[media] v4l2-dev: add flag to have the core lock all file operations

2012-05-14T12:19:38+00:00

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] usbvision: Drop broken 10-bit I2C address support

2011-11-08T13:38:10+00:00

The support for 10-bit I2C addresses in usbvision seems plain broken to me. I had already noticed that back in February 2007 [1]. The code was not fixed since then, so I take it that it's not actually needed. And as a matter of fact I don't know of any 10-bit addressed I2C tuner, encode, decoder or the like. So let's simply get rid of the broken and useless code. I'm also adding I2C_FUNC_I2C, as the driver and hardware support plain I2C messaging.

drivers/media: Add module.h to all files using it implicitly

[media] drivers/media: do not use EXTRA_CFLAGS

2011-09-03T21:50:59+00:00

Usage of these flags has been deprecated for nearly 4 years by: commit f77bf01425b11947eeb3b5b54685212c302741b8 Author: Sam Ravnborg Date: Mon Oct 15 22:25:06 2007 +0200 kbuild: introduce ccflags-y, asflags-y and ldflags-y Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command line use. By default, gmake(1) do not override command line setting, so this is likely to result in build failure or unexpected behavior. Replace their usage by Kbuild's `{as,cc,ld}flags-y'.
