Bananymous 40b626b0aa Kernel: Rewrite all kernel mutexes 
Now SpinLock is actually just a spin lock and I added a Mutex that
does the same as the old "SpinLock". This is in preparation for
starting to support smp and making the kernel smp safe. This commit
also removes obsolete PageTableScope and CriticalScope which should
now be used by alternative APIs.

Bananymous 56a29dc176 Kernel: Fix PS/2 Controller if port 0 is empty 2024-01-13 17:05:29 +02:00
Bananymous db933d5466 Kernel: Improve keymap file loading 
Now you can include other files in keymaps and set which keys are
modifier keys

Only keys that are set in keymap file are actually updated

Bananymous 83ca469ed7 Kernel: Modifier keys are taken from current keyboard layout 
I used to assume where all modifiers were, but they are now taken
from keyboard layout.

Bananymous e6d42e5c45 Kernel: Add timeout for device commands on PS/2 devices 2024-01-10 12:51:24 +02:00
Bananymous 961ab9768a Kernel: KeyEvent is now well known keycode 
Keycodes are easier to handle as you need only one keyboard layout
for keycodes. Otherwise you would need to implement keyboard layout
for every keyboard driver in every language.

Bananymous e4f48cbc73 Kernel: Move PS/2 command queue to controller instead of device 2024-01-09 20:00:19 +02:00
Bananymous d760239748 Kernel: Do a big rewrite of PS/2 code 
Command sending+response reading is now synchronized. This allows
bochs to properly initialize both mouse and keyboard simultaneously.

Also status register is checked EVERY time read/write to other IO
ports is performed.

Bananymous e45b544a39 Kernel: Implement PS/2 mouse driver 
This is realtively simple driver that queries extensions (scroll +
extra buttons) from mouse and reads mouse packages.

Bananymous 8f8d6bddc0 Kernel: Unify PS2Device to handle commands instead of inherited 2024-01-04 12:04:45 +02:00
Bananymous 9fa13079f2 Kernel: Implement supplementary groups 
This code has very ugly file parsing code. I have to create API
for reading files line by line in kernel space...

This allows users to open framebuffer/input files without root.

Mounting has to be moved to userspace soon. It makes no sense to
hard code permissions for every (device) file.

Bananymous 951eac6bfa Kernel: Implement hacky non-block read for ps2 keyboard 2023-12-19 00:20:46 +02:00

Bananymous f3d9da9549 Kernel: Rewrite all read/write functions to use BAN::ByteSpan 
This allows us to not work with raw pointers and use sized containers
for reading and writing.

Bananymous f21d4e794c Kernel: Rework whole ATA driver structure 
Make ATA driver more compatible when we are adding SATA support

Bananymous 27eb5af6f0 Kernel: Rework interrupt mechanism 
All interruptrable classes now inherit from Interruptable which
has methdo handle_irq which is called on a interrupt.

Bananymous 921d95d18f All: Clear lines with only whitspace in them 2023-09-10 00:31:42 +03:00
Bananymous dd9af56e21 Kernel: Start work on making inodes more thread safe 
All inode operations are now locked and thread blocked
 2023-09-10 00:31:42 +03:00
Bananymous 323de3c866 Kernel: Rework whole Terminal structure 
Serial monitors can now be used as a output. This requires editing
init code for the stdio opening. Serial input is not supported, so qemu
still needs graphical window for ps/2 keyboard.

Bananymous c732297623 Kernel: Rename TimerHandler to SystemTimer 
I changed SystemTimer to only handle the "best" supported timer
it can initialize.

Bananymous ca5a097ef5 Kernel: Add function to retrieve boot time as timespec 2023-08-04 16:06:47 +03:00
Bananymous 1f8a5f0ce5 Kernel: F11 now prints current time to debug output 
This allows better timer percision and system freeze checks
 2023-08-04 15:22:51 +03:00
Bananymous 7eb2c140fe Kernel: Move RTC to Timer directory 
PIT ms counter seems to be off by multiple seconds/minute. I will
be probably changing to HPET for system time

Bananymous 659adb89a6 Kernel: Start work on abstracting Timers 2023-08-04 10:29:42 +03:00
Bananymous 9bcfb34524 Kernel: Rewrite whole device structure 
We now have DevFileSystem which is derived from RamFileSystem. All
devices are RamInodes. We don't have separate DeviceManager anymore.
To iterate over devices, you can loop througn every inode in devfs.
 2023-07-10 23:17:14 +03:00
Bananymous aa2aee684b Kernel: remove message from BAN::Error 
We don't store the error message anymore in BAN::Error.
Instead we store a error code that can be mapped into a string.
This allows BAN::Error to only take 4 bytes instead of 128.

We should also make some kernel initialization just panic instead
of returning errors since they are required for succesfull boot
anyway.

Bananymous 62fb233eb1 Kernel: DeviceManager is now a 'FileSystem' so it can expose devices 
Shell reads keyboard through /dev/input :)

Bananymous 426b1482dd Kernel: Fix keymap numlock behaviour 2023-03-29 03:18:22 +03:00
Bananymous fa8e921ee8 Kernel: Rework the whole input system 
We now use Device abstraction that will allow us to provide devices
to userspace through /dev. Currently Shell reads from first and only
device (it being PS/2 Keyboard).
