+Subject: [PATCH] MMFMWK-6930 [glplugin] Accelerate gldownload with
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+1) Propose a physical buffer pool to upstream in gldownload
+2) Bind the physical buffer with texture via dirctviv
+3) In gldownload, wrap the physical buffer to gstbuffer, pass to
+ downstream plugins.
+4) Add some configure check for g2d and phymem
+
+Upstream-Status: Inappropriate [i.MX specific]
+
