Hardware, Embedded Systems This is a situation where I need the help of you OSnews readers who are experienced with low-level development on ARM, SPARC, PowerPC, MIPS, and other hardware architectures we have on computers nowadays. The issue is that I'm currently designing the part of my hobby kernel which takes care of interrupts. Although I mostly work on x86 at the moment, I'd like to keep this code portable to other hardware architectures in the future. To do that, I have to know how interrupt handling works on as much HW architectures as possible.

Nah I agree :-) I believe to have acknowledged that polling is not adapted anymore in my previous post, but probably not really clearly. It's just that I think it's good to question past decisions and not always blindly build on top of it. Your approach of building an OS is a testament that you are on the same camp :-)

I know, now... At the time I redacted that comment, I should have turned off my computer for an hour or two, and my brain wasn't working properly anymore ;)

Sole thing which remains not perfectly clear after a night of sleep is this:

Are you talking about how I build mine in particular, or about the idealized (and I hope improved) version of this building process which I preach in the "Hobby OS-deving" series, as opposed to the "tutorial" approach ?

No worries, that's the curse of writing an osnews article, so many comments to answer :-p For the last bit I just means that by writing an OS you're revisiting past decisions in some way.
