/**
|
||||
* Address space layout.
|
||||
*
|
||||
* RISC-V implements up to a 48 bit virtual address space. The address space is
|
||||
* split into 2 regions at each end of the 64 bit address space, with an
|
||||
* out of range "hole" in the middle.
|
||||
*
|
||||
* We limit the size of the two spaces to 39 bits each.
|
||||
*
|
||||
* Upper region: 0xffffffffffffffff
|
||||
* 0xffffffffc0000000
|
||||
*
|
||||
* Hole: 0xffffffffbfffffff
|
||||
* 0x0000000080000000
|
||||
*
|
||||
* Lower region: 0x000000007fffffff
|
||||
* 0x0000000000000000
|
||||
*
|
||||
* We use the upper region for the kernel, and the lower region for userland.
|
||||
*
|
||||
* We define some interesting address constants:
|
||||
*
|
||||
* VM_MIN_ADDRESS and VM_MAX_ADDRESS define the start and end of the entire
|
||||
* 64 bit address space, mostly just for convenience.
|
||||
*
|
||||
* VM_MIN_KERNEL_ADDRESS and VM_MAX_KERNEL_ADDRESS define the start and end of
|
||||
* mappable kernel virtual address space.
|
||||
*
|
||||
* VM_MIN_USER_ADDRESS and VM_MAX_USER_ADDRESS define the start and end of the
|
||||
* user address space.
