Member Function Documentation

◆ translate()

void gem5::EmulationPageTable::PageTableTranslationGen::translate ( Range range) const

Subclasses implement this function to complete TranslationGen.

It should accept a Range reference which will have its "vaddr" field set to the virtual address to translate, and the "size" field set to the remaining size of the entire region being translated.

If there is a fault performing the translation of "vaddr", then this function should set the "fault" field of range and return.

If the translation was successful, this method should set "paddr" to the corresponding physical address, and set "size" to the number of bytes corresponding to the translation. Or more precisely, size should be set to the maximum "N" where vaddr + n maps to paddr + n for all 0 <= n <= N.

Implements gem5::TranslationGen.
