C++ (Cpp) __after_dc_op Examples

Example #1

File: cache.c Project: DIGImend/linux

/*
 * D-Cache Line ops: Per Line INV (discard or wback+discard) or FLUSH (wback)
 */
static inline void __dc_line_op(unsigned long paddr, unsigned long vaddr,
				unsigned long sz, const int op)
{
	unsigned long flags;

	local_irq_save(flags);

	__before_dc_op(op);

	__cache_line_loop(paddr, vaddr, sz, op);

	__after_dc_op(op);

	local_irq_restore(flags);
}

Example #2

File: cache.c Project: DIGImend/linux

/*
 * Operation on Entire D-Cache
 * @op = {OP_INV, OP_FLUSH, OP_FLUSH_N_INV}
 * Note that constant propagation ensures all the checks are gone
 * in generated code
 */

	else
		aux = ARC_REG_DC_FLSH;

	write_aux_reg(aux, 0x1);

	__after_dc_op(op);
}
