| | | | | | | | | | | | | There will be no soc_camera_device instance with a soc-camera device is used with a non soc-camera host, so we won't be able to pass the soc_camera_device fake platform device to board code. Pass the physical device instead. The argument is currently not used by any board file so this is safe.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | user-space If multiple clients are registered on a single camera host interface, the user-space hot-plug software can try to access the one, that probed first, before probing of the second one has completed. This can be handled by individual host drivers, but it is even better to hold back the user-space until all the probing on this host has completed. This fixes a race on ecovec with two clients registered on the CEU1 host, which otherwise triggers a BUG() in sh_mobile_ceu_remove_device().

* | [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.

* [media] soc-camera: change order of removing deviceLei Wen2012-01-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | As our general practice, we use stream off before we close the video node. So that the drivers its stream off function would be called before its remove function. But for the case for ctrl+c, the program would be force closed. We have no chance to call that vb2 stream off from user space, but directly call the remove function in soc_camera. In that common code of soc_camera: ici->ops->remove(icd); if (ici->ops->init_videobuf2) vb2_queue_release(&icd->vb2_vidq); It would first call the device remove function, then release vb2, in which stream off function is called. Thus it create different order for the driver. This patch change the order to make driver see the same sequence to make it happy.

* [media] V4L: soc-camera: make (almost) all client drivers re-usable outside ↵Guennadi Liakhovetski2011-11-031-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | of the framework The most important change in this patch is direct linking to struct soc_camera_link via the client->dev.platform_data pointer. This makes most of the soc-camera client drivers also usable outside of the soc-camera framework. After this change all what is needed for these drivers to function are inclusions of soc-camera headers for some convenience macros, suitably configured platform data, which is anyway always required, and loaded soc-camera core module for library functions. If desired, these library functions can be made generic in the future and moved to a more neutral location. The only two client drivers, that still depend on soc-camera are: mt9t031: it uses struct video_device for its PM. Since no hardware is available, alternative methods cannot be tested. ov6650: it uses struct soc_camera_device to pass its sense data back to the bridge driver. A generic v4l2-subdevice approach should be developed to perform this. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB: soc-camera: allow only one video queue per deviceGuennadi Liakhovetski2010-10-211-90/+88
| | | | | | | | | Multiple user-space application instances can open the same video device, but it only makes sense for one of them to manage the videobuffer queue and set video format of the device. Restrict soc-camera respectively. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB: v4l2-subdev.h: fix enum_mbus_fmt prototypeHans Verkuil2010-06-011-1/+2
| | | | | | | | | | | enum_mbus_fmt received an index argument that was defined as an int instead of an unsigned int. This is now fixed. This had the knock-on effect that the index argument in the callback get_formats in soc_camera.h also had to be changed to unsigned int.
