If the intent here is to consolidate/abstract things, this patch isn't
the way I'm afraid.
Namely, it drops support for software only pipe-driver. It also
removes pipe-driver support for dri, xa and vl-based modules. All of
which used to work fine last time I've tested them (admittedly ~6
The idea that I have in mind is roughly as:
1) abstract most of the 'target-helpers' as 'static' pipe-loader,
providing pipe-loader like interface.
2) drop the ifdefs in the former, add dummy
3) remove all the ifdefs in the state-trackers.
4) add a configure switch that allows one to toggle/choose which how
the modules will be build. default to 'mega' (static).
If you want to hack on that be my guest, but be aware that the
pipe-loader interface has some non-obvious fd ownership patterns ;-)
Atm, I'm having fun with drm_gralloc and mesa. Expect patches on that
one later on today/tomorrow.
