Hi Rob,
Thanks for the answer.so as per the definitions I understand the below points.
a) frame buffer here signifies the scan out buffer which encompasses complete display.
b)when I see the definition of plane in the doc book it says " planes are associated with a frame buffer to crop a portion of the image source and optionally scale it to destination size". I assume this is not the same frame buffer as point a.
c)planes are overlayed or blended over the scanout buffer.
Regards,
Anand

although the docbook probably should be updated (now that we have
primary-planes) to read something more like: "...that provide a source
of pixels to scanout to a plane"
(since a plane is basically the part of display controller block that
reads in the pixel data from the fb)
