Bananymous d970debb4d LibC: Define MAXPATHLEN in sys/param.h 
This file is not POSIX, but some software seems to rely on it
 2026-01-06 21:58:56 +02:00
Bananymous d0ba52073f LibC: Add stubs for shm_* functions 2026-01-06 21:58:56 +02:00
Bananymous 943e3b6f51 LibC: Define IN_CLASS* macros 
These are not POSIX but some software seems to rely on them
 2026-01-06 21:58:56 +02:00
Bananymous 25d43682aa LibC: Bump FOPEN_MAX 16->64 2026-01-06 21:58:56 +02:00
Bananymous ad16de59f8 Kernel: Implement basic F_{GET,SET}LK{,W} 
At the moment these lock the whole file which is not what is supposed to
happen. Some port was trying to use these and this seems to work for
that. This may cause deadlocks but that should be easy enough to find
the reason because of the debug warnings
 2026-01-06 21:58:56 +02:00
Bananymous 8634bbb792 Kernel: Don't save/restore sse or reschedule on spurious interrupts 
I think these should be just fully ignored :D
 2026-01-06 21:58:56 +02:00
Bananymous 60ec5d30fd init: Start Clipboard server on startup 
I had forgotten to commit this when I added the clipboard server :D

Bananymous 4b5a8196c3 Kernel: Fix bitmap byte index calculation in PMM 
No idea how I had not crashed here earlier, but running on real hw with
a bit initrd ended up crashing :D
 2026-01-04 01:16:43 +02:00
Bananymous 706c0816dd Kernel: Move smp_initialized flag after schedulers are initialized 
Before this real hardware failed to boot with smp enabled. Allocating
the idle thread does a page mapping which ends up broadcasting TLB
shootdown to other processes. This ends up failing somewhere halting the
processors never allowing them to initialize their scheduler
 2026-01-03 23:39:07 +02:00
Bananymous a8aa89362d ports/SDL2: Add support for game controllers

mappings will only work on a PS3 controller
 2026-01-03 20:07:08 +02:00
Bananymous 08bfa0971e Kernel: Rework storage device and disk cache locking

and the disk cache itself during sync

Bananymous e26aac3067 Kernel: Decrease the number of syncs done by ext2 inodes 
Each allocated inode used to call sync(). Each sync reads and writes
a block from the filesystem. Doing a 1 MiB write ended up syncing around
257 times
 2026-01-01 23:54:09 +02:00
Bananymous 941e8aa5d5 Kernel: Optimize ext2 filesystem 
block lookup can now also allocate blocks so there is no need to do
multiple lookups of the block did not exist
 2026-01-01 23:15:35 +02:00
Bananymous 33b6536e6b Kernel: Make disk cache entry lookup O(log n) 
I have absolutely no idea why i was doing a linear lookup here :D
 2026-01-01 20:40:38 +02:00
Bananymous 9fbd9288b2 Kernel: Fix symlink deletion from tmpfs 
Small symlinks store their target in inline storage of data block
indices. Freeing blocks did not account for this and tried to interpret
the link target as block inidices to delete
 2026-01-01 20:40:38 +02:00
Bananymous bef1a56007 ports: Update git 2.48.1->2.52.0

Bananymous f06e5d33e7 Kernel: Rework socket binding to an address 
Sockets are no longer bound to an interface, but an ipv4 address. This
allows servers at 0.0.0.0 talk to multiple different interfaces
 2025-12-31 19:28:55 +02:00
Bananymous efdbd1576f ports/SDL2: disable static lib and enable semaphores

Bananymous e7d644b874 AudioServer: Fix rounding the number of samples when resampling 
If client tried to play a single sample at lower frequency as the
kenrel, audio server would never play it leading to the client hanging

This makes calculations round the number of samples always up to fix
this
 2025-12-18 16:05:28 +02:00
Bananymous c64159d5c3 AudioServer: Fix resampling math

Also zero out scratchapd buffers as the spec says
 2025-11-17 05:26:07 +02:00
Bananymous 2dd8b76289 BuildSystem: Automatically delete libtool files 
Half of the ports had a manual post_install step to delete libtool files
this is now done automatically and there is no need for it!

Libtool files have to be deleted as libtool doesn't work while
cross-compiling (at least out of the box)
 2025-11-17 05:26:07 +02:00
Bananymous 2bf7c67767 LibC: Add backtrace signal handlers for SIG{FPE,ILL,BUS,SEGV}

Bananymous dc2a455395 Kernel: Optimize processes' memory management 
Memory regions are now stored in a sorted array. This allows O(nlogn)
lookup for address validation instead of the old linear lookup.

Now inserting new regions is also O(nlogn) instead of the old constant
time, but lookups are **much** more frequent

All dependencies are now installed only ones. If a port depends on for
examle zlib and one of its other dependencies depends on zlib, zlib will
now get installe only once.

Accept .tgz archives as the main download file
