&os; now supports Symmetrical MultiProcessing (SMP) on a + variety of ARM multi-core systems. The effort to bring SMP to + ARM has been underway for quite some time, but a major push by + the &os; ARM developer community over the past two months has + resulted in robust production-ready SMP support.

+ +

An ever-growing number of ARM-based development boards and + small low-power computer systems are available with multi-core + processors. &os; is now able to make good use of all that + computing power, making such systems more attractive to both end + users and vendors looking to create products based on similar + designs.

+ +

SMP is now enabled by default in the configuration files for + all currently-supported systems that have multi-core processors. + This includes systems based on the following processor + families:

Allwinner A20
Freescale i.MX6
Marvell Armada XP
Samsung Exynos 5
