The merge model has opened for what will go Linux type 6.7, and beneath we've compiled immoderate things that are apt to beryllium included successful nan caller release.
Now that really not very devilish kernel 6.6 is out, we tin commencement to look guardant to what will dress up nan adjacent release, which will astir apt beryllium vanished immoderate clip early successful 2024. The work-in-progress character for things that might spell into nan kernel is collectively known arsenic linux-next, and things that spell into it may – but whitethorn not – make it into nan adjacent version. So what changes are happening already successful linux-next shape a decent denotation of what lies ahead.
In a task of this ever-changing nature, driven by thousands of contributors, arsenic caller hardware support is added, support for aged hardware is gradually phased out. Sometimes, that intends types of hardware alternatively than circumstantial devices, which tin consequence successful tens of thousands of lines of codification being expunged arsenic dozens of drivers collectively look nan chop each astatine once.
Now that Intel's Itanium family of chips is fading into history, support for this unloved architecture successful Linux is being dropped. The codification was orphaned successful early 2021, and though removal was vetoed successful February, a patch to region nan codification went done recently. In this context, IA64 denotes Itanic, not 64-bit x86, which is referred to arsenic x86-64, AMD64, aliases X64 by different groups.
Another projected change, presently astatine nan "request for comments" stage, would region drivers for a batch of early non-busmastering web cards, notably a twelve geriatric wireless cards. A small newer and a batch quicker, nan driver for Qlogic's 10GbE QLGE paper is going, excessively – but past Qlogic itself is gone, scoffed by Cavium who were successful move munched by Marvell.

As we have described before, nan developers down nan next-gen Bcachefs are trying once again, but this clip its chances of inclusion look better: it made it into linux-next past month.
We fishy that rather a fewer distros would for illustration to driblet support for 32-bit x86 binaries, but a batch of group still usage them. Ubuntu tried successful 2019 but an outcry forced it to backtrack, truthful it conscionable dropped support for 32-bit hardware. Users of 64-bit Ubuntu tin still tally 32-bit binaries today, and immoderate of america do. This isn't conscionable for gamers; for instance, The Reg FOSS table still has WordPerfect 8 for Linux installed – released for free agelong earlier 64-bit PCs were moreover a daydream – and occasionally moreover uses it.
Part of nan problem is that correct now, 32-bit x86 support connected 64-bit Linux comes successful 2 abstracted parts: a group of 32-bit libraries that you tin easy install, and wrong nan kernel itself, nan 32-bit interfaces that those libraries need. Currently, if nan kernel is compiled pinch those turned off, x86-32 codification can't beryllium executed. To make 32-bit support optional would beryllium tricky; for example, vendors would person to proviso 2 sets of kernels, 1 with 32-bit support and different without. So almost everyone conscionable leaves it on.
A caller patch will move this into an action that nan personification tin take astatine footwear time. That intends that vendors could vessel their distros pinch it turned off, but if nan personification installs 32-bit libraries, 32-bit binary support tin beryllium enabled; each that will beryllium needed afterward is simply a reboot to tally codification built for older 386, 486, aliases Pentium chips.
There are a raft of different changes pending, including various improved Intel instrumentality drivers, immoderate tweaks for handling AMD processors, and immoderate improved Btrfs filesystem handling thanks to Valve's Steam Deck. For a much complete rundown, Linux benchmarking boffin Phoronix has a bully overview. ®
