of files).
I've accepted that dmesg is all but useless on this device, but unfortunately the systemd journal is also affected.
Is it possible to filter/disable logging kernel messages into the systemd journal?
Instead of disabling the logging of kernel messages, I would investigate the reason why mediatek drivers produce such a high level of output and what can be done about it. Kernel messages are quite useful. – MariusMatutiae – 2018-06-23T16:57:22.037
I completely agree, but the output from these Mediatek drivers is just ridiculous. It spams several lines (of all available priorities) for things like turning on/off a CPU core or the battery voltage changing by a minuscule amount.
There is no way to stop the spam that I can see, each driver uses its own hard-coded logging configuration, best I can do is comment out the worst culprits – Luke F – 2018-06-23T20:40:04.953
