摘要： Provided are a method, system, and program for configuring shared devices over a fabric. A module in a first processing complex configures a first part of a fabric enabling communication with a set of devices accessible through the first part of the fabric. The module detects a located device accessible through a second part of the fabric, wherein a second processing complex is designated to configure the second part of the fabric and the located device. The module determines whether the second processing complex is available in response to detecting the uninitialized device. The module passes to a device driver in the first processing complex an uninitialized property for the located device. The device driver requests the module to configure the second part of the fabric to enable access to the located device over the second part of the fabric in response to determining that the located device has the uninitialized property.

摘要： Provided are a method, system, and program for handling a fabric failure. A module intercepts a signal indicating a failure of a path in a fabric providing a connection to a shared device. The module generates an interrupt to a device driver in an operating system providing an interface to the shared device that is inaccessible due to the path failure. The device driver requests information from the module on a status of a plurality of devices that are not accessible due to the path failure and receives information indicating the inaccessible device. The device driver reconfigures to discontinue use of the inaccessible device.

摘要： A determination is made as to whether a configuration indicator associated with a resource indicates a delayed configuration of the resource, wherein the resource is shared by a plurality of processing complexes via a bus, and wherein if the delayed configuration of the resource is indicated then the resource is prevented from being configured during initial program loads of the plurality of processing complexes. The resource is configured by only one of the of plurality of processing complexes that shares the resource, in response to determining that the configuration indicator associated with the resource indicates the delayed configuration of the resource.

摘要： In managing multiprocessor operations, a first processor repetitively reads a cache line wherein the cache line is cached from a line of a shared memory of resources shared by both the first processor and a second processor. Coherency is maintained between the shared memory line and the cache line in accordance with a cache coherency protocol. In one aspect, the repetitive cache line reading occupies the first processor and inhibits the first processor from accessing the shared resources. In another aspect, upon completion of operations by the second processor involving the shared resources, the second processor writes data to the shared memory line to signal to the first processor that the shared resources may be accessed by the first processor. In response, the first processor changes the state of the cache line in accordance with the cache coherency protocol and reads the data written by the second processor. Other embodiments are described and claimed.
