* accel: Pass MachineState object to accel init functionsEduardo Habkost2014-10-091-1/+1
| | | | | | | | | | | Most of the machine options and machine state information is in the MachineState object, not on the MachineClass. This will allow init functions to use the MachineState object directly instead of qemu_get_machine_opts() or the current_machine global.

* accel: Rename 'init' method to 'init_machine'Eduardo Habkost2014-10-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Today, all accelerator init functions affect some global state: * tcg_init() calls tcg_exec_init() and affects globals such as tcg_tcx, page size globals, and possibly others; * kvm_init() changes the kvm_state global, cpu_interrupt_handler, and possibly others; * xen_init() changes the xen_xc global, and registers a change state handler. With the new accelerator QOM classes, initialization may now be split in two steps: * instance_init() will do basic initialization that doesn't affect any global state and don't need MachineState or MachineClass data. This will allow probing code to safely create multiple accelerator objects on the fly just for reporting host/accelerator capabilities, for example. * accel_init_machine()/init_machine() will save the accelerator object in MachineState, and do initialization steps which still affect global state, machine state, or that need data from MachineClass or MachineState. To clarify the difference between those two steps, rename init() to init_machine(). Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* accel: Move Xen registration code to xen-common.cEduardo Habkost2014-10-041-1/+24
| | | | | | | | | | | | | | | | Note that this has an user-visible side-effect: instead of reporting "Xen is not supported for this target", QEMU binaries not supporting Xen will report "xen accelerator does not exist". As xen_available() always return 1 when CONFIG_XEN is enabled, we don't need to set AccelClass.available anymore. xen_enabled() is not being removed yet, but only because vl.c is still using it. This also allows us to make xen_init() static. Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* xen: factor out common functionsWei Liu2014-05-071-0/+123
So common functions used by both HVM and PV are factored out from xen-all.c to xen-common.c. Finally rename xen-all.c to xen-hvm.c, as those functions are only useful to HVM guest. Create *-stub files and modify Makefile.target to reflect the changes. Signed-off-by: Wei Liu <wei.liu2@citrix.com> Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
