Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

Are these kinds of questions considered off-topic? What else can be the reason that I have received 3 downvotes?

Adeos's role w.r.t Linux

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

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?

This probably could be considered on-topic, but not in the way you asked it. If your question is simply, "Why would the Adeos nanokernel need to intercept system calls?", then lead with that - make that your title, explain your confusion, and then link to some background information on Adeos.

The way it reads here, I have a bit of trouble determining if your question is concerned with understanding how system calls / software interrupts matter when the purpose of Adeos is to share hardware resources... Or if you're just struggling to interpret the text on the Adeos web page.

It's important that when you ask a question you strive to make it clear up-front what that question is. Don't expect folks to do a whole lot of research before deciding whether or not your question is on-topic - and if you do make them do so, expect down-votes for being unclear. As a rule of thumb, your title should summarize your question.

I'd suggest you edit your question on SU for clarity then. Don't re-post. – Shog9 Apr 2 '12 at 6:28
