--- Comment #69 from Michel Dänzer michel@daenzer.net --- (In reply to Marek Olšák from comment #67)
Primitives aren't reordered with DPBB. Primitives can't also survive a barrier with DPBB. DPBB has no effect on behavior, it just changes how PS wavefronts are formed.
Is there any way that could affect the glamor shader which samples from one area of a buffer and draws to another (non-overlapping) area of the same buffer?
What is the reason for radeonsi disabling DPBB for blits?
