* [media] vb2: add allow_zero_bytesused flag to the vb2_queue structKamil Debski2015-04-101-6/+33
| | | | | | | | | | | | | | | | | The vb2: fix bytesused == 0 handling (8a75ffb) patch changed the behavior of __fill_vb2_buffer function, so that if bytesused is 0 it is set to the size of the buffer. However, bytesused set to 0 is used by older codec drivers as as indication used to mark the end of stream. To keep backward compatibility, this patch adds a flag passed to the vb2_queue_init function - allow_zero_bytesused. If the flag is set upon initialization of the queue, the videobuf2 keeps the value of bytesused intact in the OUTPUT queue and passes it to the driver.

| | | | | | | | | | Changeset 9b174527e7b7 added this new macro, ensuring that it is true only if the function is actually reachable. However, newer drivers were added since when it was written. So, change those drivers to also use it. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] Add and use IS_REACHABLE macroArnd Bergmann2015-04-08115-116/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the media drivers, the v4l2 core knows about all submodules and calls into them from a common function. However this cannot work if the modules that get called are loadable and the core is built-in. In that case we get drivers/built-in.o: In function `set_type': drivers/media/v4l2-core/tuner-core.c:301: undefined reference to `tea5767_attach' drivers/media/v4l2-core/tuner-core.c:307: undefined reference to `tea5761_attach' drivers/media/v4l2-core/tuner-core.c:349: undefined reference to `tda9887_attach' drivers/media/v4l2-core/tuner-core.c:405: undefined reference to `xc4000_attach' This was working previously, until the IS_ENABLED() macro was used to replace the construct like #if defined(CONFIG_DVB_CX24110) || (defined(CONFIG_DVB_CX24110_MODULE) && defined(MODULE)) with the difference that the new code no longer checks whether it is being built as a loadable module itself. To fix this, this new patch adds an 'IS_REACHABLE' macro, which evaluates true in exactly the condition that was used previously. The downside of this is that this trades an obvious link error for a more subtle runtime failure, but it is clear that the change that introduced the link error was unintentional and it seems better to revert it for now. Also, a similar change was originally created by Trent Piepho and then reverted by teh change to the IS_ENABLED macro. Ideally Kconfig would be used to avoid the case of a broken dependency, or the code restructured in a way to turn around the dependency, but either way would require much larger changes here.

* [media] xc5000: fix memory corruption when unplugging deviceDevin Heitmueller2015-04-081-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | This patch addresses a regression introduced in the following patch: commit 5264a522a597032c009f9143686ebf0fa4e244fb Author: Shuah Khan <shuahkh@osg.samsung.com> [media] media: tuner xc5000 - release firmwware from xc5000_release() The "priv" struct is actually reference counted, so the xc5000_release() function gets called multiple times for hybrid devices. Because release_firmware() was always being called, it would work fine as expected on the first call but then the second call would corrupt aribtrary memory. Set the pointer to NULL after releasing so that we don't call release_firmware() twice. This problem was detected in the HVR-950q where plugging/unplugging the device multiple times would intermittently show panics in completely unrelated areas of the kernel.

* [media] vivid: add CVT,GTF standards to vivid dv timings capsPrashant Laddha2015-04-081-2/+3
| | | | | | | | | | | | | | | | | Currently vivid supports V4L2_DV_BT_STD_DMT and V4L2_DV_BT_STD_CEA861 discrete video standards. Extending the capability set to allow for setting CVT and GTF standards. This change, along with adding the support for calculating CVT, GTF timings in v4l2-ctl would extend the number of resolutions supported by vivid to almost any custom resolution. Also extending the limits on min and max pixel clock to accommodate pixel clock range provided by cvt/gtf for resolutions ranging from 640x360p50 to 4kx2Kp60.

* [media] sur40: fix occasional hard freeze due to buffer queue underrunFlorian Echtler2015-04-081-0/+5
| | | | | | | | | | | | | | | | This patch fixes a kernel panic which occurs when buf_list is empty. This can happen occasionally when user space is under heavy load (e.g. due to image processing on the CPU) and new buffers aren't re-queued fast enough. In that case, vb2_start_streaming_called can return true, but when the spinlock is taken and sur40_poll attempts to fetch the next buffer from buf_list, the list is in fact empty. This patch needs to be applied on top of the queued one adding V4L2 support to the sur40 driver.
