A 10x Workaround & Less Network Egress Downtime Change Submitted For Linux 6.17
29 July 2025 - Linux 6.17 Locking

The kernel locking changes submitted today for Linux 6.17 contain a temporary change worth discussion for yielding a 10x speed-up of a particular function call and as part of that yielding less network egress downtime until a better solution is developed.

Huge Speedups For CRC32C With Modern AVX-512 CPUs Merged To Linux 6.17
29 July 2025 - CRC32C Optimizations

The CRC32C cyclic redundancy check code path within the Linux kernel for error detection is much, much faster with the in-development Linux 6.17 kernel when running on modern Intel and AMD AVX-512 processors.

Linux 6.17 Staging Continues Cleaning The Realtek RTL8723BS Driver
29 July 2025 - Linux 6.17 Staging

The staging area of the Linux kernel, where preliminary code initially appears to mature until being promoted out, continues seeing a lot of code churn. With Linux 6.17 the staging updates were submitted and now merged with one driver in particular standing out.

Longtime Linux Kernel Engineer With 14 Years At Intel Is Now At Meta
29 July 2025 - Meta

Facebook's Meta already employs an all-star team of Linux kernel engineers and it doesn't appear that they are over in recruiting top-tier Linux kernel talent. One of Intel's senior Linux software engineers is now the latest high profile kernel developer onboard at Meta.

Linux 6.17 Improves NUMA Locality For SMP Call Rather Than Deferring To Random CPU Core
29 July 2025 - smp_call_function_any

After all of these years of Linux dominating the high performance computing (HPC) space and other industries, one might think (most) all the interesting performance nuggets have been uncovered and well thought out and robust fallbacks in place across all important code paths. As we showcase almost each cycle, interesting new performance bits to be uncovered within the Linux kernel. For Linux 6.17 thanks to a NVIDIA engineer is applying a better fallback for NUMA locality rather than simply picking a random CPU core.

Linux 6.17 Now Makes Multi-Core/SMP Support Unconditional
30 July 2025 - Always SMP

Earlier this year Linux kernel patches were posted for making SMP support unconditional so the kernel is always built for multi-core capabilities. With uniprocessor core environments being extremely rare especially for those that would be using an up-to-date, upstream Linux kernel, dropping non-SMP support would allow simplifying code paths within the kernel. Well, for Linux 6.17 it's finally happening.

Linux's Lockdown LSM Back To Being Maintained For Restricted Computing
31 July 2025 - Linux Lockdown

Upstreamed to the Linux kernel back in 2019 was the Lockdown security module for opt-in hardware/kernel security restrictions. It was a difficult and contentious process getting to the Linux kernel but then was left without any formal maintainer shortly after being mainlined. Now for helping to renew this Linux security module, two developers have stepped up to takeover maintainership of Lockdown.

Intel QuickAssist Hit By Second Demotion In Linux 6.17 Due To Lack Of Kernel Benefit
3 August 2025 - Intel QuickAssist

A few days ago the Intel QuickAssist "QAT" accelerators were demoted by FSCRYPT in the Linux 6.17 development code due to being slow and bug prone with AVX-512 showing to be much faster than leveraging the QAT accelerators in this file encryption framework. With the Linux 6.17 crypto subsystem is a second separate demotion to Intel's QAT support for kernel use.

Linux 6.17 Making Kdump Crash Kernel More Reliable, Less Wasted Memory
4 August 2025 - Linux 6.17 Kdump

In addition to the many MM changes merged this weekend for Linux 6.17, Andrew Morton on Sunday also sent out his "non-MM" pull request for this new kernel. Notable there is improving the Kdump code to allow for crash kernel reservation made from the contiguous memory allocator to help yield less wasted RAM and greater reliability.

杂谈:
我经常把Telegram的收藏夹当成安全、高效、可同步的便签功能使用,但使用Telegram这么多年我曾经遇到过一次收藏夹消息随机丢失的问题,并且只发生在Android客户端上。当时的解决方法有点笨:在PC客户端上把没丢失的消息转发给其他用户,再转发回来。
结果在昨天收藏夹消息随机丢失的问题又发生了一次,这次我随便摸索了一下,找到了解决方法:
在系统设置中查看Telegram的应用信息,点击“清除数据”,然后点击“管理空间”,在新界面点开右上角的菜单,然后点击“清除本地数据库”。
