From 4750c4e5439f5c2689051ac072003cc3a2ff5c1b Mon Sep 17 00:00:00 2001 From: Charmaine Lee Date: Thu, 29 Sep 2016 16:41:21 -0700 Subject: [PATCH] svga: set rendered_to flag with texture uploaded using TransferFromBuffer command This patch sets the rendered_to flag for the texture subresource that is uploaded using the TransferFromBuffer command. This is to ensure that the subresource will be read back or invalidated before it will be directly mapped to. This makes sure that the content of the GB surface will not be accidentally overwritten by the device at suspend/resume time.
