We also add the concept of modifiers already employed in DRM to expose HW-specific formats (like tiled or compressed formats) and allow exchanging this information with the DRM subsystem in a consistent way. Note that only V4L2_BUF_TYPE_VIDEO_[OUTPUT,CAPTURE] are accepted in v4l2_ext_format, other types will be rejected if you use the {G,S,TRY}EXT_FMT ioctls. New hooks have been added to v4l2_ioctl_ops to support those new ioctls in drivers, but, in the meantime, the core takes care of converting {S,G,TRY}_EXT_FMT requests into {S,G,TRY}_FMT so that old drivers can still work if the userspace app/lib uses the new ioctls. The conversion is also done the other around to allow userspace apps/libs using {S,G,TRY}_FMT to work with drivers implementing the _ext_ hooks. Signed-off-by: Boris Brezillon Signed-off-by: Helen Koike --- Changes in v4: - Use v4l2_ext_pix_format directly in the ioctl, drop v4l2_ext_format, making V4L2_BUF_TYPE_VIDEO_[OUTPUT,CAPTURE] the only valid types. - Add reserved fields - Removed num_planes from struct v4l2_ext_pix_format - Removed flag field from struct v4l2_ext_pix_format, since the only defined value is V4L2_PIX_FMT_FLAG_PREMUL_ALPHA only used by vsp1, where we can use modifiers, or add it back later through the reserved bits. - In v4l2_ext_format_to_format(), check if modifier is != MOD_LINEAR && != MOD_INVALID - Fix type assignment in v4l_g_fmt_ext_pix() - Rebased on top of media/master (post 5.8-rc1) Changes in v3: - Rebased on top of media/master (post 5.4-rc1) Changes in v2: - Move the modifier in v4l2_ext_format (was formerly placed in v4l2_ext_plane) - Fix a few bugs in the converters and add a strict parameter to allow conversion of uninitialized/mis-initialized objects --- drivers/media/v4l2-core/v4l2-dev.c | 21 +- drivers/media/v4l2-core/v4l2-ioctl.c | 585 +++++++++++++++++++++++---- include/media/v4l2-ioctl.h | 34 ++ include/uapi/linux/videodev2.h | 55 +++ 4 files changed, 614 insertions(+), 81 deletions(-) diff --git a/drivers/media/v4l2-core/v4l2-dev.c b/drivers/media/v4l2-core/v4l2-dev.c index a593ea0598b55..e1829906bc086 100644 --- a/drivers/media/v4l2-core/v4l2-dev.c +++ b/drivers/media/v4l2-core/v4l2-dev.c @@ -607,25 +607,37 @@ static void determine_valid_ioctls(struct video_device *vdev) set_bit(_IOC_NR(VIDIOC_ENUM_FMT), valid_ioctls);
