V4L framework progress

This page contains the status of all drivers with respect to their adoption of all the new structures that the V4L framework offers.

This should help in identifying those drivers that need more work.

It is expected that this page will be continuously updated whenever new conversion tasks appear.

Note: the driver lists are not yet complete. This is work in progress.

Bridge Drivers

driver

The driver name

interface

Type of bridge interface

V4L API

Whether the driver implements the V4L2 API or still uses the old V4L1 API

v4l2_device

Whether the driver uses struct v4l2_device

video_ioctls

Whether the driver uses the video_ioctl2 fops .ioctl op

have hardware

Who can test this driver?

AW = Andy Walls

DH = Devin Heitmueller

HdG = Hans de Goede

HV = Hans Verkuil

LP = Laurent Pinchart

MI = Mike Isely

BKL

Still uses the Big Kernel Lock
