I lost you know, every single ~/.file equivalent though

those are easily replaceable given the password

Yesterday it was recommended here that I build some apps with C++ and Qt because I said I wanted to practice some app development before doing OS development.
<gaxar77>
I just installed qt last night.
k0valski18891 has quit [Quit: Ping timeout (120 seconds)]
<dinkelhacker>
Do you want to write your os in c++?
<gaxar77>
No, in C.
<gaxar77>
Eventually.
<gaxar77>
But maybe in C++.
<gaxar77>
I would not need to use new or delete or malloc or free.
<gaxar77>
But I don't know how the compiler would handle not having implementations of those things.
<gaxar77>
new and delete
<zid>
easy, it violently explodes if you try, including if you do things that cause it try internally
<zid>
which for C is trivial to avoid, because it doesn't do that
<zid>
for C++ you probably need to avoid a whole bunch of things and pass various flags
<gaxar77>
So, I guess not then.
<gaxar77>
Does MS use C++ in their kernel?
<gaxar77>
the Windows kernel?
<gaxar77>
I have to be honest, I only know C because I know C++..
<gaxar77>
And the language is not exactly the same as C++ without OOP.
<zid>
depends heavily on which era of C++ and which features you like to use, as to how different it is in practice
<zid>
it's rather a.. large toolbox
<gaxar77>
Well, I only use the first standard, as that's mostly what I've learned.
<gaxar77>
of C++, that is.
<gaxar77>
Has anyone here implemented an execution engine that runs user mode apps in their OS?
<gaxar77>
Wouldn't it improve security if all user mode apps ran in an execution engine?

Or is that a bad idea?
<sham1>
What do you mean by execution engine here
jjuran has quit [Ping timeout: 246 seconds]

Like the JVM or the CLR.

Those are called execution engines, I think.

VM, would be the normal word
<zid>
you know, like jVM
<gaxar77>
I was trying to avoid confusion with things like VirtualBox.
<sham1>
Well not only have people done so, there even are OSes where your "userland" is at the same layer as the kernel and the security is provided by the runtime environment

The point being that it being Rob Pike's post is why it makes no sense. After all, he's responsible for Go. And that's all you need to know
<heat>
just use a be32tohost or le32tohost and pick consistent byte ordering
<heat>
amen
<mrvn>
heat: ntoh?
<heat>
he's basically saying "just open-code endian conversion and integer reading with a char * and a needle"
<sham1>
Well that is indeed what he's saying. Although it's also helpful when you're writing the conversion yourself even if you abstract it away
<heat>
it's silly code written by silly UNIX geezers
<sham1>
Besides, I think the more important thing there is the sentiment: don't care about your host byteorder, let the compiler worry
<heat>
what
<mrvn>
Nowaday compilers are smart enought that when you read 2-8 bytes from a stream and assemble an int from it that they just do that as a single read + conversion if needed.
<sham1>
Yeah. They can also optimise memcpys into load instructions as needed
<mrvn>
Used to be doing the htobe32 or such was faster.

hey lads, i'm currently stuck on virtual memory, i am 100% sure i map out the framebuffer correctly but for some reason after loading cr3 and trying to print the print pagefaults
<ilovethinking>
is anyone willing to look at my initialization code
<ilovethinking>
to_virt does physical address + hhdm offset
<mrvn>
ilovethinking: print the page tables in qemu
<ilovethinking>
info tlb righ
<mrvn>
and you should be loading cr3 twice. Once to map the kernel to virtual addresses and a second time to unmap the physical addresses after you jumped to virtual.
<ilovethinking>
mrvn: info tlb literally froze my qemu
<ilovethinking>
since i mapped out the first 4gb
<mrvn>
shouldn't freeze. it just prints a lot
<mrvn>
are you mapping 4k or 2Mb pages?
craigo has quit [Quit: Leaving]
<mrvn>
or even 1G, then it's just 4 entries
<ilovethinking>
4k mrvn
<ilovethinking>
it froze cuz there are so many
<ilovethinking>
ok it printed
<ilovethinking>
after like 3 minutes
<mrvn>
do you have qemu output to the terminal or graphics?
<mrvn>
ilovethinking: at some point you will write some console / video driver.
<ilovethinking>
mmm yeah
<ilovethinking>
but i wont be able to debug
<mrvn>
serial is a great way to debug :)
<mrvn>
anyway, your page table looks broken.
<ilovethinking>
how come
zid has joined #osdev
<mrvn>
If you map 4G then I would expect output for 0-4G and -2G to 0. You seem to have mapped a lot at -16EB and then only 5 pages at -2G for the kernel.
<mrvn>
and those mappings have odd physical addresses
<mrvn>
The last page even has X and W. you should never have that.
<heat>
ilovethinking, where are you page faulting and what error code?
<ilovethinking>
0E at print

<ilovethinking>
error 0008
<heat>
ok now that's up to you to decipher
<heat>
exercise left to the reader
<mrvn>
ilovethinking: you should map just the bare minimum, set a breakpoint after loading CR3 and then print the table.
<heat>
plus cr2 and the IP (which gives you the faulting instruction)
dude12312414 has joined #osdev
fedorafan has quit [Ping timeout: 248 seconds]

When set, one or more page directory entries contain reserved bits which are set to 1. This only applies when the PSE or PAE flags in CR4 are set to 1.

so that's the error

<bnchs>
what if you wanna map a struct to a 32-bit program's space, but that struct has 64-bit pointers, do you rewrite the struct to have 32-bit offsets and force the OS to use a function to dereference them, or do you translate the structs everytime the program wants to access them
<heat>
bnchs, obviously you need to get new pointers to 32-bit space
<bnchs>
yes
<heat>
well, there you go
<bnchs>
that s obvious
<heat>
there's your solution
<yuriko>
translation seems better if there's a lot of memory
<bnchs>
but do you rewrite the struct's implementation in the OS, or serve a translation in the memory map
<bnchs>
translating the 64-bit pointer to the 32-bit memory space
<heat>
you probably want to 64->32 that other struct too
<bnchs>
obviously
<heat>
then what's the question?
<yuriko>
if the memory is being accessed often or there isn't much of it, dereferencing sounds good
<heat>
if you want to 64->32 you'll need a new pointer and new memory so you can do the translation for that other struct too
<bnchs>
the question is, should the OS keep using a function to dereference the 32-bit pointers to access it
<yuriko>
if I understand right
<yuriko>
but that's just an opinionnn
<bnchs>
if the structs were to be rewritten
<bnchs>
or the OS should translate the structs for the program if the program accesses it
<heat>
i don't understand what you mean by "function to deref 32-bit pointers"
<bnchs>
heat: function to convert 32-bit pointers back to 64-bit pointers
<Amorphia>
mjg: does OpenBSD have super crap scaling?
<heat>

<heat>
Amorphia, absolutely
<Amorphia>
heat: ohno
<Amorphia>
heat: how come?
<heat>
Amorphia, my OS beats OpenBSD and NetBSD's ass
<bnchs>
the OS has a base address it adds to the pointer to make it accessible to the OS
<heat>
huge locks, bad lock implementations
<Amorphia>

<Amorphia>
thank you for your feedback, heat
<heat>
not a problem
<heat>

<Amorphia>
:D
<Amorphia>
good to know
<heat>
it is a blast ngl
<yuriko>
:D
<bnchs>
it's what i meant by that 64-bit pointer thing
<heat>
bnchs, yeah i... i have way too little context to actually understand what you're doing
<heat>
so i'll just smile and wave
<bnchs>
cool
<Amorphia>
bnchs: you could provide more detailed context to your current project / present issue
<bnchs>
alright
<Amorphia>
half of programming is learning how to explain complex problems
<Amorphia>
that's why we use rubber duckies
<Amorphia>
half the time, if you can explain it, you can already solve it
<bnchs>
the OS gives the program a memory map that's 32-bit, that maps to certain structs in the host OS's 64-bit memory space
<bnchs>
the layer gives the program a memory map that's 32-bit, that maps to certain structs in the host OS's 64-bit memory space
<Amorphia>
what OS, what's the host and what's the program, and what's your goal here?
<bnchs>
what i'm trying to do is balance out the processing load of either translating whenever the program is trying to access the struct
<bnchs>
or the structs having 32-bit pointers and the OS having to convert it back to 64-bit everytime
<bnchs>
Amorphia: the host is a standard Unix-like machine, i should have elaborated that it's a compatibility layer
<bnchs>
so me saying OS is wrong again, dumb me
demindiro has quit [Ping timeout: 260 seconds]
<bnchs>
the program is a.. program that runs on a 32-bit emulated processor
<bnchs>
like i KNOW that i can do either, but i'm just trying to see which is best for less processing load
<Amorphia>
tbh im still not sure if im understanding what you're up to, but im far from the most knowledgeable about osdevvy things here
<bnchs>
can you tell me what you wanna know?
<Amorphia>
nope. i am too inexperienced to formulate well-crafted questions about your problem space
<Amorphia>
heat: are you making any sense of bnchs explanations?
<bnchs>
the pointer translation method may also need double the memory to store the translated struct
<yuriko>
Probably just use a LUT for translating the 32-bit struct to the 64-bit OS memory?
<yuriko>
I might be forgetting what a LUT is
<bnchs>
also i could have a flag to tell that the structs have been modified to translate it again in the cache
<yuriko>
I think that would be too resource intensive
<bnchs>
yeah that's the problem
<bnchs>
also a lookup table?
<heat>
Amorphia, no i was taking a shit
<Amorphia>
heat: was it a good shit tho
<heat>
but I also don't get it
<heat>
yes, very good
<Amorphia>
great, im happy for you :3
<heat>
this is a certified colon three moment
<bnchs>
then i am bad at explaining problems
<heat>
colon in many different ways
<yuriko>
a dictionary is what I mean I think. Key-value store, with the key being the 32 bit address and the value being the 64 bit address
<yuriko>
And yes I did mean lookup table, I’m just not entirely sure what that means
<bnchs>
the memory map is basically just a list of maps that has 3 proporites, the 64-bit host pointer, the 32-bit memory space pointer, and the size of the map, whenever the program tries to access something in it's memory space, it looks through the list to see where it's trying to access
<bnchs>
well, the layer looks through the list
<yuriko>
Use the memory map and don’t cache or rebuild I think
<bnchs>
uhh what do you mean by that
<yuriko>
When a 32 bit program requests the memory, the layer should search the memory address in the key value store, get the 64 bit actual address, get the value from that address, and pass it to the 32 bit program
<bnchs>
sorry, if i didn't explain my problem correctly, since your answer was out of scope, but what i meant by translating a struct's pointers is that, imagine if there was a struct with a 64-bit host pointer on it, that the layer can easily access, but if the program tries to access the struct via the memory map, it'll see that it has a 64-bit pointer that it can't access
<bnchs>
there's either translating the struct, which is resource-intenstive, or rewriting the struct itself but forcing the layer to use a function to access it
<yuriko>
Oh I see
<bnchs>
all should give the program a structure that has the 32-bit pointer on it instead of that pesky 64-bit pointer
<bnchs>
in the most efficient way
<yuriko>
I understand what you’re saying but idk which would be faster
<bnchs>
yeah that's the problem :3

you can't perfect sched no matter what though

A graphics toolkit is not the same as a GUI toolkit.

then work backwards from that to figure out what to do

what are you trying to accomplish?

I just want to build something like a GUI toolkit in C++.
<geist>
then build one. as gog said

go design it and implement it

<gog>
design by doing
<geist>
ah so then lets revise the 'what do you want to accomplish'
<heat>
gog, are u unix
<gaxar77>
What do you mean?
<geist>
so now what you want to accomplish is 'i want to rebild an existing gui toolkit in c++'?
<geist>
because you dont want to design a new one
<geist>
trying to narrow down what the ask is to something concrete
<gaxar77>
Well, can't I just let the design emerge as I go?
<gog>
yes
<gog>
you can absolutely do that

because you said you dont know how to design anything

that's not really an operating systems question
<geist>
trouble here is you're so in far over your head you're just grasping at straws

suggestion: start with something a bit lower and work up
<gaxar77>
Well, I think I'll attempt a GUI toolkit.
<geist>
it's okay to start that way, everyone starts with zero knowledge
<gog>
arguably i still have zero knowledge
<gog>

well, frankly a gui toolkit is still pretty advanced

ah, so the 3rd dimension is bloat?
<geist>
yay rotating file viewer!
<morgan>
for viewing rotating files
<geist>
in 3d tianglix has pyramid poer
<gaxar77>
Windows XP is said to have been the best Windows OS.
<bnchs>
hi
<gaxar77>
I like its appearance.
<moon-child>
3rd dimension is a scam made by lizard people
<heat>
CompanionCube, the 3rd dimension is entirely redundant
<geist>
a pyramid being a triangle with a flat arse
<bnchs>
CompanionCube: can i fall in love with you
<CompanionCube>
bnchs: yes
<CompanionCube>
Results may vary.
<gaxar77>
I miss the Luna theme.
<bnchs>
i will not throw you down the aperture science incrinator
<geist>
zid: so you reverted to an even older computer to get it done?
<gaxar77>
Or XP theme.
<geist>
heh the default XP theme. AKA Tellitubbies theme
<gaxar77>
Why did they call Windows XP a fisher price OS?
<gog>
oh damn i want some of that tubby custard
<geist>
because it looks like it
<geist>
i aways immediately reverted it to the win2k theme
<gog>
same
<bnchs>
i liked the windows xp theme
<bnchs>
am i weird?
<CompanionCube>
bnchs: approved.
<geist>
the default windows had these big blue plastic looking things with rounded corners
<gog>
i only got xp because i lost the key for my copy of 2k
<gaxar77>
Why did Microsoft abandon the XP theme?
<geist>
like it was big plastic toys so your kid doesn't poke their eye out
<geist>
it was bold and stupid
<gog>
it wasn't very attractive really
<gog>
the icons were ok
<CompanionCube>
the real bad theme was the windows 8 one
<gaxar77>
I prefer that to Windows 10 and 11 look.
<heat>
CompanionCube, w8 was fine
<heat>
xp was always crap
<gog>
i unironically like the new flat theme
<geist>
yeah really it was the window decoratios that irked me on xp. and the blue theme being so bold. outside of that the icons and whantnot were fine
<heat>
vista probably peak theming in the 2000s
<geist>
which is why i always switched to win2k windows
<gog>
i hated the start button
bgs has quit [Remote host closed the connection]
<gog>
why did it have to be so green and obnoxious
<heat>
everything was obnoxious, it was the 2000s
<gaxar77>
XP was the first NT OS with Win 95 shell code.
<geist>
yah i like that modern stuff has finally reverted back to fairly tasteful and minimal
<heat>
windows 11 looks great
<heat>
it also works great
<gog>
it's fine i guess
<gog>
i don't like the context menu
<geist>
same on mac to be clear. early 2000s macosx was similarly gaudy
<geist>
it was very candy looking, etc
<lav>
I miss it tbh
<geist>
it was just the trend of the times, design goes through these cycles
<gog>
y'all remember when kde-look.org had like 3 different os x glassy themes
<heat>
you know what's real bad?
<heat>
default linux DE/toolkit theming
<geist>
default gnome now
<heat>
always looks like a really cheap knockoff
<heat>
gnome is actually probably better than the other ones
<heat>
at least better than KDE
<gaxar77>
How does XWindows know what to draw? It received draw commands or bitmaps?
<geist>
yah that's true, i haven't looked at most of the really bad ones
<heat>
KDE's existance is basically to be a cheap Windows dwm.exe
<gaxar77>
receives
<gog>
i like plasma shut up
<geist>
work is trying to force everyone to the new gnome ui, but i'm holding onto cinnamon with my cold dead hands
<gaxar77>
Are Microkernels inherently slow?
<gog>
yes
<gaxar77>
There is no solution to the IPC problem?
<heat>
geist, try gnome, its actually Good(tm)
<geist>
heat: uh. no.
<gog>
there are no solutions to any problems, only temporary fixes
<geist>
it has a whole list of things that irk the fuck out of me, including the big one: lack of desktop icons
<geist>
because 'nobody wants that'
<gaxar77>
What do yo mean?
<heat>
geist, lol
<gog>
all problems are subsets of the real problem: that the universe we know will no longer exist one day
<geist>
wasn't always the case, but theys eem to be doubling down on some particular design paradigm that i'm not down with
<heat>
geist, just hope goobuntu doesn't cut cinnamon packages or whatever
<geist>
yes, i know.
<heat>
or glinux or whatever you're calling it these days
<geist>
yep
<gog>
glinux sounds naughty
<geist>
the desktop is so important to me. i use the shit out of it as my medium term space
<CompanionCube>
i mean, being a dwm.exe knockoff is better than being a knockoff of something worse, like GNOME is
<geist>
icons organized by how my brain works, etc
<gaxar77>
I read that you have to design an OS before beginning to code, and that no other way will work.
<geist>
i store docs on it temporarily etc
<heat>
CompanionCube, what's GNOME a knockoff of?
<gog>
gaxar77: lmfao what
<CompanionCube>
heat: mac?
<gog>
you can just do it
<gog>
if you're an amateur just do it
<heat>
CompanionCube, hmmmmmmmmm. not quite IMO
<gaxar77>
I have a book on UML.
<geist>
gaxar77: quit reading about it, and do it
<geist>
oh god, throw that immediatle in the trash
<gaxar77>
I haven't finished it.
<geist>
dont. stop and throw it away
<gaxar77>
Why?
<heat>
hahahahahahaha
<gog>
UML is not going to help you write an OS
<heat>
yes it is use UML
<heat>
and all the design patterns
<heat>
GoF, SOLID, whatever the fuck
<heat>
use them all
<geist>
oh heat, you silly person
<gog>
i like me a good proxy object
<gog>
oooh oooh
<gog>
PIML
<CompanionCube>
heat: and do it in Java/C#!
<gog>
PIMPL
<heat>
GRASP
<gaxar77>
So what's wrong with UML?
<gog>
nothing, only that it's not going to help you, a rank amateur, actually get to business writing anything resembling a kernel
<gog>
UML is for large teams engineering large systems
<gog>
and coordinating their work
<gaxar77>
ok
<geist>
right. ts a bunch of tools that software engineering uses when hypothetically dealing with thousands of people on a large project
<gaxar77>
oh ok
<geist>
it has very little to offer an indivudual
<gaxar77>
oh ok
<CompanionCube>
or for making fancy diagrams in your documentation, i guess?
<geist>
and it has a bunch of nonsense that'll just slow you down if you try to use it yourself
<heat>
UML and OOP design patterns are only good for real programmers software engineers working on REEL BIZNESS PROGRAM
<gaxar77>
I see.
<gog>
gaxar77: find a hello world tutorial and figure out how to make interrupts fire or something
<gog>
that's how i started
<geist>
and somewhat more dangerously it can sort of lead you astray to what you should be doing right now
<gog>
i now have what is almost nearly a kernel
<geist>
which is getting hands dirty and learning
<geist>
by *doing*
<geist>
right exactly what gog suggests. get in there and start doing, then you'll start seeing what really matters and you'll have more knowledge to know what to learn next
<gaxar77>
Shouldn't I learn a lot of assembly first?
<geist>
dont think of any of this as a series of linear tasks
<geist>
do A then B then C
<gog>
you can learn some assembly as you go
<klys>
if you read the wiki it'll teach you the tricky assembly you want to konw
<geist>
it's all at the same time, you start learning assembly by writing assembly, reading it, etc
<gaxar77>
ok
<heat>
can you use UML with assembly?
<gog>
sure
<gog>
but why
<heat>
because it's good
<geist>
problem is when you get started you dont know what you dont know
<klys>
user mode linux or unified markup language
<geist>
so everything seems equally important
<gog>
klys: latter
<gaxar77>
OS Dev has a tutorial on writing a bootloader, loading a kernel, and switching to protected mode and stuff, right?
<geist>
but once you start doing things you start to get an idea of what matters and what doesn't then you can focus on what matters
<gog>
yes
<gog>
osdev wiki has all of that
<geist>
because it'll become more obvious over time what the next steps are
<gog>
it's of varying quality and coherence
<heat>
klys, unified markup linux
<klys>
haha
<gaxar77>
I've been having trouble getting MinGW.
<gog>
and some of it is deliberately broken to prevent people from just copying it without understanding it
<gog>
you don't need mingw
<gog>
use clang
<heat>
gog, yes haha deliberately
<gog>
heat: :3
<gaxar77>
Do the OS Dev tutorials take clang into account?
<gog>
i mean the task switching code example is broken
<heat>
COLON THREEEEEE
<gog>
i know because i cribbed the whole thing and had to make it work
<gog>
and i'm going to write my own at some point
<gog>
yes colon three
<heat>
hello im gog and welcome to my mtv crib
<gog>
gaxar77: not all of them no
<gaxar77>
oh
<gog>
but the point is
<heat>
do you have a pinball machine and arcade games in your womancave
<gog>
that if you're going to come in here and talk about programming stuff we're eventually going to expect that you have something to show for it
<gog>
heat: no i fucking wish
<heat>
shouldn't have called mtv into your crib then
<heat>
what a disappointment
<gaxar77>
Well, I'm having a hard time staying focused.
<gog>
i'm neurodivergent too
<gog>
it's fine
<gog>
you'll find something that holds your focus eventually
<gaxar77>
I have schizophrenia and I probably need certain meds.
<gaxar77>
What's not fair is that I started a Java app that does that and someone told me it was probably a waste of time.
<gog>
that's unfortunate
<gog>
it's not a waste of time if you use it and like it
<klys>
I would recommend keeping your code because it's yours and you may want to extend the functionality in the future
<gaxar77>
ok
<gaxar77>
I don't have the motivation to do that much coding.
<klys>
shelf the old stuff and back2basics
<gog>
one step at a time
<gaxar77>
How do you make the ISO according to your own custom file system?
<klys>
mkisofs xorriso or genisoimage have man pages you can read, you might want joliet rockridge and el torito
<gaxar77>
ok thank you.
<gaxar77>
Well, I think that I should probably still make the GUI toolkit first for an existing operating system.
<klys>
are you looking for an operating system to hack? what features do you need?
<gog>
i don't remember what i was working on last night
<gog>
and it's already almost midnight :'(
<klys>
# history | less
<gog>
hm
<gog>
maybe tomorrow when i'm more fresh
<gaxar77>
Actually, I wanted to expand Minux with a runtime environment for apps, and GUI if it doesn't already have one.
<gaxar77>
But I never used Minux..
<klys>
how did you learn about minix? were you studying a book?
<gaxar77>
I just watched a youtube video about it.
<gaxar77>
I don't remember, but I was lead to a video.
<klys>
if you read the wiki page for Minix you might be able to point out its salient qualities as you understand them
<gaxar77>
Does Minix have a GUI?
wootehfoot has quit [Quit: Leaving]
<gaxar77>
All I know about Minix is that it's a Microkernel.
<gog>
xorg runs on minix
<gaxar77>
What' that?
<klys>
freedesktop
<gaxar77>
oh.
<gaxar77>
Is it a full desktop environment?
<gog>
no
<klys>
Xorg (or X.org or freedesktop.org or X11 or X11R6) is an X-licensed protocol-centric system for graphics communications and supports the use of terminals and third party window managers and compositing systems.
<gog>
it's an implementation of X11
<gaxar77>
That's what I thought it was.
<gaxar77>
So, are there any GUI toolkits written for it?
<gog>
many
<gaxar77>
oh
<gaxar77>
Are there any VMs written for Minux, like the .NET CLR?
<gaxar77>
Minix
<gog>
i mean you can try to get mono running on it
<gog>
maybe asp.net core
<gog>
that'd be a lot though
<gaxar77>
I see.
<gaxar77>
Well, there's nothing I can do with Minix then.
<CompanionCube>
inb4 go retro and run Xaw/Motif on MINIX X11
<gog>
lesstif
<klys>
the java runtime environment and the common langauge runtime and the llvm are bytecode layers built on top of existing native systems.
<gaxar77>
I know.
<kof123>
twm. you may minimize programs to "desktop icons"
<heat>
CompanionCube, cwm or death
bradd has joined #osdev
<klys>
anymore qemu's tcg is also a popular bytecode commonly referred to a a virtual machine
<gaxar77>
Is there actually an interrupt on Windows that creates a Window, raised by CreateWindowEx, or is that functionality implemented in user mode?
<gog>
interrupts are captured by the io subsystem
<gog>
the uh the HAL
<gog>
it has nothing to do with window creation
<gaxar77>
interrupts are used to provide functions to user mode apps, aren't they?
