Based on Linux 3.4.25, the LTSI 3.4 is equipped with features such as Contiguous Memory Allocator (CMA) which is helpful for embedded devices with limited hardware resource availability; AF_BUS – a kernel-based implementation of the D-Bus protocol; CoDel (controlled delay) – a transmission algorithm meant for optimization of TCP/IP network buffer control.

Fragmentation and separate research initiatives were the norm up until now when it came to Linux in the consumer electronics industry. Vendors were having their own research teams to implement Linux in consumer electronics and with a life-span of two years vendors were always busy “back-porting, bug testing and driver development on their own” thereby incurring heavy costs and “substantial cost in terms of time-to-market”, notes the LTSI 3.4 release announcement.

In a bid to address this issue the LTSI was founded by The Linux Foundation’s Consumer Electronics (CE) workgroup. LTSI project, backed by the likes of Hitachi, LG Electronics, Qualcomm Atheros, Samsung Electronics, Sony and Toshiba, releases both annual versions of stable kernel Linux as well as regular updates for two years for a particular version.
