    Abstract: Computing apparatus includes a central processing unit (CPU), which is configured to run concurrently multiple virtual machines, including at least first and second virtual machines. A peripheral component bus is connected to communicate with the CPU. Multiple peripheral devices are connected to communicate via the bus with the CPU and with others of the peripheral devices, including at least first and second peripheral devices that are each respectively partitioned into at least first and second functional entities, which are respectively assigned to serve the at least first and second virtual machines. Access control logic is configured to forward peer-to-peer communications initiated by the functional entities between the peripheral devices over the bus while inhibiting access in the peer-to-peer communications between the functional entities that are assigned to different ones of the virtual machines.

    Abstract: A method includes communicating between at least first and second devices over a bus in accordance with a bus address space, including providing direct access over the bus to a local address space of the first device by mapping at least some of the addresses of the local address space to the bus address space. In response to indicating, by the first device or the second device, that the second device requires to access a local address in the local address space that is not currently mapped to the bus address space, the local address is mapped to the bus address space, and the local address is accessed directly, by the second device, using the mapping.

    Abstract: A method for data transfer includes receiving in an operating system of a host computer an instruction initiated by a user application running on the host processor identifying a page of virtual memory of the host computer that is to be used in receiving data in a message that is to be transmitted over a network to the host computer but has not yet been received by the host computer. In response to the instruction, the page is loaded into the memory, and upon receiving the message, the data are written to the loaded page.

    Abstract: A method for data transfer includes receiving in an input/output (I/O) operation a first segment of data to be written to a specified virtual address in a host memory. Upon receiving the first segment of the data, it is detected that a first page that contains the specified virtual address is swapped out of the host memory. At least one second page of the host memory is identified, to which a second segment of the data is expected to be written. Responsively to detecting that the first page is swapped out and to identifying the at least one second page, at least the first and second pages are swapped into the host memory. After swapping at least the first and second pages into the host memory, the data are written to the first and second pages.

    Abstract: A method for memory access includes maintaining in a host memory, under control of a host operating system running on a central processing unit (CPU), respective address translation tables for multiple processes executed by the CPU. Upon receiving, in a peripheral device, a work item that is associated with a given process, having a respective address translation table in the host memory, and specifies a virtual memory address, the peripheral device translates the virtual memory address into a physical memory address by accessing the respective address translation table of the given process in the host memory. The work item is executed in the peripheral device by accessing data at the physical memory address in the host memory.
