Linux 3.13 Kernel To Bring Major Feature Improvements 190

Posted by timothy from the this-is-only-the-free-version dept.
An anonymous reader writes "There's many improvements due in the Linux 3.13 kernel that just entered development. On the matter of new hardware support, there's open-source driver support for Intel Broadwell and AMD Radeon R9 290 'Hawaii' graphics. NFTables will eventually replace IPTables; the multi-queue block layer is supposed to make disk access much faster on Linux; HDMI audio has improved; Stereo/3D HDMI support is found for Intel hardware; file-system improvements are on the way, along with support for limiting the power consumption of individual PC components."

      Mehhh. I used to update my kernel as quickly as possible when they promised major improvements. It always turns out that a "major improvement" is actually an "incremental improvement". I lost the excitement over kernel upgrades some time ago. I still upgrade from time to time, but my attention is more focused on security than any supposed "improvements". I don't want to be the odd guy who is caught with some vulnerability that was fixed eight versions ago. Two versions, maybe - but eight? Nope, no way! That would be just to embarrassing.

          The Ubuntu LTS+HWE model is interesting; you can basically install the kernel from Ubuntu 12.10, 13.04, or 13.10 on your 12.04 LTS system.

        • As you build your own kernels instead of using distro-provided binaries, what's the reason to not skip a release you don't like? 3.11 breaks VirtualBox, it works fine both with 3.10 and 3.12-rc (and now with 3.12.0). A regression that lasts is bad, one that has been fixed in a later version means just "please upgrade".

          The multi-queue block layer [phoronix.com] which is merged in kernel 3.13 gives a 3.5x to 10x increase in IOPS. This change is mostly targeted for SSDs, but gives similar improvements on HDs as well. However, it's not clear whether this improvement is relative to 3.11 or not.

    • That is some of the most absurd thinking I have ever heard. The fact that things improve and get better does not mean that things are bad as they are now. These new features are additions to an already great product. Linux as it is is already better than Windows, so the new features will make it better still. Notice as well, that each Windows realese always comes with a long list of improvements from the last version. The whole purpose of having new versions is to improve things and add new capability.
