It normally prints to the syslogd facility, which by default makes it come out in the file /var/log/messages and also for important enough messages comes out on the console. Note that if you write your own console driver, you probably need to write _two_ drivers: the actual console driver used by printk (the read routine seems to be unused), and a serial I/O driver which will be opened by the kernel for the init process. Console drivers themselves do not appear in the filesystem, but are registered via register_console(). The serial I/O device needs to appear in the filesystem for the kernel to open it for init, so should be a standard char device. > In which file I can find it ? kernel/printk.c Tom Roberts tjroberts at lucent.com ** Sent via the linuxppc-embedded mail list.
