Subject: [Xenomai-core] Cannot end interrupt from user space: add rt_intr_end call ?
Date: Thu, 24 Apr 2008 00:33:05 -0400	[thread overview]
Message-ID: <48100D81.9090109@domain.hid> (raw)


Hi,

I think that when I handle interrupts from user space, I cannot 
correctly use I_NOAUTOENA. The thing is that this flag in fact means "do 
not call automatically xnarch_end_irq". The xnarch_end_irq call usually 
maps to unmasking the interrupt, but not always - depending on interrupt 
type (sometimes in eoi, sometimes is nop).

I was thinking that it would be nice if I could call something like 
"xnarch_end_irq" (i.e. rt_intr_end) from user space, so that I could 
correctly use I_NOAUTOENA to control the flow of interrupts.

Cheers,
Tomas
