    摘要: A method and apparatus for invalidating entries within a translation control entry (TCE) cache are disclosed. A host bridge is coupled between a group of processors and a group of adaptors. The host bridge includes a TCE cache. The TCE cache contains the most-recently use copies of TCEs in a TCE table located in a system memory. In response to a modification to a TCE in the TCE table by one of the processors, a memory mapped input/output (MMIO) Store is sent to a TCE invalidate register to specify an address of the modified TCE. The data within the TCE invalidate register is then utilized to generate a command for invalidating an entry in the TCE cache containing an unmodified copy of the modified TCE in the TCE table. The command is subsequently sent to the host bridge to invalidate the entry in the TCE cache.

    摘要: A method, system, and computer usable program product for scaling energy use in a virtualized data processing environment are provided in the illustrative embodiments. A set of PIOAs is configured such that each PIOAs in the set of PIOAs is a functional equivalent of another PIOAs in the set of PIOAs. A utilization of each PIOA in the set of PIOAs is measured. A number of PIOAs needed to service a workload is determined. A first subset of PIOAs from the set of PIOAs is powered down if the number of PIOAs needed to service the workload is smaller than a number of operational PIOAs. The I/O operations associated with the first subset of PIOAs are transferred to a second subset of PIOAs remaining operational in the set of PIOAs.

    摘要: A method, system, and computer-usable medium for supporting debugging of host channel adapters in a logical partitioning environment. In a preferred embodiment of the present invention, a hypervisor acquires control of a trace facility and sets trace parameters for the host channel adapter. In response to determining a trace event that matches said trace parameter has been triggered, the hypervisor retrieves trace information from a buffer. In response to determining the buffer does not include any more trace information, the hypervisor determines if modification of the trace parameters is required. If the modification of the trace parameters is required, the hypervisor alters the trace parameters in anticipation of another trace event.
