Hello :) I'm really sorry if this is a stupid question but the forums and website are down rn. I am in the process of moving my OS from 32 bit using Multiboot to 64 bit using Limine (Using the 64 bit Limine bare bones template as a start). Except I am not sure how to print text to the screen in Long mode. Since limine gives a full framebuffer by default, is the next step to write a new set of TTY functions utilizing something like SSFN2 or is there a
<avery2004>
trick to using TTY the same way you can in protected mode?

what's ssfn2
<avery2004>
'Scalable screen font' on the wiki. Basically drawing characters to the framebuffer instead of sending characters directly to video memory
<heat>
>is the next step to write a new set of TTY functions utilizing something like SSFN2
<heat>
yes
<heat>
no idea what ssfn2 is but it sounds like osdev wiki garbageware
<avery2004>
heat: Thank you :) I was a little lost

take a bitmap font, it's pretty simple (bit set = draw with foreground color, bit unset = draw with background color)

i bought some cheap fragrance out of curiosity
<mjg>
it came with a free sample of anotehr fragrance
<mjg>
and i like it, except it's for women
<mjg>
life is though man
<the_oz>
oh nooooo my nose smells the vagina in that scent
<mjg>
so at first i thought they made a mistake
<mjg>
normally free samples match the product they are attached to
<mjg>
but then i remembered that most fragrances, including for men, are bought by women

or are in the portugesee taste alley

by any chance are browsing the lol cheap ass section or something resembling a real frag
<heat>
nope
<mjg>
cause anything < 10EUR is basically webdev of fragrance
<mjg>
erm, anything < 40 EUR or so
<heat>
these were all loewe

mon i use linux i need to compensate not taking baths with expensive perfumes
<mjg>
dior sauvage > bath
<mjg>
it is known
<mjg>
even so paint me surprised, i thought that at best you wear Axe
<mjg>
(or whatever other brand which is considered cringe today, back when i was in hs it was axe)
<heat>
they make deodorants
<heat>
crappy ones at that
<mjg>
i know
<mjg>
that's what i mean
<mjg>
no edt/edp, just a deodorant
<mjg>
and crappy one at that
<mjg>
a genuinely cheap borderline webdev frag you may try out is versace blue jeans

i mean idk your budget, presumably your allowance is not adjusted for inflation

<mjg>
heat: well if you can afford something more expensive, i can only suggest you *avoid* dior sauvage :D
<mjg>
heat: it's the most cliche non-cheap frag you can pick
<heat>
yeah i dont like that one
<heat>
i already have 2 perfumes anyway
<heat>
i was _maybe_ searching for a 3rd, but if i can't find one then no problem
<mjg>
there are companies which sell samples
<mjg>
you can get a collection to slowly work through
<mjg>
heat: do you post on r/arch btw
<mjg>
(or whatever the fucking sub it is)
<heat>
no
<mjg>
would be funny to ask arch users specifically what perfume, if any, they wear
<heat>
go to arch's offtopic irc channel lol

i fully expect the most upvoted answer to be "my sweat", and for it to be serious

Citizen reminder: Turning on -Werror for all errors by default is malcompliance and will be punished accordingly. It shall be opt-in or people will have a bad time when they use a different compiler version than you.
<nikolar>
good point
<heat>
why is werror on for release builds?
<sortie>
Bonus punishment for GRUB that has --disable-werror but then has a few hard-coded -Werror arguments in the makefile here and there.
<sortie>
heat, idk man, some people do this shit.
<nikolar>
sortie: send patchen upstream with the fix
<nikolar>
sounds like they added --disable-werror after someone complained and didn't check everywhere
<sortie>
nikolar: If I did that, I would never get any osdev done. Do you know how many many many patches I have?
<nikolar>
heh this is a very simple patch though, isn't it
<nikolar>
just shoot an email and forget
<sortie>
Honestly, no
<sortie>
Every upstream has different ways to contact them
<sortie>
Half the work is even figuring out how to file an issue or how to mail them
<kazinsal>
and some of them will expect you to become a package maintainer
<sortie>
Then convince them that they are wrong and I am right
<heat>
wasn't patching upstream your thing?
<nikolar>
kazinsal: how so
<nikolar>
sortie: it seems like it's pretty clear who's wrong
<sortie>
Then my patch isn't the correct autoconf magic cus who is able to understand Makefile.am and configure.ac that stuff is so opaque. I literally just patch configure and Makefile.in directly
<nikolar>
ah lol
<sortie>
nikolar: Then multiply that for 836K of patches (22113 lines) across 90 ports
<sortie>
I wanna do it? And I _have_ done it. It's just so much work.
<sortie>
So much back and forth
<nikolar>
eh fair
<nikolar>
that is a lot of patches
<sortie>
Most of my patches solve the problem de-facto but not well enough that the upstream would be able to commit it since they want to polish it an and integrate with the build system
<nikolar>
which is really the correct approach
<sortie>
If anyone wants to help software portability and cross-compilation of common software a great deal, talk to me, you can help upstream my patches for me
<sortie>
Half of my patches are Sortix specific of course, but the other half would really help most people also doing osdev and the community beyond

heat: Some of these new gcc warnings are wild. -Wformat-truncate and -Wformat-overflow are giving me pain to no end because I inject -Werror=format and that also affects those though they come in through -Wall

Even though my ports tree is largely up to date at this point
<sortie>
But updating the compiler doesn't make the ports any less worse (more or less) so they should still work but new warnings and -Werror causes mayhem
<heat>

maybe google was right all along

reject CFLAGS, reject CC, embrace bespoke build system with prebuilt clang straight off of master
<sortie>
Sortix has a slightly different ABI so things like pid_t, ino_t, uid_t, gid_t, etc. are different than Linux and poorly written software uses printf specifiers like %i and such assuming stuff that POSIX doesn't require
<sortie>
Since we're free to pick the ABI for stuff in <sys/types.h> subject to mild requirements
<heat>
don't tell me your uids are 64-bit?
<nortti>
I think they're size_t sized
<heat>
ugh
<nortti>
or wait, no, that was pids
<sortie>
Many such things are
<sortie>
pid_t is also intptr_t sized, like ino_t and dev_t too
<sortie>
Perfectly allowed by the standard and good software can handle it
<sortie>
But a lot of stuff doesn't.
<sortie>
Some militantly doesn't even use pid_t. Fuck you libglib.
<heat>
my pid_t is int, uid_t is unsigned int, gid_t is unsigned int, dev_t is 64-bit, mode_t is unsigned int, uid_t is 64-bit
<childlikempress>
heat: prebuilt clang from a 6-year-old master*
<sortie>
heat: The point is that all of these printf calls will just emit a -Wformat warning and explode at runtime. I need to make those compile errors
<heat>
where did you see that? shit like chrome and v8 use like a 2-week old master
<heat>
>and good software can handle it
<heat>
my software sucks then
<nikolar>
heat: what is this prebuilt clang thing about
<sortie>
heat: I mean software specific to Onyx doesn't need to handle other operating systems
<heat>
my software is mostly portable to everything
<nikolar>
keyword mostly
<sortie>
It's still good to write it properly portable
<heat>
i try to at least
<sortie>
If that is the goal of course
<heat>
but i'm not invoking the devil just to print a horrible intmax_t when %d will do
<heat>
pid_t is not explicitly an int but in practice it is one
<sortie>
%jd done boom
<heat>
how about: no
<sortie>
Your no has been rejected by -Werror=format.
<heat>
i also assume LP64
<sortie>
LP64 is more reasonable tho
<heat>
is it?
<immibis>
the words "short" and "long" are not reasonable
<sortie>
More or less everywhere. I mean I personally don't assume much but it's well defacto
<heat>
pid_t is historically an int and why do you have more than 2^31 processes live?
<sortie>
Well why have arbitrary limits
<sortie>
Sir this is a 64-bit processor
<heat>
nikolar, the big google projects (mostly related to chrome) all ship their own prebuilt clang you need to download. some support using the system compiler but are somewhat unstable when doing so
<heat>
sortie, security
<sortie>
Part of it is also that I don't recycle pid_t numbers
<zid>
how will I make a bitmap of pids now
<nikolar>

arbitrary limits are usually okay. like NFILE being 1024

That is not the GNU way

<immibis>
fun fact: it's called cdparanoia because CD drives used to not reliably give you the audio data stream, so it tries reading it a bunch of times, reading it backwards, etc, until it's consistent. I assume it helps with damaged disks too, like ddrescue.
