    摘要： A method for facilitating direct memory access in a computing system in response to a request to transfer data is provided. The method comprises selecting a thread for transferring the data, wherein the thread executes on a processing core within the computing system; providing the thread with the request, wherein the request comprises information for carrying out a data transfer; and transferring the data according to the request. The method may further comprise: coordinating the request with a memory management unit, such that virtual addresses may be used to transfer data; invalidating a cache line associated with the source address or flushing a cache line associated with the destination address, if requested. Multiple threads can be selected to transfer data based on their proximity to the destination address.

    摘要： A method and system for memory address translation and pinning are provided. The method includes attaching a memory address space identifier to a direct memory access (DMA) request, the DMA request is sent by a consumer and using a virtual address in a given address space. The method further includes looking up for the memory address space identifier to find a translation of the virtual address in the given address space used in the DMA request to a physical page frame. Provided that the physical page frame is found, pinning the physical page frame al song as the DMA request is in progress to prevent an unmapping operation of said virtual address in said given address space, and completing the DMA request, wherein the steps of attaching, looking up and pinning are centrally controlled by a host gateway.

    摘要： A computer-implemented method for protecting a memory is provided. The method includes responsive to a direct memory access (DMA) request received from a consumer for a transaction of data from an IO device to the memory, the request including an IO command and a capability (CAP), generating a cryptographically signed capability (CAPB), forming a credential from CAP and CAPB, appending the credential to the IO command, configuring the IO device according to the credential and the IO command, transmitting the data from the IO device to the memory and prior to allowing execution of the DMA, authenticating that the credential is valid, further includes regenerating CAPB from a key available to an authenticating entity and from the CAP (included in CAPB) and verifying that the memory region information described in the cryptographically signed capability is the same as the requested region that was originally created, and that the cryptographically signed capability encompasses the IO command.
