C++ (Cpp) fstate_save Examples

Example #1

File: signal.c Project: congwang/linux

static long save_fp_state(struct pt_regs *regs,
			  union __riscv_fp_state *sc_fpregs)
{
	long err;
	struct __riscv_d_ext_state __user *state = &sc_fpregs->d;
	size_t i;

	fstate_save(current, regs);
	err = __copy_to_user(state, &current->thread.fstate, sizeof(*state));
	if (unlikely(err))
		return err;

	/* We support no other extension state at this time. */
	for (i = 0; i < ARRAY_SIZE(sc_fpregs->q.reserved); i++) {
		err = __put_user(0, &sc_fpregs->q.reserved[i]);
		if (unlikely(err))
			break;
	}

	return err;
}

Example #2

File: process.c Project: asb/riscv-linux

{
	fstate_save(src, task_pt_regs(src));
	*dst = *src;
	return 0;
