unix - xv6 KERNBASE limitation of process memory -


there question in xv6 book bothers me long time, , wondered if clarify on this

kernbase limits amount of memory single process can use, might irritating on machine full 4 gb of ram. raising kernbase allow process use more memory?

in opinion answer question no, since whole mechanism around xv6 designed work kernbase on specific address space.

thanks answer.

well, there issue here.

all physical addresses supposed used mapped virtual addresses 0x80000000 , up.

so, if move kernbase upawards, os can use less physical memory.
