Abstract
Portions of configuration state registers in-memory. An instruction is obtained, and a determination is made that the instruction accesses a configuration state register. A portion of the configuration state register is in-memory and another portion of the configuration state register is in-processor. Processing associated with the configuration state register is performed. The performing processing is based on a type of access and whether the portion or the other portion is being accessed.
Claims20
A computer program product for facilitating processing within a computing environment, the computer program product comprising:
- a computer readable storage medium readable by a processing circuit and storing instructions for performing a method comprising:
- obtaining an instruction;
- determining that the instruction accesses a configuration state register, in which a portion of the configuration state register is in-memory and another portion of the configuration state register is in-processor;
- and
- performing processing associated with the configuration state register, the performing processing being based on a type of access and whether the portion or the other portion is being accessed, wherein the type of access comprises a move to configuration state register and wherein the performing processing comprises:
- generating a first set of internal operations based on the portion of the configuration state register that is in-memory;
- generating a second set of internal operations based on the other portion of the configuration state register that is in-processor;
- and
- executing at least one of the first set of internal operations and the second set of internal operations.
A computer system for facilitating processing within a computing environment, the computer system comprising:
- a memory;
- and
- a processor in communication with the memory, wherein the computer system is configured to perform a method, said method comprising:
- obtaining an instruction;
- determining that the instruction accesses a configuration state register, in which a portion of the configuration state register is in-memory and another portion of the configuration state register is in-processor;
- and
- performing processing associated with the configuration state register, the performing processing being based on a type of access and whether the portion or the other portion is being accessed, wherein the type of access comprises a move to configuration state register, and wherein the performing processing comprises:
- generating a first set of internal operations based on the portion of the configuration state register that is in-memory;
- generating a second set of internal operations based on the other portion of the configuration state register that is in-processor;
- and
- executing at least one of the first set of internal operations and the second set of internal operations.
A computer-implemented method of facilitating processing within a computing environment, the computer-implemented method comprising:
- obtaining an instruction;
- determining that the instruction accesses a configuration state register, in which a portion of the configuration state register is in-memory and another portion of the configuration state register is in-processor;
- and
- performing processing associated with the configuration state register, the performing processing being based on a type of access and whether the portion or the other portion is being accessed, wherein the type of access comprises a move to configuration state register, and wherein the performing processing comprises:
- generating a first set of internal operations based on the portion of the configuration state register that is in-memory;
- generating a second set of internal operations based on the other portion of the configuration state register that is in-processor;
- and
- executing at least one of the first set of internal operations and the second set of internal operations.
