[Xenomai-core] First version for PCI framegrabber skeleton

First of all I would like to state I'm glad to write to this list once more :)

Secondly, I would like to apologize for the late that I'm sending you this first version of the
old promised skeleton for the real-time PCI framegrabber I've developed last year...

Thirdly, I would like to apologize for it being not organized nor documented, but I'll explain the
reasons for that.

Since I've finished my Master Thesis, I have been in a hurry and at this moment I'm working from
8h to 22h from monday to thursday and from 8h to 18h at friday in three different jobs... So, it
is true... I do not have time at the moment for writing the skeleton the way I want. But since I
received the message below yesterday (actually it was sent a week before but I didn't have time to
check my other mail), I tried to help him.

I tried to get some free time at my job today for organizing a bit and mainly for removing the
specific DataTranslation code from the skeleton because I do not have permission yet to send the
full code. I cannot assure the attached code will even compile, since I work on a Windows box at
work... Since I'm going to São Paulo tomorrow morning (6 am), in a business trip, I hope some of
you could assist him for any doubts due to code desorganization and lack of documentation...

Hope I can help with this code. Sorry, but I cannot do more than that until monday, when I come
back.

I'm missing some of you, specially Jan and Philippe who helped me a lot and were very kind during
my master thesis elaboration :)

Best Regards,

Rodrigo Rosenfeld Rosas.

Hello

I am driving a project for 4 french students : a box with Linux embedded 
and a usb camera. The embedded application will analyse the movies in 
Real time and lead a mobile machine with CAN-BUS. I use XENOMAI.
My problem is to write (i have no more than 1 month) the driver for 
Xenomai to drive the pci card.
My students have to write others parts of the programm.
I know that you have write this code.
I would be very happy to have this piece of code : it would be for me a 
beautiful beginning.

salutations

Your effort toward an RT framegrabbing driver interface is very welcome,
and I hope it can lay the ground for further work in this domain, also
via different media like FireWire or USB.

Just one issue remains as you already apologised for: this code needs a
/little/ bit cleanup. I tried to get an impression by browsing through
it, but it's fairly hard to read even for someone who thinks to know
what to look for. Too much experimental or dead code.

Maybe, once time permits, you can start the cleanup by reducing the
driver to a level that only leaves the removed HW access as markers,
killing everything that is not used right now in your real driver.

Jan
