Note: This article is currently only a draft and is a part of a series of articles I'm going to publish the next few months - if you want to contribute to it, please feel free to. However it would be nice if you could coordinate your efforts with me

What this article will be about - ideas

  • printk format
  • Debug/log levels - dmesg -n /proc/sys/kernel/printk
  • printk_ratelimited
  • dynamic debug, pr_debug and dev_dbg
  • pr_warn and family - see printk.h for details
  • early_printk
  • printascii, printch and printhex (on ARM only?)
  • /dev/kmsg
  • Examples - maybe use example module.
