Hi, This patch series tackles serial device hotplug. The first four patches have been on the list before, they implement pci-serial devices featuring a hot-pluggable 16550 uart and got some minor tweaks only. The next two patches update the usb-serial device. It will only show up in the guest when the chardev is open. You'll see the difference with socket chardevs: If you open the chardev (by connecting to the socket) the device will show up in the guest, on close (disconnect) it will disappear. Final patch adds chardev hotplug to the mix, which makes the other patches alot more useful. It is the missing bit needed to really hotplug serial devices: (qemu) chardev_add pciserial file /root/hotchardev.log (qemu) device_add pci-serial,chardev=pciserial,id=pciserial And the reverse: (qemu) device_del pciserial (qemu) chardev_del pciserial please review & pull, Gerd The following changes since commit b4ae3cfa57b8c1bdbbd7b7d420971e9171203ade: ssi: Add slave autoconnect helper (2012-10-10 11:13:32 +1000) are available in the git repository at: git://git.kraxel.org/qemu serial.1 Gerd Hoffmann (7): serial: split serial.c serial: add pci variant serial: add windows inf file for the pci card to docs serial: add 2x + 4x pci variant usb-serial: don't magically zap chardev on umplug usb-serial: only expose device in guest when the chardev is open chardev: add hotplug support. default-configs/pci.mak | 2 + docs/qemupciserial.inf | 109 ++++++++++++++++++ hmp-commands.hx | 49 ++++++++ hmp.c | 39 +++++++ hmp.h | 2 + hw/Makefile.objs | 3 +- hw/alpha_dp264.c | 1 + hw/kzm.c | 2 +- hw/mips_fulong2e.c | 1 + hw/mips_jazz.c | 1 + hw/mips_malta.c | 1 + hw/mips_mipssim.c | 2 +- hw/mips_r4k.c | 1 + hw/musicpal.c | 2 +- hw/omap_uart.c | 3 +- hw/openrisc_sim.c | 3 +- hw/pc.c | 1 + hw/pc.h | 27 ----- hw/pci_ids.h | 1 + hw/petalogix_ml605_mmu.c | 2 +- hw/ppc/e500.c | 2 +- hw/ppc405_uc.c | 2 +- hw/ppc440_bamboo.c | 2 +- hw/ppc_prep.c | 1 + hw/pxa2xx.c | 2 +- hw/serial-isa.c | 130 ++++++++++++++++++++++ hw/serial-pci.c | 272 ++++++++++++++++++++++++++++++++++++++++++++++ hw/serial.c | 149 ++----------------------- hw/serial.h | 74 +++++++++++++ hw/sm501.c | 2 +- hw/sun4u.c | 1 + hw/usb/dev-serial.c | 21 +++- hw/virtex_ml507.c | 2 +- hw/xtensa_lx60.c | 3 +- qapi-schema.json | 46 ++++++++ qemu-char.c | 74 +++++++++++++ qmp-commands.hx | 61 ++++++++++ 37 files changed, 913 insertions(+), 183 deletions(-) create mode 100644 docs/qemupciserial.inf create mode 100644 hw/serial-isa.c create mode 100644 hw/serial-pci.c create mode 100644 hw/serial.h
