Bananymous f10a57dcec BAN: Add RefCounted<> and Unique<> 
We have now maybe functional smart pointers
 2023-01-31 18:43:09 +02:00
Bananymous 1687028ed5 Kernel: Add constructor and destructor to MMU 2023-01-30 18:54:04 +02:00
Bananymous 3d5f1b5a86 Kernel: Change default host to x86_64 2023-01-30 18:53:30 +02:00
Bananymous 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
Bananymous bfe3426f6d Kernel: Add processor dump flag to APIC 2023-01-26 13:13:46 +02:00
Bananymous 6418d7cfc3 Kernel: Add Other GDT entries to x86_64 2023-01-26 12:53:04 +02:00
Bananymous 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
Bananymous e00d18029d Kernel: rewrite some of APIC since it didn't work with xsdts for some reason 2023-01-26 02:57:14 +02:00
Bananymous 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 :)
 2023-01-26 02:57:14 +02:00
Bananymous 589f338357 Kernel: Cleanup IDT register dump inline assembly 2023-01-26 02:57:14 +02:00
Bananymous 05b48fa71c Kernel: add gcc option to make sure we have (r/e)bp saved on stack 2023-01-26 02:57:14 +02:00
Bananymous aa0757e135 Kernel: Move dump_stacktrace from panic -> debug 2023-01-26 02:57:14 +02:00
Bananymous 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?
 2023-01-26 02:55:37 +02:00
Bananymous 9c31790359 Kernel: Add option to disable Serial output 
This makes all debug output to appear on the TTY
 2023-01-25 22:51:42 +02:00
Bananymous 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
 2023-01-25 22:51:42 +02:00
Bananymous b315fdc27f Kernel: Finally managed to get 64-bit working 
I had weird problems with interrupts but everything should work now
 2023-01-25 19:19:28 +02:00
Bananymous c4670f49d4 Kernel: Refactor some IDT code 2023-01-25 19:19:28 +02:00

Bananymous ba53582f23 Kernel: Rewrite APIC and PIC more OOP friendly 
x86_64 port is slowly coming together
 2023-01-23 20:13:57 +02:00
Bananymous b50bb03ed4 Kernel: Panic now halts machine even if we get spurious irqs 2023-01-23 18:25:48 +02:00
Bananymous 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
Bananymous 7c6d474a3a BAN: Add basic ScopeGuard 2023-01-23 17:41:34 +02:00
Bananymous 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
 2023-01-23 13:21:53 +02:00

Bananymous 026fdc251c Kernel: Add kmalloc_eternal back 2023-01-22 03:10:48 +02:00
Bananymous 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
Bananymous 6ec4ba3dc9 Kernel: Move dump_backtrace() out of arch. 
I discovered __builtin_frame_address()

Bananymous bb051604a1 Kernel: Move dump_stacktrace() to arch folder 
It uses mov instruction which has different register on x86/x86-64
 2023-01-21 22:16:31 +02:00
