Subject: [GIT PULL 16/22] intel_th: msu: Correct the block wrap detection
Date: Fri, 3 May 2019 11:44:49 +0300 [thread overview]
Message-ID: <20190503084455.23436-17-alexander.shishkin@linux.intel.com> (raw)
In-Reply-To: <20190503084455.23436-1-alexander.shishkin@linux.intel.com>
In multi window mode the MSU will set "window wrap" bit to indicate block
wrapping as well. Take this into account when checking data blocks.
