Bananymous 511ab7e99c LibC: Define locale_t as an poiter

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

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 3ee6240806 Kernel: Prioritize EEXISTS sys_mkdir 
This fixes `mkdir -p ...` failing to create existing parents which are
not writable

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`

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

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 bcf1c6d110 BAN: Add print formatter for Span 2026-07-07 04:53:41 +03:00
Bananymous b62687f5e7 LibC: Cleanup backtrace code 2026-07-07 04:44:44 +03:00
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`

Bananymous ea4e016b1e DynamicLoader: Fix TLS memory initialization 
I was reading the TLS data before performing relocations so any TLS
variables pointing to relocated objects would not get the correct data

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 :^)
