From: Chris Wilson Date: Tue, 29 Jan 2019 20:52:28 +0000 (+0000) Subject: drm/i915: Remove the intel_engine_notify tracepoint X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3df0bd19193c47c48b7904e5f41c3041a431da33;p=openwrt%2Fstaging%2Fblogic.git drm/i915: Remove the intel_engine_notify tracepoint The global seqno is defunct and so we have no meaningful indicator of forward progress for an engine. You need to listen to the request signaling tracepoints instead.
