Ben Wiederhake	0d79e57c4d	Kernel: Fix various forward declarations ... I decided to modify MappedROM.h because all other entried in Forward.h are also classes, and this is visually more pleasing. Other than that, it just doesn't make any difference which way we resolve the conflicts.	2020-09-12 13:46:15 +02:00
Andreas Kling	4b847810bf	Kernel: Simplify scanning BIOS/EBDA and MP parser initialization ... Add a MappedROM::find_chunk_starting_with() helper since that's a very common usage pattern in clients of this code. Also convert MultiProcessorParser from a persistent singleton object to a temporary object constructed via a failable factory function.	2020-05-22 13:36:57 +02:00
Andreas Kling	84b7bc5e14	Kernel: Add convenient ways to map whole BIOS and EBDA into memory ... This patch adds a MappedROM abstraction to the Kernel VM subsystem. It's basically the read-only byte buffer equivalent of a TypedMapping. We use this in the ACPI and MP table parsers to scan for interesting stuff in low memory instead of doing a bunch of address arithmetic.	2020-05-22 13:17:38 +02:00
