Ok. Since you are asking me directly I am going to answer:
my point of view is, as I already told you, that MSI are not supported,
so still from my point of view the answer to question 1 is: "none"
Question 2 is yes, it is fine, but since MSI is not supported, it is not
supposed to work.
Answer to question 3 is that /proc/interrupts shows the interrupts
registered with request_irq whereas /proc/xenomai/irq shows the
interrupts which have been registered by xnintr_init, which
rtdm_request_irq uses. So, this is not the same code, the two files do
not have the same layout.
The reason why I did not answer is that Jan probably has a different
point of view for question 1, so, I let him answer you. But as far as I
know, Jan asked you some questions, in answer to your last post, to
which you did not answer.
