c604c074a1 Kernel: Rename ASSERT() to ensure()
Doesn't get stripped on release builds, so it shouldn't be named assert.

22740e69bf Kernel: Add support for the NX bit
Not support, actually. We now REQUIRE it.

712f4f5e51 KernelHeap: Add more debug logging 2022-10-20 18:49:33 +02:00
b035795eb3 Kernel: Move errno.h and (k)assert.h out of the main include directory
This is mostly so IDEs don't pick them up instead of the userspace headers :)

62d631f1b4 Kernel: Rename assert.h to kassert.h so IDEs pickup the kernel header instead of the userspace one 2022-10-15 12:56:48 +02:00
ee712432bd Some more multiple address space stuff
This page-faults. This is because the memory where the ELF should be is all zeroes, which the CPU tries to interpret.

83e6b8cd21 VMM: Fix naming convention 2022-10-13 18:42:53 +02:00
69a9f7f06a Kernel: Move VMM from a class to a namespace
Also, rename the ugly Paging::VirtualMemoryManager name to just 'VMM'. Which is now used instead of kernelVMM.

eaea4603c6 MemoryManager: Fix logging when built with debug logging
That is to say, -DMM_DEBUG

d5f59b666a Kernel/Memory: Use %p in printf 2022-10-08 18:21:02 +02:00
abcf1b6118 Define PAGE_SIZE as 4096 and use it everywhere instead of using 4096 as a magic number 2022-10-08 14:52:28 +02:00
8f310dd307 PMM: Map the page bitmap to kernel heap once the PMM and VMM are both initialized 2022-10-04 18:36:09 +02:00
e769cb45a7 MemoryManager: add get_page_at and get_pages_at functions to map any physical memory at a fixed virtual address (inverse of get_mapping and get_mappings) 2022-10-01 12:12:50 +02:00
a078a11dde Move PMM and VMM initialization into MemoryManager::init 2022-09-25 17:38:17 +02:00
704a23d0ad Sanity checks 2022-09-24 23:09:39 +02:00
2511b7d7a1 Add optional (compile-opt-in) debug logging to the MemoryManager (which helped catch the bug that got fixed in the previous commit) 2022-09-24 22:38:07 +02:00
3891d0c52e Rename KernelMemoryManager to MemoryManager
Kind of a more catchy name, isn't it?
