Add this vcpu_affinity[] for each VM to indicate the assignment policy. With it, pcpu_bitmap is not needed, so remove it from vm_config. Instead, vcpu_affinity is a must for each VM. This patch also add some sanitize check of vcpu_affinity[]. Here are some rules: 1) only one bit can be set for each vcpu_affinity of vcpu. 2) two vcpus in same VM cannot be set with same vcpu_affinity. 3) vcpu_affinity cannot be set to the pcpu which used by pre-launched VM. v4: config SDC with CONFIG_MAX_KATA_VM_NUM v5: config SDC with CONFIG_MAX_PCPU_NUM Tracked-On: #3663 Signed-off-by: Jason Chen CJ <jason.cj.chen@intel.com> Signed-off-by: Yu Wang <yu1.wang@intel.com> Signed-off-by: Shuo A Liu <shuo.a.liu@intel.com>
