Linaro is an engineering organization that works on free and open-source software such as the Linux kernel, the GNU Compiler Collection (GCC), power management, graphics and multimedia interfaces for the ARM family of instruction sets and implementations thereof as well as for the Heterogeneous System Architecture. The founding of Linaro was announced at Computex in June 2010 by ARM, Freescale Semiconductor, IBM, Samsung, ST-Ericsson, and Texas Instruments in a joint press conference. It also provides engineering and investment in upstream open source projects, a monthly release of tools and software and support to silicon companies in upstreaming code to be used with their system-on-a-chips (SoC). At some point Linaro joined the HSA Foundation.
