Struct BootArchitectureFlags

pub struct BootArchitectureFlags(/* private fields */);

Flags which can be used by the OS to guide the assumptions it can make in initializing hardware on IA-PC platforms.

Implementations

impl BootArchitectureFlags

pub const fn new() -> Self

Creates a new default initialized bitfield.

impl BootArchitectureFlags

pub fn legacy_devices(&self) -> bool

Whether the motherboard supports user-visible devices on the LPC or ISA bus. User-visible devices are devices that have end-user accessible connectors (for example, LPT port), or devices for which the OS must load a device driver so that an end-user application can use a device. If false, the OS may assume there are no such devices and that all devices in the system can be detected exclusively via industry standard device enumeration mechanisms (including the ACPI namespace).

pub fn has_8042_controller(&self) -> bool

Whether the motherboard contains support for a port 60 and 64 based keyboard controller, usually implemented as an 8042 or equivalent micro-controller.

pub fn vga_not_present(&self) -> bool

Whether OSPM must not blindly probe the VGA hardware (that responds to MMIO addresses A0000h-BFFFFh and IO ports 3B0h-3BBh and 3C0h-3DFh) that may cause machine check on this system. If false, it is safe to probe the VGA hardware.

pub fn msi_not_supported(&self) -> bool

Whether OSPM must not enable Message Signalled Interrupts (MSI) on this platform.

pub fn pcie_aspm_controls(&self) -> bool

Whether OSPM must not enable OSPM ASPM control on this platform.

pub fn cmos_rtc_not_present(&self) -> bool

Whether the CMOS RTC is either not implemented, or does not exist at the legacy addresses. OSPM uses the Control Method Time and Alarm Namespace device instead.
