> We add a PMU counter to expose the number of requests with resolved
> dependencies waiting for a slot on the GPU to run.
> 
> This is useful to analyze the overall load of the system.

> v2: Don't limit to gen8+.
> 
> v3:
>  * Rebase for dynamic sysfs.
>  * Drop currently executing requests.
> 
> v4:
>  * Sync with internal renaming.
>  * Drop floating point constant. (Chris Wilson)
> 
> v5:
>  * Change scale to 1024 for faster arithmetics. (Chris Wilson)
