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
 2024-01-12 02:55:06 +02:00
Bananymous 8e31ab2de8 BuildSystem: clean target now deletes disk image 2024-01-11 13:27:02 +02:00
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 d2c0718f7d Kernel: Fix toggleable modifier keys and add two more keys 2024-01-11 11:43:05 +02:00

Bananymous ab39c6541a Kernel: Require keymap loading superuser privileges 2024-01-10 14:50:30 +02:00

Bananymous 8f89519bcf Kernel: Keymaps can now be loaded from files 2024-01-10 14:43:19 +02:00
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 e8f853a197 Kernel: After device updates, reschedule instead of sleeping 2024-01-09 11:21:00 +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.
 2024-01-08 10:50:55 +02:00
Bananymous 2fec718590 Bootloader: cleanup code 2024-01-08 10:50:55 +02:00

Bananymous 40f55be587 Userspace: Write simple mouse test program 
This program draws circle on framebuffer, that you can move with
mouse, resize with scroll, and recolor with mouse buttons.
 2024-01-04 19:50:26 +02:00
Bananymous 54c811ac2e Kernel: Fix some mouse scrolling bugs and cleanup event generation 2024-01-04 19:50:26 +02:00
Bananymous 12a78c822e Kernel: Explicitly construct ByteSpan from Span<uint8_t> 
VSC complains about not finding proper constructor, this fixes that.
 2024-01-04 12:17:55 +02:00
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.
 2024-01-04 12:17:55 +02:00
Bananymous d1e187570e Kernel: Fix old keyboard command 2024-01-04 12:08:23 +02:00
Bananymous d4191c0d94 Kernel: Reorganize PS/2 files to their own directory 2024-01-04 12:04:45 +02:00

Bananymous 891ced4da2 Kernel: Move PS2Device to its own file 2024-01-04 12:04:45 +02:00
Bananymous 8f8d6bddc0 Kernel: Unify PS2Device to handle commands instead of inherited 2024-01-04 12:04:45 +02:00
Bananymous d2d12d5281 Kernel: validate_{string,pointer}_access now return ErrorOr<void> 
Now that signals are only processed when returning to userspace,
address validation has to do an early return.

Bananymous 0ba278041b Kernel: Start exec by loading the ELF file. It might not exist... 2024-01-03 23:50:02 +02:00
Bananymous ccaa159a73 Bootloader: Add support for ext2 blocks up to 4 KiB 
This should work with blocks bigger than that, but my linux system
only supports up to 4 KiB, so I cannot test this.

This allows getting rid of forced block size in mkfs and let the
program select appropriately sized blocks.

Bananymous 7356a83a44 Bootloader: Optimize some unnecessary branches on carry add/sub 2024-01-03 17:05:33 +02:00
Bananymous 2a68df81e2 Bootloader: Fix bootloader on bochs 
Bochs int 0x10 seems to scrap full ebp and top bits in some
registers. I now save all 32-bit registers on call frame. Also
ebp is across all int 0x10 calls.
 2024-01-03 13:09:55 +02:00
Bananymous 50ca2ac09e Bootloader: Interpret 0x7F (DEL) as backspace 
This allows backspace to work over qemu's serial connection
 2024-01-03 11:58:50 +02:00
Bananymous b0ff2392a1 Kernel: Add some helpful debug prints 
Log RIP when stack pointer is out of bounds.

Log all syscalls that return ENOTSUP
 2024-01-03 02:08:01 +02:00
Bananymous 001e95f973 Kernel: Optimize sse saving/loading 
Only save and load sse when new thread is trying to execute sse
instruction. There is no need to do that every time we enter kernel.

Bananymous db0650cf10 LibC: Implement basic atexit. This allows clean exit from doom (soon) 2024-01-03 00:30:37 +02:00

Bananymous d2bc399770 BAN: Make StringView::split const and fix bug with empties 2024-01-03 00:14:29 +02:00
Bananymous 1bd33e76e5 cat/cat-mmap: print newline if file doesn't end in one 2024-01-02 23:27:13 +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 96d831c31a Kernel/LibC/Userspace: Implement chown and set tty owner on login 2024-01-02 22:19:38 +02:00
