Bananymous 48eca3d031 LibC: Make libc usable with tcc 
tcc does not provide its own stdint.h but defines everything in
stddef.h. Also tcc does not support [[noreturn]] attribute syntax.

Bananymous cbe3f2a4ac BuildSystem: Cleanup and fix cmake files 
I now set library SONAME so i don't have to build them in build root.

Creating font now makes sure the install directory exists. This allows
building using make files.

LibC now links agains ligcc

Bananymous caa8c1da90 LibC: Add stub implementations for set{rlimit,priority} 2025-01-25 18:15:50 +02:00
Bananymous 60bffb5f49 LibC: Implement `clock` in terms of `clock_gettime` 
This allows clock to "just work" after I update clock_gettime to support
CLOCK_PROCESS_CPUTIME_ID.

Bananymous c6cd185cb5 DynamicLoader: Fix copy relocations 
Weak symbols are now actually resolved to the same strong symbol between
shared objects and copy relocations now work!
 2025-01-24 19:23:33 +02:00

Bananymous 766b8cd62e LibC: Fix stdio FILE operations 
Mixing read/write/ungetc was broken. This mostly fixes everything. There
might still be some problems that have to be fixed
 2025-01-16 14:57:58 +02:00
Bananymous 72059a9441 LibC: Redefine SEEK_* macros to match common systems 
some ports written in assembly seem to depend on this
 2025-01-14 22:52:13 +02:00
Bananymous ebecbb69ec LibC: Implement some mem* and str* functions in assembly 
This made them a lot faster on modern cpus with optimized rep stos and
rep movs
 2025-01-14 22:50:46 +02:00
Bananymous 14c70c5cc8 LibC: Make mem* and str* functions weak symbols

providing an general implementation
 2025-01-14 18:36:54 +02:00
Bananymous d62a67502e LibC: Remove global -fno-tree-loop-distribute-patterns flag 
This is only really needed for string.cpp where mem* and str* functions
are defined
 2025-01-14 18:35:33 +02:00
Bananymous 4b2c303873 LibC: Add weak_alias header that defines a weak_alias macro 2025-01-14 18:33:57 +02:00
Bananymous 8c45249c06 LibC: Remove stdint.h as toolchain provides one 
I have no idea why i even had this written, it was just containing
compiler macros

Bananymous 55c8a15983 aoc2024: Implement day25 solution 
This was a nice AOC season. First time I fully completed it! I may still
optimize my solutions as some of them are a bit slow...
 2024-12-25 18:13:57 +02:00
Bananymous 3607e2e759 aoc2024: Implement day24 solution 
This is kinda weird and specific to my input but it works xD
 2024-12-25 18:13:20 +02:00
Bananymous d035068982 aoc2024: Implement day23 solution 
I'm not proud of my implementation to last 2 days, but they work in a
reasonable time. I might optimize them later...

Problem is largely with my hash structures. Preallocating a lot of
elements before running day22 makes it run in less than half of the
current time.
 2024-12-23 21:20:47 +02:00

If battery reports its full capacity as zero, battery percentage
calculation did a division by zero crashing the TaskBar :)
 2024-12-18 18:36:26 +02:00

Bananymous 3e36834751 aoc2024: Implement day10 solution 2024-12-10 17:26:39 +02:00
Bananymous 581caff638 BuildSystem: Install base sysroot only once 
Base sysroot is not only installed when creating the syroot directory
for the first time. To get it installed again, you have to either delete
the old sysroot diretory or run clean target

This makes it so its actually possible to edit files specified in the
base sysroot without random hacks.
 2024-12-10 16:44:59 +02:00
Bananymous 8b612ba547 aoc2024: Implement day9 solution 
part2 is kinda unoptimized, it should not use expanded input, but I did
not feel like rewriting my parsing code :)
 2024-12-09 16:20:21 +02:00
Bananymous c4e76b391e aoc2024: Implement day8 solution 
I did not feel like optimizing this one, so its a O(n^2) looking over
every cell in the grid. Performs way faster than my optimized day6
solution tho :DD
 2024-12-08 16:14:39 +02:00
Bananymous cf9ba737f0 aoc2024: Implement day7 solution 2024-12-07 07:34:21 +02:00

Bananymous 415b20f884 LibC: Remove errno EEXISTS 
I don't know why I had added this. It doesn't seem to be a thing on
either POSIX or linux. This was literally equivalent to EXIST

Bananymous f985673dc3 LibGUI: Add API to retrieve Window's underlying framebuffer 2024-11-27 13:29:42 +02:00
Bananymous aaff5a65e1 Kernel/init: /dev/tty is now custom symlink to controlling terminal 
kernel now passes the name of default console to init process so init
knows which file to open as stdio. before /dev/tty was referencing the
system wide current terminal which was inherited from cmdline. This
doesn't work anymore as we have pseudo terminals implemented that can
chage the current terminal during runtime :D
 2024-11-17 22:38:52 +02:00
Bananymous 36d07065fb WindowServer: Optimize msync calls to synchronize less bytes 
This *probably* makes framebuffer much faster :D Window server does not
have to do page aligned and page sized syncs which used way too many
pixels.
 2024-11-17 20:15:28 +02:00
Bananymous 411f32c766 WindowServer: Make select timeout more precise to hit target FPS 
Previously window server was only running at around 40 FPS while
targetting 60. This makes the select timeout properly sleep so that
target FPS is reached!

their attributes.
 2024-11-14 20:57:34 +02:00
Bananymous bda2c663da WindowServer: Implement fullscreen windows

scaled to framebuffer using nearest sampling for best performance.
 2024-11-13 19:10:15 +02:00
Bananymous 5e041e6e5a WindowServer: Make all terminating signals exit cleanly

server crashes on page fault or some other unexpected exception.
 2024-11-13 17:32:13 +02:00
Bananymous d19264eea8 WindowServer: Implement partial window resizing 
This patch adds support for client side resizing, so clients can request
the server to resize their windows. WindowServer will respond with
resize event when and if the resizing is complete.

non-focusable.
 2024-11-08 02:55:10 +02:00
Bananymous 12bc7480e0 LibC: Implement _Exit 
This just calls _exit as POSIX says they can be equivalent
 2024-11-08 02:52:12 +02:00
Bananymous 92862fdf39 LibC: Implement nan{,f,l} as functions 
One port was using function pointers to these functions so macros don't
work.

Bananymous a356d90445 LibC: Fix libc compilation for 32 bit target 2024-11-04 10:51:31 +02:00
Bananymous f4be37700f Kernel/userspace: rework floating point math 
SSE is now unconditionally enabled any where and most of math.h is now
actually implemented. using __builtin_<func> lead to many hangs where
the builtin function would just call itself.

 2024-10-13 22:01:46 +03:00
Bananymous 8adc97980a Shell: rewrite the whole shell to use tokens instead of raw strings 
tab completion is still running with raw strings and that has to be
fixed in the future.
 2024-10-13 22:00:16 +03:00
Bananymous 3e68981b0b userspace: Remove start-gui from shell builtins and make it an alias

executable reinitializing it later :D
 2024-09-24 17:56:12 +03:00
Bananymous 1b0086217c Terminal: Do scrolling in putchar if necessary 
I overlooked that handling *newline* scrolls would be enough. You can
definitely scroll more if printing a lot of text which wraps to the next
line.
 2024-09-23 15:00:47 +03:00
Bananymous 1280528e4e BuildSystem: Use -O2 for all libraries 
I don't know why I had not specified optimization level for libraries.
Only LibImage was using explicit -O3. LibImage doesn't need O3 anymore
as O2 seems to be around the same speed.

time for current process nor children

Bananymous d88ee5c9ee Kernel/LibC: Implement `creat` with `open`

Bananymous a084f83f4c Kernel: Rework kernel-side ELF loading 
ELFs are now loaded as MemoryRegions so they don't need special handling
anywhere. This also allows file backed COW optimizations to work. This
was not the case before.

This patch removes now obsolete LoadableELF and unused ELF files from
LibElf.
 2024-09-15 23:57:34 +03:00
Bananymous 1a24d1839f LibInput: KeyEvent to ansi string now handles delete key 
This allows Terminal emulator to also handle delete key.

The value of `\0x7F` may be wrong as qemu's serial console seems to be
sending `\e[3~`

Bananymous c3040a04a3 Terminal: Optimize printing a lot 
Terminal used to run `yes` at around 400 lines per second

This patch pumps that to over 100'000 lines per second!

There are 2 optimizations done:
  1. only invalidate window once after rendering is done
  2. if printing more than `rows()` newlines skip prior data
