AMX is an x86 extension adding hardware units for matrix operations (int and float dot products). The goal of the extension is to provide performance enhancements for these common operations. On Linux, AMX requires requesting the permission from the kernel prior to use. Guests wanting to make use of the feature need to have the request made prior to starting the vm. This change then adds the first --cpus features option amx that when passed will enable AMX usage for guests (needs a 5.17+ kernel) or exits with failure. The activation is done in the CpuManager of the VMM thread as it allows migration and snapshot/restore to work fairly painlessly for AMX enabled workloads.
