Memory-mapped I/O without mysterious macros
<i>While I&#x2F;O memory looks like memory, and it can be tempting to access it by simply dereferencing a pointer, that does not always work on every architecture</i><p>Unfortunate that there&#x27;s no examples, because that sounds more like something which is not actually MMIO (like the I&#x2F;O space on x86) or a bug, since one of the reasons for using MMIO is that it behaves like memory.
