media: v4l: Add 14-bit raw greyscale pixel format

2020-03-20T08:00:56+00:00

The new format is called V4L2_PIX_FMT_Y14. Like V4L2_PIX_FMT_Y10 and V4L2_PIX_FMT_Y12 it is stored in two bytes per pixel but has only two unused bits at the top. Signed-off-by: Daniel Glöckner Signed-off-by: Hans Verkuil Acked-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

media: v4l: Add 14-bit raw bayer pixel formats

2020-03-20T08:00:23+00:00

The formats added by this patch are: V4L2_PIX_FMT_SBGGR14 V4L2_PIX_FMT_SGBRG14 V4L2_PIX_FMT_SGRBG14 V4L2_PIX_FMT_SRGGB14 Signed-off-by: Jouni Ukkonen Signed-off-by: Sakari Ailus [dg@emlix.com: rebased onto current media_tree] Signed-off-by: Daniel Glöckner Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l: link dt-bindings and uapi

2020-03-12T15:29:52+00:00

Since we expose the definition to the dt-bindings we need to keep those definitions in sync. To address this the patch adds a simple cross reference to the dt-bindings. Signed-off-by: Marco Felsch Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l2-core: fix v4l2_buffer handling for time64 ABI

2020-01-03T14:50:21+00:00

The v4l2_buffer structure contains a 'struct timeval' member that is defined by the user space C library, creating an ABI incompatibility when that gets updated to a 64-bit time_t. As in v4l2_event, handle this with a special case in video_put_user() and video_get_user() to replace the memcpy there. Since the structure also contains a pointer, there are now two native versions (on 32-bit systems) as well as two compat versions (on 64-bit systems), which unfortunately complicates the compat handler quite a bit. Duplicating the existing handlers for the new types is a safe conversion for now, but unfortunately this may turn into a maintenance burden later. A larger-scale rework of the compat code might be a better alternative, but is out of scope of the y2038 work. Sparc64 needs a special case because of their special suseconds_t definition.

media: v4l2-core: fix VIDIOC_DQEVENT for time64 ABI

2020-01-03T14:47:57+00:00

The v4l2_event structure contains a 'struct timespec' member that is defined by the user space C library, creating an ABI incompatibility when that gets updated to a 64-bit time_t. While passing a 32-bit time_t here would be sufficient for CLOCK_MONOTONIC timestamps, simply redefining the structure to use the kernel's __kernel_old_timespec would not work for any library that uses a copy of the linux/videodev2.h header file rather than including the copy from the latest kernel headers. This means the kernel has to be changed to handle both versions of the structure layout on a 32-bit architecture. The easiest way to do this is during the copy from/to user space.

media: v4l2: abstract timeval handling in v4l2_buffer

2020-01-03T14:43:35+00:00

As a preparation for adding 64-bit time_t support in the uapi, change the drivers to no longer care about the format of the timestamp field in struct v4l2_buffer. The v4l2_timeval_to_ns() function is no longer needed in the kernel after this, but there is userspace code relying on it to be part of the uapi header.

media: vb2: add V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF

2019-10-21T10:37:57+00:00

This patch adds support for the V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF flag. It also adds a new V4L2_BUF_CAP_SUPPORTS_M2M_HOLD_CAPTURE_BUF capability. Drivers should set vb2_queue->subsystem_flags to VB2_V4L2_FL_SUPPORTS_M2M_HOLD_CAPTURE_BUF to indicate support for this flag. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
