V4L/DVB (4228a): pvrusb2 to kernel 2.6.18
Implement V4L2 driver for the Hauppauge PVR USB2 TV tuner. The Hauppauge PVR USB2 is a USB connected TV tuner with an embedded cx23416 hardware MPEG2 encoder. There are two major variants of this device; this driver handles both. Any V4L2 application which understands MPEG2 video stream data should be able to work with this device.

11 This is a video4linux driver for Conexant 23416 based

14 To compile this driver as a module, choose M here: the
15 module will be called pvrusb2

23 This option enables inclusion of additional logic to operate
24 newer WinTV-PVR USB2 devices whose model number is of the
25 form "24xxx" (leading prefix of "24" followed by 3 digits).
26 To see if you may need this option, examine the white
27 sticker on the underside of your device. Enabling this
28 option will not harm support for older devices, however it
29 is a separate option because of the experimental nature of
30 this new feature.
31
32 If you are in doubt, say N.
33
34 Note: This feature is _very_ experimental. You have been
35 warned.

42 This option enables the operation of a sysfs based
43 interface for query and control of the pvrusb2 driver.
44
45 This is not generally needed for v4l applications,
46 although certain applications are optimized to take
47 advantage of this feature.
48
49 If you are in doubt, say Y.
50
51 Note: This feature is experimental and subject to change.

56 ---help---
57 This option enables the inclusion of a debug interface
58 in the pvrusb2 driver, hosted through sysfs.
59
60 You do not need to select this option unless you plan
61 on debugging the driver or performing a manual firmware
62 extraction.

162 The encoder seems to speak entirely using blocks 32 bit words.
163 In ivtv driver terms, this is a mailbox which we populate with
164 data and watch what the hardware does with it. The first word
165 is a set of flags used to control the transaction, the second
166 word is the command to execute, the third byte is zero (ivtv
167 driver suggests that this is some kind of return value), and
168 the fourth byte is a specified timeout (windows driver always
169 uses 0x00060000 except for one case when it is zero). All
170 successive words are the argument words for the command.
171
172 First, write out the entire set of words, with the first word
173 being zero.
174
175 Next, write out just the first word again, but set it to
176 IVTV_MBOX_DRIVER_DONE | IVTV_DRIVER_BUSY this time (which
177 probably means "go").
178
179 Next, read back 16 words as status. Check the first word,
180 which should have IVTV_MBOX_FIRMWARE_DONE set. If however
181 that bit is not set, then the command isn't done so repeat the
182 read.
183
184 Next, read back 32 words and compare with the original
185 arugments. Hopefully they will match.
186
187 Finally, write out just the first word again, but set it to
188 0x0 this time (which probably means "idle").

1059 This single function is key to pretty much everything. The pvrusb2
1060 device can logically be viewed as a series of subsystems which can be
1061 stopped / started or unconfigured / configured. To get things streaming,
1062 one must configure everything and start everything, but there may be
1063 various reasons over time to deconfigure something or stop something.
1064 This function handles all of this activity. Everything EVERYWHERE that
1065 must affect a subsystem eventually comes here to do the work.
1066
1067 The current state of all subsystems is represented by a single bit mask,
1068 known as subsys_enabled_mask. The bit positions are defined by the
1069 PVR2_SUBSYS_xxxx macros, with one subsystem per bit position. At any
1070 time the set of configured or active subsystems can be queried just by
1071 looking at that mask. To change bits in that mask, this function here
1072 must be called. The "msk" argument indicates which bit positions to
1073 change, and the "val" argument defines the new values for the positions
1074 defined by "msk".
1075
1076 There is a priority ordering of starting / stopping things, and for
1077 multiple requested changes, this function implements that ordering.
1078 (Thus we will act on a request to load encoder firmware before we
1079 configure the encoder.) In addition to priority ordering, there is a
1080 recovery strategy implemented here. If a particular step fails and we
1081 detect that failure, this function will clear the affected subsystem bits
1082 and restart. Thus we have a means for recovering from a dead encoder:
1083 Clear all bits that correspond to subsystems that we need to restart /
1084 reconfigure and start over.

271 This next batch of horrible preprocessor hackery is needed because the
272 kernel's class_device_attribute mechanism fails to pass the actual
273 attribute through to the show / store functions, which means we have no
274 way to package up any attribute-specific parameters, like for example the
275 control id. So we work around this brain-damage by encoding the control
276 id into the show / store functions themselves and pick the function based
277 on the control id we're setting up. These macros try to ease the pain.
278 Yuck.

736 atomic read of the device mapping array here, we still need the
737 mutex. The problem is that there is a tiny race possible when
738 we register the device. We can't update the device mapping
739 array until after the device has been registered, owing to the
740 fact that we can't know the minor device number until after the
741 registration succeeds. And if another thread tries to open the
742 device in the window of time after registration but before the
743 map is updated, then it will get back an erroneous null pointer
744 and the open will result in a spurious failure. The only way to
745 prevent that is to (a) be inside the mutex here before we access
746 the array, and (b) cover the entire registration process later
747 on with this same mutex. Thus if we get inside the mutex here,
748 then we can be assured that the registration process actually
749 completed correctly. This is an unhappy complication from the
750 use of global data in a driver that lives in a preemptible
751 environment. It sure would be nice if the video device itself
752 had a means for storing and retrieving a local context pointer.
