Kernel: Shell is now launched as a capturing lambda
2023-02-02 23:27:51 +02:00

Kernel: Update shell thread command to run following command as thread
...
'thread echo "Hello World"' runs the command 'echo "Hello World"' after
5 seconds have passed. This was just my test code for threading
2023-02-02 23:26:19 +02:00
5b5e620d8a
Kernel: Improve multithreading support
...
We can now use arbitary BAN::function<void(...)> as the Thread.
I also implemented multithreading for i386 since it was not done
on the initial multithreading commit.

BAN: Add getter for Function size

Kernel: fix some of i368 IDT. This was really broken
2023-02-02 15:52:06 +02:00
117d1de038
Kernel: panic does not need to include <kernel/kprint.h>
...
This allows us to not have kprint available literally everywhere
2023-02-02 15:51:15 +02:00

Kernel: Add some more cxxabi functionality
...
We can now declate static variables in functions
2023-02-02 15:50:26 +02:00

Kernel: Add is_locked() to spinlock

I think this is atomic read

All: rename every function from UpperCamelCase to snake_case
...
This was a mess since I didn't know which to use but now I decided
to go with snake_case :)

BAN: Rewrite Traits and add some more of them
2023-02-01 20:05:34 +02:00
6a9d60a8fb
Kernel: Implement somewhat functioning multithread support
...
This still uses only a single cpu, but we can now have 'parallelization'
This seems to work fine in qemu and bochs, but my own computer did not
like this when I last tried.
I have absolutely no idea how multithreading should actually be
implmemented and I just thought and implemented the most simple one I
could think of. This might not be in any way correct :D

2023-02-01 01:22:19 +02:00
56d6b2af3d
BAN: TRY() now returns the error itself and not ErrorOr<>
...
This allows us to use TRY with different ErrorOr<> templates
2023-02-01 01:21:14 +02:00

BAN: Add needed include to Function
2023-01-31 18:43:24 +02:00

2023-01-31 18:43:09 +02:00
cb3b62d665
Kernel: Only allocate single GDT entry during boot.S
...
When we need more, we should probably initialize rest of them
in cpp code

Kernel: Add no sse and sse2 for kernel code

BAN: Add RefCounted<> and Unique<>
...
We have now maybe functional smart pointers

Kernel: Add actual register values to x86_64 kernel panic
...
Very hackish implementation, but we now get actual registers at the
time of the interrupt happening
2023-01-30 18:52:38 +02:00

f0093ed2fd
Kernel: kmalloc_eternal now updates the used/free values
...
I also improved the kmalloc_dump_info() formatting. We format the
values as 8-digit hex numbers since (atleast for now) the kmalloc
will always be under 4 GiB address and size :)
2023-01-26 03:04:19 +02:00

2023-01-26 02:57:14 +02:00
35d2e27292
Kernel: Improve MMU
...
We don't have to invalidate page in AllocatePage() if we don't make
any changes. We also should not assert on deallocating non-present
pages, just return early :)

Kernel: I have no idea what this commit does
...
I had committed a change in IDT but reverted it now.
This propably only adds a spurious interrupt detection to common cpp
interrupt handler?
2023-01-26 02:55:37 +02:00
9c31790359
Kernel: Add option to disable Serial output

This makes all debug output to appear on the TTY

Kernel: Move debug printing to its own file
...
It didn't make sense that dprint was defined in Serial.h.
We also now dump dprint to tty if there is no serial and tty is initialized
2023-01-25 22:51:42 +02:00

Kernel: Move CPUID out of arch/
...
CPUID instructions behaves the same on x86 and x86_64. I am not
planning on supporting any non x86 based architectures.

Kernel: Rewrite the whole VESA driver
...
We dont support vga text mode currently. I might add it later if needed.
I also removed mouse 'support' from Shell since it didn't do anything
and I didn't implement arbitary bitmap rendering to framebuffer
