virtio Device testing

[Abhishek Srivastava <asrivas.dfly@xxxxxxxxx>]

Hi All,

I have been working on developing virtio device drivers for dragonfly,
especially for the block and the network devices.

When i build the module into a .ko, the target directory gets filled
with a number of links like this : 

drwxr-xr-x  3 abhi abhi  4096 2010-05-21 22:06 .
drwxr-xr-x 21 abhi abhi  4096 2010-05-21 21:59 ..
lrwxrwxrwx  1 abhi abhi    43 2010-05-21 22:06 @
-> /usr/src/src/dragonfly/sys/dev/virtio/../..
-rw-r--r--  1 abhi abhi 10756 2010-05-21 22:06 bus_if.h
lrwxrwxrwx  1 abhi abhi    60 2010-05-21 22:06 cpu
-> /usr/src/src/dragonfly/sys/dev/virtio/../../cpu/i386/include
lrwxrwxrwx  1 abhi abhi    52 2010-05-21 22:06 cpu_base

-rw-r--r--  1 abhi abhi  2075 2010-05-21 22:06 device_if.h
drwxr-xr-x  3 abhi abhi  4096 2010-05-21 22:06 forwarder_i386

lrwxrwxrwx  1 abhi abhi    57 2010-05-21 22:06 machine_base
-> /usr/src/src/dragonfly/sys/dev/virtio/../../platform/pc32
-rw-r--r--  1 abhi abhi    82 2010-05-21 21:59 Makefile
-rw-r--r--  1 abhi abhi  6692 2010-05-21 22:06 pci_if.h

abhi@debian:/mnt/dfly/src/dragonfly/sys/dev/virtio$ 

 
And if i try to rebuild the module after some changes, it complains
about not finding forwarder_i386 (broken link). Then I have to re-clean
the directory, put the module code there and start over. Is it always
the case that these links are made to the sys directories for compiling
modules ? My module code is in the sys/dev directory in any case.


Thanks,
Abhishek.
