* glsl: clean up and fix bug in varying linking rulesTimothy Arceri2016-02-091-74/+63
| | | | | | | | | | | | | | | | The existing code was very hard to follow and has been the source of at least 3 bugs in the past year. The existing code also has a bug for SSO where if we have a multi-stage SSO for example a tes -> gs program, if we try to use transform feedback with gs the existing code would look for the transform feedback varyings in the tes stage and fail as it can't find them. V2: Add more code comments, always try to remove unused inputs to the first stage. Reviewed-by: Kenneth Graunke <[email protected]>
* glsl: simplify ES Vertex/Fragment shader requirementsTimothy Arceri2016-02-091-28/+28
| | | | | | | | | | | | We really just needed to skip the existing ES < 3.1 check if we have a compute shader, all other scenarios are already covered. * No shaders is a link error. * Geom or Tess without Vertex is a link error which means we always require a Vertex shader and hence a Fragment shader. * Finally a Compute shader linked with any other stage is a link error.

* glsl: don't attempt to link empty programTimothy Arceri2016-02-091-23/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously an empty program would go through the entire link_shaders() function and we would have to be careful not to cause a segfault. In core profile also now set link_status to false by generating an error, it was previously set to true. From Section 7.3 (PROGRAM OBJECTS) of the OpenGL 4.5 spec: "Linking can fail for a variety of reasons as specified in the OpenGL Shading Language Specification, as well as any of the following reasons: - No shader objects are attached to program." V2: Only generate an error in core profile and add spec quote (Ian) V3: generate error in ES too, remove previous check which was only applying the rule to GL 4.5/ES 3.1 and above. My understand is that this spec change is clarifying previously undefined behaviour and therefore should be applied retrospectively. The ES CTS tests for this are in ES 2 I suspect it was passing because it would have generated an error for not having both a vertex and fragment shader.

* nir: Recognize open-coded bitfield_reverse.Matt Turner2016-02-081-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | Helps 11 shaders in UnrealEngine4 demos. I seriously hope they would have given us bitfieldReverse() if we exposed GL 4.0 (but we do expose ARB_gpu_shader5, so why not use that anyway?). instructions in affected programs: 4875 -> 4633 (-4.96%) cycles in affected programs: 270516 -> 244516 (-9.61%) I suspect there's a *lot* of room to improve nir_search/opt_algebraic's handling of this. We'd actually like to match, e.g., step2 by matching step1 once and then doing a pointer comparison for the second instance of step1, but unfortunately we generate an enormous tuple for instead. The .text size increases by 6.5% and the .data by 17.5%. text data bss dec hex filename 22957 45224 0 68181 10a55 nir_libnir_la-nir_opt_algebraic.o 24461 53160 0 77621 12f35 nir_libnir_la-nir_opt_algebraic.o I'd be happy to remove this if Unreal4 uses bitfieldReverse() if it is in a GL 4.0 context once we expose GL 4.0.

* nir: Handle large unsigned values in opt_algebraic.Matt Turner2016-02-081-4/+1
| | | | | | | | | | | | | | | The next patch adds an algebraic rule that uses the constant 0xff00ff00. Without this change, the build fails with return hex(struct.unpack('I', struct.pack('i', self.value))[0]) struct.error: 'i' format requires -2147483648 <= number <= 2147483647 The hex() function handles integers of any size, and assigning a negative value to an unsigned does what we want in C.

* nir: Do opt_algebraic in reverse order.Matt Turner2016-02-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | Walking the SSA definitions in order means that we consider the smallest algebraic optimizations before larger optimizations. So if a smaller rule is part of a larger rule, the smaller one will happen first, preventing the larger one from happening. instructions in affected programs: 32721 -> 32611 (-0.34%) helped: 106 In programs whose nir_optimize loop count changes (129 of them): before: 1164 optimization loops after: 1071 optimization loops Of the 129 affected, 16 programs' optimization loop counts increased.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are never render target reads, so there are no scheduling hazards. Giving the extra flexibility to the scheduler makes it possible to do FB writes as soon as their sources are available, reducing register pressure. It also makes it possible to do the payload setup for more than one FB write message at a time, which could better hide latency. shader-db results on Skylake: total instructions in shared programs: 9110254 -> 9110211 (-0.00%) instructions in affected programs: 2898 -> 2855 (-1.48%) helped: 3 HURT: 0 LOST: 0 GAINED: 1 A reduction in instruction counts is surprising, but legitimate: the three shaders helped were spilling, and reducing register pressure allowed us to issue fewer spills/fills. total cycles in shared programs: 69035108 -> 68928820 (-0.15%) cycles in affected programs: 4412402 -> 4306114 (-2.41%) helped: 4457 HURT: 213 Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Matt Turner <[email protected]> Reviewed-by: Connor Abbott <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The state tracker never handled this properly, and it finally annoyed me for the second time so I decided to fix it properly. This is inspired by the NIR sampler lowering code and I only realised NIR seems to do its deref ordering different to GLSL at the last minute, once I got that things got much easier. it fixes a bunch of tests in tests/spec/arb_gpu_shader5/execution/sampler_array_indexing/ v2: fix AoA tests when forced on. I was right I didn't need all that code, fixing the AoA code meant cleaning up a chunk of code I didn't like in the array handling. v3: start generalising the code a bit more for atomics. v3.1: use UniformRemapTable v4: handle uniforms differently using the param_index, and go back to UniformStorage fix issues identified by Timothy with deref handling. v4.1: squash const fix and move handling 1D const out of recursive function.

This wasn't part of my original L3 partitioning code because I was able to reproduce hangs on Gen7 hardware when the state cache invalidation happened asynchronously with previous 3D rendering, which should no longer be possible after the previous change.

* i965: Fix cache pollution race during L3 partitioning set-up.Francisco Jerez2016-02-081-8/+23
| | | | | | | | | | | | | | | | We need to split the stalling flush from the RO cache invalidation into a different PIPE_CONTROL command to make sure that the top of the pipe invalidation happens after any previous rendering is complete. Otherwise it's possible for previous rendering to pollute the L3 cache in the short window of time between RO invalidation and the completion of the stalling flush.

| | | | | | | | | | | | | | | | | | | | | | | | | The vec4 backend, at the end, does this: if (inst->is_3src()) { for (int i = 0; i < 3; i++) { if (inst->src[i].vstride == BRW_VERTICAL_STRIDE_0) assert(brw_is_single_value_swizzle(inst->src[i].swizzle)); So make sure that we use the same conditions when trying to copy-propagate. UNIFORMs will be converted to vstride 0 in convert_to_hw_regs, but so will ATTRs when interleaved (as will happen in a GS with multiple attributes). Since the vstride is not set at copy-prop time, infer it by inspecting dispatch_mode and reject ATTRs if they have non-scalar swizzles and are interleaved.
