With week one of two having passed for the Linux 4.2 kernel merge window, here's a look at some of the exciting new features and changes that landed in the first week.
Non-volatile memory device support will be added through libnvdimm for the Linux 4.2 kernel. Libnvdimm is a new subsystem for the Linux 4.2 kernel and contains drivers and x86 support.
For those using the Global File System 2 (GFS2) for Linux clusters, the Linux 4.2 kernel is slated to offer better performance.
While Greg Kroah-Hartman isn't sending in KDBUS for Linux 4.2 as announced yesterday, he did send in the code updates for the other kernel subsystems he maintains.
KDBUS was once again heavily debated on the Linux kernel mailing list this week and Linus Torvalds said he looked forward to merging it when ready (and also had some choice words about performance). However, Greg KH has confirmed today that KDBUS isn't ready for merging this cycle.
David Airlie has sent in the main DRM driver updates for the Linux 4.2 kernel. There's a lot of open-source graphics driver work represented by this pull request, but sadly no Nouveau (open-source NVIDIA) changes were incorporated for Linux 4.2
The latest subsystem update worth commenting on for the Linux 4.2 merge window are the crypto(graphy) updates with this new kernel version.
Yet another system has been added to our continuously growing basement server farm that tracks the performance of various upstream open-source projects on a daily basis. Meet system number 58!
With the new Linux kernel mailing list thread about the prospects of merging KDBUS into the mainline Linux kernel, Linus Torvalds has provided his thoughts on the matter for this controversial feature backed by systemd developers for trying to provide a high-performance, kernel-based IPC solution.
The latest pull request to be submitted for Linux 4.2 is providing a new processor architecture port.
With Linux 4.1 having been released this week and being mid-way through 2015, here's some Git development statistics for the newest kernel code.
Open-source developers for a while have been working on ACPI 6 support for Linux with 64-bit ARM support, ACPI 6 NV-DIMM support, and other functionality. With the Linux 4.2 kernel that's now in-development, more ACPI 6 code will be landing.
Alongside his many other pull requests, Ingo Molnar sent in the scheduler changes on Monday for the Linux 4.2 kernel.
Trailing last night's release of the Linux 4.1 kernel is the release of the GNU Linux-Libre 4.1 kernel via the Free Software Foundation of Latin America. This re-base against the upstream Linux 4.1 kernel takes care of "de-blobbing" more non-free areas of the open-source Linux kernel.
Jiri Kosina of SUSE has sent in the HID driver updates for the Linux 4.2 kernel and with it comes new device support.
The "x86 core" pull request for Linux 4.2 is quite hearty.
The x86 EFI changes for Linux 4.2 were mailed in this morning and indeed they offer the EFI System Resource Table support as necessary for supporting UEFI 2.5+ system firmware updates.
Waiman Long of HP has been spearheading qspinlocks now for the past several months and with Linux 4.2 the queue spinlocks support will be merged.
The Linux 4.1 kernel was released over the night by Linus Torvalds.
If all goes well, the Linux 4.1 kernel will be released before the day is over. Linux 4.1 is yet another exciting update and here's a look at some of the most prominent work found in this new kernel version.
More of the Linux kernel's complicated and poorly maintained x86 Assembly code continues to be rewritten in modern and clean C.
The DRM subsystem pull for the Linux 4.2 kernel is nothing short of huge. There's some more work to talk about today.
The Linux 4.2 has many new features coming and now there's another one: atomic mode-setting support for the OMAP DRM driver that also improves the overall open-source driver quality.
Linus Torvalds just released the Linux 4.1-rc8 kernel as the final planned test version before the official Linux 4.1 release.
With Linux 4.1 likely being released in the next week, for Phoronix-reading Linux enthusiasts it's time to start thinking about Linux 4.2. Here's a look at some of the new features coming for this next kernel cycle.
For years the BFQ I/O scheduler has been trying to get in the mainline kernel and it looks like they have an action plan for getting accepted upstream.
Another Sunday, another Linux kernel update. Linus Torvalds just tagged the Linux 4.1-rc7 kernel release.
The Linux 4.2 kernel will make the CFQ I/O scheduler default to its IOPS mode when on solid-state drives, which should boost performance.
The Linux 4.2 kernel will bring to mainline two prominent new Direct Rendering Manager drivers.
The upcoming Linux 4.1 kernel release will be supported for the long-haul by the Linux Foundation's LTSI project.
