187 \r
188 If Enabled is set to FALSE, the driver entity will not scan the channel. Note \r
189 that it will not prevent an operating system driver from scanning the channel.\r
190 \r
191 For most of today's controllers, MaxDevices will either be 1 or 2. For SATA \r
192 controllers, this value will always be 1. SATA configurations can contain SATA \r
193 port multipliers. SATA port multipliers behave like SATA bridges and can support\r
194 up to 16 devices on the other side. If a SATA port out of the IDE controller \r
195 is connected to a port multiplier, MaxDevices will be set to the number of SATA \r
196 devices that the port multiplier supports. Because today's port multipliers \r
197 support up to fifteen SATA devices, this number can be as large as fifteen. The IDE \r
198 bus driver is required to scan for the presence of port multipliers behind an SATA \r
199 controller and enumerate up to MaxDevices number of devices behind the port \r
200 multiplier. \r
201 \r
202 In this context, the devices behind a port multiplier constitute a channel. \r

262 Submits the device information to the IDE controller driver.\r
263\r
264 This function is used by the driver entity to pass detailed information about \r
265 a particular device to the IDE controller driver. The driver entity obtains \r
266 this information by issuing an ATA or ATAPI IDENTIFY_DEVICE command. IdentifyData\r
267 is the pointer to the response data buffer. The IdentifyData buffer is owned \r
268 by the driver entity, and the IDE controller driver must make a local copy \r
269 of the entire buffer or parts of the buffer as needed. The original IdentifyData \r
270 buffer pointer may not be valid when\r
271 \r
272 - EFI_IDE_CONTROLLER_INIT_PROTOCOL.CalculateMode() or\r
273 - EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode() is called at a later point.\r
274 \r
275 The IDE controller driver may consult various fields of EFI_IDENTIFY_DATA to \r
276 compute the optimum mode for the device. These fields are not limited to the \r
277 timing information. For example, an implementation of the IDE controller driver \r
278 may examine the vendor and type/mode field to match known bad drives. \r
279 \r
280 The driver entity may submit drive information in any order, as long as it \r
281 submits information for all the devices belonging to the enumeration group \r
282 before EFI_IDE_CONTROLLER_INIT_PROTOCOL.CalculateMode() is called for any device\r
283 in that enumeration group. If a device is absent, EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()\r
284 should be called with IdentifyData set to NULL. The IDE controller driver may \r
285 not have any other mechanism to know whether a device is present or not. Therefore, \r
286 setting IdentifyData to NULL does not constitute an error condition. \r

311 Disqualifies specific modes for an IDE device.\r
312\r
313 This function allows the driver entity or other drivers (such as platform \r
314 drivers) to reject certain timing modes and request the IDE controller driver\r
315 to recalculate modes. This function allows the driver entity and the IDE \r
316 controller driver to negotiate the timings on a per-device basis. This function \r
317 is useful in the case of drives that lie about their capabilities. An example \r
318 is when the IDE device fails to accept the timing modes that are calculated \r
319 by the IDE controller driver based on the response to the Identify Drive command.\r
320\r
321 If the driver entity does not want to limit the ATA timing modes and leave that \r
322 decision to the IDE controller driver, it can either not call this function for \r
323 the given device or call this function and set the Valid flag to FALSE for all \r
324 modes that are listed in EFI_ATA_COLLECTIVE_MODE.\r
325 \r
326 The driver entity may disqualify modes for a device in any order and any number \r
327 of times.\r
328 \r
329 This function can be called multiple times to invalidate multiple modes of the \r
330 same type (e.g., Programmed Input/Output [PIO] modes 3 and 4). See the ATA/ATAPI \r
331 specification for more information on PIO modes. \r
332 \r
333 For Serial ATA (SATA) controllers, this member function can be used to disqualify\r
334 a higher transfer rate mode on a given channel. For example, a platform driver\r
335 may inform the IDE controller driver to not use second-generation (Gen2) speeds \r
336 for a certain SATA drive.\r

361 Returns the information about the optimum modes for the specified IDE device.\r
362\r
363 This function is used by the driver entity to obtain the optimum ATA modes for\r
364 a specific device. The IDE controller driver takes into account the following \r
365 while calculating the mode:\r
366 - The IdentifyData inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()\r
367 - The BadModes inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode()\r
368\r
369 The driver entity is required to call EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData() \r
370 for all the devices that belong to an enumeration group before calling \r
371 EFI_IDE_CONTROLLER_INIT_PROTOCOL.CalculateMode() for any device in the same group. \r
372 \r
373 The IDE controller driver will use controller- and possibly platform-specific \r
374 algorithms to arrive at SupportedModes. The IDE controller may base its \r
375 decision on user preferences and other considerations as well. This function \r
376 may be called multiple times because the driver entity may renegotiate the mode \r
377 with the IDE controller driver using EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode().\r
378 \r
379 The driver entity may collect timing information for various devices in any \r
380 order. The driver entity is responsible for making sure that all the dependencies\r
381 are satisfied. For example, the SupportedModes information for device A that \r
382 was previously returned may become stale after a call to \r
383 EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode() for device B.\r
384 \r
385 The buffer SupportedModes is allocated by the callee because the caller does \r
386 not necessarily know the size of the buffer. The type EFI_ATA_COLLECTIVE_MODE \r
387 is defined in a way that allows for future extensibility and can be of variable \r
388 length. This memory pool should be deallocated by the caller when it is no \r
389 longer necessary. \r
390 \r
391 The IDE controller driver for a Serial ATA (SATA) controller can use this \r
392 member function to force a lower speed (first-generation [Gen1] speeds on a \r
393 second-generation [Gen2]-capable hardware). The IDE controller driver can \r
394 also allow the driver entity to stay with the speed that has been negotiated \r
