An updated Linux patch aims to disable the RDSEED instruction across all AMD Zen 5 CPUs. This change targets potential security or compatibility issues in the processor architecture. The proposal comes from the Linux kernel development community.
The updated Linux patch, as reported by Phoronix, would disable RDSEED for all AMD Zen 5 CPUs. RDSEED is a hardware instruction used for generating random numbers, often in cryptographic applications.
Phoronix covers Linux hardware reviews, benchmarks, and open-source developments, including this patch update. The site specializes in Desktop Linux, Ubuntu hardware testing, and performance analysis.
No specific timeline, developer names, or detailed reasons for the disablement are provided in the source. The patch focuses on Zen 5, AMD's latest CPU architecture.
This development highlights ongoing efforts to address hardware-specific features in Linux kernels for stability and security.
