Enabling this option makes Intel Gen8-11 hardware load the 'iris'
driver by default instead of the older 'i965' driver.
Regardless of how this option is set, users can still override which
driver the loader selects via two methods. The first is to create a
~/.drirc or /etc/drirc file with the following snippet:
<driconf>
<device driver="loader" kernel_driver="i915">
<option name="dri_driver" value="i965" />
</device>
</driconf>
The other option is to set an environment variable:
export MESA_LOADER_DRIVER_OVERRIDE=i965
For now, "prefer_iris" defaults to i965 (the historical choice).
A separate future patch will change the default driver to iris.
