Direct Segment

This translation hardware models a direct-segment-like translation scheme.

Description

The direct segment is a single, continuous address range controlled by three 64-bit registers. The region must be between 4G and 128TB, and must be aligned to 16 bytes.

VABase The base address of the virtual region covered by the direct segment.

Size The size of the region should be aligned to 16 bytes. A size of 0 disables translation.

DstBase The destination region must be within the available 46-bits of physical addresses, and should be 16 bytes aligned.

Register Accesss The registers are special CPU registers that can be accessed using load/stores (e.g., mov rax vabase).
