A first device is configured to “ring” a “doorbell” of a second device, where both the first and second devices are not a host processor such as a central processing unit and are coupled to an interconnect fabric such as peripheral component interconnect express (“PCIe”). The first device is configured to ring the doorbell of the second device by writing to a doorbell address in a guest physical address space. For security reasons, a check block checks an offset portion of the doorbell address against a set of allowed doorbell addresses for doorbells specified in the guest physical address space, allowing the doorbell to be written if the doorbell is included in the set of allowed doorbell addresses."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Direct doorbell ring in virtualized processing device","description":"A technique for facilitating direct doorbell rings in a virtualized system is provided.
