Bananymous e0479b291d Kernel: Move PhysicalRange to its own file and add VirtualRange 2023-05-28 17:48:34 +03:00
Bananymous 812e61ca70 Kernel: Add barebones GeneralAllocator for >4096B 2023-05-08 22:10:49 +03:00
Bananymous 0deda83d05 BuildSystem: linker -O2 doesn't do anything? hopefully 2023-05-06 19:58:08 +03:00
Bananymous ff5bcd4416 Kernel: Add basic fixed width allocator for userspace
We have to move process stacks to the general heap and maybe map
kernel to higher half.

Bananymous d1155c968e Kernel: dprintln file name is now relative
This makes file names much shorter

Bananymous aba82564f5 Kernel: Panic wont print stacktrace if it has already paniced
This prevents stack trace dump to panic and loop

Bananymous 370a958379 BuildSystem: GCC will now complain on functions with 1 KiB stack 2023-04-12 00:18:06 +03:00
Bananymous 8d6db168d6 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 2fabe1949c BAN: Move RefPtr to its own file and create New.h
New.h contains definitions for placement new operators and
BAN::allocator and BAN::dealloctor

Bananymous c660df14ec 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 9f977488fa BuildSystem: cmake can now build out libc
I can't seem to get libc++ build to work...

Bananymous 7752b02fb7 BuildSystem: remove now obsolete include directories from kernel build 2023-04-07 02:25:47 +03:00
Bananymous f70cd3ea77 BuildSystem: Cleanup cmake code
The buildsystem is kind of a mess. I will be writingn build
instructions soon.

Bananymous 5db5ff069a BuildSystem: you can now build the toolchain with cmake 2023-04-06 00:23:02 +03:00
Bananymous a1100624bf 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 002c2d0aca BuildSystem: remove non-existent file from kernel CMakeLists.txt 2023-04-03 19:02:25 +03:00
Bananymous 3998c5f955 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 762d22ed28 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 471ac80420 BuildSystem: building for 32-bit works now 2023-04-02 05:03:17 +03:00
Bananymous e49d3c7bfe 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

:)
