    IPC: G06F20060101

    Abstract: A computer implemented instruction is executed. One or more translation table entry locations (TLB) are specified by the instruction. Based on a local-clearing (LC) control specified by the instruction being a first value, the processor selectively clears TLBs in a plurality of the CPUs in a configuration of entries corresponding to the determined translation table entry location. Based on the local-clearing (LC) being a second value, the processor selectively clears only the TLBs of the CPU executing the instruction of entries corresponding to the determined translation table entry location. A computer program product, computer system and computer implemented method are provided.

    Abstract: A first and a second operand are compared. If they are equal, the contents of register R1+1 are stored at the second-operand location, and the specified CPU or CPUs in the configuration are cleared of all TLB table entries of the designated type formed through the use of the replaced entry in storage, and all lower-level TLB table entries formed through the use of the cleared higher-level TLB table entries. A valid DAT table entry is replaced with a new entry, and the Translation Lookaside Buffer (TLB) is purged of any copies of (at least) the single entry on all CPUs in the configuration. If the first and second operands are unequal, the second operand is loaded at the first-operand location. The comparison result is indicated by the condition code. A method, system and a computer program product are provided.

    IPC: G06F20060101

    Abstract: Program exception conditions cause a transaction to abort and typically result in an interruption in which the operating system obtains control. A program interruption filtering control is provided to selectively present the interrupt. That is, the interrupt from the program exception condition may or may not be presented depending at least on the program interruption filtering control and a transaction class associated with the program exception condition. The program interruption filtering control is provided by a TRANSACTION BEGIN instruction.

    IPC: G06F20060101

    Abstract: An address provided in a request issued by an adapter is converted to an address directly usable in accessing system memory. The address includes a plurality of bits, in which the plurality of bits includes a first portion of bits and a second portion of bits. The second portion of bits is used to index into one or more levels of address translation tables to perform the conversion, while the first portion of bits are ignored for the conversion. The first portion of bits are used to validate the address.
