ARM and Linus Torvalds

Recently Linus Torvalds answered some questions at a Linaro Connect conference, one of them was wondering what his favorite processor architecture was, without babbling he answered: x86.

After the answer, Linus was asked why, especially because of the current popularity of the ARM architecture, which is used in a number of Android-based Smartphones, which in turn run the Linux kernel.

Torvalds commented that the x86's long history of life certainly helps him to have a privileged position in his concept. According to the creator of Linux, all this history causes little software and hardware fragmentation and "things just work".

For Linus, the infrastructure around the CPU matters more than itself:

What matters all the infrastructure around the instruction set, and x86 has all that infrastructure … on many different levels. Est took a path that no other architecture has yet managed to do., said Torvalds.

This explains some of the fragmentation of Android, where each specification is slightly different from the other, forcing developers to create device-specific kernel versions, according to Linus, the variety is so large that it may be the main reason there is no version of the kernel. Android that runs on all handsets without distinction.
