Abstract
Increasing the scope of local purges of structures associated with address translation. A hardware thread of a physical core of a machine configuration issues a purge request. A determination is made as to whether the purge request is a local request. Based on the purge request being a local request, entries of a structure associated with address translation are purged on at least multiple hardware threads of a set of hardware threads of the the machine configuration.
Claims20
A computer program product for facilitating processing in a computing environment, said computer program product comprising:
- a computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
- issuing, by a hardware thread of a physical core of a machine configuration, a purge request;
- determining whether the purge request is a local request;
- and
- purging, based on the purge request being a local request, one or more entries of a structure associated with address translation on at least multiple hardware threads of a set of hardware threads of the machine configuration.
A computer system for facilitating processing in a computing environment, said computer system comprising:
- a memory;
- and
- a hardware thread in communication with the memory, wherein the computer system is configured to perform a method, said method comprising:
- issuing, by the hardware thread of a physical core of a machine configuration, a purge request;
- determining whether the purge request is a local request;
- and
- purging, based on the purge request being a local request, one or more entries of a structure associated with address translation on at least multiple hardware threads of a set of hardware threads of the machine configuration.
A computer-implemented method of facilitating processing in a computing environment, said computer-implemented method comprising:
- issuing, by a physical thread of a physical core of a machine configuration, a purge request;
- determining whether the purge request is a local request;
- and
- purging, based on the purge request being a local request, one or more entries of a structure associated with address translation on at least multiple hardware threads of a set of hardware threads of the machine configuration.
