The long-in-development Bcachefs file-system driver was submitted for Linux 6.5 but never merged this cycle due to various technical issues and developer in-fighting. Linus Torvalds himself has now gotten around to reviewing the proposed code and chiming in on the situation…

The intel-speed-select tool that lives within the Linux kernel source tree has seen a set of patches prepared for the upcoming Linux 6.6 merge window. Arguably most interesting with this updated Intel Speed Select tool is now the ability to work with more than eight CPU sockets per platform — the new limit is 32…

As soon as the AMD Inception CPU vulnerability was made public yesterday, the Linux kernel mitigation patches were merged and within hours appeared in six new stable point releases for the kernel along with the Intel Downfall mitigation patches. Today though these patches are seeing a rework to clean-up this mitigation…

In addition to the Linux kernel patches for GDS/Downfall for reporting the mitigated state and handling around Intel’s latest speculative execution vulnerability, the updated CPU microcode has now been published on GitHub. In addition to having the Downfall mitigations for Skylake through Icelake/Tigerlake, there are also other security updates and functional issues resolved by this Intel 20230808 CPU microcode release…

This Patch Tuesday brings a new and potentially painful processor speculative execution vulnerability… Downfall, or as Intel prefers to call it is GDS: Gather Data Sampling. GDS/Downfall affects the gather instruction with AVX2 and AVX-512 enabled processors. At least the latest-generation Intel CPUs are not affected but Tigerlake / Ice Lake back to Skylake is confirmed to be impacted. There is microcode mitigation available but it will be costly for AVX2/AVX-512 workloads with GATHER instructions in hot code-paths and thus widespread software exposure particularly for HPC and other compute-intensive workloads that have relied on AVX2/AVX-512 for better performance.
