Subject: [PATCH] drm/amd/powerplay/smu7_hwmgr: replace blocking delay with non-blocking
Date: Thu, 30 May 2019 02:08:21 +0200 [thread overview]
Message-ID: <20190530000819.GA25416@obi-wan> (raw)
This driver currently contains a repeated 500ms blocking delay call
which causes frequent major buffer underruns in PulseAudio. This patch
fixes this issue by replacing the blocking delay with a non-blocking
sleep call.
