Same here - /proc/cpuinfo says: vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 Mobile CPU 1.60GHz Question for those more knowledgeable: Are there any known Pentium4 features enabled in the kernel with the PENTIUM4 options that simply Will Not Work on a 4M chipset (similar to a kernel built for a 586 not working on a 486), or are the differences limited to "sub-optimal performance" (for example, compiling with -mpentium4 results in code that runs but schedules less optimally)? If there are, they must be fairly obscure corner cases, since I haven't knowingly hit one in several months.. :) 2.7 timeframe - are there any added features of a P4 core we would *like* to exploit that aren't on a P4M? --==_Exmh_873559510P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQE/+HjncC3lWbTT17ARAkFkAJ9AsX5R/v6msInljHkPs0eTJ/EkRgCfUnzi E4ShLnhhTH+NZ7mbd5DjgY0= =lIZi -----END PGP SIGNATURE----- --==_Exmh_873559510P-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
