Bananymous c791a1c200 Bootloader: Build with cmake instead of custom script 2023-11-14 03:44:47 +02:00
Bananymous bd3f2bb61c Bootloader: Split bootloader into multiple files 
This cleans up the code since bootloader is starting to near 1k lines

Bananymous 7ca9a961b3 Bootloader move bootloader code from arch directory 
The os itself only supports x86 so this won't matter. x86_64 and i386
use the same bootloader assembly.

Bananymous 381cfdad77 Bootloader: Continue work on bootloader 
Bootloader can now get the memory map and read cmdline from user.

Now 'just' video mode query, ext2 and ELF parsing are needed :D

Bananymous f6c312a6b3 BuildSystem: using sysroot doesn't need root privileges anymore! 
Sysroot is now created with fakeroot. This allows root access to be
only needed for disk image creation, since it uses loopback devices.

Bananymous ca34ece8ef BAN: Update ASSERT api 
its now much harder to mix < with <= and > with >=

Bananymous 640d27748f Kernel: Temporarily force FileBackedRegion mappings writable 
Now that write-protect bit is enabled this is neccessary.
 2023-10-30 19:08:33 +02:00
Bananymous 42772611ce Kernel: Add fast page to page table 
Add "fast page" to KERNEL_OFFSET. This is always present in page
tables and only requires changing the page table entry to map. This
requires no interrupts since it should only be for very operations
like memcpy.

I used to map all temporary mappings to vaddr 0, but this is much
better. C++ standard always says that nullptr access is undefined
and this gets rid of it.

Fixed some bugs I found along the way
