Linux 5.16's New Cluster Scheduling Is Causing Regression, Further Hurting Alder Lake
Linux 5.16-rc1 is coming out later today and already I'm seeing some fallout in the new kernel's performance... In particular, bad news for Alder Lake that is already seeing the Linux performance trailing Windows 11 seemingly due to the lack of Thread Director integration right now in the kernel and any other missing optimizations around Intel's hybrid architecture. A new feature of Linux 5.16 is unfortunately having unintended regressions for Alder Lake with at least the flagship Core i9 12900K. Here are the results from the latest kernel bisecting that uncovered this latest upstream slowdown.
Tensor LLVM Extensions Proposed For Targeting AI Accelerators, Emerging Hardware
Intel, Amazon AWS, IBM, Qualcomm, and UIUC researchers have been collaborating over a proposed "Tensor LLVM Extensions" (TLX) to make this open-source compiler infrastructure more suitable for targeting AI accelerators and other emerging classes of hardware...
"MGLRU" Code Updated For More Performant Linux Page Reclamation
While not coming as part of the new 5.16 cycle, one of the exciting patch series to come about this year has been Google's work on the Multigenerational LRU (MGLRU) Framework for improving performance around the kernel's page reclaim handling...
QEMU 6.2 On The Way With SGX For VMs, Apple Silicon, More RISC-V
This week marked the release of QEMU 6.2-rc0 as the first test candidate for this upcoming update that plays an important role in the open-source Linux virtualization stack...
Mesa's Turnip Driver For Qualcomm Adreno GPUs Now Exposes Vulkan 1.2
Mesa's open-source "Turnip" driver that provides Vulkan support for Qualcomm Adreno graphics hardware and complementary to the Freedreno Gallium3D driver can now handle Vulkan 1.2...
Modernized Zstd Merged Into Linux 5.16 For Much Greater Performance
While Zstd is used in various areas of the Linux kernel for data compression from transparent file-system compression with the likes of Btrfs to allowing kernel modules be compressed with this Zstandard algorithm, the in-kernel code had fallen years outdated. Finally with Linux 5.16 that Zstd in-kernel implementation is now being brought up to modern standards and delivering better performance too...
Microsoft Has More SMB3/CIFS Enhancements For Linux 5.16, Including For Performance
Another batch of SMB3/CIFS client changes were submitted and merged today for the Linux 5.16 merge window. Plus the KSMBD changes were also merged today for that in-kernel SMB3 file server...
