10 ---help---
11 This is a video4linux driver for Conexant 23416 based
12 usb2 personal video recorder devices.
13
14 To compile this driver as a module, choose M here: the
15 module will be called pvrusb2
16
17config VIDEO_PVRUSB2_24XXX
18 bool "Hauppauge WinTV-PVR USB2 support for 24xxx model series"
19 depends on VIDEO_PVRUSB2 && EXPERIMENTAL
20 select VIDEO_CX25840
21 select VIDEO_WM8775
22 ---help---
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.
36
37config VIDEO_PVRUSB2_SYSFS
38 bool "pvrusb2 sysfs support (EXPERIMENTAL)"
39 default y
40 depends on VIDEO_PVRUSB2 && SYSFS && EXPERIMENTAL
41 ---help---
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.
52
53config VIDEO_PVRUSB2_DEBUGIFC
54 bool "pvrusb2 debug interface"
55 depends on VIDEO_PVRUSB2_SYSFS
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.

142 The encoder seems to speak entirely using blocks 32 bit words.
143 In ivtv driver terms, this is a mailbox which we populate with
144 data and watch what the hardware does with it. The first word
145 is a set of flags used to control the transaction, the second
146 word is the command to execute, the third byte is zero (ivtv
147 driver suggests that this is some kind of return value), and
148 the fourth byte is a specified timeout (windows driver always
149 uses 0x00060000 except for one case when it is zero). All
150 successive words are the argument words for the command.
151
152 First, write out the entire set of words, with the first word
153 being zero.
154
155 Next, write out just the first word again, but set it to
156 IVTV_MBOX_DRIVER_DONE | IVTV_DRIVER_BUSY this time (which
157 probably means "go").
158
159 Next, read back 16 words as status. Check the first word,
160 which should have IVTV_MBOX_FIRMWARE_DONE set. If however
161 that bit is not set, then the command isn't done so repeat the
162 read.
163
164 Next, read back 32 words and compare with the original
165 arugments. Hopefully they will match.
166
167 Finally, write out just the first word again, but set it to
168 0x0 this time (which probably means "idle").

26 This header sets up all the internal structures and definitions needed to

28 source files which actually implement part of that whole circus should be

1141 This single function is key to pretty much everything. The pvrusb2
1142 device can logically be viewed as a series of subsystems which can be
1143 stopped / started or unconfigured / configured. To get things streaming,
1144 one must configure everything and start everything, but there may be
1145 various reasons over time to deconfigure something or stop something.
1146 This function handles all of this activity. Everything EVERYWHERE that
1147 must affect a subsystem eventually comes here to do the work.
1148
1149 The current state of all subsystems is represented by a single bit mask,
1150 known as subsys_enabled_mask. The bit positions are defined by the
1151 PVR2_SUBSYS_xxxx macros, with one subsystem per bit position. At any
1152 time the set of configured or active subsystems can be queried just by
1153 looking at that mask. To change bits in that mask, this function here
1154 must be called. The "msk" argument indicates which bit positions to
1155 change, and the "val" argument defines the new values for the positions
1156 defined by "msk".
1157
1158 There is a priority ordering of starting / stopping things, and for
1159 multiple requested changes, this function implements that ordering.
1160 (Thus we will act on a request to load encoder firmware before we
1161 configure the encoder.) In addition to priority ordering, there is a
1162 recovery strategy implemented here. If a particular step fails and we
1163 detect that failure, this function will clear the affected subsystem bits
1164 and restart. Thus we have a means for recovering from a dead encoder:
1165 Clear all bits that correspond to subsystems that we need to restart /
1166 reconfigure and start over.

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

808 we register the device. We can't update the device mapping
809 array until after the device has been registered, owing to the
810 fact that we can't know the minor device number until after the
811 registration succeeds. And if another thread tries to open the
812 device in the window of time after registration but before the
813 map is updated, then it will get back an erroneous null pointer
814 and the open will result in a spurious failure. The only way to
815 prevent that is to (a) be inside the mutex here before we access
816 the array, and (b) cover the entire registration process later
817 on with this same mutex. Thus if we get inside the mutex here,
818 then we can be assured that the registration process actually
819 completed correctly. This is an unhappy complication from the
820 use of global data in a driver that lives in a preemptible
821 environment. It sure would be nice if the video device itself
822 had a means for storing and retrieving a local context pointer.
