* [media] gsc-m2m: Use an unsigned data type for a variableMarkus Elfring2016-01-251-1/+1
| | | | | | | | | | | | | The data type "int" was used by the variable "ret" in the gsc_m2m_poll() function despite of the aspect that the type "unsigned int" will usually be needed for the return value from a call of the v4l2_m2m_poll() function. Improve this implementation detail by addition of the type modifier then. This issue was detected by using the Coccinelle software.

* [media] vb2: drop v4l2_format argument from queue_setupHans Verkuil2015-12-181-1/+0Star
| | | | | | | | | | | | | | | | | | | | | The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* [media] vb2: stop_streaming should return voidHans Verkuil2014-04-231-3/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | The vb2 core ignores any return code from the stop_streaming op. And there really isn't anything it can do anyway in case of an error. So change the return type to void and update any drivers that implement it. The int return gave drivers the idea that this operation could actually fail, but that's really not the case. The pwc amd sdr-msi3101 drivers both had this construction: if (mutex_lock_interruptible(&s->v4l2_lock)) return -ERESTARTSYS; This has been updated to just call mutex_lock(). The stop_streaming op expects this to really stop streaming and I very much doubt this will work reliably if stop_streaming just returns without really stopping the DMA.

| | | | | | | | | | | | | | | | | | | | | | | When the current context is running, 1] If release() or streamoff() is called on the current context, it waits until the job is aborted or finished. 2] If the job is finished, driver will call the v4l2_m2m_job_finish(). 3] If the job is aborted inside device_run callback, then driver has to inform the v4l2 mem2mem framework about the same by calling v4l2_m2m_job_finish() with VB2_BUF_STATE_ERROR. The current code doesn't call v4l2_m2m_job_finish() in the case, where the job is aborted from the device_run callback. This scenerio is producing a hang as the other queued contexts are not getting scheduled. By adding the ABORT state, driver can understand the current job is aborted and not finished. By checking this flag, driver can call v4l2_m2m_job_finish() with VB2_BUF_STATE_ERROR.
