2011-03-22[media] v4l2: vb2: simplify __vb2_queue_free functionMarek Szyprowski1-6/+2
__vb2_queue_free function doesn't really return anything useful. This patch removes support for the return value to simplify the code. Signed-off-by: Marek Szyprowski <[email protected]> Signed-off-by: Kyungmin Park <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>

2011-03-22[media] v4l2: vb2: fix queue reallocation and REQBUFS(0) caseMarek Szyprowski1-1/+8
This patch fixes 2 minor bugs in videobuf2 core: 1. Queue should be reallocated if one change the memory access method without changing the number of buffers. 2. In case of REQBUFS(0), the request should not be passed to the driver.

2011-03-22[media] s5p-fimc: Fix G_FMT ioctl handlerSylwester Nawrocki1-4/+23
Use pix_mp member of struct v4l2_format to return a format description rather than pix. Also fill in the plane_fmt array. This is a missing bit of conversion to the multiplanar API.

2011-03-22[media] s5p-fimc: Use dynamic debugSylwester Nawrocki1-5/+1
Use pr_debug instead of printk so it is possible to control debug traces at runtime. E.g. to enable debug trace in file fimc-core.c use command: echo -n 'file fimc-core.c +p' > /sys/kernel/debug/dynamic_debug/control or echo -n 'file fimc-core.c -p' > /sys/kernel/debug/dynamic_debug/control to disable.

2011-03-22[media] s5p-fimc: Prevent hanging on device close and fix the lockingSylwester Nawrocki3-114/+136
Rework the locking in m2m driver to assure proper operation on SMP systems. When job_abort or stop_streaming was called to immediately shutdown a memory-to-memory transaction video buffers scheduled for processing were never returned to vb2 and v4l2_m2m_job_finish was not called which led to hanging. Correct this and also return the unprocessed buffers to vb2 marking them as erroneous, in case the end of frame interrupt do not occur.

2011-03-22[media] s5p-fimc: fix ISR and buffer handling for fimc-captureSungchun Kang2-58/+45
In some cases fimc H/W did not stop although there were no output buffers available. So the capture deactivation interrupt routine is modified and the state of ST_CAPT_RUN is cleared only in the LAST-IRQ call. After LAST-IRQ is generated, H/W pointer will be skipped by 1 frame. (reference by user manual) So, S/W pointer should be increased too.

The three new ioctl VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL, VIDIOC_SUBDEV_G_FRAME_INTERVAL and VIDIOC_SUBDEV_S_FRAME_INTERVAL can be used to enumerate and configure a subdev's frame rate from userspace. Two new video::g/s_frame_interval subdev operations are introduced to support those ioctls. The existing video::g/s_parm operations are deprecated and shouldn't be used anymore.

2011-03-22[media] v4l: v4l2_subdev userspace format APILaurent Pinchart13-1/+3332
Add a userspace API to get, set and enumerate the media format on a subdev pad. The format at the output of a subdev usually depends on the format at its input(s). The try format operation is thus not suitable for probing format at individual pads, as it can't modify the device state and thus can't remember the format tried at the input to compute the output format. To fix the problem, pass an extra argument to the get/set format operations to select the 'try' or 'active' format. The try format is used when probing the subdev. Setting the try format must not change the device configuration but can store data for later reuse. Data storage is provided at the file-handle level so applications probing the subdev concurently won't interfere with each other. The active format is used when configuring the subdev. It's identical to the format handled by the usual get/set operations.

2011-03-22[media] v4l: v4l2_subdev pad-level operationsLaurent Pinchart1-0/+4
Add a v4l2_subdev_pad_ops structure for the operations that need to be performed at the pad level such as format-related operations. Pad format-related operations use v4l2_mbus_framefmt instead of v4l2_format.

2011-03-22[media] v4l: subdev: Add new file operationsLaurent Pinchart2-3/+20
V4L2 sub-devices store pad formats and crop settings in the file handle. To let drivers initialize those settings properly, add an open operation that is called when the subdev is opened as well as a corresponding close operation.
