Long Term Support Initiative (LTSI)
About Long Term Support Initiative (LTSI)
LTSI is an industry-wide project created and supported by Hitachi, LG Electronics, NEC, Panasonic, Qualcomm Atheros, Renesas Electronics Corporation, Samsung Electronics, Sony and Toshiba and hosted at The Linux Foundation to maintain a common Linux base for use in a variety of consumer electronics products. The project creates and maintains a long-term industry tree, which is expected to be stable in quality for the typical lifetime of a consumer electronics product, typically 2-3 years.
This new initiative is crucial because device makers are doing significant back-porting, bug testing and driver development on their own, which carries substantial cost in terms of time-to-market, as well as development and engineering effort to maintain those custom kernels. Through collaboration in this initiative, these CE vendors will reduce the duplication of effort currently prevalent in the consumer electronics industry.
The LTSI tree is expected to be a usable base for the majority of embedded systems, as well as the base for ecosystem players (e.g., semiconductor vendors, set-vendors, software component vendors, distributors, and system/application framework providers). The LTSI project will combine the innovative features in newer kernels needed by CE vendors with a stable kernel, while helping those vendors get their code upstream to benefit the entire Linux community. The goal is to reduce the number of private trees currently in use in the CE industry and encourage more collaboration and sharing of development resources.
Overview of LTSI
The LTSI project is an industry-wide collaborative activity to minimize fragmentation, and accelerate further innovation of Linux by incorporating fixes and innovations from embedded system engineers. The LTSI project consists of three major activities as follows.
LTSI is a collaborative developement effort by member companies. Also, collaboration with other open source projects is the key enabler for LTSI to be fully utilized by the industry. Here are some of the elements of the LTSI ecosystem.
