nikolapdp has joined #osdev
<nikolapdp>
well now it's working
<nikolapdp>
and to get it working i had to add a line to netstart which initialized the inteface
<nikolapdp>
for some reason
<nikolapdp>
didn't have to do it before i changed the bus/network card
<kof673>
what does the c compiler look like there? is it c89-ish? k&r only?
<nikolapdp>
pre ansi
<kof673>
does it have struct surely?

<azonenberg>
So I'm trying to design a consistency self-test for a key-value store. Trying to figure out what makes sense for the actual test algorithm
<azonenberg>
Specifically, the goal is to ensure that if I abort midway through a write, I won't ever get corrupted or invalid data back
<azonenberg>
i always get atomically the old or new value
<azonenberg>
So i need to design a sequence of (name, value) tuples that I can write to the KVS repeatedly such that it's possible to determine, given only a snapshot of the KVS, whether any corruption has occurred
<azonenberg>
My initial thought is to have two objects A and B that I initially write with the values 0 and 1 respectively, then i ping-pong increment each one by 2
<azonenberg>
so you have 0/1 then 2/1 then 2/3 then 4/3
<azonenberg>
then repeat the value a few times within the object to pad it out to a larger size so 4 would actually be say 0x00000004 00000004 00000004 00000004
<Mondenkind>
azonenberg: maybe do a simple perfect hash (sth like the murmurhash finaliser should be fine) to get a lil more entropy in there

nikolar: oh woot. what was the key thing that had it working?
<nikolar>
Well first I switched to unibus
<nikolar>
And 11/70 like you suggested
<nikolar>
Set up dz0
<nikolar>
Also realized that you need to update netnix along with unix
<nikolar>
I kind of forgot that it's not a separate kernel kek
<geist>
yah
<geist>
yeah it's sort of like process 1 i guess. it must do some sort of thunking style context switch between it
<nikolar>
Another thing is that I had to switch to a unibus Ethernet card
<nikolar>
Which didn't just work (tm)
<nikolar>
I could ping withing my lan but not outside (ie internet)
<nikolar>
So I added the ifconfig line to setup the interface to /etc/netstart
<nikolar>
And that finally got it to work
<nikolar>
Though when I am not throttled, I get the `coremap: overflow, lost 67 clicks at 016556` type of lines all the time
<geist>
ah yeah. that's right. been a while since i configured mine
<nikolar>
Presumably related to the serial speed
<nikolar>
When I throttled, those seem to go away
<geist>
which network eth did you end up using?
<nikolar>
And I couldn't get vmstat and iostat to work :(
<geist>
i'm using qe0 on my physical one
<nikolar>
it's de0
<nikolar>
qe0 just worked out of the box
<geist>
but it's qbus, i guess
<nikolar>
After setting the hostname and default route and network mask in the netstart
<nikolar>
It is, yeah
<nikolar>
I might need to recompile vmstat and iostat for them to work with the current kernel, I'm not sure about that
<nikolar>
They don't work after enabling the option that specifically references them
<kazinsal>
ah for the days when networking was "simple" and you didn't have to worry about a bajillion threats. just give your pdp-11 an internet address and start calling up other institutes
<nikolar>
Kek yeah
<kazinsal>
sometimes I wish I were doing the job I do now, but 40 years ago
<geist>
yeah i dunno. my vmstat/iostat work, but i also updated mine to version 481. what version are you on?
<geist>
read /VERSION
<nikolar>
Lol yeah kind of feel the same
<nikolar>
It's unpatched, or at least should be
<nikolar>
I'll check in a bit, not at my computer right now
<nikolar>
I'm just curious why qe0 worked without adding ifconfig to netstart but de0 didn't

i was being silly

i was overwriting the generated makefile lol

<mcrod>
newlib sucks
<mcrod>
jesus fucking christ
<nikolapdp>
lol
<mcrod>
for some strange reason it’s insisting on using a coprocessor instruction on my cortex-m0+ board
<zid>
that's the mcrod we know and love <3
<mcrod>
no matter what’s going on
<zid>
rust also insists on using sse on x86
<mcrod>
i can’t believe ARM shipped this
<nikolapdp>
kek
<mcrod>
i call _start
<mcrod>
and it dies on _fini which is to handle destructors
<mcrod>
and the first instruction isn’t valid for m0+
<mcrod>
i have to now compile my own newlib to resolve this
<nikolapdp>
to be honest, that doesn't dound like a newlib issue
<mcrod>
you say that
<mcrod>
but I’ve pumped -mthumb and -mcpu=cortex-m0plus everywhere
<mcrod>
and STILL it’s giving me shit
<zid>
linker script filling .fini with dross?
<mcrod>
what’s dross
<zid>
an english word meaning.. crap
<zid>
but aren't you supposed to erm
<zid>
treat .fini as an array and call each pointer
<zid>
not run .fini
<mcrod>
ask newlib
<zid>
but you're doing the former
<zid>
you said you called
<mcrod>
my only crime is calling _start();
<mcrod>
that calls __libc_init_array()(
<mcrod>
phone sucks
<zid>
nikolapdp: good news, once I finished putting the 800GB of serbian goat porn onto that hdd my mouse started working again
<mcrod>
you’re supposed to call _start()
<nikolapdp>
oh nice
<nikolapdp>
some string emf
<zid>
I assume it must be a shitty usb3 cable
<nikolapdp>
eh could be
<zid>
cus the hdd itself should be just a standard wd inside a plastic tub
<zid>
and standard wds don't have bad EMF issues
gog has joined #osdev
<zid>
so I guess the usb3 cable is just completely lacking the tinfoil shield
<nikolapdp>
does usb3 even run at speeds that cause emf issues at those frequenceis
<nikolapdp>
i guess there's always ripple in the signal
<zid>
look at the transfer speed
<zid>
it's in the gigabits range
<zid>
so it nicely intefers with wifi
<nikolapdp>
nice
<nikolapdp>
i forgor what speeds usb3 runs at
<nikolapdp>
or whatever they are calling it these days
<zid>
pa5bit
<zid>
5gbit
<zid>
exactly 5ghz wifi :P
<nikolapdp>
kek
<zid>
or a very strong 2nd harmonic of 2.4
<nikolapdp>
yeah that too would do it
<nikolapdp>
but for some reason, i remember that usb2 is 480mbit/s lol
