From c3d36a2e1a87a4aded662db7a5d320ee7ac3a8b5 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Mon, 25 May 2015 21:14:13 -0400 Subject: [PATCH] nv30/draw: allocate vertex buffers in gart These are only used once per draw, so it makes sense to keep them in GART. Also take this opportunity to modernize the buffer mapping API usage.
