Required Methods

fn read_registers(vcpu: &T) -> Result<<GdbArch as Arch>::Registers, Self::Error>

Reads vCPU’s registers.

fn write_registers( vcpu: &T, regs: &<GdbArch as Arch>::Registers, ) -> Result<(), Self::Error>

Writes vCPU’s registers.

fn read_memory( vcpu: &T, guest_mem: &GuestMemory, vaddr: GuestAddress, len: usize, ) -> Result<Vec<u8>, Self::Error>

Reads bytes from the guest memory.

fn write_memory( vcpu: &T, guest_mem: &GuestMemory, vaddr: GuestAddress, buf: &[u8], ) -> Result<(), Self::Error>

Writes bytes to the specified guest memory.

fn read_register( vcpu: &T, reg_id: <GdbArch as Arch>::RegId, ) -> Result<Vec<u8>, Self::Error>

Reads bytes from the guest register.

Returns an empty vector if reg_id is valid but the register is not available.

fn write_register( vcpu: &T, reg_id: <GdbArch as Arch>::RegId, data: &[u8], ) -> Result<(), Self::Error>

Writes bytes to the specified guest register.

fn enable_singlestep(vcpu: &T) -> Result<(), Self::Error>

Make the next vCPU’s run single-step.

fn get_max_hw_breakpoints(vcpu: &T) -> Result<usize, Self::Error>

Get maximum number of hardware breakpoints.

fn set_hw_breakpoints( vcpu: &T, breakpoints: &[GuestAddress], ) -> Result<(), Self::Error>

Set hardware breakpoints at the given addresses.
