Subject: [PATCH 30/31] drm/i915: Finalize contexts in GEM_CONTEXT_CREATE on version 13+
Date: Tue,  8 Jun 2021 23:36:12 -0500	[thread overview]
Message-ID: <20210609043613.102962-31-jason@jlekstrand.net> (raw)
In-Reply-To: <20210609043613.102962-1-jason@jlekstrand.net>

All the proto-context stuff for context creation exists to allow older
userspace drivers to set VMs and engine sets via SET_CONTEXT_PARAM.
Drivers need to update to use CONTEXT_CREATE_EXT_* for this going
forward.  Force the issue by blocking the old mechanism on any future
hardware generations.
