First megabyte protection #19

Closed vodozhaba closed 6 years ago

vodozhaba commented 6 years ago

The physical memory manager never allocates the NULL frame, however, it may allocate other frames in the first megabyte, e.g. the framebuffer, which will lead to data corruption and/or unexpected peripheral device behaviour.

Apparently, the first 16MiB are protected. Closed.
