on bug 68451
from Marek Olšák
Feel free to do some benchmarking if you want. The question is why this code at the end of the function didn't set one of the flush flags: r600_flag_resource_cache_flush(rctx, dst); Constants are usually read with the shader cache and indirect addressing of the constants goes through the vertex cache. Also some chips don't have the vertex cache, so they have to use the texture cache instead. That's why both VERTEX and CONST work for some chips in this situation. The purpose of the flags is to express what type of buffer was changed. The flushing code will then figure out which cache should be flushed.
