<heat>
ok so what do you think of that codebase in general
<mjg>
so apart from the 1024 cpu luller
<mjg>
if you don't want to use hyperthreads, llvm will try to find out how many real cores you got
<mjg>
to that end it is going to parse /proc/cpuinfo :d
<heat>
hey at least it's not parsing /sys
<mjg>
which i'm confident defeats the point
<mjg>
heat: dtrace is code is classic solaris
<mjg>
heat: most notably in terms of lack of *actual* regard for multicore or numa
<heat>
but seriously WHAT SHALT I THINK OF DTRACE
<heat>
i remember you told me to use eBPF for Onyx and to not bother with dtrace
<mjg>
dtrace is adeadend, which is why
<mjg>

cuz bpftrace doesn't seem that widespread either
<heat>
m9 eBPF can't loop yet
<heat>
and thank god for that
<mjg>
dtrace can't loop by design
<mjg>
someone added lolglue to pretend therea re if statments
<mjg>
why don't yout port the obsd tracing framework smartass
<heat>
what's the openbsd tracing framework
<heat>
also if you think dtrace is so bad why don't you have eBPF
<mjg>
i'm not claiming it is so bad
<mjg>
i'm claiming if one is to port something, today ebpf is the better choice
<heat>
you said it's dying

it is

re: that whole compiling with -m32 thing. i think heat mentioned it. you want to compile as x86-64, but then use .bits32 inside the asm to force it to generate 32 (or even .bits 16 if you need it)
<geist>
then you can link them together because the linker just sees a set of 64bit .o files
<geist>
there are other ways to do it, but that's the most straightforward, provided you keep it simple and just do the minimum amount of work in 32bit code and get right into 64
<ilovethinking>
ohh okay
<ilovethinking>
thanks
<geist>
if you try to write too much 32bit and reference symbols in themain binary you'll get into relocation linker issues and you dont want to fiddle with that
<geist>
an artifact of the 16 -> 32 -> 64 extensions that has been done on x86 over the years is it's basically the same ISA. it's just had more bits added and some reinterpretation of some of the other bits as modes switch
d316d91 has joined #osdev
<geist>
but it means the assembler can just assemble the same instructions differently if it knows what mode you're assembling for
d316d91 is now known as d316d
<geist>
hence the .bits 16 or .bits 32 directive in the assembler. it'll just start generating instructions from then on out until you switch modes
<geist>
in that case if you're in a 64bit binary and telling it to assemble for 32bit then you're basically saying 'yeah i know what's going on here, dont worry about it' and the linker doesn't know any different
<heat>
it's .code16 and .code32
<heat>
I don't think GNU as supports .bits?
<geist>
ah yeah. i think it was bits something on nasm or whatnot.
<geist>
yeah you're right
<heat>
yep
<geist>
code16 makes more sense anyway, it's clearer what its for
<ilovethinking>
.bits is on nasm yea i was about to say
<geist>
the other semi clean strategy to all of this is to simply create a little front end stage of code that's completely independent of the 64bit code, and is glued on after linking. it's the 'cleanest' in the sense that both binaries are completely independent
<geist>
but it requires more steps and more knowledge of how to fiddle with binaries, so i wouldn't recommend it now

honestly, there is many free pdfs of minix on the internet, should i try to print one and learn osdev like that? Mainly is that i am focusing on UNIX/POSIX

As far as printed matter goes, the Minix books are some of the least bad, but Minix is also very opinionated and what's covered in the books isn't really the bits most people find interesting about osdev.

xv6 is more of a bit of software archeology

it's supposed to recreate the experience of the earliest builds of Unix

KNU stands for Kiev National University i think
<brunothedev>
i will not buy a minix book, it is like a minimum wage here, i would print the pdf
<heat>
it's probably expectable that linux, etc are hard to learn from, particularly for complete newbies
<klange>
Yeah, at textbook prices I would say don't bother with D&I.
<heat>
so in that sense, xv6 does its job fine. the basics are still there
<heat>
although it's a bit meh still, source code organization is severely lacking, so are comments
<brunothedev>
the only "documentation" i ve found on xv6 is a mit(i think) stundent notes on github
<brunothedev>
they copy code from netbsd and other too i think
<nortti>
the course material should be available at MIT's site
<klange>
Of my passive goals with my OS is to have something that is both complete enough to touch a bit of everything, while remaining simple in its design and layout so as to be fully comprehensible.

all in all, dh`'s OS161 is probably a much better resource than xv6
