From bf36dea17623b65cfbbe6219bfea1326255a89b6 Mon Sep 17 00:00:00 2001 From: Gurchetan Singh Date: Wed, 23 Sep 2020 17:32:02 -0700 Subject: [PATCH] drm/virtgpu api: cross-device feature This feature was recently added to virtio-gpu, lets make it userspace queryable. It's an error to use BLOB_FLAG_USE_CROSS_DEVICE when this feature is not present.
