One scenario under recent discussion is that of having a thundering herd in i915_wait_request - where the overhead of waking up every waiter for every batchbuffer was significantly impacting customer throughput. This benchmark tries to replicate something to that effect by having a large number of consumers generating a busy load (a large copy followed by lots of small copies to generate lots of interrupts) and tries to wait upon all the consumers concurrenctly (to reproduce the thundering herd effect). To measure the overhead, we have a bunch of cpu hogs - less kernel overhead in waiting should allow more CPU throughput. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
