6 * General FPU state handling cleanups
27 * High level FPU state handling functions:
83 extern void fpstate_init(union fpregs_state *state);
203 asm volatile( "fxsave %[fx]" : [fx] "=m" (fpu->state.fxsave));
205 asm volatile("fxsaveq %[fx]" : [fx] "=m" (fpu->state.fxsave));
304 * state we set at boot time should be valid.
423 * pending. Clear the x87 state here by setting it to fixed values.
446 * The in-register FPU state for an FPU context on a CPU is assumed to be
450 * If the FPU register state is valid, the kernel can skip restoring the
451 * FPU state from memory.
454 * FPU state for a task MUST let the rest of the kernel know that the
505 copy_kernel_to_fpregs(&fpu->state);
513 * FPU state switching for scheduling.
517 * - switch_fpu_prepare() saves the old state.
520 * - switch_fpu_finish() sets TIF_NEED_FPU_LOAD; the floating point state
524 * are saved in the current thread's FPU register state.
555 * complete FPU state until the return to userland.
572 * PKRU state is switched eagerly because it needs to be valid before we
578 * then the PKRU component was in init state, which means
584 pk = get_xsave_addr(&next_fpu->state.xsave, XFEATURE_PKRU);
