* [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] media, cx231xx: Fix double free on closeJesper Juhl2012-03-191-4/+2
| | | | | | | | | | | | | | | | | | | In cx231xx_v4l2_close() there are two calls to cx231xx_release_resources(dev) followed by kfree(dev). That is a problem since cx231xx_release_resources() already kfree()'s its argument, so we end up doing a double free. Easily resolved by just removing the redundant kfree() calls after the calls to cx231xx_release_resources(). I also changed the 'dev = NULL' assignments (which are rather pointless since 'dev' is about to go out of scope), to 'fh->dev = NULL' since it looks to me that that is what was actually intended. And I removed the 'dev = NULL' assignment at the end of cx231xx_release_resources() since it is pointless.

* [media] cx231xx: fix device disconnect checksMauro Carvalho Chehab2012-01-101-10/+4
| | | | | | | | | | | | | | | | The driver were using DEV_MISCONFIGURED on some places, and DEV_DISCONNECTED on others. In a matter of fact, DEV_MISCONFIGURED were set only during the usb disconnect callback, with was confusing. Also, the alsa driver never checks if the device is present, before doing some dangerous things. Remove DEV_MISCONFIGURED, replacing it by DEV_DISCONNECTED. Also, fixes the other usecases for DEV_DISCONNECTED. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] Stop using linux/version.h on most video driversMauro Carvalho Chehab2011-07-271-10/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the modified drivers didn't have any version increment since Jan, 1 2011. Several of them didn't have any version increment for a long time, even having new features and important bug fixes happening. As we're now filling the QUERYCAP version with the current Kernel Release, we don't need to maintain a per-driver version control anymore. So, let's just use the default. In order to preserve the Kernel module version history, a KERNEL_VERSION() macro were added to all modified drivers, and the extraver number were incremented. I opted to preserve the per-driver version control to a few pwc, pvrusb2, s2255, s5p-fimc and sh_vou. A few drivers are still using the legacy way to handle ioctl's. So, we can't do such change on them, otherwise, they'll break. Those are: uvc, et61x251 and sn9c102. The rationale is that the per-driver version control seems to be actively maintained on those. Yet, I think that the better for them would be to just use the default version numbering, instead of doing that by themselves.

| | | | | | | | | | | | | | | | | Move the responsibility for setting up the horizontal and vertical scalers entirely to the cx25840 driver. The cx231xx-avcore was actually programming garbage into the HSCALE_CTRL and VSCALE_CTRL registers (because of differences in how the em28xx driver worked, which the cx231xx driver was derived from). The net effect is that the scaler now works properly (tested with both PAL and NTSC under mplayer and tvtime). This patch also gets rid of cx25840 errors showing up in dmesg which say "720x480 is not a valid size" (since we now properly setup the size of the active video area).

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | Instead of using the minor number in kernel log messages, use the device node name as returned by the video_device_node_name() function. This makes debug, informational and error messages easier to understand for end users.

* V4L/DVB (13238): v4l2_subdev: rename tuner s_standby operation to core s_powerLaurent Pinchart2009-12-051-1/+1
| | | | | | | | | | | | | | | | | Upcoming I2C v4l2_subdev drivers need a way to control the subdevice power state from the core. This use case is already partially covered by the tuner s_standby operation, but no way to explicitly come back from the standby state is available. Rename the tuner s_standby operation to core s_power, and fix tuner drivers accordingly. The tuner core will call s_power(0) instead of s_standby(). No explicit call to s_power(1) is required for tuners as they are supposed to wake up from standby automatically.

* V4L/DVB (11913): cx231xx: TRY_FMT should not actually set anythingTrent Piepho2009-06-231-7/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the TRY_FMT handler the function get_scale() is called to find what the scaler hardware will produce for a requested size. The problem is that get_scale(struct cx231xx *dev, ..., unsigned int *vscale, unsigned int *hscale) saves the calculated scale values into both the pointer arguments and into dev's hscale and vscale fields. TRY_FMT shouldn't actually change anything in the device state. The code to in get_scale() that writes to dev->[hv]scale can just be deleted. In all cases when dev's fields should be modified, get_scale() was called with get_scale(dev, ..., &dev->hscale, &dev->vscale), so dev was getting updated anyway. This didn't actually cause a problem because nothing ever actually made use of the hscale and vscale fields. I changed cx231xx_resolution_set() to use those fields rather than re-calculate them with a call to get_scale(). Updating [hv]scale in cx231xx_resolution_set() isn't necessary because every call of cx231xx_resolution_set() was already preceded by a call to get_scale() or setting the [hv]scale fields, so they will be always be up-to-date w.r.t. width and height. Removing the call to get_scale() from cx231xx_resolution_set() allowed making get_scale() a static function, which is a good thing for something with such a short name. There is already another function with the same name in the em28xx driver, but that one is static.
