--- Comment #4 from Kenneth Graunke <kenneth at whitecape.org> ---
Total needs is 9, URB chunks is 8.

Notably, brw->urb.size == 64, but devinfo->urb.size == 192, so we're probably
getting things out of sync when changing L3 configurations.

Oddly KBL GT1 has a devinfo->urb.size of 192 as well, and still uses
chv_l3_configs, yet it works fine.
