A while back I switched intel_blit_framebuffer to prefer Meta over the
BLT. This meant that Gen8 platforms would start using the 3D engine
for blits, just like we do on Gen6-7.5.
However, I hadn't considered Gen4-5 when making that change. The BLT
engine appears to be substantially faster on 965GM than using Meta to
drive the 3D engine. This isn't too surprising: original Gen4 doesn't
support tile offsets (that came on G45), and the level/layer fields
don't work for cubemap rendering, so for inconvenient miplevel
alignments, we end up blitting or copying data to/from temporaries
in order to render to it. We may as well just use the blitter.
I chose to use the BLT on Gen4-5 because they use the same ring for
both 3D and BLT; Gen6+ splits it out.
Fixes regressions on 965GM due to botched tile offset code (we should
fix those properly as well, but they're longstanding bugs - for now,
put things back to the status quo).

System headers may contain C++ declarations, which cannot be given C
linkage. For this reason, include statements should never occur
inside extern "C".
This patch moves the C linkage statements to enclose only the
declarations within a single header.

The SSSE3 swizzling code was written for fast uploads to the GPU and
assumed the destination was always 16-byte aligned. When we began using
this code for fast downloads as well we didn't do anything to account
for the fact that the destination pointer given by glReadPixels() or
glGetTexImage() is not guaranteed to be suitably aligned.
With SSSE3 enabled (at compile-time), some applications would crash when
an SSE aligned-store instruction tried to store to an unaligned
destination (or an assertion that the destination is aligned would
trigger).
To remedy this, tell intel_get_memcpy() whether we're uploading or
downloading so that it can select whether to assume the destination or
source is aligned, respectively.

The header is included in ../xmlpool.h. With the latter of which used
directly in a number of places in mesa.
Note that we can also add it (alongside t_option.h) to noinst_HEADERS,
but neither solution fixes the issue that brough us here - namely:
Do not regenerate the headers, if it already exists.

The yoffset needs to be interpreted as a slice offset for 1D array
textures. This patch implements that by moving the yoffset into
zoffset similar to how it moves the height into depth.

Now that a layered source PBO is interpreted as a single tall 2D image
it's quite easy to accept the image height packing option by just
creating an image that is tall enough to include the image padding.
I'm not sure whether the image height property should affect 1D_ARRAY
textures. My intuition and interpretation of the GL spec (which is a
bit vague) would be that it shouldn't. However the software fallback
path in Mesa uses the property for packing but not for unpacking. The
binary NVidia driver uses it for both. This patch doesn't use it for
either case so it is different from the software fallback. There is
some discussion about this here:
http://lists.freedesktop.org/archives/mesa-dev/2015-February/077925.html
This is tested by the texsubimage Piglit test with the array and pbo
arguments. Previously this test was skipping this code path because it
always sets the image height.
I've also tested it by modifying the getteximage-targets test. It
wasn't using this code path before because it was using the default
texture object so this code couldn't successfully create a frame
buffer. I also modified it to add some image padding with the image
height in the PBO.

This reverts commit 546aba143d13ba3f993ead4cc30b2404abfc0202.
I think the changes to the calls to glBlitFramebuffer from this patch
are no different to what it was doing previously because it used to
set height to 1 before doing the blits. However it was introducing
some problems with the blit for layer 0 because this was no longer
special cased. It didn't fix problems with the yoffset which needs to
be interpreted as a slice offset. I think a better solution would be
to modify the original if statement to cope with the yoffset.

DRM_IOCTL_I915_GEM_WAIT takes an int64_t for the timeout value but
GL_ARB_sync takes an uint64_t. Further, the ioctl used to wait
indefinitely when passed a negative timeout, but it's been broken and
now returns immediately in that case. Thus, if an application passes
UINT64_MAX to wait forever, we overflow to -1LL and return immediately.
Work around this mess by clamping the wait timeout to INT64_MAX.

where possible.
The main objective of this change is to enable Linux developers to use
more of C99 throughout Mesa, with confidence that the portions that need
to be built with MSVC -- and only those portions --, stay portable.
This is achieved by using the appropriate -Werror= options only on the
places they need to be used.
Unfortunately we still need MSVC 2008 on a few portions of the code
(namely llvmpipe and its dependencies). I hope to eventually eliminate
this so that we can use C99 everywhere, but there are technical/logistic
challenges (specifically, newer Windows SDKs no longer bundle MSVC,
instead require a full installation of Visual Studio, and that has
hindered adoption of newer MSVC versions on our build processes.)
Thankfully we have more directy control over our OpenGL driver, which is
why we're now able to migrate to MSVC 2013 for most of the tree.

While using various debugging features (optimization debug, instruction dumping,
etc) this function is called in order to get a readable letter for the type of
unit.
On GEN8, two new units were added, the Qword and the Unsigned Qword (Q, and UQ
respectively). The existing assertion tries to determine that the argument
passed in is within the correct boundary, however, it was using UQ as the upper
limit instead of Q.
To my knowledge you can only hit this case with the branch I am currently
working on, so it doesn't fix any known issues.

I'm not really sure of the origins of the existing flag names. Modern docs have
some slightly different names. Having the correct names makes it easier to
determine if existing PIPE_CONTROL flag settings are correct, as well as making
adding new PIPE_CONTROLs easier.
This originally came up while I was trying to implement workarounds and spotted
some things called, "flush" which should have been called "invalidate."

This is a fix for a regression introduced in commit a9f8296d ("i965/fs:
Preserve the CFG in a few more places.").
The errata this code works around is described in a comment before the function:
"[DevBW, DevCL] Errata: A destination register from a send can not be
used as a destination register until after it has been sourced by an
instruction with a different destination register.
The framebuffer write's sources must be in message registers, which SEND
instructions cannot have as a destination. There's no way for this
errata to affect anything at the end of the program. Just remove the
code.

Previously, there were bugs where if the app set a scissor it could affect
the area of the texture that was downloaded. There was also potential that
the framebuffer SRGB state could affect downloads. This ensures that those
will get saved/restored and can't affect the texture download.
