The "eXt73" patch-set aspires to yield faster kernel performance and better power efficiency. Independent benchmarks published of the eXt73 patch-set indicate faster performance out of the patched Linux kernel, but these patches do come at a cost for end-users.
The latest Linux 3.19 kernel changes to talk about is the staging pull request that was sent in a short time ago by Greg Kroah-Hartman.
We're now half-way through the Linux 3.19 kernel merge window so here's a recap of the most interesting features that have been merged thus far for what will become the first major Linux kernel release of 2015.
One week into the merge window for the Linux 3.19 kernel, the DRM subsystem pull request was sent in this morning by Red Hat's David Airlie. There's a lot of interesting kernel graphics driver changes abound for Linux 3.19!
The Linux 3.19 kernel is set to introduce support for the CoreSight framework and implementations for a few SBC boards.
Within the in-development Linux 3.19 kernel is now support for LZ4 compression for SquashFS, the read-only file-system commonly used by various Linux distribution live CDs.
The multi-queue block layer (blk-mq) will be in even better shape with the upcoming Linux 3.19 kernel.
Beyond the DRM graphics improvements for Linux 3.19 affecting the most common kernel graphics drivers, the STI driver will too see improvements for this next kernel version.
The latest pull request of interest to us for the Linux 3.19 merge window is the sound driver updates.
We've been talking about Intel MPX support in the kernel for one year and with the upcoming Linux 3.19 kernel that support is finally being realized.
Another one of the interesting early pull requests for the Linux 3.19 kernel is the Device Mapper changes.
OverlayFS was finally merged in Linux 3.18 and now for the Linux 3.19 merge window it's picking up another feature.
Rafael Wysocki of Intel mailed in the ACPI and power management changes for the Linux 3.19 merge window. As said by the ACPI/PM subsystem maintainer, "This time we have some more new material than we used to have during the last couple of development cycles."
As anticipated, Linus Torvalds officially released the Linux 3.18 kernel this Sunday evening.
Besides the many Linux graphics driver changes for Linux 3.19, there's many other non-graphics features out on the horizon in kernel land -- some of which might land in Linux 3.19 but most of the other items are post-3.19 material. Linux 4.0 also isn't likely far out.
Here's some more Linux 3.18 kernel benchmarks I did with the final release due out likely today. However, these results seem to be a bit odd.
With Linux 3.18 likely coming out today, we can begin focusing more of our attention and testing on the code that will become the Linux 3.19 kernel over the weeks ahead. Once again, when it comes to the DRM graphics driver changes, there's lots of exciting improvements.
The Linux 3.18 kernel is expected to be released this weekend and with this major update to the kernel are -- as usual -- an exciting number of changes and new features.
Linus Torvalds is looking at officially releasing the Linux 3.18 kernel in one week.
When Linux 3.18-rc6 was released last Sunday, Linus Torvalds noted in the release announcement that a "a big unknown worry in a regression" remained. Nearly one week later, kernel developers are still figuring out what's going on with this regression that can cause frequent lockups. Worse off, it looks like it might affect the Linux 3.17 kernel too.
Linus Torvalds put out his usual weekly release candidate to the Linux 3.18 kernel.
Earlier this week on Phoronix I posted benchmarks indicating potential block/file-system performance regressions using the Linux 3.18 kernel. Since then I've been carrying out more tests looking for any file-system performance problems on other hardware.
The second revision to the Linux kernel based D-Bus implementation is now available for review.
Rob Clark on Sunday submitted his "msm-next" pull request for the DRM-Next Git tree for pulling into the Linux 3.19 kernel.
In traditional manner Linus Torvalds announced the Sunday afternoon release of the latest Linux kernel development build.
While the Linux kernel is constantly improving, it cannot yet be built as C11 code.
While Linus Torvalds was a bit unhappy about the continued flow of late changes for the Linux 3.18 kernel, with today's 3.18-rc4 release he's happy that the past week has indicated a slowdown in changes for Linux 3.18.
Stephan Mueller has announced the first release of libkcapi, a user-space library for tapping the Linux kernel's crypto API in an easy-to-use fashion.
Back in February SUSE unveiled a new means of live Linux kernel patching, kGraft, compared to the existing Ksplice. One month later, Red Hat unveiled their own solution that happened to be under development at the same time, Kpatch. Since both of them have been out, both have pursued mainline interests but neither one accepted upstream yet. Now a new live kernel patching solution is out that tries to take the best of both worlds.
Red Hat's David Airlie as the Linux kernel's subsystem maintainer has written a status update about his plans and thoughts for DRM graphics driver changes for the next kernel cycle, Linux 3.19.
