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

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

...
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
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

2023-01-09 21:57:03 +02:00
531f470132
Kernel: Add helper to map pages with base address and size
...
This allows us to easily map enough pages for buffer with known size
VESA driver can now allocate enough memory for whole framebuffer if it
doesn't fit in a single page (1920x1080 for example)
