Hi,
I am working on a project where I need to send packets in real time using a
pcmcia wavelan device. I am trying to use RTlinux for the real time part of
it.
I decided to let the device driver remain in linux - ie I open and set up
the device in linux. I only move the part where the packets are written and
read from the device to RTlinux.
Going over the documentaion for RTL & thru the archives of this list I
realized that for communication (transferring packets & control messages)
between linux & RTL only fifos can be used.
The problem I am faced with is how to open,read & write to the RTfifos from
kernel space in linux ( I am making changes to the wavelan driver). Moreover
at the linux end I need to have kind of a handler which starts up as soon as
there is a packet or message to be read from a fifo and appropriately takes
action.
I would appreciate any ideas about how I could open close read write & do
something like a select on the RTfifos from kernel space. Alternatively is
there any other way I could approach the problem.
If anyone has tackled a similar problem or worked on using a wavelan with
RTL, your experiences would be of great help.
Thanks in advance,
Sugat Jain
