Function Documentation

◆ Napot()

uint32_t epmp_unittest::anonymous_namespace{epmp_unittest.cc}::Napot ( epmp_region_t region )

Encode a region using the NAPOT address mode.

This does not do any validation of the values provided.

Note: other address modes just require the address to be right shifted by 2.

Definition at line 302 of file epmp_unittest.cc.
