Bananymous e7d644b874 AudioServer: Fix rounding the number of samples when resampling 
If client tried to play a single sample at lower frequency as the

this

character set
 2025-11-17 05:26:07 +02:00
Bananymous dc0fa49de2 ports/tuxracer: Add sound support and fix compiling 2025-11-17 05:26:07 +02:00

server :D
 2025-11-17 05:26:07 +02:00
Bananymous f166cb09ec Kernel: Fail xHCI initialization if page size != 4096 
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} 
This allows programs to dump better backtraces on crashes compared to
what kernel can as libc can resolve symbols and libraries' dynamic bases
 2025-11-17 05:26:07 +02:00
Bananymous dd636ffcb2 Kernel: Add support for SA_SIGINFO 2025-11-17 05:26:07 +02:00

 2025-11-17 05:26:07 +02:00
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
 2025-11-17 05:26:07 +02:00
Bananymous c700d9f714 Kernel: Implement connect for UDP socket 2025-11-17 05:26:07 +02:00

This is not required by posix but some ports use it
 2025-11-17 05:26:07 +02:00
Bananymous 6f8d850726 BuildSystem: Cleanup port building script 
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

Replace MAP_FIXED with MAP_FIXED_NOREPLACE and only attempt to map
program headers with PT_LOAD
 2025-11-13 04:20:53 +02:00
Bananymous 9537922acc Kernel: Implement proper memory region splitting 
Memory regions are now splitted when they get munmapped, mprotected, or
mmapped with MAP_FIXED. This is used by couple of ports, and without
this we were just leaking up memory or straight up crashing programs.
 2025-11-13 04:20:53 +02:00
Bananymous a39aa73e21 Kernel: Allow munmap on non-page aligned address 2025-11-12 00:06:36 +02:00

Bananymous 04d24bce70 Kernel/LibC: Implement {recv,send}msg as syscalls 
This also removes the now old recvfrom and sendto syscalls. These are

Also replace unnecessary spinlocks from unix socket with mutexes
 2025-11-10 01:40:33 +02:00
Bananymous 2f38306c6b LibC: Implement simple posix_spawn{,p}
