118 * - Bootloader/pre-kernel environments that need to parse ACPI tables, but
119 * don't actually need a fully-featured AML interpreter, and everything else
120 * that a full APCI implementation entails.
121 * - A micro-kernel that has the full AML interpreter running in userspace, but
122 * still needs to parse ACPI tables to bootstrap allocators, timers, SMP etc.
123 * - A WIP kernel that needs to parse ACPI tables for bootrapping SMP/timers,
124 * ECAM, etc., but doesn't yet have enough subsystems implemented in order
125 * to run a fully-featured AML interpreter.
