From b4a70401f52e5d7e08c94715b250ea1de8f63d15 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 1 Sep 2015 15:44:46 +1000 Subject: [PATCH] texcompress_s3tc/fxt1: fix stride checks (v1.1) The fastpath currently checks the RowLength != width, but if you have a RowLength of 7, and Alignment of 4, then that shouldn't match. align the rowlength to the pack alignment before comparing. This fixes compressed cases in CTS packed_pixels_pixelstore test when SKIP_PIXELS is enabled, which causes row length to get set. v1.1: add fxt1 fix (Iago) Cc: "11.0" Reviewed-by: Iago Toral Quiroga Signed-off-by: Dave Airlie --- src/mesa/main/texcompress_fxt1.c | 2 +- src/mesa/main/texcompress_s3tc.c | 8 ++++---- 2 files changed, 5 insertions(+), 5 deletions(-) diff --git a/src/mesa/main/texcompress_fxt1.c b/src/mesa/main/texcompress_fxt1.c index f06f048820d..d605e255962 100644 --- a/src/mesa/main/texcompress_fxt1.c +++ b/src/mesa/main/texcompress_fxt1.c @@ -65,7 +65,7 @@ _mesa_texstore_rgb_fxt1(TEXSTORE_PARAMS) if (srcFormat != GL_RGB || srcType != GL_UNSIGNED_BYTE || ctx->_ImageTransferState || - srcPacking->RowLength != srcWidth || + ALIGN(srcPacking->RowLength, srcPacking->Alignment) != srcWidth || srcPacking->SwapBytes) { /* convert image to RGB/GLubyte */ GLubyte *tempImageSlices[1]; diff --git a/src/mesa/main/texcompress_s3tc.c b/src/mesa/main/texcompress_s3tc.c index 7ce3cb88ec7..6cfe06a9910 100644 --- a/src/mesa/main/texcompress_s3tc.c +++ b/src/mesa/main/texcompress_s3tc.c @@ -130,7 +130,7 @@ _mesa_texstore_rgb_dxt1(TEXSTORE_PARAMS) if (srcFormat != GL_RGB || srcType != GL_UNSIGNED_BYTE || ctx->_ImageTransferState || - srcPacking->RowLength != srcWidth || + ALIGN(srcPacking->RowLength, srcPacking->Alignment) != srcWidth || srcPacking->SwapBytes) { /* convert image to RGB/GLubyte */ GLubyte *tempImageSlices[1]; @@ -187,7 +187,7 @@ _mesa_texstore_rgba_dxt1(TEXSTORE_PARAMS) if (srcFormat != GL_RGBA || srcType != GL_UNSIGNED_BYTE || ctx->_ImageTransferState || - srcPacking->RowLength != srcWidth || + ALIGN(srcPacking->RowLength, srcPacking->Alignment) != srcWidth || srcPacking->SwapBytes) { /* convert image to RGBA/GLubyte */ GLubyte *tempImageSlices[1]; @@ -244,7 +244,7 @@ _mesa_texstore_rgba_dxt3(TEXSTORE_PARAMS) if (srcFormat != GL_RGBA || srcType != GL_UNSIGNED_BYTE || ctx->_ImageTransferState || - srcPacking->RowLength != srcWidth || + ALIGN(srcPacking->RowLength, srcPacking->Alignment) != srcWidth || srcPacking->SwapBytes) { /* convert image to RGBA/GLubyte */ GLubyte *tempImageSlices[1]; @@ -300,7 +300,7 @@ _mesa_texstore_rgba_dxt5(TEXSTORE_PARAMS) if (srcFormat != GL_RGBA || srcType != GL_UNSIGNED_BYTE || ctx->_ImageTransferState || - srcPacking->RowLength != srcWidth || + ALIGN(srcPacking->RowLength, srcPacking->Alignment) != srcWidth || srcPacking->SwapBytes) { /* convert image to RGBA/GLubyte */ GLubyte *tempImageSlices[1]; -- 2.30.2
