The v4l2_pix_format structure has no reserved field. It is embedded in the v4l2_framebuffer structure which has no reserved fields either, and in the v4l2_format structure which has reserved fields that were not previously required to be zeroed out by applications. To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer structure, and use the priv field as a magic value to indicate that the application has set all v4l2_pix_format extended fields and zeroed all reserved fields following the v4l2_pix_format field in the v4l2_format structure. The availability of this API extension is reported to userspace through the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the priv field is still set to the magic value at [GS]_FMT return wouldn't be enough, as older kernels don't zero the priv field on return. To simplify the internal API towards drivers zero the extended fields and set the priv field to the magic value for applications not aware of the extensions.

After commits 890676c6 (kbuild: Use relative path when building in the source tree) and 9da0763b (kbuild: Use relative path when building in a subdir of the source tree), the $(srctree) variable can be a relative path. This breaks Documentation/DocBook/media/Makefile, because it tries to create symlinks from a subdirectory of the object tree to the source tree. Fix this by using a full path in this case.

Describe how devices are registered using the drm_*_init() functions. Adding this to docbook requires a largish set of changes to the comments in drm_{pci,usb,platform}.c since they are doxygen-style rather than proper kernel-doc and therefore mess with the docbook generation. While at it, mark usage of drm_put_dev() as discouraged in favour of calling drm_dev_unregister() and drm_dev_unref() directly.

For atomic, it will be quite necessary to not need to care so much about locking order. And 'state' gives us a convenient place to stash a ww_ctx for any sort of update that needs to grab multiple crtc locks. Because we will want to eventually make locking even more fine grained (giving locks to planes, connectors, etc), split out drm_modeset_lock and drm_modeset_acquire_ctx to track acquired locks. Atomic will use this to keep track of which locks have been acquired in a transaction. v1: original v2: remove a few things not needed until atomic, for now v3: update for v3 of connection_mutex patch.. v4: squash in docbook v5: doc tweaks/fixes Signed-off-by: NRob Clark <robdclark@gmail.com> Reviewed-by: NDaniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: NDave Airlie <airlied@redhat.com>

This event indicates that the video device has encountered a source parameter change during runtime. This can typically be a resolution change detected by a video decoder OR a format change detected by an input connector. This needs to be nofified to the userspace and the application may be expected to reallocate buffers before proceeding. The application can subscribe to events on a specific pad or input port which it is interested in.
