Abstract: The following description is directed to a logic repository service. In one example, a method of a logic repository service can include receiving a first request to generate configuration data for configurable hardware using a specification for application logic of the configurable hardware. The method can include generating the configuration data for the configurable hardware. The configuration data can include data for implementing the application logic. The method can include encrypting the configuration data to generate encrypted configuration data. The method can include signing the encrypted configuration data using a private key. The method can include transmitting the signed encrypted configuration data in response to the request.

Abstract: The following description is directed to a configurable logic platform. In one example, a configurable logic platform includes host logic and a plurality of reconfigurable logic regions. Each reconfigurable region can include hardware that is configurable to implement an application logic design. The host logic can be used for separately encapsulating each of the reconfigurable logic regions. The host logic can include a plurality of data path functions where each data path function can include a layer for formatting data transfers between a host interface and the application logic of a corresponding reconfigurable logic region. The host interface can be configured to apportion bandwidth of the data transfers generated by the application logic of the respective reconfigurable logic regions.

Abstract: Techniques are described for managing virtual machines using input/output (I/O) device logging. For example, a system bus or other interface to a device may be monitored for traffic data elements. The traffic data elements may include, for example, transaction layer packets (TLPs) for communication across a PCI Express interface, or TCP/IP packets for communication over a network. These traffic data elements may be logged in an I/O device logging buffer. The I/O device logging buffer can then be used to ensure that all memory relating to a virtual machine is copied when transferring the virtual machine to another computing device. In addition, the I/O device logging buffer can be used to stop a virtual machine without waiting for the virtual machine to complete I/O processing.
