* xenstored: Fix processing of zero-length messagesDaniel De Graaf2011-11-011-1/+0
| | | | | | | | | | | When a message with zero length is sent to xenstore, the body of the message was not processed until the socket or ring had more data to read; this will cause deadlocks if the requestor is waiting on a response to continue.

* libxl: remove libxl_device_console_add.Ian Campbell2011-10-184-33/+0
| | | | | | | | | | | | It has no callers, the only code which adds consoles in internal to libxl and uses libxl__device_console_add directly. Rather than worrying about what the public API should look like in this case simply remove it, adding new APIs is much easier than fixing broken ones...

* libxl: split forced and non-forced uses of libxl__device_delIan Campbell2011-10-184-25/+40
| | | | | | | | | | | | | | | | | Most forced users can now simply call libxl__device_destroy directly. libxl__devices_destroy is something of a special case, it is really just iterating over an opaque set of xenstore directories and removing them. Until this can be refactored just do the force-remove case manually, doing otherwise led to too much entanglement with the other callers of libxl__device_destroy which do know about specific device types. For the time being do the same in libxl__device_pci_remove_xenstore.

* libxl: separate forced and non-forced device remove.Ian Campbell2011-10-183-13/+25
| | | | | | | | | | | | | | | | | | | | | | | The function libxl__device_destroy currently takes a force parameter however: * in the forced case we initiate a graceful shutdown and then immediately nuke the backend directory, quite likely before anyone got a chance to react. * the callers all have a "wait" variable and pass in "!wait" as the force argument which is confusing since not waiting is not really the same thing as forcing the destroy. Therefore split the function into libxl__device_remove and libxl__device_destroy. The former initiates a graceful shutdown which the latter simply nukes the backend directory. This makes some of the callers look a bit odd but that should fall out as I continue to pull this piece of string.

* hvmloader/acpi/dsdt: Fix PCI hotplug with the new qemu-xen.Anthony PERARD2011-10-282-60/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ACPI PIIX4 device in QEMU upstream as not the same behavior to handle PCI hotplug. This patch introduce the necessary change to the DSDT ACPI table to behave as expceted by the new QEMU. To switch to this new DSDT table version, there is a new option --dm-version to mk_dsdt. Change are inspired by SeaBIOS DSDT source code. There is few things missing with the new QEMU: - QEMU provide the plugged/unplugged status only per slot (and not per func like qemu-xen-traditionnal. - I did not include the _STA ACPI method that give the status of a device (present, functionning properly) because qemu-xen does not handle it. - I did not include the _RMV method that say if the device can be removed, because the IO port of QEMU that give this status always return true. In SeaBIOS table, they have a specific _RMV method for VGA, ISA that return false. But I'm not sure that we can do the same in Xen. So, the only way to remove a device is from outside of the guest (like with xl pci-detatch), and can not be initiated from inside.
