Andreas Kling	09b1b09c19	Kernel: Assert if rounding-up-to-page-size would wrap around to 0 ... If we try to align a number above 0xfffff000 to the next multiple of the page size (4 KiB), it would wrap around to 0. This is most likely never what we want, so let's assert if that happens.	2021-02-14 10:01:50 +01:00
Nico Weber	430b265cd4	AK: Rename KB, MB, GB to KiB, MiB, GiB ... The SI prefixes "k", "M", "G" mean "10^3", "10^6", "10^9". The IEC prefixes "Ki", "Mi", "Gi" mean "2^10", "2^20", "2^30". Let's use the correct name, at least in code. Only changes the name of the constants, no other behavior change.	2020-08-16 16:33:28 +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
