Weighted Interleave Auto-Tuning Being Worked On For Linux
20 December 2024 - Weightened Interleave Auto-Tuning

Joshua Hahn has posted the latest "request for comments" draft working on weightedd interleave auto-tuning for the linux kernel in order to better enhance the performance characteristics of primarily Linux servers with multiple memory nodes.

Liquorix vs. Linux 6.12 Upstream Kernel Performance Across Many Workloads
20 December 2024 - Linux 6.12 Liquorix

A Phoronix Premium subscriber a while back requested some fresh benchmarks of how the Liquorix downstream of the Linux kernel is comparing against the latest upstream kernel... Here are some benchmarks looking at the Liquorix flavor of the Linux kernel compared to upstream Linux 6.12.

Linux 6.14 Looks To Land Rust PCI / Platform Device Driver Support
23 December 2024 - Linux 6.14 Rust Device Drivers

The patch series in the works for a while to provide the necessary kernel abstractions for the Rust programming language to actually implement real device drivers looks like it will finally premiere in the Linux 6.14 kernel cycle.

Redmi K60/Poco F5 Pro(mondrian)昨晚发包了官方版HyperOS 2.0,作为首个得到官方HyperOS 2.0更新的小米SM8475机型,我们marble用户也可以从中提取出一些有价值的信息。

首先是内核,更新到了5.10.209
然后是内核模块,从vermagic来看,还是5.10.160,并没有像MIUI14升级HyperOS1一样得到更新,并且绝大多数内核模块和HyperOS1不能说一模一样只能说毫无区别。
再然后是dtb和dtbo,也没啥变化。

可以预见的是,marble官方版的HyperOS 2.0在内核层的更新内容也会和mondrian差不多,而且Melt Kernel基本上只需要做少量改动即可兼容。

最后,只是一些个人猜测:对于正在给marble搞HyperOS 2.0移植并且发现AOD有bug的开发者,把msm_drm.ko换成mondrian HyperOS 2.0里的试试?
谈一谈最近在Telegram圈子里比较火的susfsKernelSU-Next

先说说susfs,该项目已在Readme中明确表示代码是实验性的,并且代码变更极其频繁,作为一名第三方内核开发者,将如此不稳定的功能添加到自己维护的内核中是极其不负责任的行为。提到Readme,我就实在很想吐槽了,这个Readme我来来回回看了许多遍,愣是没看明白这是个什么玩意:它有什么功能?如何使用?应该在什么场景下使用?我一概不知,一大半的篇幅都是在说如何安装、编译,作为一名想要了解你的项目的人,我首先需要关注的是这个吗?最近也有很多人请求我为Melt Kernel添加susfs支持,但他们只说这是个好东西,再详细点就是说这玩意能进一步隐藏KernelSU,但从来没有人再进一步给我详细说明这玩意的作用,你自己都搞不明白这玩意有啥用怎么用,那你让我添加这玩意干嘛?我只想说我对susfs已经没有任何好感度了。

综上所述,在susfs摆脱实验性代码的标签之前、在susfs被广泛且有效使用之前,我绝对不会考虑将其添加到Melt Kernel。

然后再说说KernelSU-Next,作为一个KernelSU的非官方分支版本,同样是支持LKM安装方式的。因此对于想要尝鲜KernelSU-Next的Melt Kernel用户,请自行通过LKM方式安装,并且在安装Melt Kernel的过程中,不要选择安装KernelSU。

还有一点需要注意,如果你选择在使用Melt Kernel的同时安装并使用KernelSU-Next,我将不会为你提供任何技术支持。
Hash-Based Integrity Checking Proposed For Linux To Help With Reproducible Builds
26 December 2024 - Reproducible Kernel Builds

An interesting request for comments (RFC) patch series was posted on Christmas for introducing hash-based integrity checking to help with the reproducible builds initiative around the Linux kernel.

Linux's Preempt Lazy Support Coming To POWER CPUs
27 December 2024 - Preempt Lazy For PowerPC

Linux 6.13 is introducing a new Lazy Preemption mode with the "PREEMPT_LAZY" option. The lazy preemption mode is similar to full preemption but is less eager to preempt normal (SCHED_NORMAL) tasks. The goal is on reducing lock holder preemption and obtaining some of the performance gains found under the voluntary preemption mode. For Linux 6.13 the lazy preemption mode was exposed for x86/x86_64, RISC-V, and later added for LoongArch. Likely with the upcoming Linux 6.14, lazy preempt should work on POWER platforms.
