* vc4: Initialize pack field of qreg to 0 in qir_get_tempBoyan Ding2015-09-041-0/+1
| | | | | | | | | | | | | This avoids generation of undefined packing in qir and qpu instructions, fixing a lot of rendering errors.

* i965: Disallow PixelTransfer operations for tiled-memcpy TexImage/ReadPixelsChris Wilson2015-09-042-0/+8
| | | | | | | | | | | | | | | The tiled memcpy fast paths perform a simple blit (with only a couple of trivial pixel conversion routines) and do not accommodate PixelTransfer operations. Therefore if any are set, fallback to the regular routines. Note that PixelTransfer only applies to TexImage and ReadPixels, not to GetTexImage.

* i965/vec4: Don't unspill the same register in consecutive instructionsIago Toral Quiroga2015-09-041-8/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we have spilled/unspilled a register in the current instruction, avoid emitting unspills for the same register in the same instruction or consecutive instructions following the current one as long as they keep reading the spilled register. This should allow us to avoid emitting costy unspills that come with little benefit to register allocation. v2: - Apply the same logic when evaluating spilling costs (Curro). v3: - Abstract the logic that decides if a register can be reused in a function. that can be used from both spill_reg and evaluate_spill_costs (Curro). v4: - Do not disallow reusing scratch_reg in predicated reads (Curro). - Track if previous sources in the same instruction read scratch_reg (Curro). - Return prev_inst_read_scratch_reg at the end (Curro). - No need to explicitily skip scratch read/write opcodes in spill_reg (Curro). - Fix the comments explaining what happens when we hit an instruction that does not read or write scratch_reg (Curro) - Return true early when the current or previous instructions read scratch_reg with a compatible mask. v5: - Do not return true early, the loop should not be expensive anyway and this adds more complexity (Curro).

* i965: Don't do legacy userclipping in non-compatibility contexts.Kenneth Graunke2015-09-031-0/+1
| | | | | | | | | | | | | | | | | According to the GLSL 1.50 specification, page 76: "The shader must also set all values in gl_ClipDistance that have been enabled via the OpenGL API, or results are undefined." With this patch, we only enable clip distance writes when the shader actually writes them. We no longer force a value to be written when clip planes are enabled in the API. This could mean the first varying slot would be used as clip distances - I believe it should be the safe kind of undefined behavior. Empirically, it doesn't seem to cause a problem.

| | | | | | | | | The legacy userclip fields are only used for the vertex shader, and at that point there's only program_string_id and the tex struct, which are common to all keys.

* i965: Delete the brw_vue_program_key::userclip_active flag.Kenneth Graunke2015-09-035-22/+15
| | | | | | | | | | | | | | | | | There are two uses of this flag. The primary use is checking whether we need to emit code to convert legacy gl_ClipVertex/gl_Position clipping to clip distances. In this case, we also have to upload the clip planes as uniforms, which means setting nr_userclip_plane_consts to a positive value. Checking if it's > 0 works for detecting this case. Gen4-5 also wants to know whether we're doing clipping at all, so it can emit user clip flags. Checking if output_reg[VARYING_SLOT_CLIP_DIST0] is set to a real register suffices for this.

* i965: Remove legacy clip plane handling from geometry shaders.Kenneth Graunke2015-09-033-33/+8
| | | | | | | | | | | | | | | | | | We only support geometry shaders in core profiles, where gl_ClipVertex doesn't exist. Presumably the even older behavior of clipping to gl_Position isn't supported either. In fact, GLSL 1.50 page 76 claims: "The shader must also set all values in gl_ClipDistance that have been enabled via the OpenGL API, or results are undefined." So we don't need to handle legacy clipping in geometry shaders. I think Paul added this back when we were considering supporting the old GL_ARB_geometry_shader4 extension.

| | | | | | | | | | | | | | | | | | | | | | commit 472ef9a02f2e5c5d0caa2809cb736a0f4f0d4693 introduced code to change the types of SEL and MOV instructions for moves that simply "copy bits around". It didn't account for type conversion moves, however. So it would happily turn this: mov(8) vgrf6:D, -vgrf5:D mov(8) vgrf7:F, vgrf6:UD into this: mov(8) vgrf6:D, -vgrf5:D mov(8) vgrf7:D, -vgrf5:D which erroneously drops the conversion to float.

* i965/gen9: Annotate input coverage mask changeBen Widawsky2015-09-032-2/+22
| | | | | | | | | | | | | | | | | | | | | | | | | As far as I can tell, the behavior is preserved from the previous generations. Before we set a single bit to tell the FS whether or not we'll be using an input coverage mask. Now we have some options which are implementing various extensions. These bits are used for the various conservative rasterization mechanisms (for collision detection, binning, and whatever else). I believe that the behavior is preserved because the problem which conservative rasterization is attempting to fix would go away with the "NORMAL" mode (at the cost of performance, I believe). This patch serves as documentation of the change by creating the enums, as well as giving some of the history with the links here so that the next person who comes along and looks at it doesn't spend as long as I had to in order to determine if there is an issue or not. Previously, this algorithm had been done in software, and this can still be used as long as we don't export an extension stating otherwise.

* glsl: Handle attribute aliasing in attribute storage limit check.Kenneth Graunke2015-09-021-28/+36
| | | | | | | | | | | | | | | | | | | | | | | | | In various versions of OpenGL and GLSL, it's possible to declare multiple VS input variables with aliasing attribute locations. So, when computing the storage requirements for vertex attributes, we can't simply add up the sizes. Instead, we need to look at the enabled slots. This patch begins tracking which attributes are double types that are larger than 128-bits (i.e. take up two vec4 slots). We then count normal attributes once, and count the double-size attributes a second time. Fixes deQP functional.attribute_location.bind_aliasing.max_cond_* tests on i965, which regressed with commit ad208d975a6d3aebe14f7c2c16039ee20.
