I think you mean to say "non-matching rectangle sizes". Also, as in the previous patch, I'd recommending doing this test at the end of piglit_init() if (!piglit_check_gl_error(GL_NO_ERROR)) { printf("Error setting up fbos\n"); piglit_report_result(PIGLIT_FAIL); } so that if there's an error in setting up the fbo's, it won't cause the test to erroneously pass. With those minor fixes, this patch is: Reviewed-by: Paul Berry <<a href="mailto:stereotype441@gmail.com">stereotype441@gmail.com</a>> </div><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"> --- tests/all.tests | 1 + .../ext_framebuffer_multisample/CMakeLists.gl.txt | 1 + .../blit-mismatched-sizes.cpp | 79 ++++++++++++++++++++ 3 files changed, 81 insertions(+), 0 deletions(-) create mode 100644 tests/spec/ext_framebuffer_multisample/blit-mismatched-sizes.cpp diff --git a/tests/all.tests b/tests/all.tests index 550d330..ee6b22d 100644 --- a/tests/all.tests +++ b/tests/all.tests @@ -1311,6 +1311,7 @@ arb_vertex_program['minmax'] = concurrent_test('arb_vertex_program-minmax') ext_framebuffer_multisample = Group() spec['EXT_framebuffer_multisample'] = ext_framebuffer_multisample ext_framebuffer_multisample['blit-mismatched-samples'] = concurrent_test('ext_framebuffer_multisample-blit-mismatched-samples') +ext_framebuffer_multisample['blit-mismatched-sizes'] = concurrent_test('ext_framebuffer_multisample-blit-mismatched-sizes') ext_framebuffer_multisample['dlist'] = concurrent_test('ext_framebuffer_multisample-dlist') ext_framebuffer_multisample['minmax'] = concurrent_test('ext_framebuffer_multisample-minmax') ext_framebuffer_multisample['negative-copypixels'] = concurrent_test('ext_framebuffer_multisample-negative-copypixels') diff --git a/tests/spec/ext_framebuffer_multisample/CMakeLists.gl.txt b/tests/spec/ext_framebuffer_multisample/CMakeLists.gl.txt index 146b80e..f4efa91 100644 --- a/tests/spec/ext_framebuffer_multisample/CMakeLists.gl.txt +++ b/tests/spec/ext_framebuffer_multisample/CMakeLists.gl.txt @@ -11,6 +11,7 @@ link_libraries ( piglit_add_executable (ext_framebuffer_multisample-accuracy common.cpp accuracy.cpp) piglit_add_executable (ext_framebuffer_multisample-blit-mismatched-samples common.cpp blit-mismatched-samples.cpp) +piglit_add_executable (ext_framebuffer_multisample-blit-mismatched-sizes common.cpp blit-mismatched-sizes.cpp) piglit_add_executable (ext_framebuffer_multisample-dlist dlist.c) piglit_add_executable (ext_framebuffer_multisample-formats common.cpp formats.cpp) piglit_add_executable (ext_framebuffer_multisample-line-smooth common.cpp line-smooth.cpp) diff --git a/tests/spec/ext_framebuffer_multisample/blit-mismatched-sizes.cpp b/tests/spec/ext_framebuffer_multisample/blit-mismatched-sizes.cpp new file mode 100644 index 0000000..4e20bed --- /dev/null +++ b/tests/spec/ext_framebuffer_multisample/blit-mismatched-sizes.cpp @@ -0,0 +1,79 @@ +/* + * Copyright © 2012 Intel Corporation + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
