fwiw, the freedreno/kgsl bare ioctls are actually against the non-drm
device file..  freedreno/msm is the stuff for the upstream drm/msm
driver.

background: downstream android kernel w/ kgsl kernel driver has this
shim drm driver which is really just for getting flink names + non drm
device for everything else.  It's kinda bonghits, really just exists
to give folks stuck w/ android drivers a fighting chance.  And due to
different versions of kgsl floating around on the many different
android kernel branches, odds are still pretty grim (which is why kgsl
backend is disabled by default)

I guess technically they could still use drmIoctl() but it seemed a bit strange

BR,
