Hi, My reading of atomic(9) implies that the atomic_testandset_* family of functions should be present on the arm architecture, however I don't see any evidence of it in any of the expected locations, ./sys/arm/include/atomic-v4.h ./sys/arm/include/atomic-v6.h ./sys/arm/include/atomic.h Is there some impediment within the architecture which doesn't make that semantic possible or is it just that there is no in-tree consumer yet? Any thoughts on this matter would be appreciated, or better yet a possible implementation - sadly for me assembly is not my strength.
