30 | Description: | ||
31 | Writing a device ID to this file will attempt to | ||
32 | dynamically add a new device ID to a PCI device driver. | ||
33 | This may allow the driver to support more hardware than | ||
34 | was included in the driver's static device ID support | ||
35 | table at compile time. The format for the device ID is: | ||
36 | VVVV DDDD SVVV SDDD CCCC MMMM PPPP. That is Vendor ID, | ||
37 | Device ID, Subsystem Vendor ID, Subsystem Device ID, | ||
38 | Class, Class Mask, and Private Driver Data. The Vendor ID | ||
39 | and Device ID fields are required, the rest are optional. | ||
40 | Upon successfully adding an ID, the driver will probe | ||
41 | for the device and attempt to bind to it. For example: | ||
42 | # echo "8086 10f5" > /sys/bus/pci/drivers/foo/new_id | ||

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. | ||

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. | ||

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. | ||

455 | <title>Frame Buffer Library</title> | ||
456 | |||
457 | <para> | ||
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. | ||

538 | <title>Serial Peripheral Interface (SPI)</title> | ||
539 | <para> | ||
540 | SPI is the "Serial Peripheral Interface", widely used with | ||
541 | embedded systems because it is a simple and efficient | ||
542 | interface: basically a multiplexed shift register. | ||
543 | Its three signal wires hold a clock (SCK, often in the range | ||
544 | of 1-20 MHz), a "Master Out, Slave In" (MOSI) data line, and | ||
545 | a "Master In, Slave Out" (MISO) data line. | ||
546 | SPI is a full duplex protocol; for each bit shifted out the | ||
547 | MOSI line (one per clock) another is shifted in on the MISO line. | ||
548 | Those bits are assembled into words of various sizes on the | ||
549 | way to and from system memory. | ||
550 | An additional chipselect line is usually active-low (nCS); | ||
551 | four signals are normally used for each peripheral, plus | ||
552 | sometimes an interrupt. | ||
553 | </para> | ||
554 | <para> | ||
555 | The SPI bus facilities listed here provide a generalized | ||
556 | interface to declare SPI busses and devices, manage them | ||
557 | according to the standard Linux driver model, and perform | ||
558 | input/output operations. | ||
559 | At this time, only "master" side interfaces are supported, | ||
560 | where Linux talks to SPI peripherals and does not implement | ||
561 | such a peripheral itself. | ||
562 | (Interfaces to support implementing SPI slaves would | ||
563 | necessarily look different.) | ||
564 | </para> | ||
565 | <para> | ||
566 | The programming interface is structured around two kinds of driver, | ||
567 | and two kinds of device. | ||
568 | A "Controller Driver" abstracts the controller hardware, which may | ||
569 | be as simple as a set of GPIO pins or as complex as a pair of FIFOs | ||
570 | connected to dual DMA engines on the other side of the SPI shift | ||
571 | register (maximizing throughput). Such drivers bridge between | ||
572 | whatever bus they sit on (often the platform bus) and SPI, and | ||
573 | expose the SPI side of their device as a | ||
574 | <structname>struct spi_master</structname>. | ||
575 | SPI devices are children of that master, represented as a | ||
576 | <structname>struct spi_device</structname> and manufactured from | ||
577 | <structname>struct spi_board_info</structname> descriptors which | ||
578 | are usually provided by board-specific initialization code. | ||
579 | A <structname>struct spi_driver</structname> is called a | ||
580 | "Protocol Driver", and is bound to a spi_device using normal | ||
581 | driver model calls. | ||
582 | </para> | ||
583 | <para> | ||
584 | The I/O model is a set of queued messages. Protocol drivers | ||
585 | submit one or more <structname>struct spi_message</structname> | ||
586 | objects, which are processed and completed asynchronously. | ||
587 | (There are synchronous wrappers, however.) Messages are | ||
588 | built from one or more <structname>struct spi_transfer</structname> | ||
589 | objects, each of which wraps a full duplex SPI transfer. | ||
590 | A variety of protocol tweaking options are needed, because | ||
591 | different chips adopt very different policies for how they | ||
592 | use the bits transferred with SPI. | ||

602 | <para> | ||
603 | I<superscript>2</superscript>C (or without fancy typography, "I2C") | ||
604 | is an acronym for the "Inter-IC" bus, a simple bus protocol which is | ||
605 | widely used where low data rate communications suffice. | ||
606 | Since it's also a licensed trademark, some vendors use another | ||
607 | name (such as "Two-Wire Interface", TWI) for the same bus. | ||
608 | I2C only needs two signals (SCL for clock, SDA for data), conserving | ||
609 | board real estate and minimizing signal quality issues. | ||
610 | Most I2C devices use seven bit addresses, and bus speeds of up | ||
611 | to 400 kHz; there's a high speed extension (3.4 MHz) that's not yet | ||
612 | found wide use. | ||
613 | I2C is a multi-master bus; open drain signaling is used to | ||

627 | On each I2C bus segment will be I2C devices represented by a | ||

629 | be bound to a <structname>struct i2c_driver</structname>, | ||
630 | which should follow the standard Linux driver model. | ||
631 | (At this writing, a legacy model is more widely used.) | ||
632 | There are functions to perform various I2C protocol operations; at | ||
633 | this writing all such functions are usable only from task context. | ||
634 | </para> | ||
635 | |||
636 | <para> | ||
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 | ||

1 | This README escorted the skystar2-driver rewriting procedure. It describes the | ||
2 | state of the new flexcop-driver set and some internals are written down here | ||
3 | too. | ||
4 | |||
5 | This document hopefully describes things about the flexcop and its | ||
6 | device-offsprings. Goal was to write an easy-to-write and easy-to-read set of | ||
7 | drivers based on the skystar2.c and other information. | ||
8 | |||
9 | Remark: flexcop-pci.c was a copy of skystar2.c, but every line has been | ||
10 | touched and rewritten. | ||
11 | |||
12 | History & News | ||
13 | ============== | ||
14 | 2005-04-01 - correct USB ISOC transfers (thanks to Vadim Catana) | ||
15 | |||
16 | |||
17 | |||
18 | |||
19 | General coding processing | ||
20 | ========================= | ||
21 | |||
22 | We should proceed as follows (as long as no one complains): | ||
23 | |||
24 | 0) Think before start writing code! | ||
25 | |||
26 | 1) rewriting the skystar2.c with the help of the flexcop register descriptions | ||
27 | and splitting up the files to a pci-bus-part and a flexcop-part. | ||
28 | The new driver will be called b2c2-flexcop-pci.ko/b2c2-flexcop-usb.ko for the | ||
29 | device-specific part and b2c2-flexcop.ko for the common flexcop-functions. | ||
30 | |||
31 | 2) Search for errors in the leftover of flexcop-pci.c (compare with pluto2.c | ||
32 | and other pci drivers) | ||
33 | |||
34 | 3) make some beautification (see 'Improvements when rewriting (refactoring) is | ||
35 | done') | ||
36 | |||
37 | 4) Testing the new driver and maybe substitute the skystar2.c with it, to reach | ||
38 | a wider tester audience. | ||
39 | |||
40 | 5) creating an usb-bus-part using the already written flexcop code for the pci | ||
41 | card. | ||
42 | |||
43 | Idea: create a kernel-object for the flexcop and export all important | ||
44 | functions. This option saves kernel-memory, but maybe a lot of functions have | ||
45 | to be exported to kernel namespace. | ||
46 | |||
47 | |||
48 | Current situation | ||
49 | ================= | ||
50 | |||
51 | 0) Done :) | ||
52 | 1) Done (some minor issues left) | ||
53 | 2) Done | ||
54 | 3) Not ready yet, more information is necessary | ||
55 | 4) next to be done (see the table below) | ||
56 | 5) USB driver is working (yes, there are some minor issues) | ||
57 | |||
58 | What seems to be ready? | ||
59 | ----------------------- | ||
60 | |||
61 | 1) Rewriting | ||
62 | 1a) i2c is cut off from the flexcop-pci.c and seems to work | ||
63 | 1b) moved tuner and demod stuff from flexcop-pci.c to flexcop-tuner-fe.c | ||
64 | 1c) moved lnb and diseqc stuff from flexcop-pci.c to flexcop-tuner-fe.c | ||
65 | 1e) eeprom (reading MAC address) | ||
66 | 1d) sram (no dynamic sll size detection (commented out) (using default as JJ told me)) | ||
67 | 1f) misc. register accesses for reading parameters (e.g. resetting, revision) | ||
68 | 1g) pid/mac filter (flexcop-hw-filter.c) | ||
69 | 1i) dvb-stuff initialization in flexcop.c (done) | ||
70 | 1h) dma stuff (now just using the size-irq, instead of all-together, to be done) | ||
71 | 1j) remove flexcop initialization from flexcop-pci.c completely (done) | ||
72 | 1l) use a well working dma IRQ method (done, see 'Known bugs and problems and TODO') | ||
73 | 1k) cleanup flexcop-files (remove unused EXPORT_SYMBOLs, make static from | ||
74 | non-static where possible, moved code to proper places) | ||
75 | |||
76 | 2) Search for errors in the leftover of flexcop-pci.c (partially done) | ||
77 | 5a) add MAC address reading | ||
78 | 5c) feeding of ISOC data to the software demux (format of the isochronous data | ||
79 | and speed optimization, no real error) (thanks to Vadim Catana) | ||
80 | |||
81 | What to do in the near future? | ||
82 | -------------------------------------- | ||
83 | (no special order here) | ||
84 | |||
85 | 5) USB driver | ||
86 | 5b) optimize isoc-transfer (submitting/killing isoc URBs when transfer is starting) | ||
87 | |||

118 | Known bugs and problems and TODO | ||
119 | -------------------------------- | ||
120 | |||
121 | 1g/h/l) when pid filtering is enabled on the pci card | ||
122 | |||
123 | DMA usage currently: | ||
124 | The DMA is splitted in 2 equal-sized subbuffers. The Flexcop writes to first | ||
125 | address and triggers an IRQ when it's full and starts writing to the second | ||
126 | address. When the second address is full, the IRQ is triggered again, and | ||
127 | the flexcop writes to first address again, and so on. | ||
128 | The buffersize of each address is currently 640*188 bytes. | ||
129 | |||
130 | Problem is, when using hw-pid-filtering and doing some low-bandwidth | ||
131 | operation (like scanning) the buffers won't be filled enough to trigger | ||
132 | the IRQ. That's why: | ||
133 | |||
134 | When PID filtering is activated, the timer IRQ is used. Every 1.97 ms the IRQ | ||
135 | is triggered. Is the current write address of DMA1 different to the one | ||
136 | during the last IRQ, then the data is passed to the demuxer. | ||
137 | |||
138 | There is an additional DMA-IRQ-method: packet count IRQ. This isn't | ||
139 | implemented correctly yet. | ||
140 | |||
141 | The solution is to disable HW PID filtering, but I don't know how the DVB | ||
142 | API software demux behaves on slow systems with 45MBit/s TS. | ||
143 | |||
144 | Solved bugs :) | ||
145 | -------------- | ||
146 | 1g) pid-filtering (somehow pid index 4 and 5 (EMM_PID and ECM_PID) aren't | ||
147 | working) | ||
148 | SOLUTION: also index 0 was affected, because net_translation is done for | ||
149 | these indexes by default | ||
150 | |||
151 | 5b) isochronous transfer does only work in the first attempt (for the Sky2PC | ||
152 | USB, Air2PC is working) SOLUTION: the flexcop was going asleep and never really | ||
153 | woke up again (don't know if this need fixes, see | ||
154 | flexcop-fe-tuner.c:flexcop_sleep) | ||
155 | |||
156 | NEWS: when the driver is loaded and unloaded and loaded again (w/o doing | ||
157 | anything in the while the driver is loaded the first time), no transfers take | ||
158 | place anymore. | ||
159 | |||
160 | Improvements when rewriting (refactoring) is done | ||
161 | ================================================= | ||
162 | |||
163 | - split sleeping of the flexcop (misc_204.ACPI3_sig = 1;) from lnb_control | ||
164 | (enable sleeping for other demods than dvb-s) | ||
165 | - add support for CableStar (stv0297 Microtune 203x/ALPS) (almost done, incompatibilities with the Nexus-CA) | ||
166 | |||
167 | Debugging | ||
168 | --------- | ||
169 | - add verbose debugging to skystar2.c (dump the reg_dw_data) and compare it | ||
170 | with this flexcop, this is important, because i2c is now using the | ||
171 | flexcop_ibi_value union from flexcop-reg.h (do you have a better idea for | ||
172 | that, please tell us so). | ||
173 | |||
174 | Everything which is identical in the following table, can be put into a common | ||
175 | flexcop-module. | ||
176 | |||
177 | PCI USB | ||
178 | ------------------------------------------------------------------------------- | ||
179 | Different: | ||
180 | Register access: accessing IO memory USB control message | ||
181 | I2C bus: I2C bus of the FC USB control message | ||
182 | Data transfer: DMA isochronous transfer | ||
183 | EEPROM transfer: through i2c bus not clear yet | ||
184 | |||
185 | Identical: | ||
186 | Streaming: accessing registers | ||
187 | PID Filtering: accessing registers | ||
188 | Sram destinations: accessing registers | ||
189 | Tuner/Demod: I2C bus | ||
190 | DVB-stuff: can be written for common use | ||
