From c22a95c4f2db64c61cb25f37acc38254f30850f1 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 30 Dec 2011 08:24:55 -0700 Subject: [PATCH] st/mesa: remove TexSubImage code, use core mesa routines instead. Since the move to Map/UnmapTextureImage, the core mesa routines are equivalent to what the state tracker was doing. The TexImage functions can be replaced too, but there's a few differences that will need to be handled. --- src/mesa/state_tracker/st_cb_texture.c | 143 +------------------------ 1 file changed, 3 insertions(+), 140 deletions(-) diff --git a/src/mesa/state_tracker/st_cb_texture.c b/src/mesa/state_tracker/st_cb_texture.c index 289ad511434..8d30d7acb54 100644 --- a/src/mesa/state_tracker/st_cb_texture.c +++ b/src/mesa/state_tracker/st_cb_texture.c @@ -929,143 +929,6 @@ st_GetTexImage(struct gl_context * ctx, } -static void -st_TexSubimage(struct gl_context *ctx, GLint dims, GLenum target, GLint level, - GLint xoffset, GLint yoffset, GLint zoffset, - GLint width, GLint height, GLint depth, - GLenum format, GLenum type, const void *pixels, - const struct gl_pixelstore_attrib *packing, - struct gl_texture_object *texObj, - struct gl_texture_image *texImage) -{ - struct st_context *st = st_context(ctx); - struct st_texture_image *stImage = st_texture_image(texImage); - GLuint dstRowStride; - const GLuint srcImageStride = - _mesa_image_image_stride(packing, width, height, format, type); - GLint i; - const GLubyte *src; - /* init to silence warning only: */ - enum pipe_transfer_usage transfer_usage = PIPE_TRANSFER_WRITE; - GLubyte *dstMap; - - DBG("%s target %s level %d offset %d,%d %dx%d\n", __FUNCTION__, - _mesa_lookup_enum_by_nr(target), - level, xoffset, yoffset, width, height); - - pixels = - _mesa_validate_pbo_teximage(ctx, dims, width, height, depth, format, - type, pixels, packing, "glTexSubImage2D"); - if (!pixels) - return; - - /* for a 1D array upload the image as a series of layer with height = 1 */ - if (target == GL_TEXTURE_1D_ARRAY) { - depth = height; - height = 1; - } - - /* Map buffer if necessary.
