220 <title>Frame Buffer Library</title>
221
222 <para>
223 The frame buffer drivers depend heavily on four data structures.
224 These structures are declared in include/linux/fb.h. They are
225 fb_info, fb_var_screeninfo, fb_fix_screeninfo and fb_monospecs.
226 The last three can be made available to and from userland.
227 </para>
228
229 <para>
230 fb_info defines the current state of a particular video card.
231 Inside fb_info, there exists a fb_ops structure which is a
232 collection of needed functions to make fbdev and fbcon work.
233 fb_info is only visible to the kernel.
234 </para>
235
236 <para>
237 fb_var_screeninfo is used to describe the features of a video card
238 that are user defined. With fb_var_screeninfo, things such as
239 depth and the resolution may be defined.
240 </para>
241
242 <para>
243 The next structure is fb_fix_screeninfo. This defines the
244 properties of a card that are created when a mode is set and can't
245 be changed otherwise. A good example of this is the start of the
246 frame buffer memory. This "locks" the address of the frame buffer
247 memory, so that it cannot be changed or moved.
248 </para>
249
250 <para>
251 The last structure is fb_monospecs. In the old API, there was
252 little importance for fb_monospecs. This allowed for forbidden things
253 such as setting a mode of 800x600 on a fix frequency monitor. With
254 the new API, fb_monospecs prevents such things, and if used
255 correctly, can prevent a monitor from being cooked. fb_monospecs
256 will not be useful until kernels 2.5.x.

303 <title>Serial Peripheral Interface (SPI)</title>
304 <para>
305 SPI is the "Serial Peripheral Interface", widely used with
306 embedded systems because it is a simple and efficient
307 interface: basically a multiplexed shift register.
308 Its three signal wires hold a clock (SCK, often in the range
309 of 1-20 MHz), a "Master Out, Slave In" (MOSI) data line, and
310 a "Master In, Slave Out" (MISO) data line.
311 SPI is a full duplex protocol; for each bit shifted out the
312 MOSI line (one per clock) another is shifted in on the MISO line.
313 Those bits are assembled into words of various sizes on the
314 way to and from system memory.
315 An additional chipselect line is usually active-low (nCS);
316 four signals are normally used for each peripheral, plus
317 sometimes an interrupt.
318 </para>
319 <para>
320 The SPI bus facilities listed here provide a generalized
321 interface to declare SPI busses and devices, manage them
322 according to the standard Linux driver model, and perform
323 input/output operations.
324 At this time, only "master" side interfaces are supported,
325 where Linux talks to SPI peripherals and does not implement
326 such a peripheral itself.
327 (Interfaces to support implementing SPI slaves would
328 necessarily look different.)
329 </para>
330 <para>
331 The programming interface is structured around two kinds of driver,
332 and two kinds of device.
333 A "Controller Driver" abstracts the controller hardware, which may
334 be as simple as a set of GPIO pins or as complex as a pair of FIFOs
335 connected to dual DMA engines on the other side of the SPI shift
336 register (maximizing throughput). Such drivers bridge between
337 whatever bus they sit on (often the platform bus) and SPI, and
338 expose the SPI side of their device as a
339 <structname>struct spi_master</structname>.
340 SPI devices are children of that master, represented as a
341 <structname>struct spi_device</structname> and manufactured from
342 <structname>struct spi_board_info</structname> descriptors which
343 are usually provided by board-specific initialization code.
344 A <structname>struct spi_driver</structname> is called a
345 "Protocol Driver", and is bound to a spi_device using normal
346 driver model calls.
347 </para>
348 <para>
349 The I/O model is a set of queued messages. Protocol drivers
350 submit one or more <structname>struct spi_message</structname>
351 objects, which are processed and completed asynchronously.
352 (There are synchronous wrappers, however.) Messages are
353 built from one or more <structname>struct spi_transfer</structname>
354 objects, each of which wraps a full duplex SPI transfer.
355 A variety of protocol tweaking options are needed, because
356 different chips adopt very different policies for how they
357 use the bits transferred with SPI.

368 I<superscript>2</superscript>C (or without fancy typography, "I2C")
369 is an acronym for the "Inter-IC" bus, a simple bus protocol which is
370 widely used where low data rate communications suffice.
371 Since it's also a licensed trademark, some vendors use another
372 name (such as "Two-Wire Interface", TWI) for the same bus.
373 I2C only needs two signals (SCL for clock, SDA for data), conserving
374 board real estate and minimizing signal quality issues.
375 Most I2C devices use seven bit addresses, and bus speeds of up
376 to 400 kHz; there's a high speed extension (3.4 MHz) that's not yet
377 found wide use.
378 I2C is a multi-master bus; open drain signaling is used to
379 arbitrate between masters, as well as to handshake and to
380 synchronize clocks from slower clients.
381 </para>
382
383 <para>
384 The Linux I2C programming interfaces support only the master
385 side of bus interactions, not the slave side.
386 The programming interface is structured around two kinds of driver,
387 and two kinds of device.
388 An I2C "Adapter Driver" abstracts the controller hardware; it binds
389 to a physical device (perhaps a PCI device or platform_device) and
390 exposes a <structname>struct i2c_adapter</structname> representing
391 each I2C bus segment it manages.
392 On each I2C bus segment will be I2C devices represented by a
393 <structname>struct i2c_client</structname>. Those devices will
394 be bound to a <structname>struct i2c_driver</structname>,
395 which should follow the standard Linux driver model.
396 (At this writing, a legacy model is more widely used.)
397 There are functions to perform various I2C protocol operations; at
398 this writing all such functions are usable only from task context.
399 </para>
400
401 <para>
402 The System Management Bus (SMBus) is a sibling protocol. Most SMBus
403 systems are also I2C conformant. The electrical constraints are
404 tighter for SMBus, and it standardizes particular protocol messages
405 and idioms. Controllers that support I2C can also support most
406 SMBus operations, but SMBus controllers don't support all the protocol
407 options that an I2C controller will.
408 There are functions to perform various SMBus protocol operations,
409 either using I2C primitives or by issuing SMBus commands to
410 i2c_adapter devices which don't support those I2C operations.

458 The frame buffer drivers depend heavily on four data structures.
459 These structures are declared in include/linux/fb.h. They are
460 fb_info, fb_var_screeninfo, fb_fix_screeninfo and fb_monospecs.
461 The last three can be made available to and from userland.
462 </para>
463
464 <para>
465 fb_info defines the current state of a particular video card.
466 Inside fb_info, there exists a fb_ops structure which is a
467 collection of needed functions to make fbdev and fbcon work.
468 fb_info is only visible to the kernel.
469 </para>
470
471 <para>
472 fb_var_screeninfo is used to describe the features of a video card
473 that are user defined. With fb_var_screeninfo, things such as
474 depth and the resolution may be defined.
475 </para>
476
477 <para>
478 The next structure is fb_fix_screeninfo. This defines the
479 properties of a card that are created when a mode is set and can't
480 be changed otherwise. A good example of this is the start of the
481 frame buffer memory. This "locks" the address of the frame buffer
482 memory, so that it cannot be changed or moved.
483 </para>
484
485 <para>
486 The last structure is fb_monospecs. In the old API, there was
487 little importance for fb_monospecs. This allowed for forbidden things
488 such as setting a mode of 800x600 on a fix frequency monitor. With
489 the new API, fb_monospecs prevents such things, and if used
490 correctly, can prevent a monitor from being cooked. fb_monospecs
491 will not be useful until kernels 2.5.x.

637 The System Management Bus (SMBus) is a sibling protocol. Most SMBus
638 systems are also I2C conformant. The electrical constraints are
639 tighter for SMBus, and it standardizes particular protocol messages
640 and idioms. Controllers that support I2C can also support most
641 SMBus operations, but SMBus controllers don't support all the protocol
642 options that an I2C controller will.
643 There are functions to perform various SMBus protocol operations,
644 either using I2C primitives or by issuing SMBus commands to
645 i2c_adapter devices which don't support those I2C operations.

36Another feature of the driver is misc device called "freefall" that
37acts similar to /dev/rtc and reacts on free-fall interrupts received
38from the device. It supports blocking operations, poll/select and
39fasync operation modes. You must read 1 bytes from the device. The
40result is number of free-fall interrupts since the last successful
41read (or 255 if number of interrupts would not fit).

3Improve support for multiple security contexts to the same server. We
4used to use the same "vcnumber" for all connections which could cause
5the server to treat subsequent connections, especially those that
6are authenticated as guest, as reconnections, invalidating the earlier
7user's smb session. This fix allows cifs to mount multiple times to the
8same server with different userids without risking invalidating earlier
9established security contexts.
