From 85c83ea915ed3980c816c7bc44b2aca5c81ee1e2 Mon Sep 17 00:00:00 2001 From: Gurchetan Singh Date: Tue, 21 Sep 2021 16:20:21 -0700 Subject: drm/virtio: implement context init: allocate an array of fence contexts We don't want fences from different 3D contexts (virgl, gfxstream, venus) to be on the same timeline. With explicit context creation, we can specify the number of ring each context wants. Execbuffer can specify which ring to use.
