From 6bbeae35b67b339b81e42c9ab56789788491dc00 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Wed, 20 Mar 2019 09:36:12 +0100 Subject: [PATCH] drm/virtio: add virtio-gpu-features debugfs file. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This file prints which features the virtio-gpu device has. Also add "virtio-gpu-" prefix to the existing fence file, to make clear this is a driver-specific debugfs file.
