The lowering pass was specialized to act on 64-bit to 32-bit conversions only,

We need to use 16-bit constants with 16-bit instructions,
otherwise we get the following validation error:
"Destination stride must be equal to the ratio of the sizes of
the execution data type to the destination type"
Because the execution data type is 4B due to the 32-bit integer
constant.

Always enable use of HW logical contexts to preserve GPU state between
batches when the kernel supports such constructs, continuing to enforce
the required support for gen6+.
At runtime, this effectively removes the BRW_NEW_CONTEXT flag (and the
upload of invariant state) from the start of every batch for any kernel
supporting contexts. So long as the older atoms are correctly listening
to the right flag (NEW_CONTEXT rather than NEW_BATCH) this should
eliminate a few redundant state uploads for the older platforms.
No piglits were harmed on ctg and ilk, both with and without logical
contexts.

This behaviour was changed in 1e5b09f42f. The commit message
for that says it is just a “tidy up” so my assumption is that the
behaviour change was a mistake. It’s a little hard to decipher looking
at the diff, but the previous code before that patch was:
if (builtin == SpvBuiltInFragCoord || builtin == SpvBuiltInSamplePosition)
nir_var->data.origin_upper_left = b->origin_upper_left;
if (builtin == SpvBuiltInFragCoord)
nir_var->data.pixel_center_integer = b->pixel_center_integer;
After the patch the code was:
case SpvBuiltInSamplePosition:
nir_var->data.origin_upper_left = b->origin_upper_left;
/* fallthrough */
case SpvBuiltInFragCoord:
nir_var->data.pixel_center_integer = b->pixel_center_integer;
break;
Before the patch origin_upper_left affected both builtins and
pixel_center_integer only affected FragCoord. After the patch
origin_upper_left only affects SamplePosition and pixel_center_integer
affects both variables.
This patch tries to restore the previous behaviour by changing the
code to:
case SpvBuiltInFragCoord:
nir_var->data.pixel_center_integer = b->pixel_center_integer;
/* fallthrough */
case SpvBuiltInSamplePosition:
nir_var->data.origin_upper_left = b->origin_upper_left;
break;
This change will be important for ARB_gl_spirv which is meant to
support OriginLowerLeft.

SPIR-V allows to define the shift, offset and count operands for
shift and bitfield opcodes with a bit-size different than 32 bits,
but in NIR the opcodes have that limitation. As agreed in the

Previously before fb077b0728, the LOD parameter was being used in place of the
sample index, which would only copy the first sample to all samples in the
destination image. After that multisample image copies wouldn't copy anything
from my observations.
This fixes some copy_and_blit CTS tests.

v2: - use GLSL_SAMPLER_DIM_MS instead of 2D (Samuel)

This unfortunately makes it malloc/realloc on every new batch, rather
than once at startup. But it ensures that the shadow buffer's size will
absolutely match the BO size. Otherwise, as we tune BATCH_SZ/STATE_SZ
or bufmgr cache bucket sizes, we may get a BO size that's rounded up,
and fail to allocate the shadow buffer large enough.
This doesn't fix any bugs today, as BATCH_SZ/STATE_SZ are the size of
a cache bucket, but it's better to be safe than sorry.
