Member Function Documentation

enable_cpu_features()

void iris::arch::ArchProcessor::enable_cpu_features

(

bool

print_info = true

)

Enable CPU features for the current processor.

Note

This must be called once at boot for each logical processor.

fallback_kernel_stack()

auto iris::arch::ArchProcessor::fallback_kernel_stack ( ) const -> uptr

inline

gdt()

auto iris::arch::ArchProcessor::gdt ( ) -> auto&

inline

local_apic()

auto iris::arch::ArchProcessor::local_apic ( ) -> x86::amd64::LocalApic&

inline

Get the local APIC.

Warning

This function is only safe to call if global_state().arch_readonly_state.use_apic is true, and the local APIC has been initialized.

local_apic_callback()

void iris::arch::ArchProcessor::local_apic_callback ( IrqContext & context )

inline

set_fallback_kernel_stack()

void iris::arch::ArchProcessor::set_fallback_kernel_stack ( uptr stack )

inline

set_local_apic()

void iris::arch::ArchProcessor::set_local_apic ( x86::amd64::LocalApic local_apic )

inline

set_local_apic_callback()

void iris::arch::ArchProcessor::set_local_apic_callback ( di::Function< void(IrqContext &)> callback )

inline

setup_fpu_support_for_processor()

void iris::arch::ArchProcessor::setup_fpu_support_for_processor

(

bool

print_info = true

)

Setup the processor to allow floating-point / SIMD operations.

Note

This must be called once at boot for each logical processor.

tss()

auto iris::arch::ArchProcessor::tss ( ) -> auto&

inline
