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

wikipedia about RB trees.

to be sure

search files though :^)

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 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

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 7b4b5a3440 BAN: Cleanup intro_sort and quick_sort 
Only recurse to the smaller partition. This prevents worst case O(n)
recursion

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!

Bananymous e78fcf63b6 ports: Update mesa 25.0.7->26.1.4

version where it was supported. Seems to work fine though
