[PATCH 10/13] nv50: proper linkage between VP and FP
Christoph Bumiller
e0425955 at student.tuwien.ac.at
Sat Sep 12 12:30:49 PDT 2009
This moves construction of the mapping between VP outputs
and FP inputs into validation.
The map also contains slots for special outputs like clip
distance and point size, so we need to at least merge the
VP related and FP related parts on validation if we want
to support those.
Now we match every single FP input component with results
from the VP and leave those not read out of the map, or
replace those not written by 0 (xyz) or 1 (w).
The bitmap indicating linear interpolants is also filled,
and flat FP inputs are mapped in only after non-flat ones,
as is required.
Furthermore, we can save some space by only fetching VP
attrs we actually use, and avoid wasting any output regs
because of TGSI using less than 4 components.
