glsl: validate global out xfb_stride qualifiers and set stride on empty buffers
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.

associated stride in the program object used for transform feedback

This default can be changed by declaring a different buffer with
xfb_buffer on the interface qualifier out. This is the only way
the global default can be changed. When a variable or output block
is declared without an xfb_buffer qualifier, it inherits the global
default buffer. When a variable or output block is declared with an

an xfb_buffer, but it must match the buffer inherited from its

The *xfb_buffer* qualifier follows the same conventions, behavior,

inheritance of the current global default buffer, a block member's
inheritance of the block's buffer, and the requirement that any

i965: Always use BRW_TEXCOORDMODE_CUBE when seamless filtering.
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.

i965: Fix brw_render_cache_set_check_flush's PIPE_CONTROLs.
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...

i965: Whack UAV bit when FS discards and there are no color writes.
dEQP-GLES31.functional.fbo.no_attachments.* draws a quad with no
framebuffer attachments, using a shader that discards based on
gl_FragCoord. 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.
