OpenGL ES spec states: "For normalized fixed-point rendering surfaces, the combination format RGBA and type UNSIGNED_BYTE is accepted."
This fixes following failing VK-GL-CTS tests: KHR-GLES3.packed_pixels.pbo_rectangle.rgba8_snorm KHR-GLES3.packed_pixels.rectangle.rgba8_snorm KHR-GLES3.packed_pixels.varied_rectangle.rgba8_snorm Signed-off-by: Tapani Pälli <tapani.pa...@intel.com> https://bugs.freedesktop.org/show_bug.cgi?id=107658 Cc: mesa-sta...@lists.freedesktop.org --- This is a partial fix to the bug. I believe there are 2 separate issues within reported bug and this fixes the first one. src/mesa/main/readpix.c | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/src/mesa/main/readpix.c b/src/mesa/main/readpix.c index 2cbb578a37f..556c860d393 100644 --- a/src/mesa/main/readpix.c +++ b/src/mesa/main/readpix.c @@ -958,6 +958,15 @@ read_pixels_es3_error_check(struct gl_context *ctx, GLenum format, GLenum type, return GL_NO_ERROR; } } + if (type == GL_UNSIGNED_BYTE) { + switch (internalFormat) { + case GL_R8_SNORM: + case GL_RG8_SNORM: + case GL_RGBA8_SNORM: + if (_mesa_has_EXT_render_snorm(ctx)) + return GL_NO_ERROR; + } + } break; case GL_BGRA: /* GL_EXT_read_format_bgra */ -- 2.14.4 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
