2014-09-24intel: Fix initial MakeCurrent for drawables of multi screensXiong Zhang1-4/+6
This patch fix a regression caused by commit 11baad35. Multi screens share one context. When the first screen call intel_prepare_render(), it will set ctx->ViewportInitialized to true, so the following screens don't have chance to call intel _prepare_render(). If all screens run following gl command: eglMakeCurrent() glClearColor() glClear() eglSwapBuffers() The first screen can run above command successfully. But the following screen will occur segment fault error on eglSwapBuffers(). Because when following screens run: eglMakeCurrent() won't call intel_prepare_render(); the width and height of Draw buffer is zero, this causes glClear() return early without calling Driver.Clear(); finaly Draw buffer doesn't have bo, so eglSwapBuffers() occur segment fault error.

2014-09-16r300g: set register classes before interferencesConnor Abbott1-2/+4
In commit 567e2769b81863b6dffdac3826a6b729ce6ea37c ("ra: make the p, q test more efficient") I unknowingly introduced a new requirement to the register allocator API: the user must set the register class of all nodes before setting up their interferences, because ra_add_conflict_list() now uses the classes of the two interfering nodes. i965 already did this, but r300g was setting up register classes interleaved with setting up the interference graph. This led to us calculating the wrong q total, and in certain cases e78a01d5e6f77e075fe667a0f0ccb10d89c0dd58 (" ra: optimistically color only one node at a time") made it so that this bug caused a segfault. In particular, the error occurred if the q total was decremented to 1 below 0 for the last node to be pushed onto the stack. Since q_total is an unsigned integer, it overflowed to 0xffffffff, which is what lowest_q_total happens to be initialzed to. This means that we would fail the "new_q_total < lowest_q_total" check on line 476 of register_allocate.c, and so the node would never be pushed onto the stack, which led to segfaults in ra_select() when we failed to ever give it a register.

2014-09-16i965: Mark delta_x/y as BAD_FILE if remapped away completely.Kenneth Graunke2-5/+15
Commit afe3d1556f6b77031f7025309511a0eea2a3e8df (i965: Stop doing remapping of "special" regs.) stopped remapping delta_x/delta_y, and additionally stopped considering them always-live. We later realized delta_x was used in register allocaiton, so we actually needed to remap it, which was fixed in commit 23d782067ae834ad53522b46638ea21c62e94ca3 (i965/fs: Keep track of the register that hold delta_x/delta_y.). However, that commit didn't restore the "always consider it live" part. If all the code using delta_x was eliminated, fs_visitor::delta_x would be left pointing at its old register number. Later code in register allocation would handle that register number specially...even though it wasn't actually delta_x. To combat this, set delta_x/y to BAD_FILE if they're eliminated, and check for that.

2014-09-16i965: Implement GL_PRIMITIVES_GENERATED with non-zero streams.Iago Toral Quiroga1-4/+9
So far we have been using CL_INVOCATION_COUNT to resolve this query but this is no good with streams, as only stream 0 reaches the clipping stage. From ARB_transform_feedback3: "When a generated primitive query for a vertex stream is active, the primitives-generated count is incremented every time a primitive emitted to that stream reaches the Discarding Rasterization stage (see Section 3.x) right before rasterization. This counter is incremented whether or not transform feedback is active." Unfortunately, we don't have any registers that provide the number of primitives written to a specific stream other than the ones that track the number of primitives written to transform feedback in the SOL stage, so we can't implement this exactly as specified. In the past we implemented this feature by activating the SOL unit even if transform feeback was disabled, but making it so that all buffers were disabled and it only recorded statistics, which gave us the right semantics (see 3178d2474ae5bdd1102fb3d76a60d1d63c961ff5). Unfortunately, this came with a significant performance impact and had to be reverted. This new take does not intend to implement the exact semantics required by the spec, but improves what we have now, since now we return the primitive count for stream 0 in all cases. With this patch we use GEN7_SO_PRIM_STORAGE_NEEDED to resolve GL_PRIMITIVES_GENERATED queries for non-zero streams. This would return the number of primitives written to transform feedback for each stream instead. Since non-zero streams are only useful in combination with transform feedback this should not be too bad, and the only case that I think we would not be supporting would be the one in which we want to use both GL_PRIMITIVES_GENERATED and GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN on the same non-zero stream to detect buffer overflow. This patch also fixes the following piglit test: arb_gpu_shader5-xfb-streams-without-invocations This test uses both GL_PRIMITIVES_GENERATED and GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN queries on non-zero streams, but it does never hit the overflow case, so both queries are always expected to return the same value.

2014-09-12glsl: Speed up constant folding for swizzles.Kenneth Graunke1-0/+5
ir_rvalue::constant_expression_value() recursively walks down an IR tree, attempting to reduce it to a single constant value. This is useful when you want to know whether a variable has a constant expression value at all, and if so, what it is. The constant folding optimization pass attempts to replace rvalues with their constant expression value from the bottom up. That way, we can optimize subexpressions, and ideally stop as soon as we find a non-constant subexpression. In order to obtain the actual value of an expression, the optimization pass calls constant_expression_value(). But it should only do so if it knows the value can be combined into a constant. Otherwise, at each step of walking back up the tree, it will walk down the tree again, only to discover what it already knew: it isn't constant. We properly avoided this call for ir_expression nodes, but not for ir_swizzle nodes. This patch fixes that, drastically reducing compile times on certain shaders where tree grafting has given us huge expression trees. It also fixes SuperTuxKart. Thanks to Iago and Mike for help in tracking this down.

2014-09-12i965: Skip allocating UNIFORM file storage for uniforms of size 0.Kenneth Graunke2-6/+6
Samplers take up zero slots and therefore don't exist in the params array, nor are they included in stage_prog_data->nr_params. There's no need to store their size in param_size, as it's only used for dealing with arrays of "real" uniforms (ones uploaded as shader constants). We run into all kinds of problems trying to refer to the uniform storage for variables that don't have uniform storage. For one, we may use some other variable's index, or access out of bounds in arrays. In the FS backend, our extra 2 * MaxSamplerImageUnits params for texture rectangle rescaling paper over a lot of problems. In the VS backend, we claim samplers take up a slot, which also papers over problems. Instead, just skip allocating storage for variables that don't have any.

2014-09-12i965: Disable guardband clipping in the smaller-than-viewport case.Kenneth Graunke1-0/+31
Apparently guardband clipping doesn't work like we thought: objects entirely outside fthe guardband are trivially rejected, regardless of their relation to the viewport. Normally, the guardband is larger than the viewport, so this is not a problem. However, when the viewport is larger than the guardband, this means that we would discard primitives which were wholly outside of the guardband, but still visible. We always program the guardband to 8K x 8K to enforce the restriction that the screenspace bounding box of a single triangle must be no more than 8K x 8K. So, if the viewport is larger than that, we need to disable guardband clipping. Fixes ES3 conformance tests: - framebuffer_blit_functionality_negative_height_blit - framebuffer_blit_functionality_negative_width_blit - framebuffer_blit_functionality_negative_dimensions_blit - framebuffer_blit_functionality_magnifying_blit - framebuffer_blit_functionality_multisampled_to_singlesampled_blit v2: Mention the acronym expansion for TA/TR/MC in the comments.

We always uploaded them together, mostly out of laziness - both required an additional vertex element. However, gl_VertexID now also requires an additional vertex buffer for storing gl_BaseVertex; for non-indirect draws this also means uploading (a small amount of) data. This is extra overhead we don't need if the shader only uses gl_InstanceID. In particular, our clear shaders currently use gl_InstanceID for doing layered clears, but don't need gl_VertexID.

2014-09-12i965: Fix reference counting in new basevertex upload code.Kenneth Graunke1-0/+3
In the non-indirect draw case, we call intel_upload_data to upload gl_BaseVertex. It makes brw->draw.draw_params_bo point to the upload buffer, and increments the upload BO reference count. So, we need to unreference it when making brw->draw.draw_params_bo point at something else, or else we'll retain a reference to stale upload buffers and hold on to them forever. This also means that the indirect case should increment the reference count on the indirect draw buffer when making brw->draw.draw_params_bo point at it. That way, both paths increment the reference count, so we can safely unreference it every time.

2014-09-12i965: Expose gl_BaseVertex via a vertex attribute.Kenneth Graunke3-20/+65
Now that we have the data available, we need to expose it to the shaders. We can reuse the same vertex element that we use for gl_VertexID, but we need to back it by an actual vertex buffer. A hardware restriction requires that vertex attributes coming from a buffer (STORE_SRC) must come before any other types (i.e. STORE_0). So, we have to make gl_BaseVertex be the .x component of the vertex attribute. This means moving gl_VertexID to a different component. I chose to move gl_VertexID and gl_InstanceID to the .z and .w components, respectively, to make room for gl_BaseInstance in the .y component (which would also come from a buffer, and therefore be STORE_SRC).

2014-09-09i965: Handle ir_binop_ubo_load in boolean expression code.Kenneth Graunke2-4/+4
UBO loads can be boolean-valued expressions, too, so we need to handle them in emit_bool_to_cond_code() and emit_if_gen6(). However, unlike most expressions, it doesn't make sense to evaluate their operands, then do something with the results. We just want to evaluate the UBO load as a whole---which performs the read from memory---then load the boolean result into the flag register. Instead of adding code to handle it, we can simply bypass the ir_expression handling, and fall through to the default code, which will do exactly that.

2014-09-08gallivm: Fix Altivec pack intrinsics for little-endianUlrich Weigand1-5/+21
This patch fixes use of Altivec pack intrinsics on little-endian PowerPC systems. Since little-endian operation only affects the load and store instructions, the semantics of pack (and other) instructions that take two input vectors implicitly change: the pack instructions still fill a register placing values from the first operand into the "high" parts of the register, and values from the second operand into the "low" parts of the register, but since vector loads and stores perform an endian swap, the high parts end up at high memory addresses. To still achieve the desired effect, we have to swap the two inputs to the pack instruction on little-endian systems. This is done automatically by the back-end for instructions generated by LLVM, but needs to be done manually when emitting intrisincs (which still result in that instruction being emitted directly).
