From mboxrd@z Thu Jan 1 00:00:00 1970 From: martink@posteo.de (Martin Kepplinger) Date: Wed, 16 Apr 2014 10:43:49 +0200 Subject: loglevel 7 (debug) and pr_debug() Message-ID: <534E42C5.1040904@posteo.de> To: kernelnewbies@lists.kernelnewbies.org List-Id: kernelnewbies.lists.kernelnewbies.org I'm on Debian here and I don't really get pr_debug and printk(KERN_DEBUG ...). Let's stick to pr_debug. I have DYNAMIC_DEBUG enabled and root at laptop:/proc/sys/kernel# cat /proc/sys/kernel/printk 7 7 1 7 I write a module with pr_debug's. I load the module and I *don't* see anything in /var/log/messages (or anywhere in /var/log/* ). Adding #define DEBUG doesn't help. /sys/kernel/debug/dynamic_debug/control has the pr_debug entries I use in my loaded module. In short: How do I see debug log messages? Using pr_info() works as expected. What am I missing? Do I need to edit my Makefile? thanks! martin -- Martin Kepplinger e-mail martink AT posteo DOT at chat (XMPP) martink AT jabber DOT at
