https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=253505 Jason A. Harmening <jah@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jah@FreeBSD.org --- Comment #2 from Jason A. Harmening <jah@FreeBSD.org> --- dmesg shows GELI advertising "accelerated software". I think this is expected. aesni doesn't advertise CRYPTOCAP_F_HARDWARE. From aesni_attach(): sc->cid = crypto_get_driverid(dev, sizeof(struct aesni_session), CRYPTOCAP_F_SOFTWARE | CRYPTOCAP_F_SYNC | CRYPTOCAP_F_ACCEL_SOFTWARE); Since AES-NI uses special-purpose instructions on the local CPU, I think we would consider it "accelerated software": it's not a pure software scheme like cryptosoft, but neither is it a separate hardware offload engine. If GELI were using cryptosoft instead, you'd just see "software" instead of "accelerated software" in dmesg. You can run 'show crypto' in ddb to double-check. -- You are receiving this mail because: You are the assignee for the bug.help
