mircea_popescu: nice alternative to the linux-on-amd freezeout
mircea_popescu: amd couldn't hire a new set.
asciilifeform: amd hired the designers away
mircea_popescu: unless amd fixes its shit
a111: Logged on 2017-02-23 03:55 mircea_popescu: anyway, the point in case block we were discussing yest. i timed it at 22 minutes on "reasonable" amd.

asciilifeform: http://developer.amd.com/tools-and-sdks/cpu-development/x86-open64-compiler-suite << still has (what purports to be) the circa-2013 tarball.
asciilifeform: my sageprobe setup (amd g-series mobo, probe, cables, lcd, keyboardmouse) fits in briefcase. and with plenty of room to spare (for, e.g., battery if i ever put one)
ben_vulpes: looking forward to the amd hike
a111: Logged on 2017-01-06 13:28 mircea_popescu: like what ? something like amd fx 9500 is, i bet, way ahead anything apple ever put in anything they made.

asciilifeform: 'This post has a lot of misunderstandings behind it. First off, the Intelligence Community does not need to force Intel to give up Manageability Engine keys (or AMD's PSP keys for that matter). Both the keys and the toolchain, as well as the source code are traded underground. I know that at least up to firmware version 8 is traded underground, and version 11 (the latest) is available without difficulty to people who know how to find
asciilifeform: or server variant: 'Talos™ Desktop Edition (TALP8D050) A complete Talos™ workstation with a CPU of your choice, 128 GB of DDR3 ECC RAM, an AMD Radeon RX 480 (8 GB VRAM) GPU, and two Western Digital WD40EFRX 4 TB SATA drives, all installed in a heavy-duty tower chassis. Comes pre-installed with Debian.'
asciilifeform: containing the glue logic b/w the amd debug bus and the arm micro.
jhvh1: asciilifeform: Socket 1207 Motherboard | eBay: <http://www.ebay.com/bhp/socket-1207-motherboard>; Socket F Computer Motherboard | eBay: <http://www.ebay.com/sch/Socket-F-Computer-Motherboard/1244/bn_651799/i.html>; Socket F Computer Motherboard for AMD | eBay: <http://www.ebay.com/sch/Socket-F-Computer-Motherboard-for-AMD/1244/bn_656720/i.html>
mircea_popescu: yeah amd went the way of gaddafi even as intel went the way of obama.
asciilifeform: (must point out, though, opteron was not a cheap-side chip, and the mobo that ate it -- also was not, was top-of-the-line in amd world)
mircea_popescu: i7 4870 was released mid 2014 ; the amd mid 2013 if memory serves.
mircea_popescu: the amd is about 6 months OLDER than your intel.
mircea_popescu: the amd has dd3 2133
mircea_popescu: so then. you probably need a dozen bridged crapples to touch the amd box.
asciilifeform: best amd box i have is a 2socket x 2393SE.
mircea_popescu: like what ? something like amd fx 9500 is, i bet, way ahead anything apple ever put in anything they made.
asciilifeform: (all of my full-sized mircea_popescu-style comps are 'bearded', this comes with using pre-obummer amd iron.)
asciilifeform: perhaps he got bored when he saw that phuctor didn't pop the amd keys...
asciilifeform: welcome, ben_vulpes , to the dour world of amd opteron et al, where 'working box is moarprecious than gold, because gold is merely an element in mendeleev table and you can always get more, but there will only get fewer boxes, and quickly'
asciilifeform: anyway there were two and afaik exactly two makers of pc-compatible boards with the last, magical, amd g-series, and shipped full schematics.
asciilifeform: walter: afaik the last chip that worked 100% correctly on 'coreboot' was amd G-series 'APU'.
asciilifeform: coreboot, last i saw, largely consists of some sad folks sitting and being sad, because it works on 0 cpus presently sold, and on account of quite deliberate sabotage by intel and amd.
asciilifeform: interestingly, unlike nvidia, amd published (what were nominally..) complete datashits for all of their gpu.
asciilifeform: and amd bakes magic key into mask rom.
asciilifeform: Framedragger: jurov posted a quite working one earlier, i used it for the amd keys recently
mircea_popescu: he certainly gets amd.com or w/e.
asciilifeform: it is already, consider, quite physically possible for some d00d to register here with the amd key (visible in phuctor)
asciilifeform: namely, the folks in physical possession of the magic keys for amd, intel, crapple, etc.
asciilifeform: i'm still waiting to see them lose something expensive, e.g., the intel/amd microcode booby.
asciilifeform: trinque: ditto the amd signing key from last month's thread.
kmalkki: apu2 (with AMD PSP) does respond properly to JTAG IDCODE
asciilifeform: ben_vulpes: i would not rule out the bootrom.bin being identical, or similar, to the one in the amd thread. and the linked author's refusal to share it is rank cowardice, must point out.
asciilifeform: ben_vulpes: only if that amd key phuctors. or the idiocy in subj thread is finessed in some other way.
asciilifeform: ftr, if the amd turd is anything like other recent similar, you will also need ion beam machine
mircea_popescu: asciilifeform incidentally, this would be great for reddit. "Hi. I live in <ZIP> and I need access to {list} instrument in order to explore the AMD chip so and so. Anyone know anyone ?"
a111: Logged on 2016-10-05 03:54 trinque: from now on I'm gonna have a pang of "OH SHIT, WAS IT THE AMD KEYS?!" every time there's a phuctor rss
trinque: from now on I'm gonna have a pang of "OH SHIT, WAS IT THE AMD KEYS?!" every time there's a phuctor rss
kmalkki: I guess you have heard how AMD SMU keys leaked out for previous gen?
asciilifeform: any idea how amd revokes ?
kmalkki: and then OEM can sign their firmware without bothering AMD for every build
kmalkki: the idea behind all this, is OEM can send their public key to AMD to be signed
kmalkki: same as before, but from 0x240 starts signature with RSA-SSA-SIGN with AMD's private key
asciilifeform: kmalkki: do you perchance know the format of the amd public keys seen here : http://btcbase.org/log/2016-10-04#1552732 ( from coreboot dist )☝︎
asciilifeform: but no, i don't have access to any amd members-only whatevers.
kmalkki: do you have access to AMD BKDG documents?
asciilifeform: mircea_popescu: kmalkki is an experimenter with sage/amd g-series/etc.
asciilifeform: default "3rdparty/blobs/southbridge/amd/kern/PSP/AmdPubKeyCZ.bin" if CPU_AMD_PI_00660F01
asciilifeform: default "3rdparty/blobs/southbridge/amd/avalon/PSP/AmdPubKey.bin" if CPU_AMD_PI_00730F01
asciilifeform: 'PSP: The Cortex A8 running trustzone firmware, implemented from family 15h model 60h (Carrizo) and family 16h model 30h (Mullins) and up. It is running Trustonic TEE OS licensed by AMD. PSP Boot ROM runs *before* x86 core. Then non-bootrom PSP parts are stored (zlib-compressed) in the main flash. Bypass mechanism available via strap pin, but dummy and AMD signed bypass binaries needs to be always run. It is expected that newer CPUs
asciilifeform: amd's shitball, as-released
asciilifeform: https://github.com/coreboot/blobs/tree/master/southbridge/amd/kern/PSP << lulzy, on subj.
asciilifeform: it also has a broad spectrum of short-term half-solutions (use minimal subset of the iron's functionality; stockpile old amd; etc)
asciilifeform: nobody knows what amd generated these with. could've been msword for all i know. could've been motherfucking quark express. but in any case all they published (WHEN they published anything) is pdf.
asciilifeform: trinque: http://support.amd.com/TechDocs/43009.pdf http://amd-dev.wpengine.netdna-cdn.com/wordpress/media/2012/10/43366_sb7xx_bdg_pub_1.00.pdf << amd sb700 chipset docs. (and no, they do not exist in any other format, nor will they)
asciilifeform: trinque: naturally the probe won't do anything useful without being connected to a powered amd mobo
asciilifeform: shinohai: the amd thing is for aficionados strictly
asciilifeform: !~later tell trinque i found another debuggable amd board, http://www.semiconductorstore.com/cart/pc/viewPrd.asp?idproduct=48155
asciilifeform: amd made its own debugger for its boards, i even have one here, but it has never been satisfactorily reverse-engineered, isn't gdb compatible. i have a brand-new one here, in its crate, waiting for its day.
asciilifeform: http://www.xbitlabs.com/images/news/2013-01/amd_gizmo_board.jpg << subj is in right hand, rear
asciilifeform: trinque: debugger attaches to 'amd hdt' connector, present on the board. there are landing pads for it on surprisingly many amd mobos
asciilifeform: incidentally, trinque, phf, et al : http://www.mcmelectronics.com/product/83-16358 << this here's the OTHER 'schematics published, amd g-series, sage plug' board. and this one has vga. and apparently is going out of print, being sold for half price in a few places.
asciilifeform: amd g-series with , iirc, gpl schematics.
asciilifeform: betcha there is even a magic bit in amd docs that'll force no-inst-fetch-out-of-l0.
asciilifeform: http://support.amd.com/TechDocs/42301_15h_Mod_00h-0Fh_BKDG.pdf << and before anyone asks, it is neither available in any other format, nor accurately convertible -- is sufficient illustration of my point. flip through it and weep.
asciilifeform: mircea_popescu: it is documented, and you won't like it at all, e.g., here -- http://developer.amd.com/resources/developer-guides-manuals
asciilifeform: cache, incidentally, is controllable at least on amd.
mircea_popescu: html5 had a fighting chance as "not just text" ; it lost. this shit is dumber still, with a larger ground to cover still, with less talent and intellectual capacity involved ; and with the corporate nonsense that formed the original impetuus, from apple "app store" to cisco via intel/amd fritzchips etc dying left and right. the bottom's already fell out of apple store, there's no revenue made, and all these idiots can go back
asciilifeform: lobbes: http://support.amd.com/TechDocs/52740_16h_Models_30h-3Fh_BKDG.pdf << section 2.14 is afaik the ONLY public doc on amd's fritzchip
a111: Logged on 2015-10-27 15:25 asciilifeform: there is literally 1 paragraph devoted to amd:
lobbes: asciilifeform: I've been searching logz for thread regarding modern AMD cpu being almost as subverted as Intel's. you wouldn't happen to have good reading on the subject handy, would you?
mircea_popescu: "if i let bill work remotely he might who knows, fuck his wife! whereas this amd is safe, it'll just sit there."
BingoBoingo: Well, stanley black and decker company has problems prolly, but... exist now as ghostly AMD to TTI's intel
asciilifeform: likewise the intel and amd boobytrap cores dun go away when we close eyes.
asciilifeform: http://seclists.org/oss-sec/2016/q1/450 << we luuuuuuv amd!111111
phf: http://www.anandtech.com/show/10268/china-calling-amd-forms-joint-venture-for-x86-server-socs-in-china
asciilifeform: it is not actually hard to massively improve on cadr, much of its gnarl was that it had to be made of 74xxx and of weird amd ALUs available at the time
BingoBoingo: The AMD E350 'Bobcat' is still frequently available, often soldered into MB
mircea_popescu: but yes, one thing the republic might consider is a stockpile of proper amd chips
mircea_popescu: anyway. yes amd gave us usable computers for a five-year plan longer than'd have been otherwise possible.
mircea_popescu: not to mention there's a whole colonization of amd in the arm space.
asciilifeform: but ftr i discussed the intel and amd 'palladium' engines in detail in the old logz.
mircea_popescu: so this is an absolute defense against any and all accusations of "computer crime" for as long as the hardware involved is post 2009 intel / 2013 amd.
asciilifeform: amd g-series.
assbot: Dell Poweredge 6950 AMD Opteron Socket F CPU Heatsink Y9115 | eBay ... ( http://bit.ly/1TQnaa8 )
kakobrekla: http://www.ebay.com.au/itm/Dell-PowerEdge-6950-AMD-Opteron-Socket-F-CPU-Heatsink-Y9115-/251322845713
asciilifeform: where do you see AMD F in these ?
danielpbarron: you linked some thing on ebay, has amd processer and ecc ram or whatever
mircea_popescu: http://qntra.net/2016/02/growing-bitcoin-game-hits-high-for-single-day-play-seconds/ << ftr item 7 in that footnote appears like an unreadable pile. amd is there a footnote 2 ? seems to go 1 and then 3.
asciilifeform: used at, e.g., amd, to prove the correctness of their alu.
mircea_popescu: it's feasible average consumer would prefer to watch visually upgraded angry birds on amd hardware to watching another talkshow.
mircea_popescu: i dunno how familiar you are with ipad/android on one hand, and steam and derivatives on the other ; but amd's ploy is plainly to make a hardware-sum-of-these.
asciilifeform: and b) would put amd on the leading edge of advanced usgtronics of the Fyootoor, at last
