Adeos's role w.r.t Linux
- by Anisha Kaul
The event pipeline The fundamental Adeos structure one must keep in
mind is the chain of client domains asking for event control. A domain
is a kernelbased software component which can ask the Adeos layer to
be notified of:
· Every incoming external interrupt, or autogenerated
virtual interrupt; ·
Every system call issued by Linux applications, ·
Other system events triggered by the kernel code (e.g. Linux task switching, signal notification, Linux task exits etc.).
From: Life with Adeos: http://www.xenomai.org/documentation/xenomai-2.4/pdf/Life-with-Adeos-rev-B.pdf
Question: Adeos is supposed to be between the hardware and the Linux kernel, I can understand about Adeos telling the Linux about hardware interrupts but Why should Adeos know about the "system call" issued by Linux?
