From 7a453fb82f869ea919aefb4943c7d24194c98698 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 30 Mar 2017 15:50:40 +0100 Subject: [PATCH] drm/i915: Remove redudant wait for each engine to idle from seqno wrap Having added the wait upon each engine to idle into the central i915_gem_wait_for_idle(), we can remove the now redundant wait from reset_all_global_seqno(). This has the advantage of removing the late detection of an error (an engine still busy) which left the seqno reset only partially complete (though it should be safe enough!).
