Description Ben Beasley 2021-08-17 13:54:50 UTC

Upstream uses architecture-specific assembly for the implementation of “spin_lock_pause()” in include/atomic_queue/defs.h. There are implementations for x86/x86_64 and ARM (32 and 64 bit).

An implementation for s390x is needed to support that architecture.

See https://bugzilla.redhat.com/show_bug.cgi?id=1988151 for a candidate and for discussion. The candidate presented there references the incompatibly-licensed Linux kernel, but the snippet itself is so trivial, and the available choices for a correct implementation so few, that it may not present copyright/license issues.

Comment 3 Ben Beasley 2021-10-20 18:06:40 UTC

I’m working with upstream to add support for s390x/ppc64le in https://github.com/max0x7ba/atomic_queue/issues/33. Initial support for these architectures is now in Rawhide.

The current support for these architectures assumes 64-byte cache lines, which is less than the actual value (128 bytes on ppc64le, 256 bytes on s390x). This can be expected to lead to less-than-optimal performance. Upstream is aware of the correct cache line sizes, but some other adjustments in the code will be required to support larger values. Once that settles, out, I plan to build updates for F35 and earlier stable releases, including EPEL8.
