Linux Kernel 4.9 was finally released last night as ‘the biggest release’ said in the announcement. Linus Torvalds wrote on lkml.org:

So Linux 4.9 is out, and the merge window for 4.10 is thus open.

With the extra week for 4.9, the timing for the merge window is obviously a bit awkward, and it technically closes in two weeks on Christmas Day. But that is a pure technicality, because I will certainly stop pulling on the 23rd at the latest, and if I get roped into xmas food prep, even that date might be questionable.

I could extend the merge window rather than cut it short, but I’m not going to. I suspect we all want a nice calm winter break, so if your stuff isn’t ready to be merged early, the solution is to just not merge it yet at all, and wait for 4.11. Just so you all know (I already bcc’d the main merge window suspects in a separate mailing last week, I’m just repeating myself here to avoid anybody being confused about timing).

Anyway, back to 4.9 itself.

I’m pretty sure this is the biggest release we’ve ever had, at least in number of commits. If you look at the number of lines changed, we’ve had bigger releases in the past, but they have tended to be due to specific issues (v4.2 got a lot of lines from the AMD GPU register definition files, for example, and we’ve had big re-organizations that caused a lot of lines in the past: v3.2 was big due to staging, v3.7
had the automated uapi header file disintegration, etc). In contrast, 4.9 is just big.

Admittedly a chunk of that is the new greybus staging support, but that really isn’t the bulk of it – it’s just another small detail in the overall “yes, v4.9 is big” picture.

Other than just the size, 4.9 looks fairly normal. A bit over two thirds drivers (staging, GPU and networking are the bulk of it, but it’s all over), with the rest looking fairly normal too: arch updates, documentation, generic networking, filesystems..

The shortlog (16k+ commits, with another 1100 merge commits to round things out) is obviously much too big to put here, and wouldn’t be legible anyway. So as is my wont, I’m appending just the log of my merges.

New Features in Linux Kernel 4.9:

  • Virtual Display Support and improved GPU reset for AMDGPU.
  • Various fixes and improvements to Intel DRM.
  • Memory protection keys (MPK) support.
  • Support for vmapped kernel stacks.
  • 29 more ARM machines support, including Raspberry Pi Zero, LG Nexus 5, etc.
  • Various file-system improvements and more.

How to Install Linux Kernel 4.9:

The Ubuntu kernel team has build the new kernel release, and the binaries are available for download at the link below:

Depends on your OS type, grab and install the packages below one by one:

  • linux-image-4.9.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio), amd64 for 64bit system, i386 for 32bit system, or armhf, arm64, etc for other OS types.

Kxstitch, an open-source cross stitch pattern and chart creation software for KDE, has now reached the 2.0 release with KF5 port, a number of improvements and lots of new language translations.

Patterns can be created from scratch on a user defined size of grid, which can be enlarged or reduced in size as your pattern progresses. Alternatively you can import images from many graphics formats which will allow you to reduce the number of colours and to restrict the conversion to full stitches or optionally use fractional stitches.

You may also use an image as a background. These imported images can then be modified using the supplied tools to produce your final design.

Kxstitch Features:

  • Creation of new patterns
  • Editing of existing patterns – KXStitch is also capable of reading PC Stitch 5 files.
  • Use of various floss pallets, DMC, Anchor, Madeira, JP Coates
  • Creation of custom palettes and colours.

  • Free use of backstitching
  • Importing of various picture formats
  • Printing of patterns and floss keys
