Linux Kernel 4.0 Features Live Kernel Patching, PS3 Support
|
|
||||||
================================================================================
|
|
||||||
|
|
||||||
|
|
||||||
**A new stable release of the Linux Kernel [has been announced][1] by Linus Torvalds on the Linux kernel mailing list. **
|
|
||||||
|
|
||||||
Linux 4.0, codenamed ‘Hurr durr I’m a sheep’ — no, really — brings with it a small set of new hardware support, driver improvements, performance tweaks, bug fixes and the like.
|
|
||||||
|
|
||||||
But remarking on the minor-ness of the update, Torvalds’ writes;
|
|
||||||
|
|
||||||
> “Feature-wise, 4.0 doesn’t have all that much special. Much have been made of the new kernel patching infrastructure, but realistically […] we’ve had much bigger changes in other versions. So this is very much a “solid code progress” release.”
|
|
||||||
|
|
||||||
Linus adds that Linux 4.1 is likely to be a ‘bigger release’.
|
|
||||||
|
|
||||||
### New Linux Kernel 4.0 Features ###
|
|
||||||
|
|
||||||
Install Kernel Updates Without Rebooting
|
|
||||||
|
|
||||||
If you’ve ever been put out by the need to reboot your Linux box to finish installing a kernel update you won’t be alone. It’s a minor inconvenience on the desktop, and a major one for servers.
|
|
||||||
|
|
||||||
|
|
||||||
Reboot-free Kernel Updates
|
|
||||||
|
|
||||||
The ability to install/apply security patches to the Linux kernel “live”, without the need to reboot, has been a long-held want of many Linux enthusiasts for years.
|
|
||||||
|
|
||||||
A slew of third-party projects, like [Oracle’s KSplice][2] and Red Hat’s Kpatch, have sought to offer live patching functionality for certain distributions.
|
|
||||||
|
|
||||||
For servers, enterprise and mission-critical use cases where uptime is priority live kernel patching is a pretty big deal.
|
|
||||||
|
|
||||||
The good news is that Linux 4.0 makes having to reboot to complete a kernel update a thing of the past.
|
|
||||||
|
|
||||||
Well, almost.
|
|
||||||
|
|
||||||
The initial groundwork to support reboot-free patching arrives in this latest release, ready for experienced sysadmins to take advantage of in Linux 4.0.
|
|
||||||
|
|
||||||
Desktop Linux distributions should also be able to take advantage of the feature too (though given the complexity involved in configuring the reboot-less functionality on the end-user side it may be a little way off).
|
|
||||||
|
|
||||||
This infrastructure will continue to be refined and improved on over the course of the 4.x series. As it does so I expect we’ll all start to hear more about it.
|
|
||||||
|
|
||||||
#### Other Changes ####
|
|
||||||
|
|
||||||
Although it is considered a small release the latest Linux kernel manages to squeeze in a welcome set of hardware improvements, new drivers and performance tweaks. These include:
|
|
||||||
|
|
||||||
|
|
||||||
- Improvements to Intel ‘Skylake’ platform
|
|
||||||
- Intel Quark SoC support
|
|
||||||
- Various patches to improve Linux running on a Playstation 3
|
|
||||||
- TOpen-source AMD Radeon driver supports DisplayPort Audio
|
|
||||||
- Various misc HID driver tweaks, including Lenovo compact keyboards, Wacom Cintiq 27QHD
|
|
||||||
- Toshiba power settings driver adds USB sleep/charge functionality, rapid charge, sleep w/ music, etc
|
|
||||||
- File System tweaks, including F2FS, BtrfFS, etc
|
|
||||||
|
|
||||||
### Install Linux Kernel 4.0 on Ubuntu ###
|
|
||||||
|
|
||||||
Although classed as stable there is, at present, **no need for desktop users or new-comers to go upgrade**.
|
|
||||||
|
|
||||||
The impatient and adept can take a crack at installing Linux 4.0 in Ubuntu 15.04 Beta by grabbing the appropriate set of packages from [Canonical’s mainline kernel archive][3] or by risking a third-party PPA hosted on Launchpad.
|
|
||||||
|
|
||||||
Ubuntu 15.04 Vivid Vervet is due later this month and will ship with Ubuntu Kernel 3.19 (the Ubuntu kernel is the Linux Kernel plus Ubuntu-specific patches that have not been accepted upstream).
