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 ?
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 ?
Use the LDLIBS variable when linking the library?
Gilles,
you're right ;-), I didn't use LDLIBS for linking the library, therefore
I corrected this.
Now I have this as link line for my library :
gcc -shared -Xlinker -rpath -Xlinker /usr/xenomai/lib
-I/usr/xenomai/include/include/xenomai
-I/usr/xenomai/include/include/xenomai/compat
-I/usr/xenomai/include/include/xenomai/posix -I./ -I.//Toolkit
-Wl,@/usr/xenomai/lib/posix.wrappers -L/usr/xenomai/lib -lpthread_rt
-lxenomai -lpthread -lrt -o libcifx.so .//cifXDownload.o
.//cifXEndianess.o .//cifXFunctions.o .//cifXHWFunctions.o .//cifXInit.o
.//cifXInterrupt.o .//md5.o .//cifx_xenomai.o .//OS_xenomai.o
.//USER_xenomai.o
and this for the application :
gcc -DCONSUMER -I/usr/xenomai/include -D_GNU_SOURCE -D_REENTRANT
-D__XENO__ -I/usr/xenomai/include/posix -I../libcifx
-I../libcifx/Toolkit -O2 -lcifx -lpciaccess -lrtdm -Xlinker -rpath
-Xlinker /usr/xenomai/lib cifx_xenomai_sample.c
-Wl,@/usr/xenomai/lib/posix.wrappers -L/usr/xenomai/lib -lpthread_rt
-lxenomai -lpthread -lrt -lcifx -lpciaccess -lrtdm -o cifx_xenomai_sample
with
mlockall(MCL_CURRENT | MCL_FUTURE);
first line in main
I have a new log :
[ 4700.073616] cifx 0000:04:01.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
[ 4700.073643] cifx 0000:04:01.0: DPM at FEBF0000

[ 4751.104009] rt
[ 4751.388002] Xenomai: Posix: destroying mutex f8419600.
But as you see It seems I'm always in Non Real Time mode...
Do you have an idea about my problem ?
The log "rt" and " Xenomai: Posix: destroying mutex f8419600." is normal ?
Thank you for your help,
Jerome
