Hello Kernel - karthikbalaguru - 14:40 03-06-08



Hi,

I would like to pass commands from Shell
and check the information exchanged
between different routines in Kernel Space ?
Other than printk , Is there any tool / method
to do that ?

Thx in advans,

Let's step back for a moment. What is it that you're trying to do? I don't 
mean "check the information in the kernel being passed from shell 
commands" - I mean at a higher level. What problem/issue are you trying to 
solve where you think you need to do this?

Look at procfs (the virtual files in /proc) some of which are now
supposed to
be in sysfs (/sys) under  2.6 kernels.

A number of kernel modules will create status files in one of these
places that you can view to see what they are up to.  You'd have to
examine them to see how they do it.  The spi mmc card driver does this
for example.
