Bananymous 24d91eee90 Kernel/LibInput: Rework Joystick handling 
Joystick axis and buttons are now named to standard values, this allows
interfacing multiple different controllers (only DS3 is supported)

Add ioctl calls for userspace to set joystick player leds and rumble

Only use DS3 code paths when we detect that the attached device is
actually an DS3 controller

update test-joystick program to the new interface and add support to
control rumble and player leds

Bananymous 8f1b314802 Kernel: Add ioctls to select audio device's output pin 2026-01-06 22:26:11 +02:00
Bananymous da6794c8ce Kernel: Implement HD audio driver 
This is very basic and does not support a lot of stuff (like changing
the output pin :D)

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

Bananymous 65664b0d65 Kernel: Add support for DualShock 3 controllers 
This driver accepts any HID joystick devices but button and axis
mappings will only work on a PS3 controller

Bananymous 08bfa0971e Kernel: Rework storage device and disk cache locking 
Syncing the disk cache no longer blocks the underlying storage device
and the disk cache itself during sync

Bananymous 912c5ea0bf Kernel: Implement basic RWLock 2026-01-02 17:50:22 +02:00
Bananymous 6cdf5a5a7f Kernel: Make AHCI controller thread safe 2026-01-02 17:50:22 +02:00
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

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

Bananymous 31a1968798 Kernel: Cleanup scheduling while idling 
If there are no threads in the run queue and we are idle, attempt to
wake up threads from the sleep queue

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

Bananymous 9d0990e5e8 Kernel: Implement /proc/<n>/fd 2025-11-24 00:19:51 +02:00

Bananymous 05d59a05df Kernel: Remove obsolete kprint 
This hasn't been in use in 3 years :)
 2025-11-22 06:21:50 +02:00
Bananymous fff5139d80 Kernel: Add /proc/<n>/cwd 
Also update /proc/<n>/* permissions to match what linux does :D

Bananymous d60f12d3b8 Kernel: Add support for SCM_CREDENTIALS and fix recvmsg 
recvmsg was broken when receiving into more than a single iovec

Bananymous dd636ffcb2 Kernel: Add support for SA_SIGINFO 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

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

Bananymous 89c0ff1a9d Kernel/LibC: Replace SYS_{GET,SET}_TLS with SYS_{SET,GET}_{FS,GS}BASE 
This allows userspace to use both registers
 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 f1d12c330e Kernel/LibC: Implement MMAP_FIXED_NOREPLACE 
This is a handy thing from linux

Also fix MMAP_FIXED validation and error reporting

Bananymous 72982e3c2b Kernel/LibC: Take fcntl extra field as uintptr_t 
This allows passing pointers to fcntl
 2025-11-10 01:40:33 +02:00
Bananymous 04d24bce70 Kernel/LibC: Implement {recv,send}msg as syscalls 
This also removes the now old recvfrom and sendto syscalls. These are
now implemented as wrappers around recvmsg and sendmsg.

Also replace unnecessary spinlocks from unix socket with mutexes
 2025-11-10 01:40:33 +02:00
Bananymous 7367672570 Kernel: Default initialize flock as unlocked 
This caused unlocked flock's to hang on lock
 2025-11-02 21:10:13 +02:00
Bananymous 5f61581e1d Kernel: Show QR code with panic logs on kernel panic

Bananymous 30215963b2 Kernel: Fix /proc/<pid>/exe permissions 2025-08-29 01:40:56 +03:00
Bananymous 391fc0c4c2 Kernel: Don't crash if Ext2 filesystem doing too many fileops 
I had a hardlimit of 10 block buffers and if they ran out, the kernel
would crash. this patchs increases the number of buffers to 16 and
removes the crash condition when they run out :D

Bananymous f926e599fa Kernel: Zero initialize Processors 
This moves processor array to .bss reducing data size by 8192 bytes :)

This needed GCC updated to 15.2.0 because of an internal compiler error
I found :)

Bananymous 9a6eae69ba Kernel: Replace all occurances of BSB with BSP 2025-08-25 17:11:32 +03:00
Bananymous 350ae90bb6 Kernel: Make all futexes shared 
Some stuff tries to use shared futexes so make them all shared. Private
futexes would be faster as they are process specific but supporting both
would need some reworks

Bananymous c07188a60e Kernel: Look for PS/2 devices in the ACPI namespace 
This allows finding the PS/2 controller on newer machines that don't
have the 8042 bit set in FADT.
