| | | | | | | | | | | | When we've changed draw_find_shader_output to return -1 instead of 0 on non found attribs we broke the default behavior of draw, which was to always redirect those to the first (0th) slot. To preserve that behavior if draw_emit_vertex_attr notices a mismatched vertex attrib, it just redirects it to the first slot (instead of trying to use negative index in an array).

* intel: Add multisample scaled blitting in blorp engineAnuj Phogat2013-05-304-74/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | In traditional multisampled framebuffer rendering, color samples must be explicitly resolved via BlitFramebuffer before doing the scaled blitting of the framebuffer. So, scaled blitting of a multisample framebuffer takes two separate calls to BlitFramebuffer. This patch implements the functionality of doing multisampled scaled resolve using just one BlitFramebuffer call. Important changes involved in this patch are listed below: - Use float registers to scale and offset texture coordinates. - Change offset computation to consider float coordinates. - Round the scaled coordinates down to nearest integer. - Modify src texture coordinates clipping to account for scaling.. - Linear filter is not yet implemented in blorp. So, don't use blorp engine to do single sampled scaled blitting. V3: Fix nearest filtering issue in scaled blits. Makes failing piglit fbo-blit-stetch test and framebuffer_blit_functionality_magnifying_blit.test in gles3 CTS pass.

* i965: Fix can_cut_index_handle_restart_index() for byte/short types.Kenneth Graunke2013-05-291-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | Pre-Haswell hardware doesn't support an arbitrary restart index, and instead compares the index buffer value against 0xFF for byte-size buffers, 0xFFFF for short-size buffers, or 0xFFFFFFFF for unsigned integer buffers. OpenGL allows the restart index to be an arbitrary unsigned integer. When comparing against byte/short types, the index buffer value should be promoted to a full 32-bit integer before doing the comparison. The restart index is /not/ supposed to be masked to byte/short size. This means that with certain restart indexes, the comparison should always fail. For example, a restart index of 0xF000FFFF should never match any byte/short index buffer values due to the extra high bits. We must not enable hardware primitive restart in such a case. For now, fall back to software primitive restart as it's the simplest fix. In the future, we could detect restart indexes that will never match and skip both hardware and software primitive restart.

| | | | | | | | | | | | | | | | | | | | | | The code that updates the ctx->Array._RestartIndex derived state mashed it to 0xFFFFFFFF when GL_PRIMITIVE_RESTART_FIXED_INDEX was enabled regardless of the index buffer type. It's supposed to be 0xFF for byte, 0xFFFF for short, or 0xFFFFFFFF for integer types. The new _mesa_primitive_restart_index() helper gets this right. The hardware appears to compare against the full 32-bit value some of the time, causing primitive restart not to occur when it should. The fact that it works some of the time is rather frightening.

| | | | | | | | | | | | | | | | | | The derived state approach currently used (_RestartIndex) doesn't work: in the GL_PRIMITIVE_RESTART_FIXED_INDEX case, the restart index depends on the index buffer's data type, and that isn't known until draw time. The existing code also fails to obey the GL 4.3 rules which say that FIXED_INDEX takes precedence over normal primitive restart.

However, DrawArrays is not supposed to do FixedIndex restart: From the OpenGL 4.3 Core specification, section 10.3.5 (page 302): "If PRIMITIVE_RESTART_FIXED_INDEX is enabled, primitive restart is not performed for array elements transferred by any drawing command not taking a type parameter, including all of the *Draw* commands other than *DrawElements*." The OpenGL ES 3.0 specification agrees by omission: "When DrawElements, DrawElementsInstanced, or DrawRangeElements transfers a set of generic attribute array elements to the GL..."
