mesa/tests: Sanity check the ES2 dispatch table

This test is only built when shared-glapi is used.  Because of changes
elsewhere in the tree that were necessary to make shared-glapi work
correct with GLX, it's not feasible to make the test function both ways.

The list of expected functions originally came from the functions set by
api_exec_es2.c.  This file no longer exists in Mesa (but api_exec_es1.c
is still generated).  It was the generated file that configured the
dispatch table for ES2 contexts.  This test verifies that all of the
functions set by the old api_exec_es2.c (with the recent addition of VAO
functions) are set in the dispatch table and everything else is a NOP.

When adding ES2 (or ES3) extensions that add new functions, this test
will need to be modified to expect dispatch functions for the new
extension functions.

i965: Do texture swizzling in hardware on Haswell.

Haswell supports EXT_texture_swizzle and legacy DEPTH_TEXTURE_MODE
swizzling by setting SURFACE_STATE entries.  This means we don't have to
bake the swizzle settings into the shader code by emitting MOV
instructions, and thus don't have to recompile shaders whenever the
swizzles change.

Unfortunately, we can't handle GL_ALPHA this way: unlike all the others,
which store the comparison result in the .r channel (and possibly others
as well), GL_ALPHA puts it in the .a channel.  The GLSL 1.30+ style
functions which return a float always simply return the .r channel,
which would be zero if we handled this as a surface override.  In this
case, fall back to doing it the old way.  DEPTH_TEXTURE_MODE = GL_ALPHA

i965/blorp: Fix sRGB MSAA resolves.

Commit e2249e8c4d06a85d6389ba1689e15d7e29aa4dff (i965/blorp: Add
support for blits between SRGB and linear formats) changed blorp to
always configure surface states for in linear format (even if the
underlying surface is sRGB).  This allowed sRGB-to-linear and
linear-to-sRGB blits to occur without causing the image to be
inappropriately brightened or darkened.

However, it broke sRGB MSAA resolves, since they rely on the
destination buffer format being sRGB in order to ensure that samples
are averaged together in sRGB-correct fashion.

This patch fixes the problem by instead configuring the source buffer
to use the *same* format as the destination buffer.  This ensures that
the image won't be brightened or darkened, but preserves proper sRGB
averaging.

Fixes piglit tests "EXT_framebuffer_multisample/accuracy srgb".

Paul Berry [Wed, 12 Sep 2012 18:13:49 +0000 (11:13 -0700)]
i965/blorp: Increase Y alignment for multisampled stencil blits.

This patch is a band-aid fix for a bug in commit 5fd67fa (i965/blorp:
Reduce alignment restrictions for stencil blits), which causes
multisampled stencil blits to work incorrectly on Sandy Bridge.

When blitting to or from a normal stencil buffer, we have to use a
coordinate transformation that swizzles coordinates to account for the
fact that stencil buffers use W tiling, but the most similar tiling
format available for textures and render targets is Y tiling.  The
differences between W and Y tiling cause pixels to be scrambled within
a block of size 8x4 (width x height) as measured relative to a W tile,
or 16x2 as measured relative to a Y tile.  So in order to make sure
that pixels at the edges of the blit aren't lost, we need to align the
rendering rectangle (and the buffer sizes) to multiples of the 8x4
block size.  This alignment happens in the brw_blorp_blit_params
constructor, whereas the determination of how to swizzle the
coordinates happens during code generation, in the
brw_blorp_blit_program class.

When blitting to or from a multisampled stencil buffer, the coordinate
swizzling is more complex, because it has to account for the
interleaving pattern of samples, which uses 4x4 blocks for 4x MSAA and
8x4 blocks for 8x MSAA.  The end result is that if multisampling is in
use, the 16x2 block size (relative so a Y tile) needs to be expanded
to 16x4, and the corresponding size relative to a W tile expands to
8x8.

The problem doesn't affect Ivy Bridge severely enough to crop up in
Piglit tests because on Ivy Bridge we have to disable multisampling
when blitting *to* a multisampled stencil buffer (the blorp compiler
generates code to compensate for the fact that multisampling is
disabled).  However I suspect a bug is still present because we don't
disable multisampling when blitting *from* a multisampled stencil
buffer.

This patch fixes the problem by doubling the vertical alignment
requirement when blitting to or from a multisampled stencil buffer,
and multisampling has not been disabled.

In the long run I would like to rework the brw_blorp_blit_params
constructor--it's difficult to follow and has had several subtle bugs
like this one.  However this band-aid fix should be suitable for
cherry-picking to release branches.

Fixes Piglit tests "unaligned-blit {2,4} stencil {msaa,upsample}" on
Sandy Bridge.
