Subject: [PATCH 0/5] loglevel=pci:7,acpi:6 support v3
Date: Tue, 16 Sep 2008 16:13:53 -0700 [thread overview]
Message-ID: <1221606838-30246-1-git-send-email-yhlu.kernel@gmail.com> (raw)
usage:
in .h to have
#define KERN_PCI "<pci>"
in .c to have
DEFINE_LOGLEVEL_SETUP(pci, KERN_PCI, "pci:");
then could use
printk(KERN_DEBUG KERN_PCI fmt, ...);
and command line
loglevel=pci:8
you can add different printk to different files of one subsys if you like
not just one susbsys one tag, and don't need to update kernel.h to add more tags
