* nouveau: codegen: LOAD: Take src swizzle into accountHans de Goede2016-04-272-2/+9
| | | | | | | | | | | | | | | | | | | | | | The llvm TGSI backend uses pointers in registers and does things like: LOAD TEMP[0].y, MEMORY[0], TEMP[0] Expecting the data at address TEMP[0].x to get loaded to TEMP[0].y.

* i965/fs: Reduce the response length of sampler messages on Skylake.Kenneth Graunke2016-04-264-5/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Often, we don't need a full 4 channels worth of data from the sampler. For example, depth comparisons and red textures only return one value. To handle this, the sampler message header contains a mask which can be used to disable channels, and reduce the message length (in SIMD16 mode on all hardware, and SIMD8 mode on Broadwell and later). We've never used it before, since it required setting up a message header. This meant trading a smaller response length for a larger message length and additional MOVs to set it up. However, Skylake introduces a terrific new feature: for headerless messages, you can simply reduce the response length, and it makes the implicit header contain an appropriate mask. So to read only RG, you would simply set the message length to 2 or 4 (SIMD8/16). This means we can finally take advantage of this at no cost. total instructions in shared programs: 9091831 -> 9073067 (-0.21%) instructions in affected programs: 191370 -> 172606 (-9.81%) helped: 2609 HURT: 0 total cycles in shared programs: 70868114 -> 68454752 (-3.41%) cycles in affected programs: 35841154 -> 33427792 (-6.73%) helped: 16357 HURT: 8188 total spills in shared programs: 3492 -> 1707 (-51.12%) spills in affected programs: 2749 -> 964 (-64.93%) helped: 74 HURT: 0 total fills in shared programs: 4266 -> 2647 (-37.95%) fills in affected programs: 3029 -> 1410 (-53.45%) helped: 74 HURT: 0 LOST: 1 GAINED: 143 Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | Calling textureOffset() with an offset of <0, 0, 0> is equivalent to calliing texture(). We don't actually need to set up an offset, which causes a message header to be created. A fairly common pattern is to sample at a point with a bunch of offsets, and average them. It's natural to write all the lookups as textureOffset, but use <0, 0> for the center sample. shader-db results on Skylake: total instructions in shared programs: 9092095 -> 9092087 (-0.00%) instructions in affected programs: 2826 -> 2818 (-0.28%) helped: 12 HURT: 2 total cycles in shared programs: 70870166 -> 70870144 (-0.00%) cycles in affected programs: 15924 -> 15902 (-0.14%) helped: 2 HURT: 0 This also helps prevent code quality regressions in a future patch.
