From 48ad7751dbd1facd5500c4718698aec550aaea6e Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Mon, 29 Apr 2019 15:08:24 -0700 Subject: [PATCH] drm/virtio: trace drm_fence_emit For most drivers, drm_fence_init is followed by drm_fence_emit immediately. But for our driver, they are done separately. We also don't know the fence seqno until drm_fence_emit.
