From 396bcb41e035df7b98fb150ca950bf213e70ae7b Mon Sep 17 00:00:00 2001 From: Christian König Date: Mon, 9 Oct 2017 14:45:09 +0200 Subject: drm/amdgpu: partial revert VRAM lost handling v2 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Keep blocking the CS, but revert everything else. Mapping BOs and info IOCTL are harmless and can still happen even when VRAM content ist lost.
