10.6 Snow Leopard PowerPC Development

[ChrisCharman]

Hate to join in randomly to nitpick, but.... is the snow leopard image used for the first post... AI generated???

Yes it is. You’re not going mad don’t worry.

Darn! I really like that image... I think a little less of it if it is AI generated.

This may be a dumb question, but to clarify does the kernel actually support 64-bit addressing at the system level for the G5 systems? As in, can this kernel address more than 4GBs of RAM? IDK why but this question has been itching in the back of my brain because I just assumed we would get a 64-bit kernel for G5s but I am not so sure now.

The kernel is 32-bit but it can run 64-bit processes.

Virtual Memory can probably handle sharing of memory between 32-bit kernel and 64-bit app.
I think DART can handle DMA from hardware to 64-bit addresses.
