im not a good example and not there yet...but i decided i would want functions for all "lock" type things. this means someone has to go actually implement them for whatever scheme/"backend" (whether it uses/calls asm or whatever). point: some of those might just limit a function to only one instance at a time. or silly things like uid/pid/gid/thread can only have X instances of a function running at a time, else it has to wait. thi
<kof123>
s more theoretical DOS protection perhaps, but seems doable
<kof123>
so not the "system calls" higher level stuff...but tiny functions that just lock a resource
<kof123>
or ref count, or whatever
<kof123>
when i dont know what i am doing i always aim for flexibility so as not to code myself into a corner
<mjg>
your dos protection will kill performance
<kof123>
*maybe* some high level stuff might limit number of instances by uid/gid/etc. but that is just fluff there.
<kof123>
well, itll all be optional. i mean, ifdef out as well if its that bad
<kof123>
its more like...you have a disk on a controller. how does this work? you queue requests? what is the point of letting a user queue more than the hw can actually do?
<kof123>
or whatever other combinations, x disks on y controllers
<kof123>
*try to queue. they will have to wait anyways
<kof123>
or "groups of functions" does not have to be individual functions
<kof123>
you can make your own queue, and then plop things off there when hw is ready
<kof123>
just havent got there yet lol
wlemuel has quit [Ping timeout: 250 seconds]

i do try to fail early when possible ...so user can decide whether they want to retry or not. probably slower, having to call function again...but gives user the choice what they want to do. probably slower, but i prefer flexible

with everything functions, then one can just go to sleep, retry after hardcoded period, try to be "adaptive" etc. functions everywhere has overhead surely, but it will have 100s of knobs to tweak

"you can make your own queue, and then plop things off there when hw is ready" the idea of e.g. uid limits...whats to stop a user from e.g. hogging a disk? or is that ok, use the hw, they got in first, let them use it, thats what its there for (like ram)?

In a link script, is there a way to tell the loader to load a specific section at a specific virtual address? I'm trying to get limine to load a stubs section of my boot stage at a particular virtual address but specifying . = 0x... is causing the output file to be over a gig in size, which clearly is not what I want. I have another PHDR for it and have it defined as .stubs { KEEP(*.stubs) } :stubs but it's putting it right at the end of the .text segment.
<junon>
Not sure what I'm doing wrong.
<junon>
Another question - I'm trying to defined the addresses of some extern symbols and do so with STUBS_START = . and STUBS_END=. but they're linked to address 0. If I do STUBS_START = ALIGN(4096) then it works. Am I misunderstanding the . symbol here?
<zid>
why do you have a weird unprintable symbol before those things you pasted is the real question
<Jari-->
spinlocks, mutexes, and semaphores2...
<zid>
where are you adjusting .? it flips meaning inside and outside of a section
<junon>
zid: was outside of a section when I tried
<junon>
also not sure about the weird character, I'm using element and connecting via bridge, maybe I need to update element
<zid>
"If no suitable region could be found, or there was no previous section then the LMA is set equal to the VMA. " is probably what you're hitting
<junon>
I didn't realize its semantics change depending on if it's in a section block; is outside the block a physical address and inside is the virtual address or something?
<zid>
It's kinda awkward to get it all straight, and a lot of people rely on the defaults to get what they want, so it all explodes the moment you don't want that
<junon>
that's exactly what's happening :D
<bnchs>
hi #osdev
<zid>
use some .blah 0xnumber some . = and some >phdr while staring at readelf until you get what you want :P
<bnchs>
you know what grinds my gears?
<junon>
I'm trying to decouple the boot stage and the kernel entry stage a bit, and when I switch out my page tables from the Limine supplied ones to the kernel's, I need the little stub I'm executing to be in the same spot.
<junon>
and want it to be out of the way of where the kernel will ultimately get mapped.
<zid>
AT() is probably easiest, thinking about it
xenos1984 has joined #osdev
<junon>
Mrh so readelf is showing everything correctly but limine is not loading it correctly, I think limine isn't built for anything strange like that.
<junon>
limine reports OOM
<junon>
just sticking it after .text and page aligning it before/after will work, I'll just have to re-map it myself

recursive page tables are inherently incompatible with upper-2GiB kernels (-mcmodel=kernel) aren't they?
<junon>
unless you make the self-mapped index something other than 511 of course.
<junon>
because the kernel itself would otherwise occupy index 512

Idk which version do they use. Modern gtk versions support integer hidpi on windows and at least it is not blurry, but hexchat is
<heat>
integer gui scaling is a scam
<heat>
what size do you want? giga small or giga large?
<Ermine>
At least this is what they implemented (easy part tbh), and afaik gtk people are stubborn on not implementing fractional part. They think that compositor should rescale windows to desired scale
<Ermine>
And windows doesn't do that if program announced hidpi support
<heat>
gtk people (and everyone else in the desktop linux world) are very stubborn on providing a shit experience for everyone :)

could have cloned win95's api and renamed it all to gtk_blah and had a better ui than I've ever seen on a linux machine

just sayin

i like opening gtk and qt and sdl apps and having 3 completely different UI styles

does sdl actually provide anything UI-wise?
<heat>
all configured through completely different methods
<zid>
there was something ages ago.. wxwidgets?
<zid>
That just made windows windows on windows
<zid>
I liked that

is that what wine uses? wine gets windows-ish styling

wine just implements gdi32.dll properly doesn't it
<zid>
uses libx or xcb or whatever
* CompanionCube
remembers dolphin used to use wxwidgets and moved to qt, iirc at the time the former didn't do hidpi
<Ermine>
At least plasma people tried to do some consistent looks with kde-gtk-config, but now gtk apps are moving to libadwaita I guess...
<zid>
and to wayland, which afaik is.. all statically linked?
<heat>
the problem with desktop linux is that everyone has a fucking opinion
<heat>
and they're usually all bad

so all the windowing is all going to be fucky on old binaries eventually, so that will be fun
<CompanionCube>
nah wayland isn't a UI toolkit
<zid>
I know
<CompanionCube>
old binaries will use XWayland, no?
<zid>
will use what
<heat>
wayland is not statically linked
<Ermine>
Well, windowing is fucky with X...
<zid>
oh did they revert that requirement?
<zid>
I've never actually uesd wayland, just saw everybody hyping it up before it was a real thing
<heat>
idk, I'm seeing a bunch of libwayland-*.so stuff in /lib
<CompanionCube>
maybe you're thinking of the stupid GNOME design choice where you have to provide your own titlebar?
<heat>
in fact fedora, debian all require shared lib everything
<zid>
nobody mentioned titlebars?
<Ermine>
btw gnome still didn't implement xdg-decoration protocol for server-side decorations
