Subject: [RFC PATCH 153/162] drm/i915: Implement eviction locking v2
Date: Fri, 27 Nov 2020 12:07:09 +0000 [thread overview]
Message-ID: <20201127120718.454037-154-matthew.auld@intel.com> (raw)
In-Reply-To: <20201127120718.454037-1-matthew.auld@intel.com>
From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Use a separate acquire context list and a separate locking function
for objects that are locked for eviction. These objects are then
properly referenced while on the list and can be unlocked early in
the ww transaction.
