Linux 7.2-rc7 Restoring Btrfs Fixup Worker Infrastructure To Address Silent Data Loss

6 août 2026 à 21:09
Back during the Linux 7.2 merge window the Btrfs file-system dropped its COW fixup mechanism, which was used to detect dirty pages without an ordered extent. This code was removed as it was believed the kernel's memory management layer had solved the underlying conditions but in reality it ended up leading to silent data loss. That Btrfs fixup worker infrastructure is now restored in time for Linux 7.2-rc7 this weekend and the stable v7.2 kernel later this month...

The Performance Benefits To Upgrading Mesa With Intel Arc B390 On Ubuntu Linux

6 août 2026 à 14:44
If you are an early customer of the Framework Laptop 13 Pro or other Intel Core Ultra Series 3 Panther Lake laptop and using Ubuntu 26.04 LTS, there can be real benefit from upgrading your Mesa stack for the newer Iris Gallium3D and ANV Vulkan drivers. In this article are some benchmarks of the Framework Laptop 13 Pro with Core Ultra X9 388H with Arc B390 Xe3 integrated graphics for looking at the performance impact of using Mesa Git on Ubuntu Linux.

Linux Accidentally Left Legacy I/O & Memory Handlers Open In Kernel Lockdown Mode

6 août 2026 à 13:50
For nearly the past decade has been the kernel lockdown mode for tightening up kernel access from user-space such as when UEFI Secure Boot is enabled. The kernel lockdown mode restricts PCI BAR access, no writing to /dev/mem, and other restrictions so user-space can't modify the running kernel or access sensitive kernel memory. An oversight has allowed legacy I/O and memory interfaces via sysfs to remain open in lockdown mode, but a fix is on the way...

Page Alloc Hogger Lets You Better Stress Memory Behavior On Linux For Testing/Debugging

6 août 2026 à 10:28
A new kernel feature proposed by a Google engineer is Page Alloc Hogger to allow for fine control over where memory pages are allocated in order to more easily reproduce low-memory conditions, make it simpler to exert memory pressure, and enable other stressful memory conditions for testing/debugging how Linux copes...

AMD GFX1171 Support Merged For Mesa 26.3

6 août 2026 à 10:19
Earlier this year we began seeing patches for AMD GFX1170 graphics IP labeled as "RDNA 4m" and that was then completed with also adding GFX1171 and GFX1172 as additional targets for the AMDGPU LLVM compiler back-end and AMDGPU kernel driver. Merged today for Mesa 26.3 is now adding the GFX1171 target to Mesa 26.3 for the RADV and RadeonSI drivers...

Additional Old Linux Drivers Face Removal Due To Noise From AI/LLM Coding Agents

5 août 2026 à 10:38
There continues to be a lot of cleaning up of the kernel source tree to deal with noise generated by AI / LLM coding agents sending in reports and patches for old drivers that are likely not actively used by anyone on modern upstream kernel builds. Rather than continuing to carry these old drivers around with the uptick in AI/LLM-generated noise, kernel maintainers are finding it better to just retire the old drivers...
