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? [unhandled content-type:application/pgp-signature] | |
