Moving mac68k to 8K pages?
Hi, m68k Mac fans,
After thinking about Izumi's recommendation to increase m68k usable
address space by increasing the page size from 4K to 8K, I decided to give
it a try on mac68k.
On a Quadra 605 which has 132 megs of memory I could reliably panic the
machine by trying to compile any of a number of different packages from
pkgsrc. After switching to 8K, this Quadra has been compiling for 22 days
straight without a panic.
I expect this will help with machines with even more memory. I have a
Quadra 630 with 196 megs and a quadra 610 with 260 megs, plus soon a
Quadra 800 with 520 megs.
Are there any good reasons to not switch mac68k to 8K pages, at very least
until someone gets around to rewriting the PMAP?
