Dear,
As known, the norm arinc653 is very strict and the API proposed should
be respected. Some functions of the API need more than five arguments.
However, the "SKINCALL" is limited to 5. If I want to increase, I have
to modify the following files :
- ./xenomai-2.5.6/include/asm-arm/syscall.h
- ./xenomai-2.5.6/include/asm-blackfin/syscall.h
- ./xenomai-2.5.6/include/asm-x86/syscall.h
- ./xenomai-2.5.6/include/asm-powerpc/syscall.h
- ./xenomai-2.5.6/include/asm-nios2/syscall.h
Is it possible? Is is a good idea ?
Thank you for your attention and your help.
Sincerely
Omar ZENATI

No, dead end. You should group arguments in a struct and pass the
address of such struct to kernel land for decoding.

Dear,
I have implement a first version of the skin Arinc 653. However, I match
one bug. Each time I execute a test I have implemented (Hello world
test). The process display "Hello world!" but don't return and even if I
do control-z or control-c the process don't terminate.
have and idea to fix this problem??
Thank you for your help.
Sincerely
Omar ZENATI

It is hard to say anything witout seeing any code, but, when you hit
ctrl-C or ctrl-Z, the process receives a signal SIGINT or SIGTSTP. So,
in the implementation of this skin, did you handle the interruption of
blocking system calls by a signal correctly ?

No I don't implement any handler, but there isn't a handler by default?
I don't see any handler of signals in the sources of others skins. it
means that I have to implement a handler in source of the test?

We do not understand your issue, you do not understand our answers,
please show us the code to avoid further misunderstandings.
