Philippe Mathieu-Daudé 543671d990 hw/char/sh_serial: Return correct number of empty RX FIFO elements ... In the IOCanReadHandler sh_serial_can_receive(), if the Serial Control Register 'Receive Enable' bit is set (bit 4), then we return a size of (1 << 4) which happens to be equal to 16, so effectively SH_RX_FIFO_LENGTH. The IOReadHandler, sh_serial_receive1() takes care to receive multiple chars, but if the FIFO is partly filled, we only process the number of free slots in the FIFO, discarding the other chars! Fix by returning how many elements the FIFO can queue in the IOCanReadHandler, so we don't have to process more than that in the IOReadHandler, thus not discarding anything. Remove the now unnecessary check on 's->rx_cnt < SH_RX_FIFO_LENGTH' in IOReadHandler, reducing the block indentation.
