* i965: Unroll SIMD16 DDY_FINE on Sandybridge.Kenneth Graunke2016-04-251-1/+5
| | | | | | | | | | | | This fixes 10 dEQP-GLES3 subtests: dEQP-GLES3.functional.shaders.derivate.dfdy.texture.float_nicest.*. Matt noticed that our Piglit tests for this use even numbered registers, while the failing dEQP tests use odd numbered registers. We believe that it works for even numbered registers, but not otherwise. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Matt Turner <[email protected]>

| | | | | | | | | | | | | | | | If the bound framebuffer has a format of MESA_FORMAT_R_UNORM, then IMPLEMENTATION_COLOR_READ_FORMAT will return GL_RED.

* i965: Introduce state flag for blorpTopi Pohjolainen2016-04-232-0/+3
| | | | | | | | | | | | | | | | | | | | | | | In the past, BLORP has clobbered all BRW_NEW_* state flags, to trigger re-emission of the entire 3D pipeline on the next draw. However, there are some packets BLORP simply leaves alone, so there's no need to re-emit them. Trying to reduce the set of dirty bits flagged after BLORP runs is tricky. Instead, we introduce a BRW_NEW_BLORP flag. This should be set on any atom which emits a packet that BLORP also emits. When BLORP runs, it will flag BRW_NEW_BLORP, causing those packets to get re-emitted. This also makes it easy to avoid re-emitting specific atoms - we can simply drop the BRW_NEW_BLORP flag on those. To start, we assume that all packets need to be re-emitted. This is the safest approach and closest to the existing code's behavior. Many of these are obviously not required, and can be dropped in subsequent patches. Signed-off-by: Topi Pohjolainen <[email protected]> Signed-off-by: Kenneth Graunke <[email protected]>

| | | | | | | | | | | | | | | | Starting with Skylake, the display engine is capable of scanning out from Y-tiled buffers. As such, we can and should use Y-tiling for better efficiency. This also has the added benefit of being able to fast clear the winsys buffer. Note that the buffer allocation done for mipmaps will already never allocate an X-tiled buffer for GEN9. This has an almost universal positive impact on benchmarks, some improving by as much as 20%.

* i965: Fix clear code for ignoring colormask for XRGB formats on Gen9+.Kenneth Graunke2016-04-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | In commit cda886a4851ab767fba40e8474d6fa8190347e4f, Neil made us stop advertising RGBX formats on Gen9+, as the hardware apparently no longer has working fast clear support for those formats. Instead, we just fall back to RGBA formats, and use SCS to override alpha to 1.0. This is fine, but had one unintended side effect: it made us fall back to slow clears when the color mask disables alpha. Normally, we ignore the color mask for non-existent channels. This includes alpha for XRGB formats as writing garbage to the X channel is harmless. But, now that we use RGBA, we think there's a real alpha channel, and can't do the optimization. To hack around this, check if _BaseFormat is GL_RGB and ignore alpha. Improves WebGL Aquarium performance on Skylake GT3e by about 50% by letting it use repclears instead of slow clears.

* i965/blorp: Improve precission of blitting coordinates when clippingIago Toral Quiroga2016-04-211-61/+163
| | | | | | | | | | | | | | | | | | | | | | | | | | | We do this in two steps: first we clip the dst rect and adjust the src rect accordingly. Then we do it the other way around. In both passes the adjustment part involves multiplying by a scale factor that can lead to a small precision loss. This is breaking a few dEQP tests. Specifically, the problem happens when we need to clip the same coordinate twice. For example, if srcX0 and dstX0 need both to be clipped we want to avoid the situation where we clip srcX0 first, then adjust dstX0 accordingly but then we realize that the resulting dstX0 still needs to be clipped, so we clip dstX0 and adjust srcX0 again. Each of these two passes can lead to precission loss. What we want to do here is detect the rect that leads to the largest clip (accounting for the scale factor involved), clip that rect and adjust the other one. With this we ensure that the adjusted coordinate does not need to be clipped again and we can skip a second pass, improving precision.
