The T2 and T3 has a separate crypto unit, but not supported here.=20 Support was removed from the kernel in 6.14. Haven't tested it, as I don't have the hardware. Also worth noting, it's only used when the firmware lists the machine description's hwcap-list and the CFR has its bit set.=20 I have no idea about Fujitsu's SPARC64 X family. --=-Z6bEZk1QJDhfraz15yO+ Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTK1ph9OaYoND1R57zoeAEuJe36VgUCarzTSQAKCRDoeAEuJe36 VnZLAP4ueNBjD5U8fxj10uk6oB1o72itnfwX6IzaTigKjsGFTAEA6OVe+gd3KqtA fx3a2s3USut+VsyJZC0NGduYIKHlbg0= =ivE0 -----END PGP SIGNATURE----- --=-Z6bEZk1QJDhfraz15yO+--
