M68K: Life in the Old Architecture

The Motorola 68000 architecture is a "classic". It has been around for a very long time, and during the 1980's was a serious competitor to the Intel family of x86 processors. Where is it today? Turns out it is still alive in a new form, the ColdFire family of processors. And Linux support is pretty good for these. In fact it is still quite active. This old architecture is still quite alive. A lot has been happening in the m68k architecture code in Linux over the last year. Much merging of code and new support for MMU hardware is going on. This presentation will have a look at the history and status of the m68k/ColdFire support in the kernel, and where it is going.
