diana_coman: BingoBoingo, thanks! confirmed back on + 1 fg available; unfortunately the simple test from smg_rsa (./tests 11 11 ) still hangs
diana_coman: I start suspecting it's maybe something to do with short+frequent reads as weirdly enough tests that read 4096 bytes seem... fine
diana_coman: well, uhm, scratch that, I just got one of those stuck too, lol; it took longer to get stuck, nothing else
diana_coman: aha; good to know at least it's not *just* that machine; might be worth to try replicating the dd hang as well , although by now I expect it will happen
diana_coman: machine with 2 fgs; reboot without init of any fgs; stty on only one fg; dd on that fg
diana_coman: dd seems to be more resilient but I suspect it's mainly because it's not that sort of little&frequent
diana_coman: i.e. if you run the eucrypt tests 0 or 1 that read more they tend to take longer to get to the hang (although they still do eventually)
diana_coman: fwiw same tests of eucrypt ran perfectly fine on all machines I have around here with fgs
diana_coman: anyways, if you find something the matter specifically with eucrypt code, I'd be quite happy really since it's easiest to fix tbh
diana_coman: hm, I usually get that above 7, closer to 8
diana_coman: anyways, dd hangs *sometimes*, harder to pin down ; ftr I DID go and read the dd code too but I can't say I'm any wiser as to why/how it is more resilient
diana_coman: hence my diana_coman> dd seems to be more resilient but I suspect it's mainly because it's not that sort of little&frequent
diana_coman: but a. WHY don't I have same trouble on any of the machines here b. WHY does it hang anyway c. wtf do I do
diana_coman: <asciilifeform> i suspect an oddity with the linux tty subsystem. the Right Thing solution would be to find it. the alternative, ugly solution, is 1) 512 byte buffered reads 2) with timeout . -> this is pretty much my current understanding as well
diana_coman: but I'm not comfortable with not knowing wtf in there because it has the potential to blow up very nastily indeed
diana_coman: fwiw eucrypt always gets stuck on the actual "read("
diana_coman: I'm going to dig around a bit more too to see if I can find any more clues of sorts
diana_coman: but yes, this is certainly not going to get solved in 1-2 days by the looks of it
diana_coman: myeah, as battlefield solution that might be the direction to take
Mocky: whoa, haven't seen that trilema.com header before
diana_coman: asciilifeform, ah,ah, the "modprobe -r " lulz, yes

mod6: guy says '<douchebag> can I be upped? I have some productive things to say' in PM, and I think "hmm. alright"
diana_coman: asciilifeform, I certainly say the last line, don't recall the first 2 but I might have missed them
mod6: it never fails. answering the door just doesn't work out too well for ole mod6
mod6: i should have just ignored. typically I do.
mod6: thought he might wanna talk about his rockchip, so was willing to give him the chance.
mod6: shit on the rug in the foyer.
diana_coman: mod6, I'd say don't worry about it; as a rule though productive people do stuff, not as if they need to "say" productively things
diana_coman: asciilifeform, I get as I recalled this "[63939.499700] pl2303 ttyUSB0: usb_serial_generic_read_bulk_callback - urb stopped: -32" but I don't see the others, hmm
diana_coman: that one I got even 8 times in a row there
diana_coman: ah, that might explain why I haven't yet noticed it
mircea_popescu: modprobe -r option << does ditching the "option" bs do anything ?
mircea_popescu: seems like a fine candidate for cuntoo banlist, if so.
mircea_popescu: as in, "i checked, we don't have" or as in "we couldn't possibly have something this fucking stupid o oops there it is how the hell did it sneak in"
mircea_popescu: this is looking more and more like we're going to have to write a pl replacement does it
mircea_popescu: still tbh i'm kinda pleased with how this ratchet works. mystery meat in fg-machine interaction had to await s.mg to be found. item's been out what, years, undergone all sorta testing...
mircea_popescu: not like we use usb for anything else anyway, so this may well work ad interim.
mircea_popescu: asciilifeform is there some way to connect as a tty bypass the usb altogether ? i really dun wanna include usb if can be helped.
a111: Logged on 2014-02-21 03:28 asciilifeform: usb is a highly-stateful protocol with a book-length standard
diana_coman: oh hey, asciilifeform that cure seems to work
diana_coman: so basically that's not for "if more than 2" but rather "always do it"
diana_coman: for future ref: echo first barfed with "invalid argument" ; it turns out it was appending a newline so it had to be "echo -n portnumber > ..."
diana_coman: makes sense; how do I do that best on gentoo? still line in /boot/cmdline.txt ?
BingoBoingo: asciilifeform: The other fishwrap refused to archived cleanly. Failed with a generic "content not available in your region" error page being archived instead.
diana_coman: after reading around on this mess with the usb speeds, the summary + questions would be: 1. the dwc_otg seems actually specific to raspberry pi so I don't see how it's directly useful atm; am I missing something? 2. the manual/runtime pill so far relies on the companion mechanism to force a USB port down from "high speed" to "full speed" so basically from ehci to uhci/ohci; wouldn't it make more sense to blacklist ehci, xhci and whatever
diana_coman: other "improved" xxxxhci and stick with uhci/ohci?
diana_coman: trinque, esp re why ehci if you can shed some light ^
diana_coman: I'm actively looking for any reason why xhci should be allowed in
diana_coman: well yes, and 10 or whatever they come up with next
diana_coman: so hm, on rockchip then FG are actually usable only with manual downgrade of usb port ?
diana_coman: ah, built-in ttl serialports sounds good, yes; re problem dun seem to exist, mhm, I'd rather expect it would pop up sooner or later if used intensively in this little&frequent style
diana_coman: and yes, otherwise I was thinking that a script can't be all that difficult to write for it too
diana_coman: but now I admit I got angry with ehci after all of today's barfing on the topic
a111: Logged on 2018-08-01 16:03 asciilifeform: 'After much researching it seems this is NOT a driver bug but a CHANGE in the kernel Serial API semantics. What has happened is that the API now blocks when a Serial device is not indicating it is ready. This included 'open' on a serial device which now can block. Since lots of RS232 serial devices do not bother with any control signals such as DCD (data carrier detect) they never indicate they are ready and open blocks. This is the
a111: Logged on 2018-08-01 16:08 asciilifeform: 2 possible tacks -- 1) kill, with flamethrower, 'new api' 2) FG opened once per machine boot and left running into buffer
mircea_popescu: there is no such thing as data that is all three of 1) random ; 2) useful and 3) buffered.
a111: Logged on 2018-08-01 01:52 asciilifeform could not muster the fuck-giving to read the payload, has nfi what the thing wants
mircea_popescu: right. and i didn't say anything about this then, either. also not :)
a111: Logged on 2018-08-01 21:33 asciilifeform: building a kernel without xhci would almost certainly do the job tho
mircea_popescu: yes, you miss out on downloading sony camera contents in such a manner as the "your media contains pictures!!!" popup can shoot "usefully fast". this is not a permitted usecase anyway.
mircea_popescu: losers shouldn't evne have cameras in the first place.
a111: Logged on 2018-08-01 21:36 asciilifeform: ( i can't afford it on dulap, because it also doubles as reimaging station for rockchippen , but s.mg prolly can safely say goodbye to usb3 )
mircea_popescu: but in any case usb-+ should not be on mainline kernel. let he who runs rockchip farm patch in the ugly.
mircea_popescu: asciilifeform could you make it a board ? use the agpx connector lol
mircea_popescu: yeah, ye olde boards weren't unusable enough, had to get rid of amirite.
mircea_popescu: ftr, i still have boards running my amds with proper isa cards...
mircea_popescu: you know, i'm tempted to put "must have 4x isa" on the reqs list for tmsr mobo ANYWAY.
mircea_popescu: (if the putative fast oscilloscope ever got interfaced with killer micro box, it'd be through isa also, i'm sure.)
mod6: BingoBoingo: feel free to wipe mats' rockchip when you have a spare moment.
mod6: I don't have information on which letter assignment is which.
mod6: ben_vulpes: can you send me this mapping if you have it?
mod6: All I know is that mats has number '196'.
BingoBoingo: Aite, alf should be able to confirm when he gets back from tea
mod6: cool. the '196' number is what I received from ben in that latest document that I marked up.
mircea_popescu: you know, all these "Random names" have a distinct handmade flavour.
BingoBoingo: Well, that's why they call the beast "Dirty Randy"
BingoBoingo: Whitened and bleached the random to the point the sweat stains leaked a very pattered yellowing
BingoBoingo: Aite, I'll walk over and stretch the legs now.
mircea_popescu: but it wouldn't surprise me if it were lusers, which is close enough.
mircea_popescu: asciilifeform apparently they're all domestic routers.
