Also here: Do not misuse write(), define an IOCTL that contains
something like "MMAP" and another one with MUNMAP in its name - that's
the purpose of this service, no?
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 ?
Thank you for your help,
Jerome
