1======================= 2QEMU PCI serial devices 3======================= 4 5QEMU implements some PCI serial devices which are simple PCI 6wrappers around one or more 16550 UARTs. 7 8There is one single-port variant and two multiport-variants. Linux 9guests work out-of-the box with all cards. There is a Windows inf file 10(``docs/qemupciserial.inf``) to set up the cards in Windows guests. 11 12 13Single-port card 14---------------- 15 16Name: 17 ``pci-serial`` 18PCI ID: 19 1b36:0002 20PCI Region 0: 21 IO bar, 8 bytes long, with the 16550 UART mapped to it. 22Interrupt: 23 Wired to pin A. 24 25 26Multiport cards 27--------------- 28 29Name: 30 ``pci-serial-2x``, ``pci-serial-4x`` 31PCI ID: 32 1b36:0003 (``-2x``) and 1b36:0004 (``-4x``) 33PCI Region 0: 34 IO bar, with two or four 16550 UARTs mapped after each other. 35 The first is at offset 0, the second at offset 8, and so on. 36Interrupt: 37 Wired to pin A. 38
