While looking through the documentation, I found this in the Sandybridge
PRM (Volume 4, Part 1, Page 140):
"Use of sample_c with SURFTYPE_CUBE surfaces is undefined with the
following surface formats: I24X8_UNORM, L24X8_UNORM, A24X8_UNORM,
I32_FLOAT, L32_FLOAT, A32_FLOAT."
I haven't observed this to be true, but it suggests that we may want to
use other formats.
We already perform DEPTH_TEXTURE_MODE swizzling in the shaders, and
don't rely on the surface format to splat things appropriately. So
using RED should work just as well as INTENSITY.
A few notes about the formats:
- R24_UNORM_X8_TYPELESS has the exact same properties as I24X8_UNORM.
- R16_UNORM and R32_FLOAT are additionally supported as a render target,
while the old I16_UNORM/I32_FLOAT formats are not.
- R32_FLOAT_X8X24_TYPELESS is not supported as a render target, while
the old format (R32G32_FLOAT) was. However, it shares the same
properties as the formats we use for Z24, so it should suffice.
This makes translate_tex_format and brw_blorp_surface_info::set
a bit more similar.
No Piglit changes on Sandybridge or Ivybridge. No oglconform changes on

Emitting flushes before depth and hiz resolves at the top of blorp's
state emission fixes the hang. Marchesin and I found the fix
experimentally, as opposed to adhering to a documented hardware
workaround. A more minimal fix likely exists, but this gets the job
done.

Broadwell allows us to specify an arbitrary value for QPitch, rather
than baking a specific formula into the hardware and requiring software
to lay things out to match. The only restriction is that the software
provided QPitch needs to be large enough so successive array slices do
not overlap.
In order to support this flexibility, software needs to specify QPitch
in a bunch of packets. Storing QPitch makes that easy, and allows us to
adjust it in a single place should we wish to change it in the future.

Broadwell introduces support for Q, UQ, and HF types. It also extends
DF support to allow immediate values.
Irritatingly, although HF and DF both support immediates, they're
represented by a different value depending on the register file.

On released hardware, values 4-6 are overloaded. For normal registers,
they mean UB/B/DF. But for immediates, they mean UV/VF/V.
Previously, we just created #defines for each name, reusing the same
value. This meant we could directly splat the brw_reg::type field into
the assembly encoding, which was fairly nice, and worked well.
Unfortunately, Broadwell makes this infeasible: the HF and DF types are
represented as different numeric values depending on whether the
source register is an immediate or not.
To preserve sanity, I decided to simply convert BRW_REGISTER_TYPE_* to
an abstract enum that has a unique value for each register type, and
write translation functions. One nice benefit is that we can add
assertions about register files and generations.
I've chosen not to convert brw_reg::type to the enum, since converting
it caused a lot of trouble due to C++ enum rules (even though it's
defined in an extern "C" block...).

Three-source instructions use a different encoding for register types
(and have a much more limited set to choose from).
Previously, we translated those into BRW_REGISTER_TYPE_* values, then
reused the existing reg_encoding mapping.
Doing it directly is more straightforward and actually less code.

calculate_attr_overrides is responsible for computing the point sprite
and flat-shading enable bitfields. It does so by OR'ing in a bunch of
bits. However, it relied on the caller to set the initial value to
zero. This is pretty fragile - if the caller neglects to zero out those
variables, then the enable bitfields end up full of garbage, which shows
up as random things being flat-shaded.
This patch moves the zero-initialization into calculate_attr_overrides,
so that the computation is completely in one place.
