state

State state[Core::MAX]

static

Storage for the current core register state.

Updated at the beginning of interrupt handling and written back at the end (with possibly modified values)

fpu_state

FPU::State fpu_state[Core::MAX]

static

Storage for the current FPU state of the core.

Stored when State::save is called using FXSAVE (in FPU::State::save()) and later restored with FXRSTOR (in FPU::State::restore()) – with modified values if necessary
