* [media] v4l2-dev: add flag to have the core lock all file operationsHans Verkuil2012-05-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This used to be the default if the lock pointer was set, but now that lock is by default only used for ioctl serialization. Those drivers that already used core locking have this flag set explicitly, except for some drivers where it was obvious that there was no need to serialize any file operations other than ioctl. The drivers that didn't need this flag were: drivers/media/radio/dsbr100.c drivers/media/radio/radio-isa.c drivers/media/radio/radio-keene.c drivers/media/radio/radio-miropcm20.c drivers/media/radio/radio-mr800.c drivers/media/radio/radio-tea5764.c drivers/media/radio/radio-timb.c drivers/media/video/vivi.c sound/i2c/other/tea575x-tuner.c The other drivers that use core locking and where it was not immediately obvious that this flag wasn't needed were changed so that the flag is set together with a comment that that driver needs work to avoid having to set that flag. This will often involve taking the core lock in the fops themselves. Eventually this flag should go and it should not be used in new drivers. There are a few reasons why we want to avoid core locking of non-ioctl fops: in the case of mmap this can lead to a deadlock in rare situations since when mmap is called the mmap_sem is held and it is possible for other parts of the code to take that lock as well (copy_from_user()/copy_to_user() perform a down_read(&mm->mmap_sem) when a page fault occurs). It is very unlikely that that happens since the core lock serializes all fops, but the kernel warns about it if lock validation is turned on. For poll it is also undesirable to take the core lock as that can introduce increased latency. The same is true for read/write. While it was possible to make flags or something to turn on/off taking the core lock for each file operation, in practice it is much simpler to just not take it at all except for ioctl and leave it to the driver to take the lock. There are only a handful fops compared to the zillion ioctls we have. I also wanted to make it obvious which drivers still take the lock for all fops, so that's why I chose to have drivers set it explicitly.

For whatever unknown reason, xine (and xine-lib clients) wants that the frontend to tell what frequency he is using even before the PLL lock (or at least, it expects a non-zero frequency). On DVB, the frequency is only actually known after a frequency zig-zag seek, done by the DVB core. Anyway, the fix was trivial. That solves Fedora BZ#808871. - ivtv: fix a regression when selecting the language channel - uvc: fix a race-related crash - it913x: fixes firmware loading - two trivial patches (a dependency issue at a radio driver at sound Kconfig, and a warning fix on dvb). * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: [media] uvcvideo: Fix race-related crash in uvc_video_clock_update() [media] Drivers/media/radio: Fix build error [media] dvb_frontend: fix compiler warning [media] it913x: fix firmware loading errors [media] ivtv: Fix AUDIO_(BILINGUAL_)CHANNEL_SELECT regression [media] dvb_frontend: regression fix: userspace ABI broken for xine

I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of the removal of get_driver()/put_driver(), this patch (as1510) changes driver_find(); it now drops the reference it acquires before returning. The patch also adjusts all the callers of driver_find() to remove the now unnecessary calls to put_driver(). In addition, the patch adds a warning to driver_find(): Callers must make sure the driver they are searching for does not get unloaded while they are using it. This has always been the case; driver_find() has never prevented a driver from being unregistered or unloaded. Hence the patch will not introduce any new bugs. The existing callers all seem to be okay in this respect, however I don't understand the video drivers well enough to be certain about them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For drivers that properly use the v4l2 framework (i.e. set v4l2_dev in the video_device struct), the start and end messages of VIDIOC_LOG_STATUS are now generated automatically. People tended to forget these, but the v4l2-ctl tool scans for these messages, and it also makes it easier to read the status output in the kernel log. The cx18, ivtv and bttv drivers were changed since they no longer need to log these start/end messages. In saa7164 two empty log_status functions were removed. Also added a helper function to v4l2-ctrl.c that can be used as the vidioc_log_status callback if all you need to do is to log the current control values. This is now used by pwc and vivi.

* [media] v4l2-event/ctrls/fh: allocate events per fh and per type instead of ↵Hans Verkuil2011-07-272-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | just per-fh The driver had to decide how many events to allocate when the v4l2_fh struct was created. It was possible to add more events afterwards, but there was no way to ensure that you wouldn't miss important events if the event queue would fill up for that filehandle. In addition, once there were no more free events, any new events were simply dropped on the floor. For the control event in particular this made life very difficult since control status/value changes could just be missed if the number of allocated events and the speed at which the application read events was too low to keep up with the number of generated events. The application would have no idea what the latest state was for a control since it could have missed the latest control change. So this patch makes some major changes in how events are allocated. Instead of allocating events per-filehandle they are now allocated when subscribing an event. So for that particular event type N events (determined by the driver) are allocated. Those events are reserved for that particular event type. This ensures that you will not miss events for a particular type altogether. In addition, if there are N events in use and a new event is raised, then the oldest event is dropped and the new one is added. So the latest event is always available. This can be further improved by adding the ability to merge the state of two events together, ensuring that no data is lost at all. This will be added in the next patch. This also makes it possible to allow the user to determine the number of events that will be allocated. This is not implemented at the moment, but would be trivial.

| | | | | | | | | | | | | Drivers that supported events used to be rare, but now that controls can also raise events this will become much more common since almost all drivers have controls. This means that keeping struct v4l2_events as a separate struct make no more sense. Merging it into struct v4l2_fh simplifies things substantially as it is now an integral part of the filehandle struct.
