From f9e6f401e1c3b0a9caeb09f4c14eaea48dd91d06 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 23 Sep 2010 16:19:18 -0700 Subject: [PATCH] unichrome: Mostly revert my convolution removal changes. For this driver, the minimum pitch alignment stuff does appear to be necessary, so leave the separate munged width/height variable in place. --- src/mesa/drivers/dri/unichrome/via_tex.c | 16 +++++++++------- 1 file changed, 9 insertions(+), 7 deletions(-) diff --git a/src/mesa/drivers/dri/unichrome/via_tex.c b/src/mesa/drivers/dri/unichrome/via_tex.c index 01cb3ebbc88..9ae9466c97b 100644 --- a/src/mesa/drivers/dri/unichrome/via_tex.c +++ b/src/mesa/drivers/dri/unichrome/via_tex.c @@ -663,6 +663,8 @@ static void viaTexImage(GLcontext *ctx, struct gl_texture_image *texImage) { struct via_context *vmesa = VIA_CONTEXT(ctx); + GLint postConvWidth = width; + GLint postConvHeight = height; GLint texelBytes, sizeInBytes; struct via_texture_object *viaObj = (struct via_texture_object *)texObj; struct via_texture_image *viaImage = (struct via_texture_image *)texImage; @@ -682,13 +684,13 @@ static void viaTexImage(GLcontext *ctx, texelBytes = _mesa_get_format_bytes(texImage->TexFormat); /* Minimum pitch of 32 bytes */ - if (width * texelBytes < 32) { - width = 32 / texelBytes; - texImage->RowStride = width; + if (postConvWidth * texelBytes < 32) { + postConvWidth = 32 / texelBytes; + texImage->RowStride = postConvWidth; } - assert(texImage->RowStride == width); - viaImage->pitchLog2 = logbase2(width * texelBytes); + assert(texImage->RowStride == postConvWidth); + viaImage->pitchLog2 = logbase2(postConvWidth * texelBytes); /* allocate memory */ if (_mesa_is_format_compressed(texImage->TexFormat)) @@ -697,7 +699,7 @@ static void viaTexImage(GLcontext *ctx, texImage->Height, texImage->Depth); else - sizeInBytes = width * height * texelBytes; + sizeInBytes = postConvWidth * postConvHeight * texelBytes; /* Attempt to allocate texture memory directly, otherwise use main @@ -778,7 +780,7 @@ static void viaTexImage(GLcontext *ctx, dstRowStride = _mesa_format_row_stride(texImage->TexFormat, width); } else { - dstRowStride = width * _mesa_get_format_bytes(texImage->TexFormat); + dstRowStride = postConvWidth * _mesa_get_format_bytes(texImage->TexFormat); } success = _mesa_texstore(ctx, dims, texImage->_BaseFormat, -- 2.30.2
