Andreas Kling	9a157b5e81	Revert "Kernel: Move Kernel mapping to 0xc0000000" ... This reverts commit bd33c66273. This broke the network card drivers, since they depended on kmalloc addresses being identity-mapped.	2019-11-23 17:27:09 +01:00
Jesse Buhagiar	bd33c66273	Kernel: Move Kernel mapping to 0xc0000000 ... The kernel is now no longer identity mapped to the bottom 8MiB of memory, and is now mapped at the higher address of `0xc0000000`. The lower ~1MiB of memory (from GRUB's mmap), however is still identity mapped to provide an easy way for the kernel to get physical pages for things such as DMA etc. These could later be mapped to the higher address too, as I'm not too sure how to go about doing this elegantly without a lot of address subtractions.	2019-11-22 16:23:23 +01:00
Andreas Kling	19398cd7d5	Kernel: Reorganize memory layout a bit ... Move the kernel image to the 1 MB physical mark. This prevents it from colliding with stuff like the VGA memory. This was causing us to end up with the BIOS screen contents sneaking into kernel memory sometimes. This patch also bumps the kmalloc heap size from 1 MB to 3 MB. It's not the perfect permanent solution (obviously) but it should get the OOM monkey off our backs for a while.	2019-11-04 12:04:35 +01:00
