Query: Paged/NonPaged

NTDEV
1

Hi,

I read that windows NT divides the kernel-mode address space into
paged and nonpaged memory pools.

If I have a 32 bit address bus, then I would get 2GB kernel address
space. So, how much would be allocated for paged and nonpaged ?

And what if the paged memory runs out of space ?

Please answer to my queries.

Thanks,
Vinay

Around 256MB nonpaged, maybe around 512MB paged.

And what if the paged memory runs out of space ?

Allocations start to fail.
