media: media/v4l2: remove V4L2_FLAG_MEMORY_NON_CONSISTENT flag

2020-09-14T13:28:06+00:00

The patch partially reverts some of the UAPI bits of the buffer cache management hints. Namely, the queue consistency (memory coherency) user-space hint because, as it turned out, the kernel implementation of this feature was misusing DMA_ATTR_NON_CONSISTENT. The patch reverts both kernel and user space parts: removes the DMA consistency attr functions, rolls back changes to v4l2_requestbuffers, v4l2_create_buffers structures and corresponding UAPI functions (plus compat32 layer) and cleans up the documentation.

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59+00:00

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

media: videobuf2: Print videobuf2 buffer state by name

2020-07-19T12:25:36+00:00

For debugging purposes, seeing the state integer representation is really inconvenient. Improve this and be developer-friendly by printing the state name instead. Suggested-by: Nicolas Dufresne Signed-off-by: Ezequiel Garcia Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: tpg: Add function to return colors' order of test image

2020-07-19T11:38:56+00:00

Currently there is no method to know the correct order of the colors for a test image generated by tpg. Write a function that returns a string of colors' order given a tpg. It returns a NULL pointer in case of test patterns which do not have a well defined colors' order. Hence add a NULL check for text in tpg_gen_text().

media: tpg: change char argument to const char

2020-07-19T11:38:30+00:00

Change the argument of type char * to const char * for function tpg_gen_text(). This function should take in a const char * as opposed to char * as it does not make changes to the text. This issue was found while passing the order of colors of tpg generated test image (which is a const char *) to this function.

media: Add V4L2_TYPE_IS_CAPTURE helper

2020-07-19T06:13:24+00:00

It's all too easy to get confused by the V4L2_TYPE_IS_OUTPUT macro, when it's used as !V4L2_TYPE_IS_OUTPUT. Reduce the risk of confusion with macro to explicitly check for the CAPTURE queue type case. This change does not affect functionality, and it's only intended to make the code more readable.

media: videobuf2: Fix length check for single plane dmabuf queueing

2020-07-04T10:41:57+00:00

Check against length in v4l2_buffer rather than vb2_buffer when the buffer is a dmabuf. This makes the single plane test the same as the existing multiplanar test. Signed-off-by: John Cox Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: vb2: Print the queue pointer in debug messages

2020-07-04T10:32:10+00:00

When debugging issues that involve more than one video queue, messages related to multiple queues get interleaved without any easy way to tell which queue they relate to. Fix this by adding a queue name to vb2_queue, and printing it in all debug messages in the vb2 core and V4L2 layers. If the name isn't set by drivers, it is automatically filled with the queue direction and address. Signed-off-by: Laurent Pinchart Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
