Struct UserContext Copy item path

impl UserContext

pub fn general_regs(&self) -> &RawGeneralRegs

Returns a reference to the general registers.

pub fn general_regs_mut(&mut self) -> &mut RawGeneralRegs

Returns a mutable reference to the general registers

pub fn trap_information(&self) -> &CpuExceptionInfo

Returns the trap information.

pub fn fpu_state(&self) -> &FpuState

Returns a reference to the FPU state.

pub fn fpu_state_mut(&mut self) -> &mut FpuState

Returns a mutable reference to the FPU state.

pub fn set_tls_pointer(&mut self, tls: usize)

Sets thread-local storage pointer.

pub fn tls_pointer(&self) -> usize

Gets thread-local storage pointer.

pub fn activate_tls_pointer(&self)

Activates thread-local storage pointer on the current CPU.

§Safety

The method by itself is safe because the value of the TLS register won’t affect kernel code. But if the user relies on the TLS pointer, make sure that the pointer is correctly set when entering the user space.
