The Surprising Spectre BHI Mitigation Performance Impact On Meteor Lake

12 janvier 2026 à 18:38
When recently carrying out performance benchmarks of Intel Meteor Lake performance on Linux since launch day two years ago, the geo mean came in at 93% the original performance. Finding the performance trending clearly lower with an up-to-date Linux software stack compared to in December 2023 was quite surprising considering the rather nice gains we have seen over time on other Intel/AMD hardware. As noted in that article though, one of the possible explanations there is the Spectre BHI "Branch History Injection" vulnerability and microcode plus Linux kernel mitigations having come out post-launch and affecting Meteor Lake CPUs. Sure enough, follow-up tests looking at the Spectre BHI impact have revealed a measurable cost in a number of workloads for the Core Ultra processor.

Linux Lands Safeguard For RISC-V Against Another Microarchitectural Attack Vector

11 janvier 2026 à 11:34
Increasingly complex RISC-V cores aren't magically immune to the speculative execution / side-channel vulnerabilities that have rattled the x86_64 and ARM64 landscape for years. Following recent work on Spectre V1 handling for RISC-V in the Linux kernel, merged this weekend for Linux 6.19-rc5 is another RISC-V attack vector safeguard...
