editing and building ./drivers/pci/iov.c

[Kelly Zytaruk]

I am trying to trace a bug I have with some hardware and I am putting
printk() statements in iov.c

 

Every time I make a change to the source file, I am building the entire
linux kernel, ie 'make' from top directory.

While it is not complex, it is time consuming, it takes several minutes to
go through all of the dependencies and link all of the modules together.

I spend a lot of time waiting.

 

Am I doing this correctly or is there a short cut to do either of the
following;

1)      Compile only iov.c to find coding syntax errors

a.       I tried running 'make' in the ./drivers/pci directory but it told
me that there were no targets.

2)      Do the final build.

a.       Do I have to build the entire linux kernel or can I somehow
insert/replace the pci driver into an existing image.

 

Thanks,

Kelly
