Hello,
I have got some questions about driver development on Linux 2.6:
Is there somebody who can explain, what is meant with wait_event and
wake_up? Does it mean,
when I run "ifconfig", and the driver says "wait_event", is "ifconfig"
blocked until my driver which
is continuing his work says "wake_up"? Have I explained this correctly?
If I give wait_event a condition, is it right that the driver continues
its work and ifconfig is
blocked until the driver does something that sets this condition true?
Something else: we need a driver, which establishes an IP layer on top
of the VME bus
to transfer data via a network device (called dpn). On the other side
this driver must be
able to communicate with passive modules inside the vme-rack by polling
their shared
memory for data.
Is it possible to create two kernel modules which run with the same
hardware? One
module for the communication with the active VME modules via IP and
another one
for the communication with the passive VME modules by polling their
shared memory?
Many questions, I know. But I am an absolute newbie in driver
development. And I
hope you can help me.
If somebody knows a source of informations regarding this topic, which
is held in
german, please tell me.
Thanks a lot
kind regards
Hendrik (Germany)
