i965/gen6: Adjust render height in errata case for MSAA

In the gen6 PRM Volume 1 Part 1: Graphics Core, Section
7.18.3.7.1 (Surface Arrays For all surfaces other than separate
stencil buffer):

 "[DevSNB] Errata: Sampler MSAA Qpitch will be 4 greater than the

the affected heights, we increment the height by 1 for the rendering

vc4: Add support for blending.

Passes blendminmax and blendsquare.  glean's more serious blendFunc fails
in simulation due to binner memory overflow (I really need to work around
that), and fbo-blending-formats fails due to Mesa refusing one of the

supporting different formats yet.

vc4: Drop incorrect attempt to incorrectly invert the primconvert hw_mask.

The hw_mask is the set of primitives you actually support, so this attempt
to provide the set of formats that's unsupported was wrong in two ways (it
was intended to be '~' not '!').  However, we only call this code when
prim isn't one of the actually supported hw_mask bits, so missing out on

We were triggering simulator assertion failures for not consuming these,

like point/line antialiasing)

Note that this has the qreg index as 0, which is the same index as the
first GL varyings read.  This doesn't matter currently, since that number
isn't used for anything except dumping.

meta operations.

This works all the way back to gen7 where fast clear was introduced and
adds support for fast clear on gen8.  It replaces the blorp path
completely and improves on a few cases.  Layered clears are now done

_mesa_lock_texture() we can use _mesa_lock_context_textures(),

it's the same mutex, but if we made texture locking more fine grained

This all ignores the fact that texture locking seem a bit

i965: Fix INTDIV math assertions on Broadwell.

Commit c66d928f2c9fa59e162c391fbdd37df969959718 ("i965: Enable INTDIV
in SIMD16 mode.") began using generate_math_gen6 to break SIMD16 INTDIV
into two SIMD8 operations.

generate_math_gen6 takes two registers - for unary operations, we pass
ARF null for the second operand.  Prior to Broadwell, real operands were
always GRF.  But now they can be IMM as well.

So, check for != ARF instead of == GRF.

Revert "i965/vec4: Use MOV, not OR, to set URB write channel mask bits."

This reverts commit af13cf609f4257768ad8b80be8cec7f2e6ca8c81, which
appears to cause huge performance problems on Ivybridge.  I'd missed
that the FFTID bits are in the low byte.  The documentation doesn't
indicate that the URB write message header actually wants FFTID - it
just labels those bits as "Reserved."  But it appears necessary.

This does slightly more than revert the original change: originally,
Broadwell had separate code generation, which used MOV, and this patch
only changed it for Gen4-7.  Now that both are unified, reverting this
also makes Broadwell use OR.  Which should be fine.

the file descriptors.

Do not close the file descriptors passed in to eglCreateImageKHR with
EGL_LINUX_DMA_BUF_EXT target.

It is assumed, that the drivers, which ultimately process the file
descriptors, do not close or modify them in any way either. This avoids
the need to dup(), as it seems we would only need to just close the
dup'd file descriptors right after.
