* mesa/st: add per sample shading state to fp key and set interpolationIlia Mirkin2014-07-093-1/+11
| | | | | | | | | | | This enables a gallium driver not to care about the semantics of ARB_sample_shading vs ARB_gpu_shader5 sample attributes. When ARB_sample_shading-style sample shading is enabled, all of the fp inputs are marked for interpolation at the sample location.

* gallium: switch dedicated centroid field to interpolation locationIlia Mirkin2014-07-093-7/+13
| | | | | | | | The new location field can be either center, centroid, or sample, which indicates the location that the shader should interpolate at. Signed-off-by: Ilia Mirkin <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]>
* meta: Call glObjectLabel before linking.Kenneth Graunke2014-07-091-1/+1
| | | | | | | | | | | i965 precompiles shaders at link time, and prints a disassembly if INTEL_DEBUG=vs,gs,fs, including the shader name. However, blit shaders were showing up as "unnamed" since we hadn't set a name prior to linking.

* ff_fragment_shader: Access glsl_types directly.Kenneth Graunke2014-07-091-15/+15
| | | | | | | | | Originally, we didn't have direct accessors for all of the GLSL types, so the only way to get at them was to use the symbol table. Now, we can just get at them directly, which is simpler and faster. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ben Widawsky <[email protected]>

* i965/fs: Track dependencies in instruction scheduling per reg offset.Matt Turner2014-07-081-8/+15
| | | | | | | | | | | | | | | | | | | | | Previously instruction scheduling tracked dependencies on a per-register basis. This meant that there was an artificial dependency between interpolation instructions writing into the same virtual register. Instruction scheduling would insert a number of instructions between the two instructions in this example, when they are actually independent. linterp vgrf8+0.0:F, hw_reg2:F, hw_reg3:F, hw_reg6:F linterp vgrf8+1.0:F, hw_reg2:F, hw_reg3:F, hw_reg6+16:F This lead to cases where the first texture coordinate is interpolated at the beginning of the shader, but the second is done immediately before the texture operation that uses it as a source. After this change, the artificial dependency is removed and the interpolation instructions are scheduled together. Reviewed-by: Kenneth Graunke <[email protected]>
* i965: Extend compute-to-mrf pass to understand blocks of MOVsKristian Høgsberg2014-07-071-10/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current compute-to-mrf pass doesn't handle blocks of MOVs. Shaders that end with a texture fetch follwed by an fb write are left like this: 0x00000000: pln(8) g6<1>F g4<0,1,0>F g2<8,8,1>F { align1 WE_normal 1Q compacted }; 0x00000008: pln(8) g7<1>F g4.4<0,1,0>F g2<8,8,1>F { align1 WE_normal 1Q compacted }; 0x00000010: send(8) g2<1>UW g6<8,8,1>F sampler (1, 0, 0, 1) mlen 2 rlen 4 { align1 WE_normal 1Q }; 0x00000020: mov(8) g113<1>F g2<8,8,1>F { align1 WE_normal 1Q compacted }; 0x00000028: mov(8) g114<1>F g3<8,8,1>F { align1 WE_normal 1Q compacted }; 0x00000030: mov(8) g115<1>F g4<8,8,1>F { align1 WE_normal 1Q compacted }; 0x00000038: mov(8) g116<1>F g5<8,8,1>F { align1 WE_normal 1Q compacted }; 0x00000040: sendc(8) null g113<8,8,1>F render ( RT write, 0, 4, 12) mlen 4 rlen 0 { align1 WE_normal 1Q EOT }; This patch lets compute-to-mrf recognize blocks of MOVs and match them to instructions (typically SEND) that writes multiple registers. With this, the above shader becomes: 0x00000000: pln(8) g6<1>F g4<0,1,0>F g2<8,8,1>F { align1 WE_normal 1Q compacted }; 0x00000008: pln(8) g7<1>F g4.4<0,1,0>F g2<8,8,1>F { align1 WE_normal 1Q compacted }; 0x00000010: send(8) g113<1>UW g6<8,8,1>F sampler (1, 0, 0, 1) mlen 2 rlen 4 { align1 WE_normal 1Q }; 0x00000020: sendc(8) null g113<8,8,1>F render ( RT write, 0, 20, 12) mlen 4 rlen 0 { align1 WE_normal 1Q EOT }; which is the bulk of the shader db results: total instructions in shared programs: 987040 -> 986720 (-0.03%) instructions in affected programs: 844 -> 524 (-37.91%) GAINED: 0 LOST: 0 The optimization also applies to MRT shaders that write the same color value to multiple RTs, in which case we can eliminate four MOVs in a similar fashion. See fbo-drawbuffers2-blend in piglit for an example. No measurable performance impact. No piglit regressions. Signed-off-by: Kristian Høgsberg <[email protected]>
