Kernel: Use a multiboot header instead of a convoluted two-part bootloader. The old bootloader was hilariously complicated, requiring a floppy disk with the kernel on it, and a hard drive with the file system. This patch removes the floppy disk from the equation and replaces it with a multiboot header. This means the kernel can now be booted with qemu-system-i386 -kernel kernel 2019-04-01 22:43:07 +03:00			`ENTRY(start)`
Import the "gerbert" kernel I worked on earlier this year. It's a lot crappier than I remembered it. It's gonna need a lot of work. 2018-10-16 12:01:38 +03:00

Revert "Kernel: Move Kernel mapping to 0xc0000000" This reverts commit bd33c6627394b2166e1419965dd3b2d2dc0c401f. This broke the network card drivers, since they depended on kmalloc addresses being identity-mapped. 2019-11-23 19:27:09 +03:00			`. = 0x100000;`

Kernel: Removing hardcoded offsets from Memory Manager Now the kernel page directory and the page tables are located at a safe address, to prevent from paging data colliding with garbage. 2019-11-08 17:37:33 +03:00			`*(.page_tables)`

Kernel: Add bare minimum for global constructors (#707) Add text.startup to the .text block, add .ctors as well. Use them in init.cpp to call global constructors after gtd and idt init. That way any funky constructors should be ok. Also defines some Itanium C++ ABI methods that probably shouldn't be, but without them the linker gets very angry. If the code ever actually tries to use __dso_handle or call __cxa_atexit, there's bigger problems with the kernel. Bit of a hack would be an understatement but hey. It works :) 2019-10-31 21:01:13 +03:00			`*(.text.startup)`
