Hi!
Compiling the media drivers out of tree with media_build does not handle
FRAME_VECTOR correctly.
My kernel sources have FRAME_VECTOR but it is not enabled. So all
modules depending on it (e.g. VIDEOBUF2_MEMOPS) will fail to load
because the relevant functions cannot be found.
I see two options:
1. Modify the real kernel sources to allow FRAME_VECTOR be enabled via
config (either y or m).
I locally just modified my kernel's mm/KConfig like this:
config FRAME_VECTOR
- bool
+ tristate "enable frame_vector for external modules"
2. Change media_build to supply a replacement when it is not enabled in
the system kernel.
Regards
Matthias
