8 architectures will disappear from the Linux kernel

Posted by UDS Enterprise Team |

The developers of Linux are working to eliminate the kernel eight architectures and their corresponding drivers from next version of Linux. It is a necessary task for optimal maintenance since the following CPU architectures are considered obsolete:


Blackfin: a family of 16 and 32-bit microprocessors developed by Analog Devices. It is used in embedded systems, in the processing of digital signals. It is found in telescopes or home cinema devices.

ETRAX Cris: Axis Communications manufactures these microprocessors designed to use in embedded systems.

FR-V: processor developed by Fujitsu used in digital cameras of brands such as Leica, Nikon, Pentax or Sigma.

META: the incompatibility with the modern versions of the GCC compiler and the scarcity of users that use it have caused this multi-threaded 32-bit architecture to be removed from the kernel.

M32R: digital cameras and PDAs use this 32-bit RISC architecture as an embedded system. It is currently left without maintenance and hence it will be removed.

MN10300: is part of 32-bit microprocessors manufactured by Panasonic. They are usually found on DVD players or digital cameras.

Tile: multi-core processor used in on-chip systems to carry out mesh network connections.

Score (S + core): proprietary architecture developed by Sunplus Technology. It is incompatible with modern versions of GCC and has become obsolete.

Most of these architectures are eliminated by the lack of developers that keep them updated in the kernel. The low popularity and incompatibility with the construction modes of the most recent versions of the kernel are other reasons that have favored the decision to remove them from the next Linux 4.17.
