Android devices are based on the Linux kernel but, since the beginning, those devices have not run mainline kernels. The amount of out-of-tree code shipped on those devices has been seen as a problem for most of this time, and significant resources have been dedicated to...

Device trees have become ubiquitous in recent years as a way of describing the hardware layout of non-discoverable systems, such as many ARM-based devices. The device-tree bindings define how a particular piece of hardware is described in a device tree. Drivers then...
The results of the 2018 election for members of the Linux Foundation's Technical Advisory Board have been posted; the members elected this time around are Chris Mason, Laura Abbott, Olof Johansson, Dan Williams, and Kees Cook. Abbott and Cook are new members to the board...
Stable kernels 4.19.2, 4.18.19, 4.14.81, and 4.9.137 have been released. They all contain a relatively large set of important fixes and users should upgrade.

Debian supports many architectures and, even for those it does not officially support, there are Debian ports that try to fill in the gap. For most user applications, it is mostly a matter of getting GCC up and running for the architecture in question, then building all of...

User-space developers may be accustomed to thinking of system calls as direct calls into the kernel. Indeed, the first edition of The C Programming Language described read() and write() as 'a direct entry into the operating system'. In truth, user-level 'system calls' are...

Since the beginning, one part of the kernel-development task has been watching the mainline to see whether one's work had been merged. That is about to change with the advent of the pull-request tracker bot, which will inform maintainers when one of their pull requests has...
As a general rule, the kernel is supposed to use the least amount of CPU time possible; any time taken by the kernel is not available for the applications the user actually wants to run. As a result, not a lot of thought has gone into optimizing the execution of kernel-side...
