media: uapi: Use unsigned int values for assigning bits in u32 fields

2023-05-25T14:21:22+00:00

Use unsigned int values annoted by "U" for u32 fields. While this is a good practice, there doesn't appear to be a bug that this patch would fix. The patch has been generated using the following command: perl -i -pe 's/\([0-9]+\K < Reviewed-by: Laurent Pinchart Signed-off-by: Hans Verkuil

media: media.h: remove unneeded inclusion

2022-04-24T07:27:37+00:00

Commit b3b7a9f138b7 ("[media] media-device: Use u64 ints for pointers") added this #include , presumably in order to use uintptr_t. Now that it is gone, we can compile this for userspace without .

media: media.h: Add new media link type

2022-04-24T06:58:16+00:00

To describe in the kernel the connection between devices and their supporting peripherals (for example, a camera sensor and the vcm driving the focusing lens for it), add a new type of media link to introduce the concept of these ancillary links. Add some elements to the uAPI documentation to explain the new link type, their purpose and some aspects of their current implementation.

media: uapi: Add an entity type for Image Signal Processors

2021-01-12T16:05:37+00:00

Add and document a media entity type for Image Signal Processor devices. Surprisingly we didn't have one, so add one now. More or less all ISP drivers should use this type instead of what they currently are using (or not using anything).

media: media.h: Fix shifting signed 32-bit value by 31 bits problem

2019-06-21T20:45:38+00:00

Fix MEDIA_ENT_ID_FLAG_NEXT to use "U" cast to avoid shifting signed 32-bit value by 31 bits problem. This isn't a problem for kernel builds with gcc. This could be problem since this header is part of public API which could be included for builds using compilers that don't handle this condition safely resulting in undefined behavior.

media: uapi/linux/media.h: add request API

2018-08-31T15:04:23+00:00

Define the public request API. This adds the new MEDIA_IOC_REQUEST_ALLOC ioctl to allocate a request and two ioctls that operate on a request in order to queue the contents of the request to the driver and to re-initialize the request.

media: media.h: remove linux/version.h include

2018-07-27T11:52:39+00:00

The media.h public header is one of only three public headers that include linux/version.h. Drop it from media.h. It was only used for an obsolete define. It has to be added to media-device.c, since that source relied on media.h to include it. Acked-by: Sakari Ailus Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
