摘要
A method, system, and computer program product for target computer processor unit (CPU) determination during cache injection using input/output (I/O) adapter resources are provided. The method includes storing locations of cache lines for pinned or affinity scheduled processes in a table on an input/output (I/O) adapter. The method also includes setting a cache injection hint in an input/output (I/O) transaction when an address in the I/O transaction is found in the table. The cache injection hint is set for performing direct cache injection. The method further includes entering a central processing unit (CPU) identifier and cache type in the I/O transaction, and updating a cache by injecting data values of the I/O transaction into the cache as determined by the CPU identifier and the cache type associated with the address in the table.
