Amiga & AROS Version 1.3.2 of the Icaros Desktop is now available. Icaros Desktop is one of the prime AROS distributions, ready to be used on your desktop today - no fancy PowerPC hardware required (like with AmigaOS or MorphOS). If I can get this running, it might be about time we took a closer look at this, don't you think? Thoughts?

No, memory protection hurting performance isn't a big worry among AROS devs or users. The real issue is finding a way to introduce it without breaking source compatibility (too much).

ncafferkey,

"No, memory protection hurting performance isn't a big worry among AROS devs or users. The real issue is finding a way to introduce it without breaking source compatibility (too much)."

I know very little about this platform, but I'm curious what kind of software requires the absence of memory protection? Is this because amiga apps routinely access hardware directly? Or they routinely read/write bios/os structures?

AmigaOS is a Single Address Space OS, where an App or OS can pick any object of other applications. That makes data passing and sharing easy and fast. As I see it, the only way to do memory protection transparently is protection domains that require tagged memory allocations to specify data access rights.
