/proc/cpuinfo shows the current microcode version
- negura 5mo agoi don't think the information that unprivilleged VMs can obtain from that is necessarily reliable. for example with Xen as hypervisor only dom0 is privilleged (as management console for the system) and still it needs to call dedicated tooling in order to read or manage CPU features like clock speed or frequency scaling
