December 21st, 2013
  • Updated to upstream Linux kernel 3.10.25

New in version 3.4.25 (January 22nd, 2013)

  • 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.
