From ea3aba8482be6f3e4815f4014fa7302fc77c9c3f Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Tue, 21 May 2013 05:11:35 -0300 Subject: [media] videobuf2: Add support for file access mode flags for DMABUF exporting Currently it is not possible for userspace to map a DMABUF exported buffer with write permissions. This patch allows to also pass O_RDONLY/O_RDWR when exporting the buffer, so that userspace may map it with write permissions.

These helpers will only be useful for drivers that use same mutex for both OUTPUT and CAPTURE queue, which is the case for all currently in tree v4l2 m2m drivers.

Nobody maintains these drivers anymore. But unfortunately the v4l2-int-device API is used by out-of-tree drivers (MXC platform). This is a very bad situation since as long as this deprecated API stays in the kernel there is no reason for those out-of-tree drivers to convert. This patch moves v4l2-int-device and the two drivers that depend on it to staging in preparation for their removal. If someone would be interested in getting these drivers to work, then start with this since it's not very far from the state where they used to work: The branch is n800-cam. Porting to up-to-date APIs can then be done. David might have done some work in that area, so check with him first.

Total number of lines in a frame in both systems are an odd number so the two fields will have different length. In the 625 line standard ("PAL") the odd field of the frame is transmitted first, while in the 525 standard ("NTSC") the even field is transmitted first. This adds the possibility to change output config between the fields and standards. This setting will reduce the "format-jitter" on the signal sent by the pixelport moving the difference between the fields to vertical front/back-porch only.

It was placed in vb2_queue_or_prepare_buf() to prevent racing with other vb2 calls. The only way I can see that a race can happen is when two threads queue the same buffer. The solution for that it to introduce a PREPARING state. Moving it down offers opportunities to simplify the code.

This means applications no longer need to know how many buffers need to be queued before STREAMON can be called. This is particularly useful for output stream I/O. If a DMA engine needs at least X buffers before it can start streaming, then for applications to get a buffer out as soon as possible they need to know the minimum number of buffers to queue before STREAMON can be called. You can't just try STREAMON after every buffer since on failure STREAMON will dequeue all your buffers. (Is that a bug or a feature? Frankly, I'm not sure). This patch simplifies applications substantially: they can just call STREAMON at the beginning and then start queuing buffers and the DMA engine will kick in automagically once enough buffers are available. This also fixes using write() to stream video: the fileio implementation calls streamon without having any queued buffers, which will fail today for any driver that requires a minimum number of buffers.
