Learn more at https://events.linuxfoundation.org/ 32-bit Linux Support Now and in the Future - Arnd Bergmann, Linaro Over the last few years, 64-bit Linux has made it from Servers, PCs and high-end embedded machines lower down in the market, everywhere including the smallest embedded Linux targets. This gives new challenges for users that rely on existing 32-bit hardware being kept up to date, while new features development and testing on those machines keeps winding down. Arnd gives an overview of which 32-bit systems are still supported, and how long that is going to be the case. This covers modern ARMv7/v8 hardware, older ARMv4/v5/v6 machines, and other embedded CPU architectures. Specific issues include MMU-less microcontrollers, large memory, small memory, 32-bit userland on 64-bit hardware and the state of the 2038 epochalypse.
