* xen:pvhvm: Modpost section mismatch fixRaghavendra D Prabhu2011-07-111-1/+1
| | | | | | | | | | | Removing __init from check_platform_magic since it is called by xen_unplug_emulated_devices in non-init contexts (It probably gets inlined because of -finline-functions-called-once, removing __init is more to avoid mismatch being reported).

* xen: unplug the emulated devices at resume timeStefano Stabellini2010-12-021-1/+1
| | | | | | Early after being resumed we need to unplug again the emulated devices. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
* xen: pvhvm: rename xen_emul_unplug=ignore to =unnnecessaryIan Campbell2010-08-231-6/+7
| | | | | | | | | | | | | | | It is not immediately clear what this option causes to become ignored. The actual meaning is that it is not necessary to unplug the emulated devices to safely use the PV ones, even if the platform does not support the unplug protocol. (pressumably the user will only add this option if they have ensured that their domain configuration is safe). I think xen_emul_unplug=unnecessary better captures this.

* xen: pvhvm: allow user to request no emulated device unplugIan Campbell2010-08-231-0/+5
| | | | | | | | | | this allows the user to disable pvhvm and revert to emulated devices in case of a system misconfiguration (e.g. initramfs with only emulated drivers in it).

* Introduce CONFIG_XEN_PVHVM compile optionStefano Stabellini2010-07-291-0/+2
| | | | | | | This patch introduce a CONFIG_XEN_PVHVM compile time option to enable/disable Xen PV on HVM support. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
* x86: Unplug emulated disks and nics.Stefano Stabellini2010-07-261-0/+135
Add a xen_emul_unplug command line option to the kernel to unplug xen emulated disks and nics. Set the default value of xen_emul_unplug depending on whether or not the Xen PV frontends and the Xen platform PCI driver have been compiled for this kernel (modules or built-in are both OK). The user can specify xen_emul_unplug=ignore to enable PV drivers on HVM even if the host platform doesn't support unplug.
