From e928c34d3ec54bb8a6b80036e6b6a91977bf0865 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 21 Sep 2011 14:43:20 -0700 Subject: intel: Add an AllocTextureImageBuffer() implementation using miptrees. Now we can rely on Mesa core for uploads of data without introducing an extra copy at validate time. --- src/mesa/drivers/dri/intel/intel_tex.c | 43 ++++++++++++++++++++++++++++ src/mesa/drivers/dri/intel/intel_tex.h | 6 ++++ src/mesa/drivers/dri/intel/intel_tex_image.c | 2 +- 3 files changed, 50 insertions(+), 1 deletion(-) (limited to 'src') diff --git a/src/mesa/drivers/dri/intel/intel_tex.c b/src/mesa/drivers/dri/intel/intel_tex.c index bc7b1f64b3e..c7d57f7caf9 100644 --- a/src/mesa/drivers/dri/intel/intel_tex.c +++ b/src/mesa/drivers/dri/intel/intel_tex.c @@ -49,6 +49,48 @@ intelDeleteTextureObject(struct gl_context *ctx, _mesa_delete_texture_object(ctx, texObj); } +static GLboolean +intel_alloc_texture_image_buffer(struct gl_context *ctx, + struct gl_texture_image *image, + gl_format format, GLsizei width, + GLsizei height, GLsizei depth) +{ + struct intel_context *intel = intel_context(ctx); + struct intel_texture_image *intel_image = intel_texture_image(image); + struct gl_texture_object *texobj = image->TexObject; + struct intel_texture_object *intel_texobj = intel_texture_object(texobj); + + if (intel_texobj->mt && + intel_miptree_match_image(intel_texobj->mt, image)) { + intel_miptree_reference(&intel_image->mt, intel_texobj->mt); + DBG("%s: alloc obj %p level %d %dx%dx%d using object's miptree %p\n", + __FUNCTION__, texobj, image->Level, + width, height, depth, intel_texobj->mt); + return true; + } else if (image->Border == 0) { + intel_image->mt = intel_miptree_create_for_teximage(intel, intel_texobj, + intel_image, + false); + + /* Even if the object currently has a mipmap tree associated + * with it, this one is a more likely candidate to represent the + * whole object since our level didn't fit what was there + * before, and any lower levels would fit into our miptree. + */ + intel_miptree_reference(&intel_texobj->mt, intel_image->mt); + + DBG("%s: alloc obj %p level %d %dx%dx%d using new miptree %p\n", + __FUNCTION__, texobj, image->Level, + width, height, depth, intel_image->mt); + return true; + } + + DBG("%s: alloc obj %p level %d %dx%dx%d using swrast\n", + __FUNCTION__, texobj, image->Level, width, height, depth); + + return _swrast_alloc_texture_image_buffer(ctx, image, format, + width, height, depth); +} static void intel_free_texture_image_buffer(struct gl_context * ctx, @@ -182,6 +224,7 @@ intelInitTextureFuncs(struct dd_function_table *functions) functions->NewTextureImage = intelNewTextureImage; functions->DeleteTextureImage = intelDeleteTextureImage; functions->DeleteTexture = intelDeleteTextureObject; + functions->AllocTextureImageBuffer = intel_alloc_texture_image_buffer; functions->FreeTextureImageBuffer = intel_free_texture_image_buffer; functions->MapTextureImage = intel_map_texture_image; functions->UnmapTextureImage = intel_unmap_texture_image; diff --git a/src/mesa/drivers/dri/intel/intel_tex.h b/src/mesa/drivers/dri/intel/intel_tex.h index 895c6348e85..d0757b7d746 100644 --- a/src/mesa/drivers/dri/intel/intel_tex.h +++ b/src/mesa/drivers/dri/intel/intel_tex.h @@ -47,6 +47,12 @@ void intelSetTexBuffer(__DRIcontext *pDRICtx, void intelSetTexBuffer2(__DRIcontext *pDRICtx, GLint target, GLint format, __DRIdrawable *pDraw); +struct intel_mipmap_tree * +intel_miptree_create_for_teximage(struct intel_context *intel, + struct intel_texture_object *intelObj, + struct intel_texture_image *intelImage, + GLboolean expect_accelerated_upload); + GLuint intel_finalize_mipmap_tree(struct intel_context *intel, GLuint unit); void intel_tex_map_level_images(struct intel_context *intel, diff --git a/src/mesa/drivers/dri/intel/intel_tex_image.c b/src/mesa/drivers/dri/intel/intel_tex_image.c index fb91e40a6d6..7c2831e9d22 100644 --- a/src/mesa/drivers/dri/intel/intel_tex_image.c +++ b/src/mesa/drivers/dri/intel/intel_tex_image.c @@ -45,7 +45,7 @@ * 0)..(1x1).
