* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-304-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* V4L/DVB (13170): bttv: Fix reversed polarity error when switching video standardMike Isely2009-11-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bttv driver function which handles switching of the video standard (set_tvnorm() in bttv-driver.c) includes a check which can optionally also reset the cropping configuration to a default value. It is "optional" based on a comparison of the cropcap parameters of the previous vs the newly requested video standard. The comparison is being done with a memcmp(), a function which only returns a true value if the comparison actually fails. This if-statement appears to have been written to assume wrong memcmp() semantics. That is, it was re-initializing the cropping configuration only if the new video standard did NOT have different cropcap values. That doesn't make any sense. One definitely should reset things if the cropcap parameters are different - if there's any comparison to made at all. The effect of this problem was that a transition from, say, PAL to NTSC would leave in place old cropping setup that made sense for the PAL geometry but not for NTSC. If the application doesn't care about cropping it also won't try to reset the cropping configuration, resulting in an improperly cropped video frame. In the case I was testing this actually caused black video frames to be displayed. Another interesting effect of this bug is that if one does something which does NOT change the video standard and this function is run, then the cropping setup gets reset anyway - again because of the backwards comparison. It turns out that just running anything which merely opens and closes the video device node (e.g. v4l-info) will cause this to happen. One can argue that simply opening the device node and not doing anything to it should not mess with any of its state - but because of this behavior, any TV app which does such things (e.g. xawtv) probably therefore doesn't see the problem. The solution is to fix the sense of the if-statement. It's easy to see how this mistake could have been made given how memcmp() works. The patch is therefore removal of a single "!" character from the if-statement in set_tvnorm in bttv-driver.c.

* V4L/DVB (13169): bttv: Fix potential out-of-order field processingMike Isely2009-11-071-4/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a subtle interaction in the bttv driver which can result in fields being repeatedly processed out of order. This is a problem specifically when running in V4L2_FIELD_ALTERNATE mode (probably the most common case). 1. The determination of which fields are associated with which buffers happens in videobuf, before the bttv driver gets a chance to queue the corresponding DMA. Thus by the point when the DMA is queued for a given buffer, the algorithm has to do the queuing based on the buffer's already assigned field type - not based on which field is "next" in the video stream. 2. The driver normally tries to queue both the top and bottom fields at the same time (see bttv_irq_next_video()). It tries to sort out top vs bottom by looking at the field type for the next 2 available buffers and assigning them appropriately. 3. However the bttv driver *always* actually processes the top field first. There's even an interrupt set aside for specifically recognizing when the top field has been processed so that it can be marked done even while the bottom field is still being DMAed. Given all of the above, if one gets into a situation where bttv_irq_next_video() gets entered when the first available buffer has been pre-associated as a bottom field, then the function is going to process the buffers out of order. That first available buffer will be put into the bottom field slot and the buffer after that will be put into the top field slot. Problem is, since the top field is always processed first by the driver, then that second buffer (the one after the first available buffer) will be the first one to be finished. Because of the strict fifo handling of all video buffers, then that top field won't be seen by the app until after the bottom field is also processed. Worse still, the app will get back the chronologically later bottom field first, *before* the top field is received. The buffer's timestamps will even be backwards. While not fatal to most TV apps, this behavior can subtlely degrade userspace deinterlacing (probably will cause jitter). That's probably why it has gone unnoticed. But it will also cause serious problems if the app in question discards all but the latest received buffer (a latency minimizing tactic) - causing one field to only ever be displayed since the other is now always late. Unfortunately once you get into this state, you're stuck this way - because having consumed two buffers, now the next time around the "first" available buffer will again be a bottom field and the same thing happens. How can we get into this state? In a perfect world, where there's always a few free buffers queued to the driver, it should be impossible. However if something disrupts streaming, e.g. if the userspace app can't queue free buffers fast enough for a moment due perhaps to a CPU scheduling glitch, then the driver can get momentarily starved and some number of fields will be dropped. That's OK. But if an odd number of fields get dropped, then that "first" available buffer might be the bottom field and now we're stuck... This patch fixes that problem by deliberately only setting up a single field for one frame if we don't get a top field as the first available buffer. By purposely skipping the other field, then we only handle a single buffer thus bringing things back into proper sync (i.e. top field first) for the next frame. To do this we just drop the few lines in bttv_irq_next_video() that attempt to set up the second buffer when that second buffer isn't for the bottom field. This is definitely a problem in when in V4L2_FIELD_ALTERNATE mode. In the other modes this change either has no effect or doesn't harm things any further anyway.

* V4L/DVB (12595): common/ir: use a struct for keycode tablesMauro Carvalho Chehab2009-09-121-13/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, V4L uses a scancode table whose index is the scancode and the value is the keycode. While this works, it has some drawbacks: 1) It requires that the scancode to be at the range 00-7f; 2) keycodes should be masked on 7 bits in order for it to work; 3) due to the 7 bits approach, sometimes it is not possible to replace the default keyboard to another one with a different encoding rule; 4) it is different than what is done with dvb-usb approach; 5) it requires a typedef for it to work. This is not a recommended Linux CodingStyle. This patch is part of a larger series of IR changes. It basically replaces the IR_KEYTAB_TYPE tables by a structured table: struct ir_scancode { u16 scancode; u32 keycode; }; This is very close to what dvb does. So, a further integration with DVB code will be easy. While we've changed the tables, for now, the IR keycode handling is still based on the old approach. The only notable effect is the redution of about 35% of the ir-common module size: text data bss dec hex filename 6721 29208 4 35933 8c5d old/ir-common.ko 5756 18040 4 23800 5cf8 new/ir-common.ko In thesis, we could be using above u8 for scancode, reducing even more the size of the module, but defining it as u16 is more convenient, since, on dvb, each scancode has up to 16 bits, and we currently have a few troubles with rc5, as their scancodes are defined with more than 8 bits. This patch itself shouldn't be doing any functional changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB (11844): ir-kbd-i2c: Switch to the new-style device binding modelJean Delvare2009-06-161-0/+21
| | | | | | | | | | | | | | | | | | | Let card drivers probe for IR receiver devices and instantiate them if found. Ultimately it would be better if we could stop probing completely, but I suspect this won't be possible for all card types. There's certainly room for cleanups. For example, some drivers are sharing I2C adapter IDs, so they also had to share the list of I2C addresses being probed for an IR receiver. Now that each driver explicitly says which addresses should be probed, maybe some addresses can be dropped from some drivers. Also, the special cases in saa7134-i2c should probably be handled on a per-board basis. This would be more efficient and less risky than always probing extra addresses on all boards. I'll give it a try later. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | disappear. Since i2c autoprobing will disappear bttv needs to be converted to use v4l2_subdev instead. Without autoprobing the autoload module option has become obsolete. A warning is generated if it is set, but it is otherwise ignored. Since the bttv card definitions are of questionable value a new option was introduced to allow the user to control which audio module is selected: msp3400, tda7432 or tvaudio (or none at all). By default bttv will use the card definitions and fallback on tvaudio as the last resort. If no audio device was found a warning is printed. The saa6588 RDS device is now also explicitly probed since it is no longer possible to autoprobe it. A new saa6588 module option was added to override the card definition since I suspect more cards have this device than one would guess from the card definitions. Note that the probe addresses of the i2c modules are hardcoded in this driver. Once all v4l drivers are converted to v4l2_subdev this will be cleaned up. Such data belongs in an i2c driver header.

* V4L/DVB (11262): bttv: Remove buffer type check from vidioc_g_parmTrent Piepho2009-03-301-2/+0
| | | | | | | | | | | | | | | | The v4l2-ioctl core only allows buffer types for which the corresponding ->vidioc_try_fmt_xxx() methods are defined to be used with vidioc_(q|dq|query)bufs(), vidioc_reqbufs() and now vidioc_(s|g)_parm. The driver was only allowing VIDEO_CAPTURE buffers for g_parm, but since the driver defines ->vidioc_try_fmt_vid_overlay() and ->vidioc_try_fmt_vbi_cap() it will now allow VIDEO_OVERLAY and VBI_CAPTURE buffers as well. This should be fine as the driver only fills in the frame rate field, which is just as valid for video overlay and vbi capture as it is for video capture.

It has 16 video inputs and 4 audio inputs, and it is almost identical to the GV-800, as seen on http://bttv-gallery.de . The only difference appears to be the analog mux, it has a CD22M3494 in place of the MT8816AP. The card has a blue PCB, as seen in this picture: http://www.gsbr.com.br/imagem/kits/GeoVision%20GV%20800.jpg . This card wasn't originally supported, and it was detected as UNKNOWN/GENERIC. The video inputs weren't working, so I tried "forcing" a few cards like the GeoVision GV-600, but there was still no video. So I made a patch to support this card, based on the Kodicom 4400r.

If not, only a few changes should be required on the gv800s_write() function. After this patch, the video inputs work correctly on linux 2.6.24 and 2.6.27 using the software 'motion'. The input order may seem a little odd, but it's the order the original software/driver uses, and I decided to keep that order to get the most out of the card. I tried to get the audio working with the snd-bt87x module, but I only get noise from every audio input, even after selecting a different mux with alsamixer. Also, after trying to play sound from those sources, I randomly get a RISC error about an invalid RISC opcode, and then that output stops working. I also can't change the sampling rate when recording. Any pointers to adding audio support are welcome.
