      Bcachefs Aims For "Soft Frozen" On-Disk Format With Linux 6.15 Along With New Features

      news.movim.eu / Phoronix • 24 March, 2025

    Last month Bcachefs lead developer Kent Overstreet talked of Bcachefs getting to the point of freezing its on-disk format with future on-disk format updates slated to be optional. With today's Bcachefs pull request for Linux 6.15, it's now being treated as "soft frozen" and also landing other new features for this copy-on-write file-system. Among the new features is case insensitive file/folder support contributed by Valve...

      Linux 6.14 Released With Working NTSYNC Driver, AMD Ryzen AI Accelerator Support

      news.movim.eu / Phoronix • 24 March, 2025

    There was a hiccup yesterday with no Linux 6.14 release or 6.14-rc8 otherwise... Linus Torvalds has a very good track record of sticking to his Sunday release regiment. Yet yesterday was quiet. Today though Linus Torvalds released the Linux 6.14 kernel as the newest stable version. Linux 6.14 is what's set to go on and power Ubuntu 25.04, Fedora 42, and other spring 2025 Linux distribution releases...

      Intel's AVX10.2 Patches Merged For GCC 15 To Drop 256-bit Rounding & AVX10.2-256 Options

      news.movim.eu / Phoronix • 24 March, 2025

    What a week. Last week Intel published a new AVX10 whitepaper where they dropped the optional 512-bit support of AVX10.2 and confirmed future P and E cores will have AVX10.2-512 support unconditionally. A very welcome change by Intel albeit late in rushing to get patches out to change that behavior ahead of the GCC 15 stable compiler release as well as working similar changes into the LLVM Clang compiler. As of today those GNU Compiler Collection patches have been merged to prepare for AVX10.2 always having 512-bit support available...
