| | | | | | | | | | | | | | This reverts commit d0e1d6b7e27bf5f05436e47080d326d7daa63af2. The change in the vec4 code is a mistake -- there's never an FS_OPCODE_FB_WRITE in vec4 code. The change in the fs code had the (harmless) effect of not recognizing an FB_WRITE as a scheduling barrier even if it was marked EOT -- harmless because the scheduler marked the last instruction of a block as a barrier, something I'm changing in the following patches. This will be reimplemented later in the series.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Yuanhan Liu decided these were useful for linear filtering in commit 76669381 (circa 2011). Prior to that, we never set them; it seems he tried to preserve that behavior for nearest filtering.

* i965: Always use BRW_TEXCOORDMODE_CUBE when seamless filtering.Kenneth Graunke2016-03-281-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | When using seamless cube map mode and NEAREST filtering, we explicitly overrode the wrap modes to CLAMP_TO_EDGE. This was to implement the following spec text: "If NEAREST filtering is done within a miplevel, always apply apply wrap mode CLAMP_TO_EDGE." However, textureGather() ignores the sampler's filtering mode, and instead returns the four pixels that would be blended by LINEAR filtering. This implies that we should do proper seamless filtering, and include pixels from adjacent cube faces. It turns out that we can simply delete the NEAREST -> CLAMP_TO_EDGE overrides. Normal cube map sampling works by first selecting the face, and then nearest filtering fetches the closest texel. If the nearest texel was on a different face, then that face would have been chosen. So it should always be within the face anyway, which effectively performs CLAMP_TO_EDGE. Fixes 86 dEQP-GLES31.texture.gather.basic.cube.* tests.

* i965: Fix brw_render_cache_set_check_flush's PIPE_CONTROLs.Kenneth Graunke2016-03-282-3/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our driver uses the brw_render_cache mechanism to track buffers we've rendered to and are about to sample from. Previously, we did a single PIPE_CONTROL with the following bits set: - Render Target Flush - Depth Cache Flush - Texture Cache Invalidate - VF Cache Invalidate - Instruction Cache Invalidate - CS Stall This combined both "top of pipe" invalidations and "bottom of pipe" flushes, which isn't how the hardware is intended to be programmed. The "top of pipe" invalidations may happen right away, without any guarantees that rendering using those caches has completed. That rendering may continue altering the caches. The "bottom of pipe" flushes do wait for the rendering to complete. The CS stall also prevents further work from happening until data is flushed out. What we wanted to do was wait for rendering complete, flush the new data out of the render and depth caches, wait, then invalidate any stale data in read-only caches. We can accomplish this by doing the "bottom of pipe" flushes with a CS stall, then the "top of pipe" flushes as a second PIPE_CONTROL. The flushes will wait until the rendering is complete, and the CS stall will prevent the second PIPE_CONTROL with the invalidations from executing until the first is done. Fixes dEQP-GLES3.functional.texture.specification.teximage2d_pbo subtests on Braswell and Skylake. These tests hit the meta PBO texture upload path, which binds the PBO as a texture and samples from it, while rendering to the destination texture. The tests then sample from the texture. For now, we leave Gen4-5 alone. It probably needs work too, but apparently it hasn't even been setting the (G45+) TC invalidation bit at all... v2: Add Sandybridge post-sync non-zero workaround, for safety.

It uses occlusion queries to inspect whether pixels are rendered or not. Unfortunately, the hardware is not dispatching any pixel shaders, so discards never happen, and the full quad of pixels increments PS_DEPTH_COUNT, making the occlusion query results bogus. To understand why, we have to delve into the WM_INT internal signalling mechanism's formulas. The "WM_INT::Pixel Shader Kill Pixel" signal is defined as: 3DSTATE_WM::ForceKillPixel == ON || (3DSTATE_WM::ForceKillPixel != Off && !WM_INT::WM_HZ_OP && 3DSTATE_WM::EDSC_Mode != PREPS && (WM_INT::Depth Write Enable || WM_INT::Stencil Write Enable) && ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ (3DSTATE_PS_EXTRA::PixelShaderKillsPixels || 3DSTATE_PS_EXTRA:: oMask Present to RenderTarget || 3DSTATE_PS_BLEND::AlphaToCoverageEnable || 3DSTATE_PS_BLEND::AlphaTestEnable || 3DSTATE_WM_CHROMAKEY::ChromaKeyKillEnable)) Because there is no depth or stencil buffer, writes to those buffers are disabled. So the highlighted condition is false, making the whole "Kill Pixel" condition false. This then feeds into the following "WM_INT::ThreadDispatchEnable" condition: 3DSTATE_WM::ForceThreadDispatch != OFF && !WM_INT::WM_HZ_OP && 3DSTATE_PS_EXTRA::PixelShaderValid && (3DSTATE_PS_EXTRA::PixelShaderHasUAV || WM_INT::Pixel Shader Kill Pixel || WM_INT::RTIndependentRasterizationEnable || (!3DSTATE_PS_EXTRA::PixelShaderDoesNotWriteRT && 3DSTATE_PS_BLEND::HasWriteableRT) || (WM_INT::Pixel Shader Computed Depth Mode != PSCDEPTH_OFF && (WM_INT::Depth Test Enable || WM_INT::Depth Write Enable)) || (3DSTATE_PS_EXTRA::Computed Stencil && WM_INT::Stencil Test Enable) || (3DSTATE_WM::EDSC_Mode == 1 && (WM_INT::Depth Test Enable || WM_INT::Depth Write Enable || WM_INT::Stencil Test Enable))) Given that there's no depth/stencil testing, no writeable render target, and the hardware thinks kill pixel doesn't happen, all of these conditions are false. We have to whack some bit to make PS invocations happen. There are many options. Curro suggested using the UAV bit. There's some precedence in doing that - we set it for fragment shaders that do SSBO/image/atomic writes when no color buffer writes are enabled. We can simply include discard here too.

The original behavior stated that no sRGB encoding should occur. The 4.4 behavior matches ES 3.0's wording. However, implementing the new behavior appears to break applications such as Left 4 Dead 2.

| | | | | | | | | | | | Because the rules for sRGB are so insane, we change brw_blorp_miptrees to take decode_srgb and encode_srgb flags, which control linearization of the source and destination separately. This should make it easy to implement whatever crazy combination of rules people throw at us. For now, it should be equivalent.

* meta: Make BlitFramebuffer() do sRGB encoding in ES 3.x.Kenneth Graunke2016-03-213-9/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | According to the ES 3.0 and GL 4.4 specifications, glBlitFramebuffer is supposed to perform sRGB decoding and encoding whenever sRGB formats are in use. The ES 3.0 specification is completely clear, and has always stated this. However, the GL specification has changed behavior in 4.1, 4.2, and 4.4. The original behavior stated that no sRGB encoding should occur. The 4.4 behavior matches ES 3.0's wording. However, implementing the new behavior appears to break applications such as Left 4 Dead 2. This patch changes Meta to apply the ES 3.x rules in ES 3.x, but leaves OpenGL alone for now, to avoid breaking applications. Meta implements several other functions in terms of BlitFramebuffer, and many of those explicitly do not perform sRGB encoding. So, this patch explicitly disables sRGB encoding in those other functions, preserving the existing (correct) behavior. If you're from the future and are reading this, hi! Welcome to the "fun" of debugging sRGB problems! Best of luck! Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Jordan Justen <[email protected]>
* i965: Stop XY clipping point and line primitives.Kenneth Graunke2016-03-181-1/+7
| | | | | | | | | | | | | | | | | | | | | | | Wide points and lines are not supposed to be clipped by the viewport. Rather, they should be rendered, and any fragments outside of the viewport should be discarded. The traditional use case for this behavior is rendering moving wide point particles. When the center of the point approaches the viewport edge, clipping would make it pop out of view early.

This scissoring hack ensures that any fragments generated are still restricted to the viewport.

| | | | | | | | | | | | | | | | | | | | | | | Thanks to James Legg for finding this! From the ARB_tessellation_shader spec: "The number of isolines generated is derived from the first outer tessellation level; the number of segments in each isoline is derived from the second outer tessellation level." According to the PRM, "TF.LineDensity determines # lines" while "TF.LineDetail determines # segments". Line Density is stored at DWord 6, while Line Detail is at DWord 7. So, they're not reversed like they are for triangles and quads. Fixes Piglit's spec/arb_tessellation_shader/execution/isoline, and about 24 dEQP isoline tests (with GL_EXT_tessellation_shader hacked on - it's not normally enabled).

* i965: Skip execution size adjustment for instructions of width 4Iago Toral Quiroga2016-03-171-1/+13
| | | | | | | | | | | | | | | | | | | | This code in brw_set_dest adjusts the execution size of any instruction with a dst.width < 8. However, we don't want to do this with instructions operating on doubles, since these will have a width of 4, but still need an execution size of 8 (for SIMD8). Unfortunately, we can't just check the size of the operands involved to detect if we are doing an operation on doubles, because we can have instructions that do operations on double operands interpreted as UD, operating on any of its 2 32-bit components. Previous commits have made it so we never emit instructions with a horizontal width of 4 that don't have the correct execution size set for gen6+, so we can skip it in this case, avoiding the conflicts with fp64 requirements. Expanding the same fix to other hardware generations requires many more changes but since we are not targetting fp64 support on them wer don't really care for now.
