Bananymous 979a5960e4 Kernel: We don't use floating point arithemtic anymore in kernel 2023-01-10 11:10:17 +02:00
Bananymous efd8638a96 Kernel: Improve kernel panic message and rename it 'panic'->'Panic' 2023-01-09 21:57:03 +02:00
Bananymous 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)

Bananymous fd4fdffd46 BAN::Formatter now takes putc like function as a parameter 
This allows us to use capturing lambdas as a putc like function
 2022-12-27 19:55:07 +02:00
Bananymous 98fc72b0d0 Kernel: kmalloc now aligns everything by alignof(max_align_t) 
kmalloc properly aligns everything now.

I also changed so that kmalloc addresses are stored as uintptr_t
instead of void* or uint8_t* for easier arithemetic and less casting
