Monitoring expn64v2gcm work can be done via performance counters – look for metrics like expn_stalls, gcm_mul_cycles, unaligned_aborts.
While the exact naming depends on the repository, a reasonable breakdown is: expn64v2gcm work
So the tool runs a known-answer test or a throughput benchmark for AES-GCM, using pre-expanded keys and a version-2 internal engine. Monitoring expn64v2gcm work can be done via performance
The suffix gcm is the most significant part of this string. It almost certainly refers to AES-GCM, the gold standard for authenticated encryption. While the exact naming depends on the repository,
