CPU feature checking - require neon
The packages in the isa-support family probe for microprocessor Instruction Set Architecture features such as SSE3. By refusing to install on machines lacking a required feature, they allow ISA requirements to be handled in terms of package dependencies.
This is a mostly dummy package which checks for neon and refuses to install on unsupported hardware.

Neon, also known as MPE (Media Processing Engine) or Advanced SIMD, is a combined 64- and 128-bit SIMD instruction set that provides standardised acceleration for media and signal processing applications. It is available on the vast majority of armhf devices but not guaranteed before the 64-bit capable ARMv8.
