From 635fe3e1927f812a69a68ec3e03d9ab7a2c3a5d9 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Sun, 28 Nov 2010 03:29:55 +0800 Subject: [PATCH] st/vega: vg_manager should care about only the color buffer. Move depth/stencil buffer, blend texture view, and alpha mask view creation to vg_context.c. --- src/gallium/state_trackers/vega/vg_context.c | 184 +++++++++++++++++++ src/gallium/state_trackers/vega/vg_manager.c | 182 ------------------ 2 files changed, 184 insertions(+), 182 deletions(-) diff --git a/src/gallium/state_trackers/vega/vg_context.c b/src/gallium/state_trackers/vega/vg_context.c index b9dbc4f00b0..e76a65604be 100644 --- a/src/gallium/state_trackers/vega/vg_context.c +++ b/src/gallium/state_trackers/vega/vg_context.c @@ -34,6 +34,7 @@ #include "st_inlines.h" #include "vg_manager.h" #include "api.h" +#include "mask.h" #include "pipe/p_context.h" #include "util/u_inlines.h" @@ -44,6 +45,7 @@ #include "util/u_memory.h" #include "util/u_blit.h" #include "util/u_sampler.h" +#include "util/u_format.h" struct vg_context *_vg_context = 0;
