And imo we can also pull in the burst size hack since imo that's what we want - afaik the hw has some bits to select the burst size between 4, 8, ... entries, and atm we always set it to 8. And Bspec explicitly says that setting the fifo to something smaller than burst size will lead to tears. So the patch with a pimped commit message + bit a better comment is good to go. Originally I wanted to implement "proper" burst size selection, but that ran afoul of the general gen2/3 wm mess. Aside: We might want to give intel_calculate_wm some i9xx prefix, since it's very much not generic.
