Enhanced apparatuses, systems, and techniques for coupling network-linked peripheral devices into host computing devices is presented. A method includes, over a network interface of a host device, obtaining an indication of a peripheral device available for associating with the host device. Based on the indication, the method includes initiating instantiation of the peripheral device into a Peripheral Component Interconnect Express (PCIe) subsystem of the host device by at least emulating behavior of the peripheral device over the network interface as a PCIe peripheral device coupled locally to the host system.

A method of sharing a resource using a virtual device driver and an electronic device thereof are provided. The method includes generating a virtual device driver, which corresponds to a real device driver of a host electronic device, in the client electronic device, receiving a resource from the host electronic device by using the virtual device driver through a first communication mechanism designated in the host electronic device, and after the first communication mechanism is changed to a second communication mechanism designated in the host electronic device, receiving the resource from the host electronic device by using the virtual device driver.

A method for managing a memory of a virtual machine, a physical host, a PCIE device and a configuration method thereof are provided. The method executed by a virtual machine includes: allocating a memory to a service carried on a PCIE device, where the memory includes multiple memory blocks, the multiple memory blocks is used to save working information of the service; generating a base address table BAT and a chip logic address table CLAT, where the BAT includes a CLAT entry base address corresponding to the service, and the CLAT includes a first address of each memory block; and sending an address of the BAT and a function number corresponding to the virtual machine to the PCIE device. Therefore, the PCIE device can obtain, according to the address of the BAT and the function number, working information of a service from the virtual machine.

A method, system and computer program product are provided for implementing dynamic cost calculation for a Single Root Input/Output Virtualization (SRIOV) virtual function (VF) in cloud environments. A management function periodically queries the SRIOV adapter for activity statistics for each assigned virtual function. The management function builds a usage heuristic based on the resource usage statistics. The management function calculates dynamic cost for the SRIOV VF based on the resource usage statistics. Calculated dynamic costs for the SRIOV VF are provided to a virtual function user and users are enabled to scale their VF resources. The VF resources are selectively scaled-up and scaled-down responsive to user input based upon VF resource usage.

A method and electronic device are disclosed herein. The electronic device includes at least one connector, at least one switch electrically connected to the at least one connector, a sensor, a memory, and a processor electrically connected to the at least one connector, the at least one switch, the sensor, and the memory. The processor implements the method, including detecting insertion of an external device into the at least one connector based on an electrical signal input through the at least one connector, receiving biometric information using the sensor after detecting the insertion of the external device, and controlling a switch electrically connected to the connector to be connected to the connector into which the external device is inserted when the received biometric information matches biometric information stored in the memory.

A management engine may be used to trap configuration cycles during the boot process and thereafter in response to operating system enumeration. As a result, a virtual bus device can be created. The bus device may be used to provision software to the platform even when the operating system is corrupted or non-functional.

A portable electronic device includes a housing including a computer communication interface and a controller configured for generating, onboard the portable electronic device, a current measure of dynamic information. The portable electronic device also includes a memory storing the current measure and a website address. The controller includes a keyboard emulator providing keystroke data over the computer communication interface to launch an internet browser, navigate to the website address, and transmit the current measure. A specific device driver does not need to be installed on a computer for the portable electronic device to automatically launch the internet browser, navigate to the website address, and transmit the current measure when the portable electronic device is connected to communicate with the computer.

A node on a serial bus, preferably a device such as a personal computer (PC), can emulate other devices using virtual device drivers. A PC connected to a 1394 bus exposes its CROM on the bus which presents an image to other nodes on the 1394 bus and describes the functional units supported by the node. The CROM can be changed dynamically by adding unit directories to the CROM detailing peripherals connected to the PC. The PC can then be enumerated as the connected device by other PCs on the bus. The PC can emulate or morph itself into any desired device or even multiple devices at the same time. The invention also allows a PC to create devices that don't yet exist on the bus. The invention allows a user to create virtual device objects with device properties to have just in case a user plugs the particular device in to the PC.

In a method for SR-IOV Virtual Functions Sharing on Multi-Hosts, implemented in a management system, one or more fake devices are simulated in one or more hosts with each fake device corresponding to one of a plurality of SR-IOV virtual functions. Each of one or more configuration spaces is redirected from each SR-IOV virtual function to each fake device, respectively. Each of configuration space requests is redirected from a corresponding fake device to a corresponding SR-IOV virtual function when the configuration space request is received. And each of memory access operations is redirected from the corresponding SR-IOV virtual function to a mapped memory on a corresponding host with the corresponding fake device, and each of interrupts generated by one or more SR-IOV virtual machines is redirected to the corresponding fake device.

In accordance with some aspects of the present disclosure, a non-transitory computer readable medium is disclosed. In some embodiments, the non-transitory computer readable medium includes instructions that, when executed by a processor, cause the processor to receive, from a workload hosted on a host of a cluster, first I/O traffic programmed according to a first I/O traffic protocol supported by a cluster-wide storage fabric exposed to the workload as being hosted on the same host. In some embodiments, the workload is recovered by a hypervisor hosted on the same host. In some embodiments, the non-transitory computer readable medium includes the instructions that, when executed by the processor, cause the processor to adapt the first I/O traffic to generate second I/O traffic programmed according to a second I/O traffic protocol supported by a repository external to the storage fabric and forward the second I/O traffic to the repository.
