Hi.
There's not much to say here, just replacing the screen_init
stateobj with direct pushbuffer emission.
We don't need to store all the usless state from init, and the
constant buffer relocations which currently don't work if the
addresses change (because the method CB_DEF_SET isn't
among them (not an address)) become effective.
Thoughts, ack / nack ?
Thanks,
Christoph

Subject: [PATCH] nv50: get rid of the screen_init stateobj
Relocations of per-screen buffers are now emitted directly,
and include the necessary method to get changes in constbuf
addresses committed to the hw.
It should also be a bit cheaper than the way stateobjs emit
relocation markers, use a little less pushbuf space.
