摘要： Described are techniques for intermodule communication between a first code module and a second code module wherein one of the first and second code modules executing in user space and the other of the first and second code modules executing in kernel space. A shared memory portion includes storage for one or more commands. A first first-in-first-out (FIFO) structure is used to send a location in the shared memory portion from the first to the second code module. A second FIFO structure is used for sending a location in the shared memory portion from the second to the first code module. The first code module stores command data for a command at a first location in the shared memory portion. A command is issued from the first to the second code module by sending the first location using the first FIFO structure.

摘要： Described are techniques for communicating between one or more producers and one or more consumers. A first consumer of an event queue registers for notification regarding occurrences of one or more events. A producer of the event queue posts one or more notifications to one or more consumers of the event queue regarding one or more occurrences of one or more events. Each of the consumers receive notification regarding occurrences of events for which said each consumer is registered. The first consumer retrieves posted event notifications regarding events for which said first consumer is registered. If the first consumer is executing in user space and an event notification list to which said event notifications for said first consumer are posted is located in shared memory, said first consumer retrieves said posted event notifications without proxying into kernel space.

摘要： Described are techniques for processing a module. A module is generated for execution on a target operating system. The module includes four entry points and code portions associated with each of said four entry points. The four entry points correspond to four handlers invoked at different processing points in connection with a state associated with said module. The four handlers include a load handler, an unload handler, a start handler, and a quiesce handler. First processing is performed in connection with the module. The first processing including at least one of dynamically loading the module, dynamically unloading the module, starting module-specific processing performed by the module, and issuing a request to commence preparation for unloading the module. An appropriate one or more of the four handlers are invoked in accordance with the first processing performed.

摘要： Described are techniques for performing remote procedure calls (RPCs). An RPC API is described which provides for using an optimized technique and an unoptimized technique for performing RPCs. The optimized technique includes a client container performing a call to obtain RPC configuration information which is then stored by the client container and may be used by the client container in connection with multiple RPC invocations. Techniques are also described for communicating parameter information between containers executing in different address spaces by forming parameter information on the client side using embedded lists, encoding the parameter information on the client side prior to transmission to the server, and transmitting the encoded parameter information to the server which determines output parameters and returns the output parameters to the client.

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 synchronizing processing of at least two code threads. A first thread executing in user space is provided. A second thread executing in kernel space is provided. A global mutex lock is provided for synchronizing processing between said first thread and said second thread. One of said first thread and said second thread holds the global mutex lock and is identified as a current owner of the global mutex lock. The other of said first thread and said second thread requests the global mutex lock and is blocked until the current owner of the global mutex lock releases the global mutex lock. The global mutex lock is held by at most one thread at a point in time and is identified as the current owner.

摘要： Described are techniques for intermodule communication between a first code module and a second code module each executing in user space. A shared memory portion includes storage for one or more commands and is accessible to the first and the second code modules. A first first-in-first-out (FIFO) structure is used for sending a location in the shared memory portion from the first code module to the second code module. A second FIFO structure is used for sending a location in the shared memory portion from the second code module to the first code module. The first code module stores command data for a command at a first location in the shared memory portion. A command is issued from the first code module to the second code module by sending the first location from the first code module to the second code module using the first FIFO structure.

摘要： Described are techniques for building a code entity. A plurality of configuration files are selected in accordance with a target and target variant. The target identifies hardware and software platform information about an environment in which the code entity is to be configured for execution. The target variant identifies a software build variation for a particular target. One or more build phases are performed using the plurality of configuration files selected in said selecting. The code entity is generated as an output of performing the one or more build phases where the code entity varies with the target and target variant.
