* [media] v4l: Remove hardcoded module names passed to v4l2_i2c_new_subdev*Laurent Pinchart2010-10-22
| | | | | | | | | | | | | With the v4l2_i2c_new_subdev* functions now supporting loading modules based on modaliases, replace the hardcoded module name passed to those functions by NULL. All corresponding I2C modules have been checked, and all of them include a module aliases table with names corresponding to what the drivers modified here use.

* V4L/DVB: videobuf: add queue argument to videobuf_waiton()Hans Verkuil2010-10-20
| | | | | | | | | | | | | | | | videobuf_waiton() must unlock and relock ext_lock if it has to wait. For that to happen it needs the videobuf_queue pointer. Don't attempt to unlock/relock q->ext_lock unless it was locked in the first place. vb->state has to be protected by a spinlock to be safe.

* Revert "V4L/DVB (11906): saa7134: Use v4l bounding/alignment function"Herton Ronaldo Krzesinski2010-05-19
| | | | | | | | | | | | | | | | | | | This reverts commit bc52d6eb44de8f19934768d4d10d19fdbdc99950. On newer kernels, a saa7134 board stopped to display TV video output properly. After a bisect, I found it as the commit causing the issue. Turns out that v4l_bound_align_image isn't doing the same bounding calculation as manually done previously in saa7134_try_fmt_vid_cap. What isn't equal is the calculation done in clamp align, while previously it did "f->fmt.pix.width &= ~0x03", clamp_align function does "Round to nearest aligned value" as stated in the comment, which yields a different result. If I comment the round calculation in clamp_align like this: "x = (x /*+ (1 << (align - 1))*/) & mask", I get it fixed too, because this way the calculation is the same then.

* V4L/DVB: Teach drivers/media/IR/ir-raw-event.c to use durationsDavid Härdeman2010-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | drivers/media/IR/ir-raw-event.c is currently written with the assumption that all "raw" hardware will generate events only on state change (i.e. when a pulse or space starts). However, some hardware (like mceusb, probably the most popular IR receiver out there) only generates duration data (and that data is buffered so using any kind of timing on the data is futile). Furthermore, using signed int's to represent pulse/space durations is a well-known approach when writing ir decoders. With this patch: - s64 int's are used to represent pulse/space durations in ns - a workqueue is used to decode the ir protocols outside of interrupt context - #defines are added to make decoders clearer - decoder reset is implemented by passing a zero duration to the kfifo queue and decoders are updated accordingly Signed-off-by: David Härdeman <david@hardeman.nu> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB: ir-core: Distinguish sysfs attributes for in-hardware and raw decodersMauro Carvalho Chehab2010-05-19
| | | | | | | | | | | | | | Some devices have in-hardware Remote Controller decoder, while others need a software decoder to get the IR code. As each software decoder can be enabled/disabled individually, allowing multiple protocol decoding capability. On the other hand, hardware decoders have a limited protocol support, often being able of decoding just one protocol each time. So, each type needs a different set of capabilities to control the supported protocol(s). Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB: ir-nec-decoder: Reimplement the entire decoderMauro Carvalho Chehab2010-05-19
| | | | | | | | | | | | | | | | | | | | | | | Thanks to Andy Walls <awalls@md.metrocast.net> for pointing me his code, that gave me some ideas to better implement it. After some work with saa7134 bits, I found a way to catch both IRQ edge pulses. By enabling it, the NEC decoder can now take both pulse and spaces into account, making it more precise. Instead of the old strategy of handling the events all at once, this code implements a state machine. Due to that, it handles individual pulse or space events, validating them against the protocol, producing a much more reliable decoding. With the new implementation, the protocol trailer bits are properly handled, making possible for the repeat key to work. Also, the code is now capable of handling both NEC and NEC extended IR devices. With NEC, it produces a 16 bits code, while with NEC extended, a 24 bits code is returned.

* V4L/DVB: saa7134: Add support for both positive and negative edge IRQMauro Carvalho Chehab2010-05-19
| | | | | | | | | | | | | | | | | | | | The code that enables IRQ for the Remote Controller on saa7134 is a little messy: it is outside saa7134-input, it checks if RC is GPIO based, and it mixes both serial raw decode with parallel reads from a hardware-based IR decoder. Also, currently, it doesn't allow to trigger both transition edges at GPIO16 and GPIO18 lines. A rework on the code is needed to provide a better way to specify what saa7134-input needs, maybe even moving part of the code from saa7134-core and saa7134-cards into saa7134-input. Yet, as a large rework is happening at RC core, it is better to wait until the core changes stablize, in order to rework saa7134 RC internals.While this don't happen, let's just change the logic a little bit to allow enabling IRQ to be generated on both edge transitions, in order to better support pulse/space raw decoders.

* V4L/DVB: saa7134: Fix IRQ2 bit names for the register mapMauro Carvalho Chehab2010-05-19
| | | | | | | | | | | | | | There's an error at the IRQ2 bit map registers. Also, it doesn't show what bits are needed for positive and for negative edge. In the case of IR raw decoding, for some protocols, it is important to detect both positive and negative edges. So, a latter patch will need to use the other values. Also, the code that detects problems on IRQ handling is incomplete, as it disables only one of the IRQ bits for GPIO16 and GPIO18. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB: saa7134: don't wait too much to generate an IR event on raw_decodeMauro Carvalho Chehab2010-05-17
| | | | | | | | | | | | | | | | | At raw_decode mode, the key is processed after the end of a timer. The previous code resets the timer every time something is received at the IR port. While this works fine with IR's that don't implement repeat, like Avermedia RM-JX IR, it keeps waiting until keydown, on IR's that implement NEC repeat command, like the Terratec yellow. The solution is to change the behaviour to do the timeout after the first received data. The timeout is currently set to 15 ms, as it works fine with NEC protcocol. It may need some adjustments to support other protocols and to better handle spurious detections that may happen with some IR sensors. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB: drivers/media/video: move dereference after NULL testJulia Lawall2010-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In quickcam_messenger.c, if the NULL test on uvd is needed, then the dereference should be after the NULL test. In vpif_display.c, std_info is initialized to the address of a structure field. This seems unlikely to be NULL. Test std_info->stdid instead. In saa7134-alsa.c, the function is only called from one place, where the chip argument has already been dereferenced.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
