19:46 <mwk> hey, has anyone here managed to install the vivado 2019.2 -> 2019.2.1 update? I downloaded the thing but "tar xf" is failing on the file

19:49 <mwk> gzip crc error

19:49 <mwk> I downloaded the file twice, fails with the exact same error, wondering if the server got hit by a bitflip or what

19:51 solo1 has quit [Ping timeout: 264 seconds]

19:53 <etrig> mwk: I don't remember having any trouble

19:55 <mwk> ....

19:55 <mwk> can I please get a Xilinx download server that does not suck

19:58 * mwk ponders how to obtain a working copy of that file

19:59 <etrig> I'm transferring my copy somewhere, but it might take a while :/

20:00 <etrig> oh, the situation is even worse: https://forums.xilinx.com/t5/Installation-and-Licensing/Vivado-2019-2-1-update-failure-on-a-working-Vivado-2019-2/m-p/1067731

20:01 <mwk> oh wonderful

20:01 <mwk> but that's not it, I just got served an obviosly-broken tarball

20:02 <etrig> just hopefully once you do finally get this it will actually apply to to the 2019.2 you have installed

20:04 <mwk> right...

20:28 <q3k> mwk, etrig: you should binary search for the bitflip

20:29 <mwk> q3k: right

20:29 <mwk> is there some easy way to do that?

20:30 <mwk> I'm thinking of just setting up an rsync server and letting it deal with that...

20:30 <etrig> split command and take sum of each chunk?

20:30 <q3k> not that i'm aware of, i'd write a shitty python script for that

20:30 <q3k> yeah

20:31 <sorear> if you have both files, cmp file1 file2

20:31 <q3k> they don't, that's the point

20:31 <sorear> if you have only the sha for the good file, there's no "binary search" option, I think all options are O(N^2)

20:31 <mwk> if I had the correct file, I'd just fix my own with "rm"

20:31 <etrig> :)

20:32 <sorear> flip a bit, hash the whole file, repeat (you can save half the work using common prefixes, but there's no corresponding suffix property0

20:32 solo1 has quit [Ping timeout: 250 seconds]

20:32 <etrig> mwk: first things first, is it 9691907164 bytes?

20:32 <mwk> 9691907164 yes

20:33 solo1 has joined ##openfpga

20:34 <sorear> reminder you can do rsync over ssh if both sides have rsync installed

20:35 <mwk> I'm behind multiple NATs...

20:54 <mwk> q3k: https://twitter.com/mwk4/status/1240018236923621378 success :)

20:55 <q3k> did you binary diff them?

20:56 <mwk> not yet

20:56 <mwk> got a recommended tool?

20:56 <q3k> uh xxd | diff -u

20:56 <q3k> that's what I've done for years

20:56 <q3k> and i'm not happy to admit it

20:57 <etrig> I like radiff2 from radare2

20:57 <mwk> the files are uhhh kind of large

20:58 <mwk> hm, wait, I'll just xxd the differing chunks

21:00 <mwk> huh wtf

21:00 <mwk> there are actually... lots of bitflips

21:00 <mwk> what the fuck happened

21:06 <q3k> but yeah wierd

21:06 <q3k> *weird

21:06 <etrig> do you have radiff2? the output is much more concise

21:06 <mwk> no...t yet

21:35 <lambda> so bit 0 and 2 are flipped seemingly at random (at least I can't make out an obvious pattern). oh well, happens to the best of us ;)

21:35 <mwk> but only in every 8th byte

21:36 <lambda> oh, right, that too

21:37 <mwk> also, </3 radiff2

21:38 <mwk> when I try to diff the fill tar.gz (and not the 37MB fixed chunk we transferred), it loads both files into memory and blows up with OOM

21:38 <mwk> *full tar.gz

21:39 <daveshah> Someone send Xilinx some new DRAM :)

21:39 solo1 has quit [Ping timeout: 264 seconds]

21:40 <lambda> maybe even ECC this time

21:40 <sorear> were the errors localized to a single 37MB chunk?

21:40 <etrig> mwk: oops, sorry

21:40 <mwk> sorear: even smaller

21:40 <etrig> mmap is hard I guess

21:40 solo1 has joined ##openfpga

21:40 <mwk> 37MB is just the point where we stopped binsearching and decided to just transfer the thing

21:41 <lambda> the diff spans across 32kB

21:52 <mwk> I would like to apologise to the xilinx download servers

21:52 <mwk> every time I run sha256sum on the (broken) file on my machine, I get a different result

21:52 <mwk> guess my RAM is fucked

21:53 <mwk> that, or SSD

21:53 <sorear> uh

21:54 <sorear> is the file larger than your RAM?

21:54 <mwk> it's not

21:54 <mwk> but it's larger than RAM available for caches

21:54 <sorear> what part of your ram is not so available?

21:55 solo1 has quit [Ping timeout: 250 seconds]

21:55 <mwk> the part that contains open chromium tabs and shit

21:56 <sorear> no swap?

22:58 * azonenberg appears in a puff of smoke

22:59 <azonenberg> mithro: you rang?

22:59 <azonenberg> (you do realize I *started* the channel, right? lol)

22:59 <mithro> Oh - I must be blind...

23:00 <mithro> azonenberg: I've started IRC channels that I eventually become no longer actively involved with....

23:00 <azonenberg> Fair point

23:01 <mithro> There was some discussion around how you debug high speed transceivers without also needing an expensive scope in the #symbiflow channel

23:01 <azonenberg> Define "debug": signal integrity or logic?

23:01 <azonenberg> or both

23:02 <mithro> azonenberg: both probably :-)

23:02 <azonenberg> Logic is best debugged with an fpga that has a transceiver on it... capture the data and debug in the slow domain

23:02 <azonenberg> SI normally means eye patterns, which is what FREESAMPLE is intended to do

23:03 <azonenberg> But i have too many projects and not enough time to work on all of them

23:03 <azonenberg> freesample is currently back burnered while i get the scope probes working
