i've seen a brief explanation on #lima - the architecture of gallium
simply doesn't comprehend shaders, specifically shader compilers
(whatever they are). thus it just... doesn't fit, and therefore the
simplest thing to do initially is bypass the whole lot, and come back
to gallium later.
btw although i understood what you said about shaders being "mini
ALUs/CPUs", gordan, i still don't grok what they're actually _for_.
why do you need a group of parallel "shader" processors in the first
place (as opposed to a general-purpose SMP CPU with a stonking-great
DSP up its arse)? what the hell are the damn things doing? :)
