snsabot: Logged on 2020-08-20 19:30:21 asciilifeform: there is presently no 100%-documented homogeneous fpga on market. and, for fundamental reasons, aint likely to be, 100% of fpga vendors live from the 'rent out the right to use our built-in NIC' and similar scamola
gregorynyssa: problem is, no one sells densely etched LUTs as a generic commodity. everyone (Xilinx, Intel...) sells "solutions," or worse, "experiences," but I still see two narrow avenues out of this mess:
gregorynyssa: (1) some universities have small VLSI facilities. see if you can get a deal to use those. (2) start your own coarse-grained fabrication-facility. 100-500 nm is fine for the next ten years of Lisp Machine revival. I don't think < 100 nm is necessary. presumably the costs of building such a facility have decreased compared to the 1980s.
gregorynyssa: basically, the Armadillo Aerospace of fabrication.
gregorynyssa: nuclear engineering students today know how to rebuild 1940s atomic bombs at a fraction of what it had cost that era. someone should likewise re-trace the machinery of 1985 from first principles.
asciilifeform: http://logs.nosuchlabs.com/log/asciilifeform/2020-08-22#1020093 << a fpga was originally ('80s) precisely 'bag of LUTs.' the 'let's include 9000 undocumented periphs and license out the closed turds to drive'em' biz model came in '90s.

asciilifeform: re: 'with ttl and pcb' -- ever seen the machines that were built this way ? y'know, the 'five refrigerator's worth of comp , + five actual refrigerators for cooling, tops out at 1MHz' items.

asciilifeform: closest i've come so far is some chinese uni who actually wrote to asciilifeform and offered use of their fab. but unsurprisingly wanted ~50k usd ~per run~ in compensation. folx dun work for phree, not even in china.
asciilifeform: re (2) , 'start your own coarse-grained fabrication-facility' -- right after i open own spaceport, lol
asciilifeform: 'presumably the costs of building such a facility have decreased compared to the 1980s' -- ~increased~.
asciilifeform: substantially increased.
asciilifeform: because of monopolization. at one time there were thousand+ semiconductor fabs on planet3. then, hundreds. now, perhaps two dozen.

gregorynyssa: http://logs.nosuchlabs.com/log/asciilifeform/2020-08-22#1020099 << makes sense. I suspected as much, and I keep coming back to the 1990s as the decade when the development of computing went terribly wrong.

gregorynyssa: asciilifeform: suppose we don't use any FPGA. suppose you directly owned a fabrication-facility and could perform your own runs on whim. how low does the process-width have to be, for it to be worth your time?
gregorynyssa: (ie. for your project to succeed?)
gregorynyssa: IIRC the 80386 had a process-width of 1,000 nm.
asciilifeform: gregorynyssa: for that matter, bolix's 'ivory' was a 2uM item.
asciilifeform: http://logs.nosuchlabs.com/log/asciilifeform/2020-08-22#1020128 << there's a kind of 'vicious cycle' there -- anyffin above 30-40MHz or so demands short, straight paths, and fast (ideally vlsi) logic on other end.

asciilifeform: si fabs, whether in '70s, '80s, '90s, or today, were serious capital goods that had to be occupied w/ production of salable products 24/7 to make 'in the black'.
asciilifeform: smbx for instance ultimately failed to pay back the investment in baking 'ivory'.
asciilifeform: ( and they did, incidentally, have the good sense ~not~ to build own fab -- they had hp do it. and these were folx who blew own glass for crt's, as no off-shelf crt in 1980 would do 'supervga' res... )
trinque: any attempt to fab own CPUs would have to step through many other, simpler devices on the way, or yes, pull in a huge investment.
trinque: (with little chance of repayment)
asciilifeform: trinque: aha. asciilifeform wanted to give a sketch ftr of just how 'megalomania' intrinsically in the idea of 'bake own fab'
asciilifeform: it aint necessarily obvious to the innocent
asciilifeform: it's an idea roughly on the scale of 'build own 10GW nuke power station'. and consider fact that e.g. su had working native designs for the latter -- but afaik never built ic fab w/ purely native tech, all contained smuggled-in heavy gear
asciilifeform: even today, infamous 'elbrus' is fabbed in tw, at tmsc co.
asciilifeform: ( incidentally, the ru design bureau that baked 'elbrus' did not even attempt to have the supporting periphs -- nic, vga, etc. fabbed . instead off-shelf. they figures, prolly correctly, that no amt of $ would suffice... )
asciilifeform: * figured
asciilifeform: 'holy grail' ultimate pill here would obviously be 'desktop fab'. but afaik currently is not even in realm of 'science fiction', but rather lsd fantasy, sadly.
snsabot: (trilema) 2015-07-26 asciilifeform: folks like to talk about 'printed' this and that, but the actual hard data on the ground are considerably more optimistic for classical problems like 'lead to gold', 'elixir of immortality', and 'energy too cheap to meter' than for desktop chip-fab.
asciilifeform: imho the standard methods for ic fab are a political dead end .

snsabot: bvt last seen in #ossasepia on 2020-05-25 05:15:47: if i liked that code, i would have just released the vpatch immediately with performance benchmark, so i agree with 'case against'. i will look into improving the error reporting code -- this should be possible (with slightly more code in v.sh), though the precise loop analysis would take approximately the same amount of ada code as went into that experimental vpatch.

trinque is over here grunting over the perl build for why it's shitting "pod" files into the root dir.
trinque: after that it's about time to cut a genesis, I think.
trinque: I'm curious what those present think in terms of a bootloader; I touched on this in the OS series before.
trinque: lilo's small, but incurs its own assembler (bin86)
trinque: extlinux looks like it *might* be small if it can be severed from the sprawling shitheap of syslinux (which at first pass demanded a python and other nonsense)
trinque: grub eh, maybe an old one, but that's a tenuous maybe
trinque: bootloader ftr is not needed for genesis. what I've got is plenty useful by itself as gcc-sturbator.
asciilifeform: trinque: sometimes bootloader is not even needed at all -- e.g. on apu1 & other amd g-series boxen, can bake kernel straight into bios
asciilifeform: so imho it is a secondary item, and asciilifeform for one would not object if it were genesis'd separately
asciilifeform: the 1 problem with this is that linux kernel is 'pathologically lazy', in fact does not initialize irons properly, offloading good portion of this work to the loader
asciilifeform: imho this oughta be fixed, at some pt, ~in the kernel~. really there is no reason why linux's bootloader needs to be any larger than my illustrative one.

trinque: at least automake wants perl, and there were several others.
asciilifeform: aah
trinque: while automake is still used by gcc, gotta have perl, sadly.
trinque: I don't intend to genesis something that "so long as you don't blow on it too hard, don't need x y z"
asciilifeform doesn't disagree
trinque: ftr gprbuild seems a good candidate for blowing it all away.
trinque: (perl, m4, autoconf, automake, libtool)
trinque: the parts I've contributed so far only want posix shell
asciilifeform: trinque: gprbuild i can see replacing standard 'gnumake', but it doesn't (by design) have generalized text-munging, so prolly not m4 et al, unless somehow the 'need' for munging can be eliminated
trinque: I'm pointing to eliminating the need, yes.
asciilifeform: aha
asciilifeform: observe that the folx who baked ada, apparently agreed w/ asciilifeform's take on 'ifdefism'
asciilifeform: there's 0 support for it in the lang, or even in 'gprbuild'
trinque: indeed, and god help me if I start caring about quirks of make on solaris, or wtf.
asciilifeform can even see the pov of folx who want different build paths for $proggy on x64, arm, arm64, etc. but ada committee apparently did not.
asciilifeform: 'portabilityism' is a traditional concern for unix folx, but evidently not for the people for whom 'there's 1 rad-hard 386, circa 1990, and guess what, this satellite WILL use it'
asciilifeform: the interesting bit is that ada has features like hard-bitness constraints for structures, native support for endianisms (including multiple endianisms ~inside one data structure~) and similar support for troo portability afaik absent ~anywhere~ else .
asciilifeform: but the way i understand it, the above were included simply from pov of 'a correctly-writen program MUST maximally specify its semantics', rather than from 'what if someone wants to build this for a vax suddenly'.
