From 07c13bb78c8b8a9cb6ee169659528945038d5e85 Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Thu, 14 Jun 2018 09:29:22 +0200 Subject: [PATCH] drm: Change deadlock-avoidance algorithm for the modeset locks. For modeset locks we don't expect a high number of contending transactions so change algorithm from Wait-Die to Wound-Wait.
