105.8% CPU?! Wtf
inner oak
i was lazyass all this time
lazy alloc is done 50%
also i want to make instead of mounting initrd copying initrd to tmpfs but doing some cow
for example instead of allocating memory and copying the entire file, I'll point file content pointer directly to the content in the initrd
but on write ill do this anyway and forget about initrd
inner oak
now my vmm finally have good unmap
inner oak
lazy alloc is done
now i can use more than 2 glxgears
and i need to implement disk driver and port something
inner oak

inner oak
maybe issue is i didnt implement any behaviour when process tries to write with zero count
like i saw in man pages what poll have some behaviour when there's zero message in stream
inner oak
so what i have
dbus have two threads
my test application fails on dbus_connection_send_with_reply_and_block
at end first thread reads socket and gets EAGAIN, second thread gets this too and both poll unix socket fd with which they are connected
inner oak
probably strace can help if i compare behaviour on linux and orange
inner oak
probably i found issue
it can be what my msg_send writes stuff one by one and suddenly after the some message scheduling interrupt occurs and other code which polls read this and ignores second message which msg_send need to send
i need to finally make msg_send syscall instead of just writing all iov in mlibc sysdep
inner oak
it can be what my msg_send writes stuff one by one and suddenly after the some m...
no its not issue
i compared linux strace and mine syscall logs and maybe issue can be what dbus dont like chmod stuff for service file
(it tries to stat every service in dbus service directory and on linux it stats all files but on orange it just stats one file and dont want to do anything)
inner oak
i compared linux strace and mine syscall logs and maybe issue can be what dbus d...
i need to fix chmod from ustar because it broken
inner oak
actually it just requires fd passing
inner oak
so finally after 71 syscalls (~15 of them are not mlibc sysdeps) i implemented my first linux sysdep
inner oak
because of the holidays i can finally develop orange a lot of time
inner oak
passing fd support is half done
inner oak
fd passing is done and it requires ucred too 
inner oak
all is finally implemented and now i need to debug some eventfd related bug
inner oak
wtf (its linux strace)

is this even possible to share fds after clone ??? (fd 10 eventfd is somehow shared and used after some time)
did i missed something
a
all this time i was ignoring what clone flags mean
so fd copying to child in clone() will be just removed
and i need to remove some race conditions because all fd related stuff was lockless just because i didnt care about shared fds
but now when dbus requires it i need
onyx matrix
working on this until the very end of the year is based
inner oak
working on this until the very end of the year is based
my target was find out why it dont want to work
i made it before the end of the year
onyx matrix
cause I'm stuck at a family home eating dinner
inner oak
but now when dbus requires it i need
when i finish that dbus pain i finally will be able to port xfce
because its required for xfconf
sharp coral
Kewl same timezone
inner oak
but now when dbus requires it i need
after 2-3 hours comparing linux strace and my syscalls log i realized what eventfd somehow from eventfd turns into fucking stdin/stdout
but index is 5 so maybe it tries to dup2
inner oak
all this time it was failing to write this fd
inner oak
finally i fixed this
now at-spi can start create socket and etc.
but now gtk dont want to connect to it
and xfconfd dont work too
debugging gtk and dbus stuff is really pain
inner oak
inner oak
who came up with these names
inner oak
tomorrow my target will be finally fix all bugs related to dbus
inner oak
and it means its time to implement signals <:nooo:750466870993223750>
nvm
fortunately it tries to SIGKILL
onyx matrix
and it means its time to implement signals <:nooo:750466870993223750>
Wait you don't have them?
inner oak
Wait you don't have them?
no
onyx matrix
how did you get so far without them 😭
inner oak
how did you get so far without them 😭
i wish ill never implement them
inner oak
and now it requires shutdown()
(unix socket close)
but my unix socket closing logic is trash
i need to fix this
inner oak
so i ran xfwm4 but it dont want to draw window borders
probably it requires signals and setitimer
idk how but glxgears fps increased
thorny swallow
so i ran xfwm4 but it dont want to draw window borders
how did you even learn to make a os in cpp everything tell me use c and assambly
jaunty oxide
By knowing c++ and using that instead
inner oak
how did you even learn to make a os in cpp everything tell me use c and assambly
you can use other languages too
like rust or ada
thorny swallow
you can use other languages too
nah c++ is cool
inner oak
so i ran xfwm4 but it dont want to draw window borders
tomorrow ill implement unix signals
if this is not unix signals then i need to look at xfwm src
thorny swallow
how did you learn cpp and os dev?
inner oak
how did you learn cpp and os dev?
idk
inner oak
if this is not unix signals then i need to look at xfwm src
also im thinking about xfwm src destruction
like
if i remove something on linux it must broke
so ill try to removing some stuff until i got same result on orange and linux
and it will mean from where there's issue / which code can give me hint
inner oak
bruh
if i add more syscall to my syscall table it breaks
ig my global constructors are broken ?
inner oak
i moved syscall to asm and now all is fine
inner oak
tomorrow ill try to test xfwm again but with implemented timer stuff
at-spi doesnt works but ig it just requires inotify stuff
inner oak
bash dont want to work if i enable sigaction syscall
inner oak
finally signals are implemented
if xfwm will not work now then i give up on this
and ill start implementing nvme driver and ext2
inner oak
after ext2 ill do audio stuff
inner oak
real
inner oak
tomorrow my target will be finally fix all bugs related to dbus
i found another issue
idk why but dbus instead of passing pipe just passes /dev/null to dbus-daemon when doing exec
inner oak
it requires cloexec
inner oak
idk why but dbus instead of passing pipe just passes /dev/null to dbus-daemon wh...
it looks like normal behavior
inner oak
im dumb
instead of actual result (for example fd which was dup) i was giving just ret
and because of this dbus didnt want to work
finally i fixed at spi
jaunty oxide
white karma
im porting mate rn
Nice
inner oak
probably it crashes because i dont have statx
i have last weird bug
something is writes to already freed memory and my fds getting broken
inner oak
something is writes to already freed memory and my fds getting broken
fixed
instead of if(used_counter == 0) idk why i used if(1) in fd freeing
inner oak
im trying to make some syscalls to lockless
vast lake
i ported roblox lua
Lolool
inner oak
my no follow symlink stat is broken
white karma
How many hours per day do you work on Orange
inner oak
How many hours per day do you work on Orange
i have a lot of free time
inner oak
after statx ill improve my tmpfs and ill implement cp, rm, mv and etc. syscalls
inner oak
right now im adding directory support for rename
after this ill implement rmdir and unlink
inner oak
right now im adding directory support for rename
with this ill do a lot of tmpfs optimizations
inner oak
my tmpfs lookup is trash
inner oak
initrd to tmpfs copy time is 90% decreased
inner oak
my tmpfs lookup is trash
i have a choice do tree way or hash magic
inner oak
finally i got fast boot time
inner oak
i have some weird bug on cpu with more than one core
futexes just dont want to work properly
sly sandal
finally i got fast boot time
congluration that so fast
inner oak
im abandoning the idea of userspace drivers
because im too lazy to implement fast disk access when there's userspace disk driver
inner oak
so i got situation where st gets from 100 fd index to 200 after few syscalls
maybe if i debug it syscall by syscall i can see what's happening
quiet dome
i need to implement fd closing properly
this was intended reply
inner oak
so i got situation where st gets from 100 fd index to 200 after few syscalls
found issue
i forgot to remove fd from list when open fails
inner oak
wtf
so issue why mate-panel dont works is wnck-applet tries to use paths to my host gcc cross compiler instead of sysroot
onyx matrix
I've had similar issues before, there should be a compile option to change it to a proper path
It wasn't with mate obv but it was a similar issue
inner oak
im thinking about implementing futex table which will contain waking counter for each futex pointers
just because apps get stuck on futex wait when there's a lot of cpus
inner oak
I've had similar issues before, there should be a compile option to change it to...
which options
onyx matrix
which options
Dunno
inner oak
so i did some random shit and all smp issues fixed
i have no idea what but im very happy
and it means time to implement statx
inner oak
i have another race condition
probably issue is in sys_clock_get
wait i got a hint
its race condition result so issue in vfs
inner oak
its race condition result so issue in vfs
maybe disabling half of syscalls can tell where race condition can be
inner oak
maybe disabling half of syscalls can tell where race condition can be
fixed
issue was what strtok is thread unsafe
inner oak
right now im implementing some stuff which glibc requires to work
inner oak
why it requires so much stuff
inner oak
im thinking about build system for linux compat userspace
maybe cross compiler would be good
inner oak
bruh im spending a lot of time just cuz gcc dont want to compile
white karma
The fate of osdevers
inner oak
now glibc dont want to go to /usr/lib instead of /lib64 😭
inner oak
after glibc stuff ill implement evdev for x11
inner oak
these linux names are wild 💀
white karma
Lmao
inner oak
i need to make some kind of stackframes for signal
like to make sigreturns a lot of times if there's signal in signal handler
inner oak
dfsfckxkvnasdjkfdkm
i have no idea why it doesnt like my argv
it gets corrupted
maybe issue in mmap
issue was in MAP_FIXED
i just disable this
because im lazy to implement this in my vmm
sly sandal
glibc dont likes my argv
maybee you forgot the last NULL entry
idk
or maybee you don't pass env as third arg
inner oak
or maybee you don't pass env as third arg
i already fixed this
mmap MAP_FIXED was broken and it broke argv
inner oak
tf is clone3
last geyser
clone2 + 1
bleak ravine
these linux names are wild 💀
How could the maintainers allow that 
inner oak
bash and my tty in userspace with linux compat works
onyx matrix
when job control
inner oak
when job control
it requires some generated by systemd file
onyx matrix
what?
inner oak
onyx matrix
why would it require systemd
inner oak
or maybe its just some another file
onyx matrix
no its a tty thing
inner oak
no its a tty thing
yes it looks like i didnt implement something in tty ioctl
inner oak
tomorrow ill implement evdev and ill try to run xorg
inner oak
getdents64 is implemented
onyx matrix
And this is why I do my own syscalls lol
inner oak

🗣️ 💥 🔥
inner oak
i cant compile evdev driver for xorg cuz of this 🙏
inner oak
today i converted to linux ~50 syscalls
inner oak
time to implement alarm() and setitimer()
vast lake
time to implement alarm() and setitimer()
Huh what does alarm() do?
vast lake
send sigalarm after some time
Ahh.
inner oak
(yes testcases written by ai dont hate me)
vast lake
(yes testcases written by ai dont hate me)
AI generating test cases is fine tbh
Like it cant f up test cases right lol
inner oak
xorg requires abstract sockets for linux platforms
time to implement it
maybe instead of implementing it i can not rely on strlen and just copy sockaddr
inner oak
interesting what if i try to use debian userspace which created with debootstrap
vast lake
interesting what if i try to use debian userspace which created with debootstrap
debian userspace???
huh

Cool
inner oak
right now im fixing some bash bugs (related to ioctl maybe)
inner oak
right now im fixing some bash bugs (related to ioctl maybe)
it looks like readline dont like something and immediately exits
inner oak
wait bruh im dumb
i looked at wrong linux syscall table
for arm instead of x86_64
i dont want to implement pselect so time to use sigma pselect to poll converter from astral
inner oak
finally i fixed readline
and finally i booted to debian userspace
now i can use apt for some apps instead of building something (only from host with chroot for now cuz i dont have networking)
inner oak
i want to move my tty to kernel too
cuz i dont want to compile it again and again when doing debootstrap
time to say to my beautiful tty bye bye 🥀 😔 😭
white karma
Why
white karma
Ah mb didnt read above
inner oak
and finally i booted to debian userspace
i wish some day in future ill get working apt

i have some issue
absolute elfs are broken
i didnt wanted to support them but debian have gcc cc1 absolute, not pie

krill issue
inner oak
krill issue
i thought im not going to touch elf loader when i wrote it months ago
inner oak
they are fine
i need to look to glibc source again (death)
hmmmmmmm
it looks like glibc tries to mmap something to elf file
probably issue is what i dont support MAP_FIXED and my alloc for fixed address is shit
tomorrow ill fix this
inner oak
i need to move all process memory to virtual contiguous, i used buddy for process stack and elf but this is dumb
inner oak
added some progress bar to initrd loading
quiet dome
added some progress bar to initrd loading
me when slow initrd loading:
inner oak
me when slow initrd loading:
what
inner oak
imagine needing a progress bar for initrd loading cuz its that slow
i dont have disk loading and this is debian userspace sooo
why not
onyx matrix
imagine needing a progress bar for initrd loading cuz its that slow
he mounts it to tmpfs instead of just yk
inner oak
map_fixed is 90% done
im scared about audio cuz im doing linux compat
(i wanted to do it after linux compat full working userspace)
inner oak
wait its not ub
quiet dome
race condition?
inner oak
i have opinion that i just forgot to reload tlb after MAP_FIXED
in file mmap
(it just copies file to memory)
inner oak
race condition?
its impossible
at least because i running with one cpu and with disabled interrupts in syscalls
quiet dome

so fastfetch fails on gpu detect with some deadlock error (i have no idea) and aborts
anyway ill disable gpu detect with config cuz maybe it just requires sysfs
hollow raft
to get more info from fastfetch for example
Youll probably get top working as well
I'm assuming top uses procfs
But wait how does top work on unices without procfs
inner oak
black magic

was it hard?
inner oak
gcc works
inner oak
time to do epoll
inner oak
you are linux abi comptible right ?
full linux binary compat
sly sandal
full linux binary compat
so this is runnkng with glibc ?
inner oak
yes
inner oak
does dynamic linking work ?
yes

inner oak
if its on debian can it use apt?
yes but i dont have networking
rugged kelp
ah
rugged kelp
wow
inner oak
so i have two issues
bash deadlocks after creating new process if i add support for CLONE_CHILD_SETTID in clone3
and fastfetch/xorg returns EDEADLK too
inner oak
bash deadlocks after creating new process if i add support for CLONE_CHILD_SETTI...
i debugged a bit and it deadlocks in __pthread_rwlock_wrlock_full64
syscall log doesnt give any useful information
maybe its some tid/pid issue
inner oak
im starting orange rewrite
because i want to have support for aarch64 and riscv64 too
and i want to change some stuff which i used a lot too
inner oak
im thinking should i support loongarch64 too
onyx matrix
chinese mips
inner oak
chinese mips
is this yes or no
onyx matrix
you can always add support for it later
inner oak
you can always add support for it later
then ill add it later
anyway i want to support 64 bit arches only
onyx matrix
anyway i want to support 64 bit arches only
i also do this
rugged kelp
because i want to have support for aarch64 and riscv64 too
why tho
rugged kelp
well thats fair
inner oak
and i have raspberry pi so i want to launch orange on it too
rugged kelp
idk but i feel like a rewrite for it is not worth it
inner oak
first ill do pmm and after ill do paging for x86_64, aarch64, riscv64
ill support 5 level paging for x86_64 and 3 level paging for rv64 and 4 level paging for all of them
onyx matrix
being fancy lol
inner oak
being fancy lol
🤫
rugged kelp
why do u want 5 levels of paging
inner oak
why do u want 5 levels of paging
i want to support them if available
rugged kelp
doesnt 4 levels of paging gives you like 128 TB of virtual memory
rugged kelp
well i think we should get 100 levels of paging
so we can have like 1 Googol of virtual memory
inner oak
from old kernel ill copy only buddy allocator and xhci in future
inner oak
buddy is done now i need to do paging for aarch64 and rv64 and i can start making heap and vma
inner oak
paging is done
btw for userspace in future ill use mlibc
because linux compat is not fun ❌
inner oak
so
i need to make timer drivers for riscv64 and aarch64
for x86_64 ill use hpet and tsc
inner oak
how aarch64 and riscv64 interrupts are work
i want to do now interrupts and after disk drivers
for nvme ahci and virtio
or only nvme and ahci
nvme cuz why not
and ahci cuz i want to install orange later to my laptop
onyx matrix
how aarch64 and riscv64 interrupts are work
pain
inner oak
is this even good idea to use naked for interrupt handlers
inner oak
orange candy

orange os so popular they named a fruit after it
yes
rugged kelp
orange os so popular they named a fruit after it

inner oak
time to do x2apic
inner oak
i want to do linux like files struct
like
having one file for one function for userspace for example
solid hearth
having one file for one function for userspace for example
syscalls?
quiet dome
yes
inner oak
aarch64 interrupts
inner oak
wait wtf
how did it not started to spam with page faults
when i forgot to change stack from uefi for exception handlers
maybe
maybe
my tlb flush is broken
onyx matrix
very probably
inner oak
my tlb flush is broken
it was some paging stuff which i fixed
also it was selecting uefi stack because i didnt setup sp_el1
time to do riscv64 interrupts
inner oak
actually riscv64 interrupts are the most simple
inner oak
im too lazy to do riscv64 stuff so ill port it later
for now my target is x86_64 and aarch64 cuz i have hw only for them
onyx matrix
x3apic

inner oak
i need to do scheduling before disk drivers because i want to always use poll way instead of interrupts

Why not interrupts? You will just sched_yield() on a loop?

okay okay ill do interrupts 😭
but later
so my todo is:
- scheduling
- disk/vfs/ext2
- userspace and also working on networking

Intel® Simics®
i wish it will say about some bugs in my code
cuz my xhci worked half on my friend pc and on ilobilo laptop it didn't work at all
inner oak
tbh its really scary to launch orange on my hw with nvme driver
inner oak
nvme works
(yes i just writed first lba with limine.conf)
now im going to sleep
tomorrow ill make it lockless
and ill add write and flush operations

is there vm that doesn't forgives
inner oak
but more forgiving than some (or most) real hardware
even my hw more forgiving than vbox 😭
icy nova
even my hw more forgiving than vbox 😭
that means vbox is based

inner oak
should i target gpt only or mbr and gpt both
inner oak
Its not that complicated
k
onyx matrix
should i target gpt only or mbr and gpt both
I have none xD
inner oak
raw ?
quiet dome
lol
inner oak
mbr and gpt parsing is done
my goals are now get ext2 and fat32 and also get ahci and virtio disk
inner oak
also i want to do sysfs and devfs after disk loading
sysfs because some stuff in linux requires it
inner oak
instead of path vfs ill do vfs with vnodes
like if some process will open some file filesystem should fill vnode struct in fd struct
final pilot
like if some process will open some file filesystem should fill vnode struct in ...
wait what were you doing before then
inner oak
wait what were you doing before then
i used pathes
like there's function in vfs for example read and i need to pass path to it
but this is terrible so i dont want to do it anymore
inner oak
time to do good mutex implementation
because i want to keep enabled interrupts in kernel and i need some yielding lock
inner oak
ill do pvclock now to get more accurate score
inner oak
inner oak
fuck arch linux
today i wanted to upgrade gcc and i have no idea why but libstdc and libgcc were removed
now i am xubuntu user
narrow mesa
yeah in my experience arch linux always fucks itself up after a few updates
or if u dont update it for a few weeks and try updating it again it just explodes
onyx matrix
today i wanted to upgrade gcc and i have no idea why but libstdc and libgcc were...
arch moment
inner oak
ext2 get inode works nice
inner oak
maybe it will be good to add support for 64 bit
inner oak
what if i try to support ext4 too
quiet dome
what if i try to support ext4 too
the end of times will happen
inner oak
the end of times will happen
ill try to support it but only read only
extents are bit pita
quiet dome
extents seem cool idk
narrow mesa
getting blocks from ext2 node is done
Why does it have 4 links
inner oak
Why does it have 4 links
., .., and some two files
jaunty oxide
files don't reference the directory
narrow mesa
^
narrow mesa
And
quiet dome
the inode2 has four links
quiet dome
files don't reference the directory
iirc they do
narrow mesa
the inode2 has four links
Which
quiet dome
. .. and the two files
narrow mesa
Lol
quiet dome
huh wait
only the . and .. entries reference the directory
I just did a test on a clean directory
inner oak
narrow mesa
but creating a subdirectory references the parent directory
Because .. References parent I guess
jaunty oxide
oh lost+found might be referencing it as well
inner oak
i forgot about it
quiet dome
But wait that explains only 3 links
then he has 2 subdirectories ig
inner oak
test1 is directory too
quiet dome
why doesnt he just ls the root of the thing lol
inner oak
dont blame me
quiet dome
why doesnt he just ls the root of the thing lol
so we see it for ourselves
narrow mesa
So u have two directories in root or what
jaunty oxide
yeah
inner oak
yes
narrow mesa
Oh
inner oak
read work
final pilot
meow meo wew ewmeow meow meow
inner oak
ls and write is done
for ls im using getdents way
because its more optimized and cool
inner oak
i need to change my block allocator to more contiguous
cuz i need contigious blocks for extents
journaling looks to me bit useless so i will not support it
inner oak
ext4 read
inner oak
okay so im bit lazy to do write
so ill left this for future
when ill want to do self hosting
for now read is done so i can do disk loading now
time to do ustar
tmpfs, devfs with sysfs
also now ill start fixing gpt
all this time i was testing with mbr
inner oak
okay so im bit lazy to do write
or ill do write only for ext2 and fat32 (when i implement it)
rugged kelp
what the hell does lost+found evne do tho
jaunty oxide
orphaned inodes get put in there by fsck
inner oak
im sick but i need to end vfs
and i still thinking about userspace
should i do linux compat or mlibc idk
sharp coral
https://tenor.com/view/buzz-lightyear-gif-21327280
Mlibc + unix like + limine
inner oak
i dont want competition
relaxxx
jaunty oxide
should i do linux compat or mlibc idk
the cool kids do mlibc
inner oak
the cool kids do mlibc
im cool kid
inner oak
best bg
inner oak
in my userspace i want to implement everything that userspace requires
without stubbing
inner oak
uhhhh
today i fell very hard
my knees are bleeding so no orange today
cuz of pain
so ill play ultrakil
quiet dome
ibuprofen
narrow mesa
hospial
white bramble
onyx matrix
cuz no electricity
mfw
inner oak
bruh all this time i was trying to init ghost port on vbox 💀
like
there's 0-13 ports
i was trying to init port 14
velvet nebula
no i meant, did you make an oopsise?
velvet nebula
f
inner oak
i understood this when i typed info xhci in vbox debugger and saw this
there's no port 0
velvet nebula
bruh
inner oak
i have no idea why i cant get descriptors from usb device in vbox
set addr is successful
ill look to other xhci drivers
seabios have nice src
quiet dome
who doesnt
inner oak
i have no idea why i cant get descriptors from usb device in vbox
interesting im getting short packet error on some hw
maybe issue is in speed
inner oak
i want glibc so much
onyx matrix
what a background
narrow mesa
Lol
inner oak
what a background
do yall like old bg with orange more this
onyx matrix
yes
onyx matrix
perfect
inner oak
time to sysfs
rugged kelp
wait are you already gonna run xorg wtf
inner oak
wait are you already gonna run xorg wtf
im implementing some stuff which it requires
now im doing elf loading
inner oak
idk should i build own userspace or just use something like debootstrap
narrow mesa
Linux compat
narrow mesa
Why would you build it then
jaunty oxide
Void linux
inner oak
okay im going to use fedora
inner oak
time to do syscalls
i hate that linux have arch specific syscall tables
i wrote some cmdline parser
for example for hw where acpi is broken
at least elf loading works
my target is implement everything
even rseq or brk...
narrow mesa
bootstrap allocator for userspace
inner oak
finally
my reddit account now is not under shadow ban
it means i can post to r/osdev now
and get a lot of github stars 🤑
🤑🤑🤑
inner oak
something is broken in elf loading
they are not broken
ig issue in auxv
i accidentally put stack to elf file
inner oak
i ported bash again
with linux compat it was pain cuz of pselect (i used astral converter to poll)
narrow mesa
Now unport it and then report
narrow mesa
with linux compat it was pain cuz of pselect (i used astral converter to poll)
Are u doing Linux compat now?
solid hearth
paging is for the weak
inner oak
time to fix some race conditions
spamton means panic
and it triple faults
with >1 cpu
bruh 💀
inner oak
okay uhhhhhh
i spent this day
on fixing some dumb bug
glibc deadlocked somewhere and issue was that i forgot to return current tid in set_tid_address
inner oak
bash works on real hw
inner oak
oh yes i have fucking ub which i can get only with 0,0001% chance
or its my usb stick corruption
inner oak
i got first stack overflow in my life
my syscall stack is 32kb
and when there's some path operation really bad things happen
(i had ~12 path buffers when my poor stack can contain only 7)
also i got 1k karma on reddit 💀
inner oak

inner oak
i was doing byte offset to uint64_t* array
vast lake
i was doing byte offset to uint64_t* array
finally
inner oak
what requires
if i wont get some dumb bugs i have chance to run kde like fishix
for xorg i need to finish unix sockets
inner oak
nvm about gcc my target is get some init
maybe systemd
it requires sys_mount so time for sys_mount
inner oak
i forgot that i still dont have unix sockets
inner oak
it looks like stack is not changed after yield
found issue
i used bottom of scheduling stack instead of top
inner oak
gcc works
narrow mesa
why tf is everyone doing linux abi now
because distro maintenance is kinda boring
solid hearth
I might do a fishix for that
I don't want to build the whole userspace and maintain it
jaunty oxide
why tf is everyone doing linux abi now
Its easier to rush userspace stuff to get to kde in 1 second and then give up because the kernel doesnt work
I feel like having to put in effort in usespace ports gives you a bigger incentive to work on the kernel believe it or not
inner oak
linux abi?
yes
inner oak
why tf is everyone doing linux abi now
i want to get userspace working without building everything
after getting userspace working maybe ill switch to mlibc or write own libc because linux compat is boring
inner oak
guess what
chicken butt
i already got some kind of working userspace so time for mlibc ig
inner oak
im gonna use jinx
narrow mesa
Just use the Linux sysdeps? Lol
inner oak
Just use the Linux sysdeps? Lol
i forgot about this
but im no longer linux compat and i want to have my syscall table
narrow mesa
but im no longer linux compat and i want to have my syscall table
Why
quiet dome
what i like about having to do distro dev is that u can procrastinate it until kernel dev gets so annoying it gives u a complex partial seizure
so u do distro dev
and then when that gets so annoying u start having a mental breakdown
u go back to kernel dev
(and the cycle of agony repeats)
solid hearth
lol
inner oak
im wrtiing own python build system instead of jinx
inner oak
finally i built toolchain
i had some issues with automake so i was updating binutils build stuff manually with libtoolize and autoconf
inner oak
my honest reaction when local variable turns into trash cuz of stack corruption
inner oak
im fixing signals rn
inner oak
i wasted 2 hours of my life because i forgot about stack alignment
inner oak
time to port xorg
inner oak
now im using evalyn's gz decompressor to load initrd
solid hearth
why not the one in limine
inner oak
i can not worry about fat asf initrd anymore
inner oak
inner oak
fd pass and ucred pass in recvmsg is done
im doing them now to not care about them in future
inner oak
link() is done
final pilot
nice
inner oak
unlink is implemented properly now too
jaunty oxide
@inner oak since you're doing evdev you might be interested in my xorg-server patches for evdev bullshit
basically it just adds a new evdev backend that allows it to automatically enumerate all /dev/input/event* devices and pass it to the evdev driver
I think it'll be upstream to the astral repo by tomorrow
not sure
jaunty oxide
basically it just adds a new evdev backend that allows it to automatically enume...
instead of having to manually add the devices in xorg.conf
inner oak
instead of having to manually add the devices in xorg.conf
ill use it because i didnt implemented getting event device by name
inner oak
guess what
chicken butt
i hate autotools
tf they cant make one thing work on other versions too
why i must doing autoreconf and after get some dumb errors
inner oak
meow meow meow meow
inner oak
time to port xeyes and implement some sysdeps
im going to use libudev-zero
for xf86 input evdev
inner oak
i have some issue
my rel y is broken
i have no idea how to fix
anyway im going to use own input stuff instead of evdev
i dont want to waste time on this
velvet nebula
nah, port steam
inner oak
uh nuh
velvet nebula
XD
inner oak
i want to port glxgears xeyes and some terminal
and gtk too
with it i can make orange more driveable
jaunty oxide
os-test:
inner oak
wtf
how did my nvme driver broke on real hw
anyway ill rewrite all my disk stuff cuz it bit sucks
vast lake
i built glib and cairo
cool
inner oak
i love that gnome have mirrors on github
inner oak
i have 3 issues rn
my page table destroy is trash
vmm unmap doesnt free some stuff allocated with kheap
glxgears output is lagging (but it shows 900 fps without optimizations)
inner oak
vmm unmap doesnt free some stuff allocated with kheap
fixed
issue was that heap didnt used freed memory
inner oak
glxgears output is lagging (but it shows 900 fps without optimizations)
maybe its some timekeeping issue
inner oak
glxgears output is lagging (but it shows 900 fps without optimizations)
fixed
and i fixed some race condition with futexes
inner oak
my page table destroy is trash
fixed
i was freeing kernel page tables instead of user
for heap maybe ill port some
