|
|---|
| 20 | *
|
|---|
| 21 | * The PDM handles devices and their drivers in a flexible and dynamic manner.
|
|---|
| 22 | *
|
|---|
| 23 | * VirtualBox is designed to be very configurable, i.e. the ability to select
|
|---|
| 24 | * virtual devices and configure them uniquely for a VM. For this reason
|
|---|
| 25 | * virtual devices are not statically linked with the VMM but loaded, linked and
|
|---|
| 26 | * instantiated at runtime by PDM using the information found in the
|
|---|
| 27 | * Configuration Manager (CFGM).
|
|---|
| 28 | *
|
|---|
| 29 | * While the chief purpose of PDM is to manager of devices their drivers, it
|
|---|
| 30 | * also serves as somewhere to put usful things like cross context queues, cross
|
|---|
| 31 | * context synchronization (like critsect), VM centric thread management,
|
|---|
| 32 | * asynchronous I/O framework, and so on.

|
|---|
| 40 | *
|
|---|
| 41 | * Devices register themselves when the module containing them is loaded. PDM
|
|---|
| 42 | * will call the entry point 'VBoxDevicesRegister' when loading a device module.
|
|---|
| 43 | * The device module will then use the supplied callback table to check the VMM
|
|---|
| 44 | * version and to register its devices. Each device has an unique name (within
|
|---|
| 45 | * the VM configuration anyway). The name is not only used in PDM, but also in
|
|---|
| 46 | * CFGM to organize device and device instance settings, and by anyone who wants
|
|---|
| 47 | * to talk to a specific device instance.
|
|---|
| 48 | *
|
|---|
| 49 | * When all device modules have been successfully loaded PDM will instantiate
|
|---|
| 50 | * those devices which are configured for the VM. Note that a device may have
|
|---|
| 51 | * more than one instance, take network adaptors as an example. When
|
|---|
| 52 | * instantiating a device PDM provides device instance memory and a callback
|
|---|
| 53 | * table (aka Device Helpers / DevHlp) with the VM APIs which the device
|
|---|
| 54 | * instance is trusted with.
|
|---|
| 55 | *
|
|---|
| 56 | * Some devices are trusted devices, most are not. The trusted devices are an
|
|---|
| 57 | * integrated part of the VM and can obtain the VM handle, thus enabling them to
|
|---|
| 58 | * call any VM API. Untrusted devices can only use the callbacks provided
|
|---|
| 59 | * during device instantiation.
|
|---|
| 60 | *
|
|---|
| 61 | * The main purpose in having DevHlps rather than just giving all the devices
|
|---|
| 62 | * the VM handle and let them call the internal VM APIs directly, is both to
|
|---|
| 63 | * create a binary interface that can be supported across releases and to
|
|---|
| 64 | * create a barrier between devices and the VM. (The trusted / untrusted bit
|
|---|
| 65 | * hasn't turned out to be of much use btw., but it's easy to maintain so there
|
|---|
| 66 | * isn't any point in removing it.)
|
|---|
| 67 | *
|
|---|
| 68 | * A device can provide a ring-0 and/or a raw-mode context extension to improve
|
|---|
| 69 | * the VM performance by handling exits and traps (respectively) without
|
|---|
| 70 | * requiring context switches (to ring-3). Callbacks for MMIO and I/O ports
|
|---|
| 71 | * need to be registered specifically for the additional contexts for this to
|
|---|
| 72 | * make sense. Also, the device has to be trusted to be loaded into R0/RC
|
|---|
| 73 | * because of the extra privilege it entails. Note that raw-mode code and data
|
|---|
| 74 | * will be subject to relocation.

| 77 | * @subsection sec_pdm_dev_pci PCI Devices
|
|---|
| 78 | *
|
|---|
| 79 | * A PDM device usually registers one a PCI device during it's instantiation,
|
|---|
| 80 | * legacy devices may register zero, while a few (currently none) more
|
|---|
| 81 | * complicated devices may register multiple PCI functions or devices.
|
|---|
| 82 | *
|
|---|
| 83 | * The bus, device and function assignments can either be done explictly via the
|
|---|
| 84 | * configuration or the registration call, or it can be left up to the PCI bus.
|
|---|
| 85 | * The typical VBox configuration construct (ConsoleImpl2.cpp) will do explict
|
|---|
| 86 | * assignments for all devices it's BusAssignmentManager class knows about.
|
|---|
| 87 | *
|
|---|
| 88 | * For explict CFGM style configuration, the "PCIBusNo", "PCIDeviceNo", and
|
|---|
| 89 | * "PCIFunctionNo" values in the PDM device instance configuration (not the
|
|---|
| 90 | * "config" subkey, but the top level one) will be picked up for the primary PCI
|
|---|
| 91 | * device. The primary PCI configuration is by default the first one, but this
|
|---|
| 92 | * can be controlled using the @a idxDevCfg parameter of the
|
|---|
| 93 | * PDMDEVHLPR3::pfnPCIRegister method. For subsequent configuration (@a
|
|---|
| 94 | * idxDevCfg > 0) the values are taken from the "PciDevNN" subkey, where "NN" is
|
|---|
| 95 | * replaced by the @a idxDevCfg value.
|
|---|
| 96 | *
|
|---|
| 97 | * There's currently a limit of 256 PCI devices per PDM device.
|
|---|
| 98 | *
|
|---|
| 99 | *
|
|---|
| 100 | * @subsection sec_pdm_dev_new New Style (6.1)
|
|---|
| 101 | *
|
|---|
| 102 | * VBox 6.1 changes the PDM interface for devices and they have to be converted
|
|---|
| 103 | * to the new style to continue working (see @bugref{9218}).
|
|---|
| 104 | *
|
|---|
| 105 | * Steps for converting a PDM device to the new style:
|
|---|
| 106 | *
|
|---|
| 107 | * - State data needs to be split into shared, ring-3, ring-0 and raw-mode
|
|---|
| 108 | * structures. The shared structure shall contains absolutely no pointers.
|
|---|
| 109 | *
|
|---|
| 110 | * - Context specific typedefs ending in CC for the structure and pointer to
|
|---|
| 111 | * it are required (copy & edit the PRTCSTATECC stuff).
|
|---|
| 112 | * The pointer to a context specific structure is obtained using the
|
|---|
| 113 | * PDMINS_2_DATA_CC macro. The PDMINS_2_DATA macro gets the shared one.
|
|---|
| 114 | *
|
|---|
| 115 | * - Update the registration structure with sizeof the new structures.
|
|---|
| 116 | *
|
|---|
| 117 | * - MMIO handlers to FNIOMMMIONEWREAD and FNIOMMMIONEWRITE form, take care renaming
|
|---|
| 118 | * GCPhys to off and really treat it as an offset. Return status is VBOXSTRICTRC,
|
|---|
| 119 | * which should be propagated to worker functions as far as possible.
|
|---|
| 120 | *
|
|---|
| 121 | * - I/O handlers to FNIOMIOPORTNEWIN and FNIOMIOPORTNEWOUT form, take care renaming
|
|---|
| 122 | * uPort/Port to offPort and really treat it as an offset. Return status is
|
|---|
| 123 | * VBOXSTRICTRC, which should be propagated to worker functions as far as possible.
|
|---|
| 124 | *
|
|---|
| 125 | * - MMIO and I/O port registration must be converted, handles stored in the shared structure.
|
|---|
| 126 | *
|
|---|
| 127 | * - PCI devices must also update the I/O region registration and corresponding
|
|---|
| 128 | * mapping callback. The latter is generally not needed any more, as the PCI
|
|---|
| 129 | * bus does the mapping and unmapping using the handle passed to it during registration.
|
|---|
| 130 | *
|
|---|
| 131 | * - If the device contains ring-0 or raw-mode optimizations:
|
|---|
| 132 | * - Make sure to replace any R0Enabled, GCEnabled, and RZEnabled with
|
|---|
| 133 | * pDevIns->fR0Enabled and pDevIns->fRCEnabled. Removing CFGM reading and
|
|---|
| 134 | * validation of such options as well as state members for them.
|
|---|
| 135 | * - Callbacks for ring-0 and raw-mode are registered in a context contructor.
|
|---|
| 136 | * Setting up of non-default critical section handling needs to be repeated
|
|---|
| 137 | * in the ring-0/raw-mode context constructor too. See for instance
|
|---|
| 138 | * e1kRZConstruct().
|
|---|
| 139 | *
|
|---|
| 140 | * - Convert all PDMCritSect calls to PDMDevHlpCritSect.
|
|---|
| 141 | * Note! pDevIns should be passed as parameter rather than put in pThisCC.
|
|---|
| 142 | *
|
|---|
| 143 | * - Convert all timers to the handle based ones.
|
|---|
| 144 | *
|
|---|
| 145 | * - Convert all queues to the handle based ones or tasks.
|
|---|
| 146 | *
|
|---|
| 147 | * - Set the PDM_DEVREG_FLAGS_NEW_STYLE in the registration structure.
|
|---|
| 148 | * (Functionally, this only makes a difference for PDMDevHlpSetDeviceCritSect
|
|---|
| 149 | * behavior, but it will become mandatory once all devices has been
|
|---|
| 150 | * converted.)
|
|---|
| 151 | *
|
|---|
| 152 | * - Convert all CFGMR3Xxxx calls to pHlp->pfnCFGMXxxx.
|
|---|
| 153 | *
|
|---|
| 154 | * - Convert all SSMR3Xxxx calls to pHlp->pfnSSMXxxx.
|
|---|
| 155 | *
|
|---|
| 156 | * - Ensure that CFGM values and nodes are validated using PDMDEV_VALIDATE_CONFIG_RETURN()
|
|---|
| 157 | *
|
|---|
| 158 | * - Ensure that the first statement in the constructors is
|
|---|
| 159 | * @code
|
|---|
| 160 | PDMDEV_CHECK_VERSIONS_RETURN(pDevIns);
|
|---|
| 161 | @endcode
|
|---|
| 162 | * There shall be absolutely nothing preceeding that and it is mandatory.
|
|---|
| 163 | *
|
|---|
| 164 | * - Ensure that the first statement in the destructors is
|
|---|
| 165 | * @code
|
|---|
| 166 | PDMDEV_CHECK_VERSIONS_RETURN_QUIET(pDevIns);
|
|---|
| 167 | @endcode
|
|---|
| 168 | * There shall be absolutely nothing preceeding that and it is mandatory.
|
|---|
| 169 | *
|
|---|
| 170 | * - Use 'nm -u' (tools/win.amd64/mingw-w64/r1/bin/nm.exe on windows) to check
|
|---|
| 171 | * for VBoxVMM and VMMR0 function you forgot to convert to device help calls
|
|---|
| 172 | * or would need adding as device helpers or something.

|
|---|
| 176 | *
|
|---|
| 177 | * Several kinds of devices interacts with the VMM and/or other device and PDM
|
|---|
| 178 | * will work like a mediator for these. The typical pattern is that the device
|
|---|
| 179 | * calls a special registration device helper with a set of callbacks, PDM
|
|---|
| 180 | * responds by copying this and providing a pointer to a set helper callbacks
|
|---|
| 181 | * for that particular kind of device. Unlike interfaces where the callback
|
|---|
| 182 | * table pointer is used a 'this' pointer, these arrangements will use the
|
|---|
| 183 | * device instance pointer (PPDMDEVINS) as a kind of 'this' pointer.
|
|---|
| 184 | *
|
|---|
| 185 | * For an example of this kind of setup, see the PIC. The PIC registers itself
|
|---|
| 186 | * by calling PDMDEVHLPR3::pfnPICRegister. PDM saves the device instance,
|
|---|
| 187 | * copies the callback tables (PDMPICREG), resolving the ring-0 and raw-mode
|
|---|
| 188 | * addresses in the process, and hands back the pointer to a set of helper
|
|---|
| 189 | * methods (PDMPICHLPR3). The PCI device then queries the ring-0 and raw-mode
|
|---|
| 190 | * helpers using PDMPICHLPR3::pfnGetR0Helpers and PDMPICHLPR3::pfnGetRCHelpers.
|
|---|
| 191 | * The PCI device repeats ths pfnGetRCHelpers call in it's relocation method
|
|---|
| 192 | * since the address changes when RC is relocated.

| 196 | * @section sec_pdm_usbdev The Pluggable USB Devices
|
|---|
| 197 | *
|
|---|
| 198 | * USB devices are handled a little bit differently than other devices. The
|
|---|
| 199 | * general concepts wrt. pluggability are mostly the same, but the details
|
|---|
| 200 | * varies. The registration entry point is 'VBoxUsbRegister', the device
|
|---|
| 201 | * instance is PDMUSBINS and the callbacks helpers are different. Also, USB
|
|---|
| 202 | * device are restricted to ring-3 and cannot have any ring-0 or raw-mode
|
|---|
| 203 | * extensions (at least not yet).
|
|---|
| 204 | *
|
|---|
| 205 | * The way USB devices work differs greatly from other devices though since they
|
|---|
| 206 | * aren't attaches directly to the PCI/ISA/whatever system buses but via a
|
|---|
| 207 | * USB host control (OHCI, UHCI or EHCI). USB devices handle USB requests
|
|---|
| 208 | * (URBs) and does not register I/O ports, MMIO ranges or PCI bus
|
|---|
| 209 | * devices/functions.

|
|---|
| 214 | * @section sec_pdm_drv The Pluggable Drivers
|
|---|
| 215 | *
|
|---|
| 216 | * The VM devices are often accessing host hardware or OS facilities. For most
|
|---|
| 217 | * devices these facilities can be abstracted in one or more levels. These
|
|---|
| 218 | * abstractions are called drivers.
|
|---|
| 219 | *
|
|---|
| 220 | * For instance take a DVD/CD drive. This can be connected to a SCSI
|
|---|
| 221 | * controller, an ATA controller or a SATA controller. The basics of the DVD/CD
|
|---|
| 222 | * drive implementation remains the same - eject, insert, read, seek, and such.
|
|---|
| 223 | * (For the scsi SCSCI, you might want to speak SCSI directly to, but that can of
|
|---|
| 224 | * course be fixed - see SCSI passthru.) So, it
|
|---|
| 225 | * makes much sense to have a generic CD/DVD driver which implements this.
|
|---|
| 226 | *
|
|---|
| 227 | * Then the media 'inserted' into the DVD/CD drive can be a ISO image, or it can
|
|---|
| 228 | * be read from a real CD or DVD drive (there are probably other custom formats
|
|---|
| 229 | * someone could desire to read or construct too). So, it would make sense to
|
|---|
| 230 | * have abstracted interfaces for dealing with this in a generic way so the
|
|---|
| 231 | * cdrom unit doesn't have to implement it all. Thus we have created the
|
|---|
| 232 | * CDROM/DVD media driver family.
|
|---|
| 233 | *
|
|---|
| 234 | * So, for this example the IDE controller #1 (i.e. secondary) will have
|
|---|
| 235 | * the DVD/CD Driver attached to it's LUN #0 (master). When a media is mounted
|
|---|
| 236 | * the DVD/CD Driver will have a ISO, HostDVD or RAW (media) Driver attached.
|
|---|
| 237 | *
|
|---|
| 238 | * It is possible to configure many levels of drivers inserting filters, loggers,
|
|---|
| 239 | * or whatever you desire into the chain. We're using this for network sniffing,
|
|---|
| 240 | * for instance.
|
|---|
| 241 | *
|
|---|
| 242 | * The drivers are loaded in a similar manner to that of a device, namely by
|
|---|
| 243 | * iterating a keyspace in CFGM, load the modules listed there and call
|
|---|
| 244 | * 'VBoxDriversRegister' with a callback table.

|
|---|
| 250 | *
|
|---|
| 251 | * The pluggable drivers and devices expose one standard interface (callback
|
|---|
| 252 | * table) which is used to construct, destruct, attach, detach,( ++,) and query
|
|---|
| 253 | * other interfaces. A device will query the interfaces required for it's
|
|---|
| 254 | * operation during init and hot-plug. PDM may query some interfaces during
|
|---|
| 255 | * runtime mounting too.
|
|---|
| 256 | *
|
|---|
| 257 | * An interface here means a function table contained within the device or
|
|---|
| 258 | * driver instance data. Its methods are invoked with the function table pointer
|
|---|
| 259 | * as the first argument and they will calculate the address of the device or
|
|---|
| 260 | * driver instance data from it. (This is one of the aspects which *might* have
|
|---|
| 261 | * been better done in C++.)

| 295 | *
|
|---|
| 296 | * The PDM Critical Section API is currently building on the IPRT API with the
|
|---|
| 297 | * same name. It adds the possibility to use critical sections in ring-0 and
|
|---|
| 298 | * raw-mode as well as in ring-3. There are certain restrictions on the RC and
|
|---|
| 299 | * R0 usage though since we're not able to wait on it, nor wake up anyone that
|
|---|
| 300 | * is waiting on it. These restrictions origins with the use of a ring-3 event
|
|---|
| 301 | * semaphore. In a later incarnation we plan to replace the ring-3 event
|
|---|
| 302 | * semaphore with a ring-0 one, thus enabling us to wake up waiters while
|
|---|
| 303 | * exectuing in ring-0 and making the hardware assisted execution mode more
|
|---|
| 304 | * efficient. (Raw-mode won't benefit much from this, naturally.)

| 312 | * ring-3 by EMT, and optionally forcing a delayed or ASAP return to ring-3. The
|
|---|
| 313 | * queues can also be run on a timer basis as an alternative to the ASAP thing.

|

| 323 | *
|
|---|
| 324 | * The PDM Task API is for flagging a task for execution at a later point when
|
|---|
| 325 | * we're back in ring-3, optionally forcing the ring-3 return to happen ASAP.
|
|---|
| 326 | * As you can see the concept is similar to queues only simpler.
|
|---|
| 327 | *
|
|---|
| 328 | * A task can also be scheduled by another thread (a I/O worker for instance) as
|
|---|
| 329 | * a mean of getting something done in EMT.

|
|---|
| 334 | * @subsection sec_pdm_thread Thread
|
|---|
| 335 | *
|
|---|
| 336 | * The PDM Thread API is there to help devices and drivers manage their threads
|
|---|
| 337 | * correctly wrt. power on, suspend, resume, power off and destruction.
|
|---|
| 338 | *
|
|---|
| 339 | * The general usage pattern for threads in the employ of devices and drivers is
|
|---|
| 340 | * that they shuffle data or requests while the VM is running and stop doing
|
|---|
| 341 | * this when the VM is paused or powered down. Rogue threads running while the
|
|---|
| 342 | * VM is paused can cause the state to change during saving or have other
|
|---|
| 343 | * unwanted side effects. The PDM Threads API ensures that this won't happen.
