Yes, cpu_relax on s390 calls diagnose 44. Diagnose 44 translates to yield on z/VM and LPAR. Guessing from the number of the diagnose, I think it was used on z/VM for timeslice yielding long before Linux came to s390. _______________________________________________ Virtualization mailing list [email protected] https://lists.linux-foundation.org/mailman/listinfo/virtualization
