From 4f4907d69f9020ce17aef21b6431d2dd65e01982 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 22 Apr 2009 16:24:42 -0700 Subject: intel: Take advantage of GL_READ_ONLY_ARB to map to GEM bo_map write flag. This is a CPU win in general, but in particular reduces the pain of Mesa's calculation of min/max indices in DrawElements (wtf?). --- src/mesa/drivers/dri/intel/intel_buffer_objects.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'src/mesa/drivers/dri/intel') diff --git a/src/mesa/drivers/dri/intel/intel_buffer_objects.c b/src/mesa/drivers/dri/intel/intel_buffer_objects.c index b7c7eeb368..c849e4869e 100644 --- a/src/mesa/drivers/dri/intel/intel_buffer_objects.c +++ b/src/mesa/drivers/dri/intel/intel_buffer_objects.c @@ -204,9 +204,8 @@ intel_bufferobj_map(GLcontext * ctx, { struct intel_context *intel = intel_context(ctx); struct intel_buffer_object *intel_obj = intel_buffer_object(obj); + GLboolean read_only = (access == GL_READ_ONLY_ARB); - /* XXX: Translate access to flags arg below: - */ assert(intel_obj); if (intel_obj->region) @@ -217,7 +216,7 @@ intel_bufferobj_map(GLcontext * ctx, return NULL; } - dri_bo_map(intel_obj->buffer, GL_TRUE); + dri_bo_map(intel_obj->buffer, !read_only); obj->Pointer = intel_obj->buffer->virtual; return obj->Pointer; } -- cgit v1.2.3
