Bananymous ac5c77ee2c Kernel: Implement USB Keyboard 
This is kinda hacky, as I had disable the PS/2 initialization so that
usb keyboard gets /dev/keyboard0. I should add device hot plugging
support for TTY and GUI...

Bananymous 1efc6a1385 Kernel: Implement simple USB HID driver 
This should be easily expandable to add HID devices
 2024-07-14 02:04:48 +03:00
Bananymous a97a574718 Kernel: Rewrite the whole input system 
PS/2 code is now kind of messed up, but it works. Keyboards and mice are
now an abstract class that is automatically exposed to userspace. This
will make adding USB input much nicer.

Bananymous 14dce1abac Kernel: Start work on USB stack 
Current code can enumerate all xHCI devices and detect their type based
on the class code on device or interface descriptors.

Bananymous 9e1b5cbaab BuildSystem: Cleanup CMake code to allow libc only installation 
There was no way to just install libc which is required for stdlibc++
 2024-06-21 01:45:14 +03:00
Bananymous ad6d95ba52 BuildSystem: Rework the whole cmake build system 
Now files are installed using the install() command instead of manually
copying files to their destinations. This allows automatic recompilation
of headers that did not work previously
 2024-06-19 09:40:03 +03:00
Bananymous 318ce5dec8 All: Fix a lot of compiler warnings from header files 
While reworking build system, header files started to report warnings.
 2024-06-18 23:02:10 +03:00
Bananymous c69919738b BuildSystem: Move all userpace libraries under the userspace directory 
As the number of libraries is increasing, root directory starts to
expand. This adds better organization for libraries
 2024-06-18 13:14:35 +03:00
Bananymous ea7fc7f6c4 Kernel: Implement read-only FAT12/16/32 driver with long name support 
You can now mount FAT filesystems! This code might not work perfectly
but my quick testing seemed to work on all (FAT12/16/32) variants.
 2024-06-14 01:04:12 +03:00
Bananymous 766439db6d Kernel: Start work on adding support for new filesystems 
Old code tried to create ext2 filesystem from all devices.

Bananymous ffacff67cf LibFont: Move PSF code to separate file 2024-06-10 16:10:05 +03:00
Bananymous 0501f3bd99 Kernel: Move font code to its own library LibFont 2024-05-31 10:47:05 +03:00
Bananymous d4d530e6c8 Kernel: Implement basic shared memory objects 
These can allocate memory that can be shared between processes using
a global key. There is currenly no safety checks meaning anyone can
map any shared memory object just by trying to map every possible key.

Bananymous 8bc6c2eb20 Kernel: Move KeyEvent/MouseEvent from kernel to LibInput 2024-05-28 23:30:08 +03:00
Bananymous 06f4b0b29a BAN: Make String and StringView header only 
This allows linking with libc without having to link ban
 2024-05-23 15:43:26 +03:00
Bananymous 693f90449f Kernel: Rework AML package and implement indexing in to packages 2024-04-19 11:26:48 +03:00
Bananymous 89c4abc07a Kernel: Cleanup AML device initialization 
_STA and _INI are now properly called on call devices
 2024-04-12 02:00:30 +03:00
Bananymous 0184e5beb5 Kernel: AML tries to initialize processors when entering ACPI mode 
I had forgotten that Processors used to be a different definition
in AML.

I also implemented reads/writes for FieldElement/IndexFieldElement
that fit in 64 bits. Reads and writes to buffer are still a TODO.
 2024-04-11 01:48:46 +03:00
Bananymous cdbdc1a822 Kernel: Remove lai as a dependecy 
I don't think lai is needed anymore, since my own AML interpreter
can do ACPI poweroff which was all that lai was used for.
 2024-04-10 04:39:48 +03:00
Bananymous b16e65168f Kernel: Rewrite whole AML parser 
Now AML parsing is actually done while respecting namespaces and
scopes. I implemented the minimal functionality to parse qemu's AML.

Next step is to implement AML interpreting and then we can drop lai
as a dependency.

Bananymous e7ef7a9e55 Kernel: Implement barebones AML parser 
This implements only parsing for AML in qemu. InvokeMethods are not
parsed since number of arguments to Methods is not yet known.

Parsing AML uses multiple kilobytes of stack space, so I increased
boot stack size by a lot :D

I am not sure where my own AML is going, but this is good start if
I decide to implement full ACPI on my own.

This code is very much just ugly macro expansion.

Qemu has 2 DefPackage elements that I am not able to parse. Package
data ends while there should be still multiple elements.

Bananymous e0011d22f2 Kernel: Move ACPI to its own directory and namespace 2024-04-04 15:00:13 +03:00
Bananymous 1943c3e7a1 Kernel: Unify IDT and GDT code between x86_64 and x86_32 
The code is pretty much the same, so there are just couple macros
differiating initialization.

Bananymous 99e30a4d7d Kernel: Replace i386 with i686 
I don't really want to be working with i386 since it doesn't support
compare exchange instruction

Bananymous 0424082e7b Kernel: Only compile lai for x86_64 targets 
I will be dropping lai entirely soon. Once I get to writing AML
interpreter.

Bananymous 26ed689d30 Kernel: Remove old GDT, IDT and MMU code from i386 
It will be easier to just rewrite them
 2024-03-22 12:47:34 +02:00
Bananymous f0105cb7fb Kernel: Move Interruptable from InterruptController.h to its own file 2024-03-06 00:47:02 +02:00
Bananymous 418bc54f2b Kernel: Move SpinLock definition to header and fix Scheduler locking 
This patch allows inlining of spinlocks :)
 2024-03-04 22:36:41 +02:00
Bananymous 9c36d7c338 BAN/Kernel: Rework assertion/panic system 
BAN/Assert.h does not need any includes meaning it can be included
anywhere without problems.
 2024-03-04 11:41:54 +02:00
Bananymous 8141b9977d Kernel: Per processor information is now stored in class Processor 
This allows us to allocate processor stacks, and other per processor
structures dynamically in runtime. Giving processor stack to
ap_trampoline feels super hacky, but it works for now.

Bananymous 198dde8365 Kernel: Add klibc for kernel 
Now building same source as libc is not needed and libc doesn't
have to do hacks to allow kernel compilation
 2024-02-14 15:00:04 +02:00

Bananymous 54a92293da Kernel: Implement NVMe driver 
I'm  actually able to boot this os fine on own laptop now!

Bananymous 8f89519bcf Kernel: Keymaps can now be loaded from files 2024-01-10 14:43:19 +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.
 2024-01-10 12:51:24 +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.
