This bills itself as \u201can advanced new filesystem for Linux, with an emphasis on reliability and robustness and [a] complete set of features\u201d.<\/p>\n<\/p>\n<p><p>It\u2019s said to offer several compelling lures versus existing dominant file systems like ext4, which is used by Ubuntu, including checksumming and multi-device functionality within a filesystem, is said to be \u2018safer to use\u2019 than btrfs, and faster than zfs \u2014 sounds like one to watch!<\/p>\n<\/p>\n<p><h3>Valve helps levels up btrfs<\/h3>\n<p>Of the 3 new Btrfs features included in Linux 6.7 the addition of FSID (temporary file-system ID) will garner most interest. <a href=\"https:\/\/lore.kernel.org\/linux-btrfs\/20230504170708.787361-1-gpiccoli@igalia.com\/\" target=\"_blank\" rel=\"nofollow noopener\">Igalia\u2019s Guilherme Piccol worked on this feature<\/a> at the request of Valve, who are looking to leverage it in their Linux-based Steam OS on the Steam Deck. <\/p>\n<p>To quote Guilherme, FSID allows <em>\u201c\u2026systems with A\/B partitioning scheme (like the Steam Deck console or various mobile devices) to be able to hold the same filesystem image in both partitions\u201d.<\/em><\/p>\n<h3>Graphics gains galore<\/h3>\n<\/p>\n<p><p>NVIDIA GSP firmware is also a notable addition, <a href=\"https:\/\/www.phoronix.com\/news\/Linux-6.7-Features-Today\" target=\"_blank\" rel=\"nofollow noopener\">as Phoronix says<\/a> it brings better power management and performance for GeForce RTX 20 and RTX 30 series hardware (when running with proprietary firmware blobs), as well as RTX 40 acceleration in Nouveau setups \u2014 nice!<\/p>\n<p>Intel Meteor Lake graphics support in Linux 6.7 is now considered stable, which is great news. But, as ever, progress never stops! To this end, a glut of graphics bringup for Intel Xe 2 Lunar Lake integrated graphics ships in this release.<\/p>\n<h3>Intel Itanium IA-64 support dropped (for now)<\/h3>\n<p>I can\u2019t imagine it\u2019s going to affect any folks who read this site, but the Linux 6.7 kernel drops support for the Intel Itanium IA-64 architecture \u2014 completely! All code has been removed from the kernel tree. Naturally, some folks aren\u2019t happy about this. Linus is sanguine, adding: <\/p>\n<\/p>\n<p><p><em>\u201cI\u2019d be willing to resurrect itanium support, even though I personally despise the architecture with a passion for being fundamentally based on faulty design premises, and an implementation based on politics rather than good technical design \u2026 But only if it turns out to actually have some long-term active interest\u2026\u201d<\/em><\/p>\n<\/p>\n<p><p>For more details on everything included in this Linux kernel release I highly recommend sifting through through the comprehensive LWN merge window summaries (<a href=\"https:\/\/lwn.net\/Articles\/949294\/\" target=\"_blank\" rel=\"nofollow noopener\">part 1<\/a>, <a href=\"https:\/\/lwn.net\/Articles\/949957\/\" target=\"_blank\" rel=\"nofollow noopener\">part 2<\/a>).<\/p>\n<\/p>\n<p><h2>Getting Linux 6.7<\/h2>\n<\/p>\n<p><p>New Linux kernels aren\u2019t automatically packaged up and released to existing versions of Ubuntu. <\/p>\n<\/p>\n<p><p>When it comes to interim releases, the kernel series that is included at the time of release is the one it adheres to. Although Ubuntu Long-Term Service (LTS) releases receive updated versions of Linux kernels, these are often backported. And since currently, not a single Ubuntu release utilizes the 6.7 version, there&#8217;s nothing available for backporting.<\/p>\n<\/p>\n<p><p>It is indeed possible to install a new primary Linux kernel in Ubuntu and its derivatives, such as Linux Mint. This can be done through <a href=\"https:\/\/wiki.ubuntu.com\/Kernel\/MainlineBuilds\" rel=\"nofollow noopener\" target=\"_blank\">mainline kernel builds<\/a>, which are created by Ubuntu developers (Note: at the time of writing, the v6.7 version isn&#8217;t available but expected to appear soon).<\/p>\n<\/p>\n<p><p>However, it should be noted that Ubuntu&#8217;s primary kernel builds are not intended for everyday users like us. They come without support, may not have certain kernel-enabled patches normally present in regular Ubuntu Linux kernel releases, may have bugs or idiosyncrasies, etc. Therefore, if you choose to use them, proceed with caution.<\/p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new year, and an all-new Linux kernel to help power it along!
