A method, system and computer program product are provided for implementing distributed debug data collection and analysis for a hardware I/O adapter, such as, a Single Root Input/Output Virtualization (SRIOV) adapter in a virtualized system. A predetermined event triggers a base error collection sequence. Adapter driver data is collected and virtual function (VF) device drivers are locked out responsive to triggering the base error collection sequence. Adapter debug data is collected and the adapter is reinitialized including an indication to VF drivers if VF error data is to be collected. The virtual function (VF) device drivers are unlocked allowing the VF device drivers to commence recovery of a respective virtual function (VF).

A method, compiler and platform independent framework are provided for parsing and generating data structures. Size of and offsetof functions are utilized for defining a length and a location of each parameter of a data structure. The length and location of each parameter of the data structure are stored within an identifier object in a data structure definition. The identifier structure is based on the definition of the data structure itself so that the problem of duplicating the data structure definition is eliminated. The sizeof and offsetof functions automatically account for compiler and platform differences which otherwise would lead to alignment problems so that compiler and platform independence from data structure realignment is provided.

According to the preferred embodiments of the present invention, a method and an apparatus for efficiently and accurately processing incoming connection establishment requests is disclosed. The present invention allows the signaling provider of the network interface software to determine ownership of an incoming request by accessing client-provided information in the form of call filters. Upon receiving an incoming call establishment request, the network interface software matches the request to information previously provided by the clients of the network interface software. The network interface software can thus determine the correct recipient, negotiate parameters on the owner's behalf, establish a call connection, inform the client that the connection has been established, and inform the client of specific parameters relating to the incoming call.

A method and apparatus are disclosed for providing an inline data service within a data processing system coupled to a communications network. The data processing system includes a host memory. According to the present invention, the apparatus comprises an adapter memory for temporarily storing data communicated between the data processing system and the communications network and a memory access controller, which controls transfers of data between the adapter memory and the host memory. The apparatus further includes means for selectively performing a data transformation on data transferred between the adapter memory and the host memory, wherein the data transformation is performed during a transfer of the data such that data communication latency is reduced. In a second preferred embodiment of the present invention, a multibus data processing system has a processor and a first memory coupled to a first bus and a second memory coupled to a second bus. A bridge adapter, including means for transferring data from the first memory to the second memory and means for selectively performing a data transformation, is coupled between the first and second buses. During transfers of data from the first memory to the second memory, the bridge adapter selectively performs data transformations on the data, such that data processing latency is reduced.

A system for supporting graphics display sessions on remote terminals contains a processing subsystem dedicated to graphics support. Applications execute on a central processor, and display related graphics commands are executed on the separate graphics controller subsystem. The graphics subsystem is preferably connected to multiple remote terminals over a network, and communicates with them without requiring all work to be performed by the central processor which is executing the applications.

Display station controller

A large communications network is linked to a primary terminal and a secondary terminal. The primary polls the secondary whenever it has data to send, and need not poll at any maximum fixed interval. The poll operation sends a sequence of data frames to the secondary, and causes the secondary to return to the primary a sequence of frames containing any data it may have ready. The secondary can only send data to the primary in response to a poll operation; however, the secondary has the capability of sending a uniquely identifiable frame on its own initiative whenever it has data ready to send and has not received a poll. This frame causes the primary to initiate a normal poll even though it has no data ready to send.

Polling-type digital communications system having pseudo-balanced mode

A method and computer system having a processor are provided for selectively compressing a data communication frame for data transfer between the computer system and at least one other system. A processor work load is periodically identified for the processor. A predetermined stored threshold value is identified and compared with the identified processor work load. Responsive to an identified processor work load greater than the identified predetermined threshold value, the data communication frame is transmitted without compressing the data communication frame. Otherwise the data communication frame is compressed and then transmitted responsive to an identified processor work load less than or equal to the identified predetermined threshold value. A state of a communication line is identified for the data transfer. Responsive to an identified idle state of the communication line, the data communication frame is transmitted without compressing the data communication frame.
