1bd8b0fe5c Kernel: Sleep now actually sleeps and allows idling 2023-02-19 18:52:25 +02:00
6fab26692b Kernel: remove unnecessary function from x86_64 Thread.S 2023-02-02 23:48:18 +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.

c85b97abee Kernel: fix some of i368 IDT. This was really broken 2023-02-02 15:52:06 +02:00
01f267a321 Kernel: fix spinlock for i386 2023-02-02 15:49:00 +02:00
9b8de5025a 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 :)

337569b0ca Kernel: Implement basic SpinLock 2023-02-01 01:52:52 +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
2023-01-31 18:43:09 +02:00
1687028ed5 Kernel: Add constructor and destructor to MMU 2023-01-30 18:54:04 +02:00
6dc22b7251 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
6418d7cfc3 Kernel: Add Other GDT entries to x86_64 2023-01-26 12:53:04 +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 :)

589f338357 Kernel: Cleanup IDT register dump inline assembly 2023-01-26 02:57:14 +02:00
e87026f01d 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?

c0bc002ac6 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

b315fdc27f Kernel: Finally managed to get 64-bit working
I had weird problems with interrupts but everything should work now

c4670f49d4 Kernel: Refactor some IDT code 2023-01-25 19:19:28 +02:00
ba53582f23 Kernel: Rewrite APIC and PIC more OOP friendly
x86_64 port is slowly coming together
2023-01-23 20:13:57 +02:00
54043288cb 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.
2023-01-23 18:12:52 +02:00
1b9f7aa815 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

10c7ef7baa Kernel: MMU rename weird variable 2023-01-22 20:16:44 +02:00
62469c529f Kernel: IDT now allocates descriptors with kmalloc_eternal 2023-01-22 03:18:42 +02:00
cdd27ae3db Kernel: rename MMU::m_page_directory_pointer_table -> m_highest_paging_stuct
This might not always be pdpt. In x86_64 it is pml4/pml5
2023-01-22 03:03:58 +02:00
6ec4ba3dc9 Kernel: Move dump_backtrace() out of arch.
I discovered __builtin_frame_address()

bb051604a1 Kernel: Move dump_stacktrace() to arch folder
It uses mov instruction which has different register on x86/x86-64
