Detailed Description

Translation Buffer Entry.

A translation buffer entry provides the mapping from a page of virtual memory to a page of physical memory.

Definition at line 501 of file AlphaCPU.h.

Data Fields
u64	virt
	Virtual address of page.
u64	phys
	Physical address of page.
u64	match_mask
	The virtual address has to match for these bits to be a hit.
u64	keep_mask
	This part of the virtual address is OR-ed with the phys address.
int	asn
	Address Space Number.
int	asm_bit
	Address Space Match bit.
int	access [2][4]
	Access permitted [read/write][current mode].
int	fault [3]
	Fault on access [read/write/execute].
bool	valid
	Valid entry.
