--- Comment #15 from GGanesh <Ganesh.Gopalasubramanian at amd dot com> --- I wanted to get it confirmed from our BIOS and Kernel developer manuals (https://www.amd.com/content/dam/amd/en/documents/archived-tech-docs/programmer-references/50742_15h_Models_60h-6Fh_BKDG.pdf). RDRAND is *supported*/*enabled* for Models 60h-6Fh. However, since the latest kernel code is not setting it unconditionally, we can only rely on the cpuid bits enabled by Kernel. If it is disabled, I personally feel we need to remove it from the list of ISAs supported by Excavator in gcc as well.
