From bc5d587a80b64fb3e0a5ea8067e6317fbca2bbc5 Mon Sep 17 00:00:00 2001 From: Alex Smith Date: Tue, 21 Mar 2017 17:02:33 +0000 Subject: [PATCH] radv: Invalidate L2 for TRANSFER_WRITE barriers CP DMA and PKT3_WRITE_DATA (in CmdUpdateBuffer) don't (currently) write through L2. Therefore, to make these writes visible to later accesses we must invalidate L2 rather than just writing it back, to avoid the possibility that stale data is read through L2.
