Post by Dan BrowPost by Jon CortelyouSorry I used the wrong instruction set name. The Itanium CPUs are IA-64.
The new Intel CPU use AMD's x86-64 instruction set but I read that Linux
doesn't quite run on the new Intel CPUs yet.
I wouldn't say that Intel is using AMD's x86-64 instruction,
EM64T is AMD64, with a few minor variations (e.g., the missing NX bit,
and Intel is fixing that). Do you claim that this is a coincidence?
Do you think that Intel developed or co-developed AMD64? All
publically available information indicates that AMD developed AMD64 on
their own. About four years later Intel introduced EM64T, which is
remarkably similar. Do the math.
Post by Dan Browbut maybe
they got the idea that people want to see x86-64 before we go straight 64
Bit.
What do you mean with "straight 64bit"? AMD64's 64-bit mode is
straight 64-bit. As for IA-64, Intel obviously has given up the hope
that it will become mass-market, or they would not have introduced
EM64T (which put the final nail in the coffin of the
mass-marketability of IA-64).
Post by Dan BrowConsidering EM64T is just a extension to x86, Linux will run fine on
them. I may not be able to run x86-64 Linux yet, but will be able to
soon. I need do some reading on the patch set for x86-64 to see how far
they are.
It's up to you whether you can run x86-64 Linux yet. I have an Athlon
64 box running 64-bit Linux since last April or so. I know people who
run a Dual-Opteron box with 64-bit Linux since June 2003 or so.
If you want 64-bit Linux, certainly the selection of distributions is
much larger for x86-64 than for PPC64 (where the only options at the
moment are Gentoo and maybe Yellowdog).
