One of the exciting additions to the Linux 7.1 kernel is the introduction of the new NTFS file-system kernel driver. While in good shape already and proving advantageous over other NTFS open-source driver options, one of the initial limitations on it is around Windows native symb…
Linux cryptography subsystem expert Eric Biggers Eric Biggers of Google worked on some pretty nice Intel/AMD x86_64 optimizations over the years. Especially around AVX-512 optimizations within the Linux kernel's crypto code has been one of his many nice improvements to the kernel…
Being submitted on the kernel side with the upcoming Linux 7.2 kernel is initial support for the GFX 11.5.6 graphics IP block along with several other newer IP blocks such as SDMA 6.4, NBIO 7.11.5, IH 6.4, HDP 6.4, MMHUB 3.4.2, SMU 15.0.5, ATHUB 3.4.2, and VPE 2.2. Now in user-sp…
The Linux kernel has long tried to use huge pages as a way to improve performance, sometimes with more success than others. The size of huge pages has traditionally been imposed by the hardware, which typically only offers a couple of relatively large options. In more recent time…

Installing a replacement drive on my first TrueNAS build. The ERC is set to 0.1s, which seems odd. I can’t change it’s value however. With smartctl -l scterc,70,70 /dev/sdd it just keeps reverting to 0.1 seconds right away. (This is happening to all 6 of my 24TB WD HC580 refurbis…
An important one-liner is set to come for Linux 7.2 to enable ESWIN SoC support by default for RISC-V kernel builds. This change will allow default RISC-V kernel builds in turn to boot on the likes of SiFive's HiFive Premier P550 developer board...

Hey guys, i just got a kernel patch that speeds up USB dongles running the mt76 driver acked for the next PR period. The USB driver used to hand RX frames up without a NAPI, so it never got GRO and ran single-threaded which capped its speed ~380mbps while the PCIe path flew. I en…
The linux-firmware.git repository that serves as the de facto home of all the binary blobs used by the mainline Linux kernel open-source drivers has now introduced AGENTS.md documentation and other preparations for embracing AI coding agents...
While not as exciting as features like HDMI 2.1 FRL and Display Stream Compression itself, as part of AMD's efforts to provide a fully open-source HDMI 2.1 driver implementation for AMDGPU, new code is being prepped for their kernel driver to support the HDMI compliance testing e…
Among the Kernel-based Virtual Machine (KVM) work being queued ahead of the upcoming Linux 7.2 merge window are preparations for supporting Advanced Performance Extensions within KVM virtual machines...
After years of distro-hopping I moved my R9 5900HX + RTX 3080 laptop from Windows 11 to Fedora 44, and two problems I had just accepted as normal disappeared. Heat: on Windows it sat at 90C+ and throttled constantly. Fedora's newer kernel and out-of-the-box power management dropp…
An anonymous reader quotes a report from Ars Technica: Researchers have analyzed a high-severity vulnerability in Linux that's able to escalate untrusted users to root by exploiting a bug you don't often see: a single errant character inside the kernel. The vulnerability, tracked…

Hi I have decided to tag a release of ReterminateVT, which used to be called fakekmscon, until I renamed it when kmscon became active again. fakekmscon has been around since 2020, with kmscon actually being brought back, I have renamed it to ReterminateVT. I don't know the best m…
Hello there folks! I am new on here and I would like y'all's opinion on something. I am currently using Windows 11 IoT Enterprise LTSC 2024 as my daily drive OS and I am quite okay with it. However I keep seeing videos about Linux, specifically heard great things about Nobara Lin…
Following the official Fedora 44 images released one month ago, Fedora 44 RISC-V images were published today for those wanting to run this newest Fedora Linux on RISC-V hardware...
Security researchers have published a detailed, working exploit for a Linux kernel use-after-free that lets an unprivileged local user escalate to root and break out of a container. The flaw, CVE-2026-23111, sits in the kernel's nf_tables packet-filtering code and was patched ups…
Last week I ran benchmarks of CachyOS with the BORE scheduler using its "linux-cachyos-bore" kernel option. The results didn't end up being as enticing as anticipated but the developer behind the BORE scheduler commented in the forums that he recently received reports from users …
For the last few days I've been working on what I call ChainBoot and wanted to share it a bit. Essencially it's just LinuxBoot (remember that?) but instead of being part of the firmware it gets loaded by your UEFI or BIOS. I've run into the situation where I want to boot from a s…
Recent testing of the Intel Arc B580 Battlemage desktop graphics card has shown that the upcoming Linux 7.1 kernel release is delivering superior graphics performance over the current stable Linux 7.0 kernel.
Apparently, Silicon Graphics (SGI) made another filesystem EFS (Extent File System) before their more popular XFS (eXtent (?) File System). The Linux kernel has a read-only implementation of EFS. It looks to have been added around kernel 2.2 (before Linux used git). IRIX (SGI's o…

An interesting quandary has arose on the Linux kernel mailing list over maintainership of old, unmaintained code within the Linux kernel. Someone has stepped up to maintain an old, very rare file-system driver but admittedly doesn't even use it and just submitted basic fixes. Or …
In addition to the SpacemiT K1 and K3 RISC-V SoC Device Tree updates sent out last week, the RISC-V T-HEAD Device Tree "DT" changes were also sent out last week ahead of the upcoming Linux 7.2 kernel merge window...
The 7.1-rc7 kernel prepatch is out for testing. Linus said: "Anyway, as things look now this is the last rc. Something can obviously always come up and force us to change that, but please give rc7 a whirl and keep testing for one more week."
Last week Linux 7.1-rc6 was larger than Linus Torvalds wished for and for Linux 7.1-rc7 it has come in still heavier than typically seen this late in the cycle, but is shrinking and making Linus comfortable in hopefully releasing Linux 7.1 stable next Sunday...
I was dig-ing through some hosts to check IPv6 support when I noticed kernel.org's AAAA record: 2600:3c04:e001:324:0:1991:8:25 That suffix (::1991:8:25), is August 25, 1991, the day Linus Torvalds posted his famous announcement to comp.os.minix. Couldn't find any posts about this…
The ZFS filesystem was originally developed by Sun in the early 2000s for their Solaris operating system. However, the ZFS that most people are familiar with is openZFS (running on Linux). Originally proprietary, ZFS became open-source under the CDDL license in 2005 after Sun ope…
Ahead of the Linux 7.1-rc7 test kernel release due out later today, a pull request has been submitted of some "x86 fixes" for this kernel release. Most notable with this pull request is acknowledging some additional AMD Zen 6 CPU models...
Broadcom V3D 3.3 and V3D 4.1 graphics IP is set to be deprecated and removed from the V3D kernel graphics/display driver after the Mesa driver support was removed two years ago already. The situation in both cases amount to lack of hardware by developers for testing and with that…
So a little while ago, i learned that Microsoft made a linux distro called Azure Linux, turns out it was just the continuation of another project they used called CBL Mariner, i found that pretty cool and tried it in a VM, obviously as a surprise to nobody, it's a server distro n…
It's unfortunately another busy week in the Linux 7.1 kernel space with not everything slowing down so well, late in the cycle and leading to the upcoming 7.1 stable release. This week's DRM pull request of kernel graphics/accelerator drivers is again heavy on fixes and also ends…
Multiple software supply chain attacks have hit the npm ecosystem, with threat actors using both malicious and poisoned versions of over 50 legitimate packages to distribute a Rust-based information stealer and a self-spreading worm, respectively. According to JFrog, the informat…

Danilo Krummrich sent out the main set of DRM Rust subsystem changes on Thursday that are targeting the Linux 7.2 kernel. NVIDIA's open-source Nova driver continues seeing a bulk of the DRM Rust work as this modern successor to Nouveau continues taking shape...
In addition to AMDGPU finally seeing HDMI 2.1 FRL support in Linux 7.2, another change worth noting in this week's AMDGPU pull request is the continued work on enhancing the AMDGPU/AMDKFD kernel driver support for non-4K page size kernel builds. In particular this helps out with …
Earlier this week I ran benchmarks of different CachyOS Linux kernel flavors that proved interesting from the performance overhead of their hardened kernel build to various other interesting performancr takeaways. One kernel flavor I hadn't tested though was their build with the …
The Software Engineering Radio podcast has put up an interview with graphics maintainer Dave Airlie. Much of what is in there will not be news to LWN readers, but it is an interesting overview of the life of a large-subsystem maintainer. I was talking to a few of the Rust people,…
A new npm supply-chain attack has infected 36 packages with Rust-based infostealer malware called IronWorm. According to BleepingComputer, the malware "targets 86 environment variables (key-value pairs) and 20 credential files that may contain OpenAI, AWS, Anthropic, and npm cred…
With this week's launch day review of the AMD Radeon RX 9070 GRE, Ubuntu 26.04 with its Linux 7.0 and Mesa 26.0 default driver stack was used for testing. That choice was made since the Ubuntu 26.04 release is still fresh, the RDNA4-based RX 9070 GRE was working without issue the…
The upcoming Linux 7.2 mainline kernel is expected to be able to boot on Apple M3 devices including the M3-powered iMac and MacBook products. But before getting too excited it's still a long ways to go before it will actually be useful for any Apple M3 daily usage under Linux wit…
