If they go through check_loader_disabled_ap(), then I'm inclined to set dis_ucode_ldr to true at build time and let check_loader_disabled_bsp() set it to false on baremetal or if any of the other checks pass. If the pv guests run into check_loader_disabled_ap, then they'll see dis_ucode_ldr true and return. Ok? -- Regards/Gruss, Boris.
