OK, it's true that Linux has some brilliant programmers available that could work full-tilt on putting together a Linux distribution in record time. But the SPARC port is not the best basis of comparison with the Merced:
1) The SPARC architecture has been around for quite some time, so many people have had a chance to program in SPARC assembly language.
2) The machines are quite common by now, specially in academic settings. It's quite easy to find a SPARC machine where one can get a user account.
3) GCC has been ported to the SPARC for quite some time.
Merced does not fulfill any of these conditions.
Now about the Non Disclosure Agreement (NDA) terms that Intel uses, an example is the 4Mb paging extensions, which initially had a 15-year NDA! You can read all about it in Robert Collins' site (http://www.x86.org).
By 2000, we could have the following processor alternatives for further Linux development:
- SPARC derivatives. Good: they have been available for a long time. Bad: expensive. Unless somebody comes out with a cheap PCI SPARC motherboard. - IBM Power PC derivatives. Good: ubiquitous. Bad: Apple is disallowing clone manufacturers. Again, unless somebody comes out with a cheap PCI Power motherboard; there is a petition around the Net for this (see the link on the LDP site). - IA-64. (Discussed already). - Alpha. Good: Linux-ready. Alpha machines are _almost_ affordable now. Bad: future uncertain after buyout by Intel. - MIPS. Good: partial Linux port available. Bad: tell me where I can buy a MIPS PCI motherboard, or even a complete CPU under $10K? - x86 derivatives. Good: at least we can choose from various manufacturers, and mail-order a new motherboard to upgrade our Linux boxes from time to time. Bad: old architecture, outdated instruction set!
No CPU seems to combine affordability, performance and sufficient information availability. This is basically what worries me over the long term.
Salutaciones cordiales de Francia,
