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?
As long as the blits are truly non-overlapping, DPBB doesn't affect it.
What is the reason for radeonsi disabling DPBB for blits?
because it's not useful for blits and it might add latency because of binning.
