b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * VBox is designed to be very configurable, i.e. the ability to select
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * virtual devices and configure them uniquely for a VM. For this reason
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * virtual devices are not statically linked with the VMM but loaded and
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * linked at runtime thru the Configuration Manager (CFGM). PDM will use
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * CFGM to enumerate devices which needs loading and instantiation.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * @section sec_pdm_dev The Pluggable Device
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * Devices register themselves when the module containing them is loaded.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * PDM will call an entry point 'VBoxDevicesRegister' when loading a device
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * module. The device module will then use the supplied callback table to
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * check the VMM version and to register its devices. Each device have an
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * unique (for the configured VM) name (string). The name is not only used
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * in PDM but in CFGM - to organize device and device instance settings - and
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * by anyone who wants to do ioctls to the device.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * When all device modules have been successfully loaded PDM will instantiate
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * those devices which are configured for the VM. Mark that this might mean
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * creating several instances of some devices. When instantiating a device
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * PDM provides device instance memory and a callback table with the VM APIs
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * which the device instance is trusted with.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * Some devices are trusted devices, most are not. The trusted devices are
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * an integrated part of the VM and can obtain the VM handle from their
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * device instance handles, thus enabling them to call any VM api. Untrusted
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * devices are can only use the callbacks provided during device
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * instantiation.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * The guest context extention (optional) of a device is initialized as part
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * of the GC init. A device marks in it's registration structure that it have
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * a GC part, in which module and which name the entry point have. PDM will
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * use its loader facilities to load this module into GC and to find the
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * specified entry point.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * When writing a GC extention the programmer must keep in mind that this
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * code will be relocated, so that using global/static pointer variables
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * won't work.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * @section sec_pdm_drv The Pluggable Drivers
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * The VM devices are often accessing host hardware or OS facilities. For
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * most devices these facilities can be abstracted in one or more levels.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * These abstractions are called drivers.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * For instance take a DVD/CD drive. This can be connected to a SCSI
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * controller, EIDE controller or SATA controller. The basics of the
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * DVD/CD drive implementation remains the same - eject, insert,
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * read, seek, and such. (For the scsi case, you might wanna speak SCSI
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * directly to, but that can of course be fixed.) So, it makes much sense to
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * have a generic CD/DVD driver which implements this.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * Then the media 'inserted' into the DVD/CD drive can be a ISO image, or
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * it can be read from a real CD or DVD drive (there are probably other
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * custom formats someone could desire to read or construct too). So, it
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * would make sense to have abstracted interfaces for dealing with this
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * in a generic way so the cdrom unit doesn't have to implement it all.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * Thus we have created the CDROM/DVD media driver family.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * So, for this example the IDE controller #1 (i.e. secondary) will have
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * the DVD/CD Driver attached to it's LUN #0 (master). When a media is mounted
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * the DVD/CD Driver will have a ISO, NativeCD, NativeDVD or RAW (media) Driver
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * attached.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * It is possible to configure many levels of drivers inserting filters, loggers,
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * or whatever you desire into the chain.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * @subsection sec_pdm_drv_interfaces Interfaces
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * The pluggable drivers exposes one standard interface (callback table) which
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * is used to construct, destruct, attach, detach, and query other interfaces.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * A device will query the interfaces required for it's operation during init
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * and hotplug. PDM will query some interfaces during runtime mounting too.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * ... list interfaces ...
