Just learned that ARM9 processor can have MMU and no-MMU mode. Is that correct? So what are the consequences of having no-MMU - what are the implications in the "processes" architecture? Since paging figured so widely in the kernel, and without paging, everything is just physical address. Kernel and process address space - there is no longer switching among different "process" address space, and so meaningless to talk about "processes"? Are my analysis correct? What are the other consequences of no-MMU? -- Regards, Peter Teoh -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
