That don't result in any changes in tooling, just silences this perf

* I915_CONTEXT_PARAM_RINGSIZE:

* Sets the size of the CS ringbuffer to use for logical ring contexts. This

*
* Only reliably possible to be set prior to first use, i.e. during
* construction. At any later point, the current execution must be flushed as
* the ring can only be changed while the context is idle. Note, the ringsize
* can be specified as a constructor property, see
* I915_CONTEXT_CREATE_EXT_SETPARAM, but can also be set later if required.
*
* Only applies to the current set of engine and lost when those engines
* are replaced by a new mapping (see I915_CONTEXT_PARAM_ENGINES).
*
* Must be between 4 - 512 KiB, in intervals of page size [4 KiB].
* Default is 16 KiB.
