摘要： Method, apparatus and system for isolating input/output adapter error domains in a data processing system. Errors occurring in one input/output adapter are isolated from other input/output adapters of the data processing system by functionality in a host bridge that connects the input/output adapters to a system bus of the data processing system, thus permitting the use of low cost, industry standard switches and bridges external to the host bridge.

摘要： A method, computer program product, and distributed data processing system that allows a system image within a multiple system image virtual server to directly expose a portion, or all, of its associated system memory to a shared PCI adapter without having to go through a trusted component, such as a Hypervisor. Specifically, the present invention is directed to a mechanism for sharing conventional PCI I/O adapters, PCI-X I/O Adapters, PCI-Express I/O Adapters, and, in general, any I/O adapter that uses a memory mapped I/O interface for communications.

摘要： Registering memory space within a data processing system is performed. One or more open calls are received from an application to access one or more input/output (I/O) devices. Responsive to receiving the one or more open calls, one or more I/O map and pin calls are sent in order to register memory space for the one or more I/O devices within at least one storage area that will be accessed by the application. At least one virtual I/O bus address is received for each registered memory space of the one or more I/O devices. At least one I/O command is executed using the at least one virtual I/O bus address without intervention by an operating system or operating system image.

摘要： Registering memory space for an application is performed. One or more open calls are received from an application to access one or more input/output (I/O) devices. Responsive to receiving the one or more open calls, one or more I/O map and pin calls are sent in order to register memory space for the one or more I/O devices within at least one storage area that will be accessed by the application. A verification is made as to whether the memory space to be registered is associated with the application. Responsive to the memory space being associated with the application, at least one virtual I/O bus address is received for each registered memory space of the one or more I/O devices. At least one I/O command is executed using the at least one virtual I/O bus address without intervention by an operating system or operating system image.

摘要： A message signaled interrupt (MSI) specifying an input/output (I/O) address in I/O address space is received. In response to receipt of the MSI, a translation data structure is accessed and the I/O address is translated into a physical memory address by reference to the translation data structure. The MSI is then enqueued in an event queue at the physical memory address for subsequent servicing.

摘要： Disclosed is a computer implemented method, computer program product, and apparatus to establish at least one paging partition in a data processing system. The virtualization control point (VCP) reserves up to the subset of physical memory for use in the shared memory pool. The VCP configures at least one logical partition as a shared memory partition. The VCP assigns a paging partition to the shared memory pool. The VCP determines whether a user requests a redundant assignment of the paging partition to the shared memory pool. The VCP assigns a redundant paging partition to the shared memory pool, responsive to a determination that the user requests a redundant assignment. The VCP assigns a paging device to the shared memory pool. The hypervisor may transmit at least one paging request to a virtual asynchronous services interface configured to support a paging device stream.
