Linux kernel LTSI

Linux kernel LTSI is an open source collaborative project started and hosted by The Linux Foundation in order to create and maintain a basic Linux kernel package that can be used in various consumer electronic products.

The LTSI Linux kernel has been created by some of the most important electronic manufactures in the world, including Sony, LG Electronics, Panasonic, Hitachi, NEC, Qualcomm Atheros, Samsung Electronics, Renesas Electronics Corporation, and Toshiba

The heart of every GNU/Linux distribution

Linux Kernel is the most essential part of a GNU/Linux operating system, the heart of every distribution, responsible for resource allocation, security, low-level hardware interfaces, basic file system management, as well as simple communications.

Linux is a clone of the UNIX operating system. It was written from scratch by Linus Torvalds, an American-Finnish hacker, with assistance from a loosely-knit team of hackers across the Internet.

Supported on a wide range of hardware platforms

While it was initially engineered to work only with 386/486-based computers, the Linux kernel is now supported on a wide range of hardware platforms, including 64-bit (IA64, AMD64), ARM, ARM64, DEC Alpha, MIPS, SUN Sparc, PowerPC, as well as Amiga and Atari machines.

Linux kernel provides very powerful features, among which we can mention true multitasking, shared libraries, multistack networking, demand loading, shared copy-on-write executables, proper memory management, as well as virtual memory.

The most essential component of a GNU/Linux operating system

We said it once and we say it again: Linux kernel is he most essential component of a GNU/Linux operating system. Without it, the entire system, which comprises of libraries, applications, etc., is completely useless.

When creating a device powered by Linux kernel, it is very important to know how to correctly optimize it for that device, be it a phone, tablet or a smart TV, in order to make it support certain hardware components and functions.

What is new in this release:

• Updated to upstream Linux kernel 3.10.25

What is new in version 3.4.25:

• The Contiguous Memory Allocator (CMA), which is extremely useful for embedded devices that have very limited hardware resources and will better handle the large memory requirements of multimedia applications. CMA originally was merged into the 3.4.0 kernel release, but its functionality was quite limited. Since then, the feature has been significantly improved in the kernel.org releases and those fixes have been added to the LTSI 3.4 kernelrelease. For more information about this kernel option, please visit LWN.net.
• AF_BUS, a kernel-based implementation of the D-Bus protocol. This feature was created for systems that required a faster D-Bus speed than the existing userspace method could provide, specifically the automotive entertainment systems. For more information about this feature, please see LWN.net.
• CoDel (controlled delay), a transmission algorithm that optimizes TCP/IP network buffer control, is backported for LTSI 3.4. This is a feature used to help control the "buffer bloat" problem that has been identified by the networking community as an issue that all devices need to be aware of. This feature was backported from the 3.5.0 kernel.orgrelease.
