From c84444ea85b2cf749eaf78dd97430231d92fa618 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Tue, 28 Jun 2016 17:15:57 -0600 Subject: [PATCH] svga: use SVGA3D_vgpu10_BufferCopy() for buffer copies So that we do copies host-side rather than in the guest with map/memcpy. Tested with piglit arb_copy_buffer-subdata-sync test and new arb_copy_buffer-intra-buffer-copy test.
