> i915/gem_exec_parse: Switch to a fixed timeout for basic-allocations
>
> basic-allocations was written to demonstrate a flaw in our continual
> reallocation of cmdparser shadow bo, largely fixed by keeping a small
> cache of bo of different lengths (to speed up the search for the correct
> sized bo). We only care enough to exercise the slowdown by submitting
> lots of execbufs, and can see the effect of bo caching on the rate, so
> replace the fixed number of iterations with a timeout and count how many
> batches we could submit instead.
>
> Similarly, we now do not need to wait for all of our queue to complete
> as we can tell the kernel to drop the queue instead.

Still not fixing all the failure, as they pretty much fail every single drmtip
run on the chromebooks:
