Module boot 

CPU initialization for the selected target.

Re-exports

pub use super::gdt::TrapStorageProvider;

Modules

trap_storage_provider

Statically bound calls and implementation binding for TrapStorageProvider.

Structs

BootVectorTable

Owned early exception descriptors for the current code mapping and selector. Keep the value at a stable address while any CPU has it installed.

DescriptorAddress

A canonical 64-bit virtual memory address.

GdtEntry

8-byte entry in a descriptor table.

GlobalDescriptorTable

A 64-bit mode global descriptor table (GDT).

SegmentSelector

Specifies which element to load into a segment from descriptor tables (i.e., is a index to LDT or GDT table with some additional flags).

TaskStateSegment

In 64-bit mode the TSS holds information that is not directly related to the task-switch mechanism, but is used for stack switching when an interrupt or exception occurs.

TrapStorage

Runtime-owned memory retained by this CPU’s descriptor registers.

VirtAddrNotValid

A passed u64 was not a valid virtual address.

Enums

Descriptor

A 64-bit mode segment descriptor.

InvalidIoMap

The given IO permissions bitmap is invalid.

PrivilegeLevel

Represents a protection ring level.

Constants

KERNEL_CR0_STATE

Control-register state installed before a CPU enters the kernel runtime.

Traits

TrapStorageProvider

Supplies descriptor storage once for each initialized CPU.

Functions

assert_kernel_cr0_state^⚠

Checks the complete early kernel CR0 contract on this CPU.

configure_paging^⚠

Installs the kernel CR0 state and enables global page translations.

current_vector_table

Returns the currently installed IDT base.

enable_execute_disable^⚠

Enables architectural execute-disable page permissions.

enable_xsave_features^⚠

Enables supported x87, SSE and AVX components in the boot XCR0 policy.

init_trap

Initializes trap handling on the current CPU.

install_boot_vectors^⚠

Installs the immutable early IDT on the current CPU.

jump_to^⚠

Transfers to a Rust/C entry on a new stack with a terminating return slot.
