    摘要： Described are techniques for executing code performing one or more operations corresponding to scheduling and synchronization primitives. During execution of the code, a call is performed using an application programming interface requesting a first of the operations corresponding to one of said scheduling and synchronization primitives. During runtime in response to said call, it is determined whether to perform the first operation. The determining step uses a set of one or more criteria indicating conditions as to when the scheduling and synchronization primitives are allowed to be performed. The one or more criteria are determined in accordance with a plurality of different platforms. If it is determined that the first operation is allowable and the first operation is to be performed, then the code can be executed on each of the different platforms in a privileged execution mode and a non-privileged execution mode.

    摘要： Described are techniques for facilitating communication between code modules. A first code module is provided that makes at least one call using an application programming interface. The application programming interface facilitates communication between the first code module and a target code module and provides support for performing the at least one call from a first execution mode associated with the first code module and a second execution mode associated with the target code module. The application programming interface provides support for user space to user space communication, user space to kernel space communication, kernel space to kernel space communication, and kernel to user space communication. The first execution mode of the first code module and said second execution mode of the target code module are determined. A communication path is established between the code modules in accordance with the first and second execution modes.

    摘要： Described are techniques for facilitating communication between device drivers. A device driver is provided that makes at least one call using an application programming interface. The application programming interface facilitates communication between the device driver module and a target code module. The application programming interface provides support for performing the at least one call from a first execution mode associated with the device driver module and a second execution mode associated with the target code module. The application programming interface provides support for user space to user space communication, user space to kernel space communication, kernel space to kernel space communication, and kernel to user space communication. The first execution mode of the device driver module and said second execution mode of the target code module are determined. A communication path between the modules is established in accordance with said first execution mode and said second execution mode.
