| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here we use the built-in validation in ast_layout_expression::process_qualifier_constant() to check for mismatching global out strides on buffers in a single shader. From the ARB_enhanced_layouts spec: "While *xfb_stride* can be declared multiple times for the same buffer, it is a compile-time or link-time error to have different values specified for the stride for the same buffer." For intrastage validation a new helper link_xfb_stride_layout_qualifiers() is created. We also take this opportunity to make sure stride is at least a multiple of 4, we will validate doubles at a later stage. From the ARB_enhanced_layouts spec: "If the buffer is capturing any double-typed outputs, the stride must be a multiple of 8, otherwise it must be a multiple of 4, or a compile-time or link-time error results." Finally we update store_tfeedback_info() to apply the strides to LinkedTransformFeedback and update the buffers bitmask to mark any global buffers with a stride as active. For example a shader with: layout (xfb_buffer = 0, xfb_offset = 0) out vec4 gs_fs; layout (xfb_buffer = 1, xfb_stride = 64) out; Is expected to have a buffer bound to both 0 and 1. From the ARB_enhanced_layouts spec: "A binding point requires a bound buffer object if and only if its associated stride in the program object used for transform feedback primitive capture is non-zero."

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
