C++ (Cpp) trace_reg_read Examples

Example #1

File: mmio.c Project: LastRitter/mt76

static u32 mt76_mmio_rr(struct mt76_dev *dev, u32 offset)
{
	u32 val;

	val = ioread32(dev->regs + offset);
	trace_reg_read(dev, offset, val);

	return val;
}

Example #2

File: usb.c Project: Kingbalou/mt7601u

u32 mt7601u_rr(struct mt7601u_dev *dev, u32 offset)
{
	int ret;
	__le32 reg;
	u32 val;

	WARN_ONCE(offset > USHRT_MAX, "read high off:%08x", offset);

	ret = mt7601u_vendor_request(dev, MT_VEND_MULTI_READ, USB_DIR_IN,
				     0, offset, &reg, sizeof(reg));
	val = le32_to_cpu(reg);
	if (ret > 0 && ret != sizeof(reg)) {
		dev_err(dev->dev, "Error: wrong size read:%d off:%08x\n",
			ret, offset);
		val = ~0;
	}

	trace_reg_read(dev, offset, val);
	return val;
