As an example, my Atom N270 reports: flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca = cmov pat b19 b21 mmxext mmx fxsr xmm sse2 b27 b28 b29 3dnow Whereas dmesg reports: Features=3D0xbfe9fbff Features2=3D0x40c39d> AMD Features2=3D0x1 Is there a particular reason why the flags output isn't complete? As an example, I recently tried to run a binary Sage package (www.sagemath.org) in FreeBSD -current. During startup, it verifies that the target CPU supports the instructions used and, on my Atom, complained that 'ssse3', 'pni' and 'sse' are missing - whilst they are missing from cpuinfo flags, they are present in the Atom. --=20 Peter Jeremy --b5gNqxB1S1yM7hjW Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.12 (FreeBSD) iEYEARECAAYFAkpX4hIACgkQ/opHv/APuIf8JwCbBNSaXvG3+Mlc4/TEcZFL32BC IXkAn1//rh/6mioBPODrDBQKrK8AdcYU =sAAc -----END PGP SIGNATURE----- --b5gNqxB1S1yM7hjW--
