POWER DOWN
Jon Masters is a kernel hacker who’s been involved with Linux for over 22 years.
A recent patch series removed support for the IBM PowerPC 405. If you worked on embedded Linux devices around the turn of the century, you will have encountered many of these. They were (briefly) everywhere back in the twilight years of the PowerPC architecture. This was a time before Apple had moved to x86 (and ultimately, Arm), when PowerBooks were called such because they had PowerPC processors inside. I was a huge fan of the PowerPC architecture at the time, since it was RISC-based and used in my first big commercial embedded Linux projects – a piece of scientific instrumentation.
