When an instruction has a side effect, it impacts the available options when
reordering an instruction. As the EOT flag is an implied write to the render
target in the FS, it can be considered a side effect.
This patch shouldn't actually have any impact on the current code since the EOT
flag implies that the opcode is already one with side effects,
FS_OPCODE_FB_WRITE. The next patch however will introduce an optimization
whereby the EOT flag can occur with an opcode SHADER_OPCODE_TEX, and as that
instruction will perform the same implied write to the render target, it cannot
be reordered.

Commit e93566a15c changed the message header code needed to
make Skylake use SIMD4x2 so that it uses a register with width 4
instead of 8 as the source register in the send message. However it
also changed the width for the dest in the MOV instruction which is
used to initialise the header register with the values from g0. The
width of the destination is used to determine the exec size in
brw_set_dest so this would end up making the MOV have an exec size of
4. I think this would end up leaving the top half of the register
uninitialised. The top half of the header has meaningful values so
this probably isn't a good idea.
This patch just casts the dest register for the MOV instruction back
to a vec8 to fix it. It doesn't cause any changes to a Piglit run.

Commit b616164 added an optimization of b2f generation of a comparison.
It also included an extra optimization of one of the comparison values
is a constant of zero. The trick was that some value was known to be
zero, so that value could be used in the SEL instruction instead of
potentially loading 0.0 into a register.
This change switched the order of the arguments to the SEL, and, for
some unknown reason, I thought that the predicate should therefore
only be inverted for the == case. Clearly, it should always be
inverted.
Fixes piglit fs-notEqual-of-expression.shader_test and
fs-equal-of-expression.shader_test.
v2: Don't do the "register already has zero" optimization for the '== 0'

I finally managed to dig up some information on our mysterious GPU hangs.
A wiki page from the Crestline validation team mentions that they found
a GPU hang in "Serious Sam 2" (on Windows) with remarkably similar
conditions to the ones we've seen in Google Chrome and glmark2.
Apparently, if WM_STATE has "PS Use Source Depth" enabled, CC_STATE has
most depth state disabled, and you issue a CONSTANT_BUFFER command and
immediately draw, the depth interpolator makes a small mistake that
leads to hangs.
Most of the traces I looked at contained a CONSTANT_BUFFER packet
immediately followed by 3DPRIMITIVE, or at least very few packets.
It appears they also have "PS Use Source Depth" enabled - either at the
hang, or a little before it. So I think this is our bug.
The workaround is to emit a non-pipelined state packet after issuing a
CONSTANT_BUFFER packet. This is really similar to the workaround I
developed in commit c4fd0c9052.

For blitting, we want to fire off an RCL-only job. This takes a bit of
tweaking in our validation and the simulator support (and corresponding
new code in the kernel).
I want to be able to have multiple jobs being set up at the same time (for
example, a render job to do a little fixup blit in the course of doing a
render to the main FBO).
So, it turns out my simulator doesn't *quite* match the hardware. And the
errata about raster textures tells you most of what's wrong, but there's
still stuff wrong after that. Instead, if we're asked to sample from
raster, we'll just blit it to a tiled temporary.
Raster textures should only be screen scanout, and word is that it's
faster to copy to tiled using the tiling engine first than to texture from
an entire raster texture, anyway.
These are required to get piglit's idiv tests working. The
unsigned<->float conversions are wrong, but are good enough to get
piglit's small ranges of values working.
We create textures internally for texsubimage, and we use
the values from sub image to create a new texture, however
we don't align these to valid sizes, and cube map arrays
must have an array size aligned to 6.
This fixes texsubimage cube_map_array on CAYMAN at least,
(it was causing GPU hang and bad values), it probably
also fixes it on radeonsi and evergreen.

Coverity is confused by the "float < int / 2" expression and suggests

Allow glEGLImageTargetRenderbufferStorageOES and
glEGLImageTargetTexture2DOES for dma_buf EGLImages if the image is
a single RGBA8 unorm plane. This is safe, despite fast color clears,
because i965 disables allocation of auxiliary buffers for EGLImages.
Chrome OS needs this, because its compositor uses dma_buf EGLImages for
its scanout buffers.

- Tested on Ivybridge Chromebook Pixel with WebGL Aquarium and
YouTube.
- No Piglit regressions on Broadwell with `piglit run -p gbm
tests/quick.py`, with my Piglit patches that update the

EGL does not yet have extensions to manage the flushing and invalidating

This patch is obviously needed for renderbufers. It's also needed for
textures because the user can attach the texture to a framebuffer and
because the driver sometimes renders to textures for internal reasons.

We need this field to safely render to a buffer that was imported with

Every caller of this function uses it to determine if the current
miptree needs a hiz buffer to be allocated. Strangely, the function
doesn't take a miptree argument. So, this function effectively decides
if and when a miptree's hiz buffer gets allocated without inspecting the
miptree itself. Luckily, the driver behaves correctly despite the
brw_is_hiz_depth_format's quirk.
I will soon make some changes to the miptree that will require
inspecting the miptree to determine if it needs a hiz buffer. So this
patch renames
brw_is_hiz_depth_format -> intel_miptree_wants_hiz_buffer
and gives it a miptree parameter.
This patch shouldn't change any behavior.
