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 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.

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 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 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.

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 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.
