Hi everybody,
Here is the ninth version of the media controller core and V4L2 patches.
Quick reminder for those who missed the previous version. let me quote the documentation (Documentation/DocBook/v4l/media-controller.xml).
"Discovering a [media] device internal topology, and configuring it at
runtime,
is one of the goals of the media controller API. To achieve this, hardware devices are modelled as an oriented graph of building blocks called entities connected through pads."
The code has been extensively reviewed by the V4L community, and this
version
is the first one to incorporate comments from the ALSA community (big thanks to Mark Brown and Clemens Ladisch). Two issues are not fully addressed yet, namely power management (I need to discuss this some more with the ALSA developers to really understand their requirements) and entities type names. I'm still posting this for review, as other developers have showed interest
in
commenting on the code.
I want to emphasize once again that the media controller API does not
replace
the V4L, DVB or ALSA APIs. It complements them.
The first user of the media controller API is the OMAP3 ISP driver. You can find it (as well as these patches and other V4L-specific patches) in a git
tree
at http://git.linuxtv.org/pinchartl/media.git (media-0005-omap3isp branch).
The
OMAP3 ISP driver patches are regularly posted for review on the linux-media list.
