Disclosed back in March 2022 was Branch History Injection (BHI) as a new Spectre vulnerability affecting Intel and Arm CPUs. Then in July of 2022 were patches for Intel working on hardware-based prevention for Spectre-BHI attacks. Now two years later the Linux kernel is seeing mitigations added for the native Branch History Injection vulnerability given a new "Native BHI" variant...

Intel is using its Vision 2024 conference in Arizona today to announce the Gaudi 3 AI accelerator. With Gaudi 3 comes some rather bold AI claims from Intel: 50% on average better inference and 40% on average better power efficiency than the NVIDIA H100. All while costing "a fraction" of the NVIDIA H100. Gaudi 3 sounds quite promising and will be interesting to see how its adopted in the marketplace. In addition, Intel also is disclosing the new Xeon 6 branding for their upcoming server processors formerly codenamed Sierra Forest and Granite Rapids.

For confidential computing "CoCo" virtual machines where the VM host is assumed to be un-trusted and aims to be as isolated as possible, RdRand hardware random number generator instructions are one of the limited sources of entropy for guest VMs. Right now RdRand can fail and the CoCo guest VMs will continue to boot albeit with limited or no entropy to see the VM's random number generation. But being merged today as part of x86 fixes for Linux 6.9 is now requiring seeding RNG with RdRand for CoCo environments otherwise a kernel panic...

Last week being surprised to see a number of AMD EPYC performance gains with Linux 6.9 using that in-development kernel, I was curious about what other platforms may be benefiting from better performance on this kernel that will debut as stable in May. This week I turned to running some fresh benchmarks of Intel Xeon Max using the Supermicro Hyper SuperServer SYS-221H-TNR. More than 230 benchmarks were carried out of Linux 6.8 stable versus Linux 6.9-rc2 in looking for any performance differences.
