From ff2ac58a45914cb65ae4bdc716d108193a867038 Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Tue, 24 Jan 2017 14:12:29 +0100 Subject: [PATCH] virtio-gpu: disable VIRGL with BE kernel VIRTIO_GPU_F_VIRGL is added in features list only for LE kernel, so we must check for it only on LE kernel, otherwise virtio_has_feature() calls BUG() and crashes the kernel.
