Also here: Do not misuse write(), define an IOCTL that contains
something like "MMAP" and another one with MUNMAP in its name - that's

A lot of drivers probably have to reinvent a way to pass all the
parameters for an mmap, why not adding an "mmap" method to RTDM drivers?
Hello,
I re factored my code with all your remarks (I think and I hope).
Could you say me if it's correct now ?
Jan, you're right, It's possible to use Xenomai with UIO driver, but I
would like to use more real time possibilities of Xenomai in future
(like IRQ).
My first goal is to have a code compliant.
I added IRQ, and my next step will be to understand why the kernel
crash after IRQ registration.
Thank you for your help,
Jerome
Hello,
I have good news because, I arrived to validated driver with IRQ
support. I changed position of cifx on my motherboard in my PC and the
IRQ affected is not shared ;-) !
I have now a question about IRQ. What is the good method to signal to
user-land that there is an IRQ. Is there an example ?
Almost every "read" call is an example... ;-)
Hello,
I'm finishing my driver with IRQ. I saw that there is two mode, Real
time and Non real time for RTDM driver function.
My driver should run in the two mode. When I compile my User Space
Shared library that call Xenomai Kernel driver,
I saw that library call every time Non real time function and no real
time function...
I use a shared library with posix skin with makefile in attached file. I
read explanation for static library with posix skin :
http://www.xenomai.org/index.php/Porting_POSIX_applications_to_Xenomai
What must I do with shared library for using rt mode ?
