Linux 4.0 should be officially released within the next few weeks. In anticipation of its April debut, here's a look at some of the big features for this next version of the Linux kernel.
Announced today on the Linux kernel mailing list was the Library Operating System (LibOS) for Linux.
The BPF In-Kernel Virtual Machine will likely see new functionality with the next Linux kernel release cycle, Linux 4.1.
Linus Torvalds released the weekly release candidate to the Linux 4.0 kernel last night.
The HDMI CEC (Consumer Electronics Control) framework for the Linux kernel has been revived after being stalled in development for quite some time.
The fourth weekly release candidate to the Linux 4.0 kernel was just released for the newest round of Linux kernel testing.
Last year I wrote about a major performance breakthrough discovered for Intel's Linux graphics driver. That small but important patch for benefiting Intel Haswell graphics performance will be found with the upcoming Linux 4.0 kernel release.
KDBUS didn't make it for Linux 4.0 but version four of the KDBUS patches were posted today for review, which gives out hope we could see this in-kernel IPC interface based on D-Bus merged for Linux 4.1.
Linus Torvalds put out the Linux 4.0-rc3 release a short time ago as an "entirely normal" update for this stage of the kernel's release process of Linux 4.0.
A brand new networking stack is seeking to be merged into the mainline Linux kernel that's been under development for the past few years. Hello, Linux XIA.
David Airlie has started pulling in fresh Git code into DRM-Next for merging eventually with the Linux 4.1 kernel.
Linus Torvalds released the Linux 4.0-rc2 kernel this morning rather than on Sunday night due to having a i915 DRM graphics issue with one of his Apple Mac Mini computers. Aside from fixing up one of Torvalds' old systems, the Linux 4.0-rc2 kernel is a relatively mundane release.
BPF continues marching forward as a universal, in-kernel virtual machine for the Linux kernel. The Berkeley Packet Filter was originally designed for network packet filtering but has since been extended as eBPF to support other non-network subsystems via the bpf syscall. Here's some more details on this in-kernel virtual machine.
While the first release candidate of the Linux 4.0 kernel is barely one week old, Intel's open-source graphics driver development team already has changes queued up for the next kernel cycle, Linux 4.1
On top of the features mentioned in yesterday's article about features you won't find in the Linux 4.0 kernel like KDBUS and Tux3, there's also the Raspberry Pi VC4 DRM driver that has yet to be mainlined.
With last night's release of the Linux 4.0-rc1 kernel, Linus Torvalds changed the kernel codename from "Diseased Newt" to "Hurr durr I'ma sheep." While the codename may seem a bit odd, the Linux kernel codenames are generally quite awkward.
While Linux 4.0 is the next major kernel release and it does present a new lot of new functionality, there's still a number of high profile features not mainlined.
Linus Torvalds has decided to go ahead and rename the Linux 3.20 kernel to Linux 4.0 per his polling last week. Torvalds released Linux 4.0-rc1 on Sunday night and this release comes with many significant updates.
The nfsd changes for the Linux 4.0/3.20 kernel provide pNFS block server support.
Ingo Molnar has asked Linus Torvalds to pull the x86 platform support for Intel Quark SoC systems for the Linux 3.20/4.0 kernel.
While the Tamil driver is moving along for open-source ARM Mali T-Series graphics support, it could be a while before seeing the actual source code.
Last weekend I covered the changes so far for the next kernel release, which will be called either Linux 3.20 or Linux 4.0 depending upon Linus Torvalds' end decision. This week more exciting code has landed.
Chris Mason has sent in his pull request of the Btrfs file-system changes for the Linux 3.20 (4.0?) kernel.
The Linux Foundation has released their annual Linux kernel development report from the Linux Foundation Collaboration Summit taking place in Santa Rosa, California.
The next version of the Linux kernel, which will be known as Linux 3.20 or Linux 4.0, will land VirtIO 1.0 support.
Linus Torvalds has yet to reveal whether Linux 3.20 will be re-branded as Linux 4.0, but it seems the community at least really wants this version bump to happen.
The most recent pull request for the already very exciting Linux 3.20 / 4.0 kernel is the DRM graphics driver changes, which of course excite us a lot. This DRM pull request is another fairly heavy pull request with a number of end-user features for the popular open-source graphics drivers.
The latest pull requests sent in for the Linux 3.20 kernel are the various subsystems maintained by Greg Kroah-Hartman. The changes for the USB drivers, char/misc, driver core, staging, and TTY/serial aren't too jaw-dropping, but for staging at least is the usual heavy churn between kernel cycles.
While we don't yet know whether the next kernel version is Linux 3.20 or Linux 4.0, what we do know is that this next Linux kernel revision will contain a lot of exciting updates.
Linus Torvalds is still deciding when to bump the kernel version to Linux 4.0.
