Yeah... I suppose I wasn't paying close enough attention to what you |
6 |
were saying. :-) |

The VMSPLIT options are about how the kernel uses the 32 bit address |
9 |
space (specifically, what fraction of the address space of each process |
10 |
it reserves for its own use). A large portion of what a 64 bit system |
11 |
gets you is more than 32 bits worth of address space, so I'm fairly sure |
12 |
the entire issue is moot. :-) |

(On the other hand, I have still yet to look really closely at the gory |
15 |
details of how AMD64 works, and how linux uses it. I had a decent idea, |
16 |
way back when the only implementations available were simulators, but |
17 |
that was a while ago and I've forgotten a lot of it. As such, I might be |
18 |
wrong.) |
