| | | | | | | | | | In the Vulkan driver we use a single flat input instead of a uniform because setting up push constants is more disruptive to the pipeline than setting up another vertex input.

* i965/fs: Allow spilling for SIMD16 compute shadersJordan Justen2016-03-081-1/+1
| | | | | | | | | | | | | | | | For fragment shaders, we can always use a SIMD8 program. Therefore, if we detect spilling with a SIMD16 program, then it is better to skip generating a SIMD16 program to only rely on a SIMD8 program. Unfortunately, this doesn't work for compute shaders. For a compute shader, we may be required to use SIMD16 if the local workgroup size is bigger than a certain size. For example, on gen7, if the local workgroup size is larger than 512, then a SIMD16 program is required.

Otherwise, they're very straightforward. This patch implements SIMD8 tessellation evaluation shaders for Gen8+. The tessellator can generate a lot of geometry, so operating in SIMD8 mode (8 vertices per thread) is more efficient than SIMD4x2 mode (only 2 vertices per thread).

* i965: Add src/dst interference for certain instructions with hazards.Kenneth Graunke2015-11-301-0/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When working on tessellation shaders, I created some vec4 virtual opcodes for creating message headers through a sequence like: mov(8) g7<1>UD 0x00000000UD { align1 WE_all 1Q compacted }; mov(1) g7.5<1>UD 0x00000100UD { align1 WE_all }; mov(1) g7<1>UD g0<0,1,0>UD { align1 WE_all compacted }; mov(1) g7.3<1>UD g8<0,1,0>UD { align1 WE_all }; This is done in the generator since the vec4 backend can't handle align1 regioning. From the visitor's point of view, this is a single opcode: hs_set_output_urb_offsets vgrf7.0:UD, 1U, vgrf8.xxxx:UD Normally, there's no hazard between sources and destinations - an instruction (naturally) reads its sources, then writes the result to the destination. However, when the virtual instruction generates multiple hardware instructions, we can get into trouble. In the above example, if the register allocator assigned vgrf7 and vgrf8 to the same hardware register, then we'd clobber the source with 0 in the first instruction, and read back the wrong value in the last one. It occured to me that this is exactly the same problem we have with SIMD16 instructions that use W/UW or B/UB types with 0 stride. The hardware implicitly decodes them as two SIMD8 instructions, and with the overlapping regions, the first would clobber the second. Previously, we handled that by incrementing the live range end IP by 1, which works, but is excessive: the next instruction doesn't actually care about that. It might also be the end of control flow. This might keep values alive too long. What we really want is to say "my source and destinations interfere". This patch creates new infrastructure for doing just that, and teaches the register allocator to add interference when there's a hazard. For my vec4 case, we can determine this by switching on opcodes. For the SIMD16 case, we just move the existing code there. I audited our existing virtual opcodes that generate multiple instructions; I believe FS_OPCODE_PACK_HALF_2x16_SPLIT needs this treatment as well, but no others. v2: Rebased by mattst88.

* i965: Fix fragment shader struct inputs.Kenneth Graunke2015-11-251-78/+79
| | | | | | | | | | | | | | | | | | | | | | | | | Apparently we have literally no support for FS varying struct inputs. This is somewhat surprising, given that we've had tests for that very feature that have been passing for a long time. Normally, varying packing splits up structures for us, so we don't see them in the backend. However, with SSO, varying packing isn't around to save us, and we get actual structs that we have to handle. This patch changes fs_visitor::emit_general_interpolation() to work recursively, properly handling nested structs/arrays/and so on. (It's easier to read with diff -b, as indentation changes.) When using the vec4 VS backend, this fixes rendering in an upcoming game from Feral Interactive. (The scalar VS backend requires additional bug fixes in the next patch.) v2: Use pointers instead of pass-by-mutable-reference (Jason, Matt).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The geometry and tessellation control shader stages both read from multiple URB entries (one per vertex). The thread payload contains several URB handles which reference these separate memory segments. In GLSL, these inputs are represented as per-vertex arrays; the outermost array index selects which vertex's inputs to read. This array index does not necessarily need to be constant. To handle that, we need to use indirect addressing on GRFs to select which of the thread payload registers has the appropriate URB handle. (This is before we can even think about applying the pull model!) This patch introduces a new opcode which performs a MOV from a source using VxH indirect addressing (which allows each of the 8 SIMD channels to select distinct data.)
