Struct rstubs::arch::acpi::Acpi

pub struct Acpi {
    root: &'static SysDescTable,
    entry_size: usize,
}

ACPI is the successor to APM (Advanced Power Management), aiming to give the operating system more control over the hardware.

This extended control, for instance, enables the operating system to assign a particular amount of energy to every device (e.g., by disabling a device or changing to standby mode). For this purpose, BIOS and chipset provide a set of tables that describe the system and its components and provide routines the OS can call. These tables contain details about the system, such as the number of CPU cores and the LAPIC/IOAPIC, which are determined during system boot.

Fields

root: &'static SysDescTable

entry_size: usize

Implementations

impl Acpi

pub fn load() -> Result<Self, ApicError>

pub const fn len(&self) -> usize

pub fn entry(&self, i: usize) -> Option<&'static SysDescTable>

Get the i-th entry

pub fn find(&self, signature: [u8; 4]) -> Option<&'static SysDescTable>

Find the given system descriptor table
