From: Timothy Arceri Date: Thu, 23 Mar 2017 06:19:36 +0000 (+1100) Subject: mesa/marshal: add custom BufferData/BufferSubData marshalling X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=adced4a2f9d017ae126a438f97eb305fa0ca3bd0;p=mesa.git mesa/marshal: add custom BufferData/BufferSubData marshalling GL_AMD_pinned_memory requires memory to be aligned correctly, so we skip marshalling in this case. Also copying the data defeats the purpose of EXTERNAL_VIRTUAL_MEMORY_BUFFER_AMD. Fixes GL_AMD_pinned_memory piglit tests when glthread is enabled.
