Fault GenericTLB::finalizePhysical | ( | RequestPtr | req, |
ThreadContext * | tc, | ||
Mode | mode | ||
) | const |
Do post-translation physical address finalization.
This method is used by some architectures that need post-translation massaging of physical addresses. For example, X86 uses this to remap physical addresses in the APIC range to a range of physical memory not normally available to real x86 implementations.
req | Request to updated in-place. |
tc | Thread context that created the request. |
mode | Request type (read/write/execute). |
