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 781cc78a1f BuildSystem: Fix header copying to sysroot
We used to copy all headers everytime to sysroot which caused
rebuild of the whole os. Now we use the cmake command
'copy_directory_if_different' which seemed to fix this issue :)

Bananymous 2a8dc58b6a BuildSystem: Cleanup cmake code
The buildsystem is kind of a mess. I will be writingn build
instructions soon.

Bananymous 8a8793fd2d BuildSystem: you can now build the toolchain with cmake 2023-04-06 00:23:02 +03:00
Bananymous 7f95444bb5 Kernel: Start work on making tty a file
TTY is now a file that you can read from/write to. I still have
to port shell to use this new interface

Bananymous dffdb51713 BuildSystem: remove non-existent file from kernel CMakeLists.txt 2023-04-03 19:02:25 +03:00
Bananymous 46d65471d9 Kernel: ATA now uses irqs instead of polling
Reading is now much slower at ~500 kB/s it was around 3 MB/s.
This is probably mostly due semaphore blocking taking atleast
until next reschedule (1 ms itervals). This will be a problem
as long as we are using only single processor.

I could try to use {READ/WRITE}_MULTIPLE commands, but since
most of the disk reads are 2 sectors (inode block size) this
will at most double the speed.

Most efficient speed up would of course be caching disk access
data and inodes overall.

Bananymous dcc174b62e Kernel: Move ATADevice to its own file from ATAController
The API is kinda weird since device reads/writes go from
ATADevice -> ATAController -> ATADevice
but this is for now atleast necessary since ATAController has(?)
to keep all devices from using the disks at the same time

Bananymous 2aad357c18 BuildSystem: building for 32-bit works now 2023-04-02 05:03:17 +03:00
Bananymous 4c5176f751 BuildSystem: We are now using cmake instead of plain make
I have been annoyed for a while since I had to build everything
when running the os since the buildsystem was really bad.

I wanted to rewrite the whole build system and changed to using cmake

:)
