From 83af8213adbe34fb84a98b7524aa82d74fb7a7be Mon Sep 17 00:00:00 2001 From: Matthew Brost Date: Thu, 9 Sep 2021 09:47:26 -0700 Subject: [PATCH] drm/i915/guc: Process all G2H message at once in work queue Rather than processing 1 G2H at a time and re-queuing the work queue if more messages exist, process all the G2H in a single pass of the work queue.
