Bananymous 130c4f681c ports/ncurses: Enable widec support and disable test compilation 
There is one test with buggy macros that does not compile and im not
feeling like making a patch for it now :^)

Bananymous e03a26cf01 LibC: Don't ASSERT in times 
Return the current process CPU time as user time. We don't have a way to
get system/user time separation or CPU times of child processes
 2026-07-20 04:07:23 +03:00
Bananymous 2a3eca5b36 LibC: Implement POSIX binary search trees 
I used RB tree for this. The implementation is based on the code on
wikipedia about RB trees.

Bananymous 658e74b507 bootloader: Check that VESA mode is linear 
I don't think there are any graphical non-linear framebuffers but good
to be sure

Bananymous 3148c28c3d userspace: Add basic find utility 
This is mostly working but is missing -exec and -ok support. It can
search files though :^)
 2026-07-08 21:48:14 +03:00
Bananymous fa89645542 userspace: Implement simple sort utility 
This supports most(?) options except for the separate fields. Should
work for simple use cases

Also merge is currently just a wrapper around sort so its not optimized
:D

Bananymous e352bfbb23 mkdir: Don't fail the target exists and -p was given 2026-07-07 16:59:20 +03:00
Bananymous 3ee6240806 Kernel: Prioritize EEXISTS sys_mkdir 
This fixes `mkdir -p ...` failing to create existing parents which are
not writable
 2026-07-07 16:59:20 +03:00
Bananymous 304f94f3b1 LibC: Implement __fpending 
Some gnu programs want this and I don't want to make FILE non-opaque

Bananymous 89fa957297 BuildSystem: Fix keymap in base sysroot 2026-07-07 16:59:20 +03:00
Bananymous 7348511ed3 ports/llvm: Add support for pthread_setname_np and cpu count 
Also package the llvm into the format mesa expects. This was kinda
tedious to always do manually
 2026-07-07 10:30:07 +03:00
Bananymous 20392c6cc1 LibC: Add malloc.h with some GNU extension 
This adds `reallocarray`, `malloc_usable_size`, `mallinfo`, `mallinfo2`
 2026-07-07 10:30:07 +03:00
Bananymous 0843b8989d Kernel: Fix timer deadline issues in scheduler 
Don't wake up threads when getting the next timer deadline.
If we are idling this can: remove thread from block list, get the
deadline for the next blocked thread, return to idle thread. This will
end up sleeping until the next wake up condition which in the worst
case would be rebalance, or indefinitely when not running SMP.

Make sure we always set the next timer deadline. I was not doing that if
the timer interrupt did not lead to a yield
 2026-07-07 10:30:07 +03:00
Bananymous 1c8112f1a7 ports: Update xbanan 2026-07-07 05:07:36 +03:00
Bananymous 49662aa994 Kernel: Don't use peridic interrupts for scheduling 
Scheduler will now set a timer interrupt deadline for when it should get
interrupted next. This fixes a big issue I've had for a long time where
sleeping on an idle core would have to wait for the next periodic
interrupt to wake up. This could cause 1 ms sleeps to be close to 10 ms.

This currently only supports lapic timers and will still fallback to
periodic interrupts when running with PIC. I should add deadline support
to PIT/HPET but why would you run with APIC disabled ;)

Bananymous 7b4b5a3440 BAN: Cleanup intro_sort and quick_sort 
Only recurse to the smaller partition. This prevents worst case O(n)
recursion
 2026-07-07 04:43:06 +03:00
Bananymous 896bb05073 LibC: Cleanup qsort implementation 
Remove random template and just make qsort be a wrapper around qsort_r

Recurse only into the smaller partition. This removes the possibility of
O(n) recursion in the worst case

Use insertion sort for ranges shorter than 16 elements.

Split qsort_swap into qsort_swap_fixed and qsort_swap_general
- fixed one handles 1, 2, 4 and 8 byte elements which can be done directly
with mov instructions
- general copies 64 bytes at a time followed by a single copy for the
  rest. the 64 byte chunk loop gets nicely optimized into sse

Bananymous 97d26b5d4e ports: Split mesa into two packages: osmesa, glx 
Now SDL and other stuff that use opengl dont have to pull X11 libraries

We now also compile glx backend with DRI instead of xlib. This allows
building EGL support as well!
 2026-07-07 04:36:55 +03:00
Bananymous e78fcf63b6 ports: Update mesa 25.0.7->26.1.4 
This required bringing back osmesa code from 25.0.7 which was the last
version where it was supported. Seems to work fine though

Bananymous eee0b7c3ff Kernel: Make ioctl take unsigned long instead of int 
this is what linux does :D

also fix one or two `return ioctl` instead of `return ioctl_impl`
 2026-07-07 03:12:39 +03:00

Bananymous 3e16e69602 LibC: Implement qsort_r 
This is not really required by anything but i've seen few ports
optionally use it if available. This was trivial to implement so why not
add it :^)

I just noticed I had some uncommited patches that are required for the
compilation. Also remove the ifaddrs.h fixup as we now support those!

No need to use SDL2 anymore :^)
 2026-07-04 23:57:00 +03:00
Bananymous 01f0871a83 ports: Add SDL3 port 
I've been planning on doing this for a long time :D This is mostly based
on the SDL2 backend but there are a bunch of fixes

Bananymous ac1fafedcc LibC: Cleanup and fix random functions 
I was getting the size of random state incorrectly and ended up with
double the size user gave us leading to OOB access :D

Also remove hardcoded type -> size mappings and just use a looup table

Bananymous 652e170da9 LibGUI: Ignore failing smo maps in resize event 
This can be caused by sending two back-to-back resize requests. When
handling the first, the server may have already replaced the smo key
with a new one.

Bananymous 63b2284324 Kernel/LibC: support RDTSCP based clock_gettime 
RDTSCP seems to be faster than LSL and it removes the need for getting
the current cpu twice to make sure TSC is read on the correct CPU
 2026-07-03 06:32:04 +03:00
Bananymous 917321eb5f LibC: Wait for thread before returning from pthread_create 
We now make sure the thread starts up and sets its id. There was a race
condition where a process could create a thread and immediately try to
join it. If the thread had not initialized itself the join would fail
with EINVAL as we passed -1 as its id.

Bananymous 0a8b03d349 LibAudio: Make AudioLoaders return float instead of double 
AudioBuffers already use floats internally so there is no need for
loaders to produces doubles

Bananymous 7219eac65f Kernel: Remove unnecessary page table validation 
Processes always have a page table when they are initialized. This was
not true a long time ago when kernel threads could also be processes
 2026-07-02 20:02:24 +03:00
Bananymous 0dc74beb0f Kernel/LibC: Allocate thread stacks in userspace 
This adds support for pthread function for stack manipulation.

Also keep track of main threads stack in the uthread
 2026-07-02 20:02:24 +03:00

Bananymous 6d1696b77e Kernel: Don't allocate userspace stacks in Thread 
Thread only cares about stack's vaddr and size. Stacks are now allocated
before creating the threads.
 2026-07-02 20:02:24 +03:00
Bananymous b19b7f064a LibC: Make pthread_t pointer to uthread instead of a thread id 
This will allow getting info about other threads in userspace!
 2026-07-02 20:02:24 +03:00
Bananymous f449ca8161 Kenrel: Separate pthread API from kernel API 
It didn't really make sense for the syscalls to be named as the pthread
equivalents. Now the kernel just uses thread ids

Bananymous d241975ce1 Kernel: Remove SYS_SLEEP and cleanup SYS_NANOSLEEP 
`sleep` is now implemented in terms of `nanosleep`. `nanosleep` is now
more precise and handles overflow when calculating wakeup time. I don't
think anything was depending on this, but I could see a program sleeping
for max time to block until signal.
 2026-07-02 15:22:52 +03:00
Bananymous 20663b533b Kernel: Rework sleeping API 
instead of sleep_{ns,ms} we now have sleep_{for,until}_{ns,ms}. This
makes code cleaner that just wants to sleep until some timestamp
